Digestive specialists Abdominal Ultrasound: What It Checks and What to Expect An abdominal ultrasound uses sound waves to image the liver, gallbladder, bile ducts, spleen, kidneys, and portions of the pancreas and aorta. It is painless, uses no radiation, and is commonly ordered to evaluate abdominal pain, abnormal lab results, or suspected gallstones and liver disease. Digestive specialists | education Digestive specialists Acid Reflux Symptoms: How to Recognize GERD Acid reflux occurs when stomach acid travels into the esophagus, causing heartburn — a burning sensation behind the breastbone — along with regurgitation of food or liquid and sometimes a sour or bitter taste. When symptoms occur twice a week or more, the condition is classified as GERD and warrants evaluation. Digestive specialists | seek-care Digestive specialists Anal Fissure: Symptoms, Causes, and Treatment Options An anal fissure is a small tear in the lining of the anal canal that causes sharp pain and sometimes bleeding during or just after a bowel movement. Most anal fissures heal within weeks with conservative care — stool softeners, sitz baths, and topical treatments. A specialist is needed when self-care is insufficient. Digestive specialists | seek-care Digestive specialists Barrett's Esophagus: What It Is, Symptoms, and Cancer Risk Barrett's esophagus is a change in the lining of the lower esophagus caused by long-term exposure to stomach acid. It can develop in people with chronic GERD and raises the risk of a specific type of esophageal cancer. Regular endoscopic surveillance managed by a gastroenterologist is the cornerstone of care. Digestive specialists | education Digestive specialists Best Probiotics for IBS: What the Evidence Actually Shows Some probiotic strains show modest benefit for IBS in clinical studies, but the overall evidence is mixed — results vary by strain, IBS subtype, and individual response. No single probiotic product has strong, consistent proof of IBS relief. Probiotics are best considered alongside other evidence-based treatments under guidance from a gastroenterologist. Digestive specialists | medication Digestive specialists Bloating After Every Meal: Common Causes and What Helps Bloating after every meal is common and usually has a benign cause — swallowed air, fermentation of certain carbohydrates by gut bacteria, food intolerances, or a sensitive digestive tract like IBS. When bloating occurs consistently after most meals, a gastroenterologist can identify the specific cause and guide effective relief. Digestive specialists | seek-care Digestive specialists C. diff (Clostridioides difficile) Symptoms and When to Get Help C. diff (Clostridioides difficile) is a bacterial colon infection that causes watery diarrhea — typically three or more loose stools per day — along with abdominal cramping. It most commonly follows antibiotic use. C. diff is treatable but can become serious; anyone with significant diarrhea after antibiotics should see a clinician promptly. Digestive specialists | seek-care Digestive specialists Celiac Disease Blood Test: What to Ask Your Doctor For The primary celiac disease blood test is the tissue transglutaminase IgA antibody (tTG-IgA), ordered alongside a total serum IgA to confirm the test's validity. You must be eating gluten regularly — not on a gluten-free diet — for accurate results. A positive result is confirmed by small intestinal biopsy with a gastroenterologist. Digestive specialists | seek-care Digestive specialists Celiac Disease Diagnosis: Blood Tests, Biopsy, and What to Expect Celiac disease is diagnosed in two steps: a tTG-IgA blood test detects immune antibodies to gluten, then a small intestinal biopsy during endoscopy confirms lining damage. Both steps require continued gluten consumption — stopping gluten before testing makes accurate diagnosis much harder. Digestive specialists | education Digestive specialists Chronic Acid Reflux: When Should You See a GI Doctor? Acid reflux is called GERD when it occurs more than twice a week or persists despite over-the-counter medications. A gastroenterologist should evaluate GERD that doesn't respond to treatment, lasts more than several weeks, or is accompanied by difficulty swallowing, weight loss, or other warning signs. Digestive specialists | seek-care Digestive specialists Chronic Bloating and Gas Every Day: Causes and Solutions Bloating and gas every day is rarely dangerous but is a real quality-of-life issue. The most common causes are irritable bowel syndrome, food intolerances — especially to lactose or fructose — and high-fermentation foods. A gastroenterologist can run targeted breath or lab tests when pattern-tracking at home doesn't resolve symptoms. Digestive specialists | seek-care Digestive specialists Chronic Heartburn and Esophageal Cancer Risk Persistent, untreated GERD — especially over many years — can cause Barrett's esophagus, a change in the esophageal lining that carries elevated risk for esophageal adenocarcinoma. Most people with GERD will not develop cancer, but ongoing or poorly controlled symptoms warrant evaluation by a GI specialist. Digestive specialists | education Digestive specialists Chronic Pancreatitis Treatment and Pain Management Chronic pancreatitis treatment is managed by a gastroenterologist and typically involves pain control, pancreatic enzyme replacement therapy (PERT) to restore digestion, nutrition support, and strict alcohol and tobacco cessation. Endoscopic or surgical intervention may be needed when pain cannot be controlled with medication alone. Digestive specialists | education Digestive specialists Clear Liquid Diet for Colonoscopy Prep: What You Can Eat On colonoscopy prep day, allowed clear liquids include water, clear broths, plain gelatin, pulp-free fruit juice, clear sports drinks, popsicles without fruit or cream, and black coffee or tea. Avoid anything red, purple, or blue, as well as dairy, solid food, and alcohol — colors can interfere with the colonoscopy view. Digestive specialists | education Digestive specialists Colon Polyps Found on Colonoscopy: What They Mean A colon polyp is a small growth on the lining of the colon or rectum. Most are benign, but adenomas can become cancerous if not removed. When polyps are found and removed during colonoscopy, the procedure is working as intended. The type and number found determine how soon you need your next colonoscopy. Digestive specialists | education Digestive specialists Colonoscopy Alternatives for Colon Cancer Screening Colonoscopy is the most thorough colon cancer screening test, but FIT (annual stool blood test), stool DNA testing (Cologuard), and CT colonography are guideline-endorsed non-invasive alternatives for average-risk adults starting at age 45. Each option differs in detection accuracy, convenience, and what follow-up is needed if results are abnormal. Digestive specialists | education Digestive specialists Colonoscopy Cost Without Insurance: What to Expect A colonoscopy without insurance typically costs between $1,500 and $4,500, depending on facility type and location. Hospital outpatient departments charge more than ambulatory surgery centers. Federal price transparency rules require facilities to post cash prices — asking upfront can reduce costs significantly. For average-risk screening, stool-based tests are a less expensive, guideline-endorsed alternative. Digestive specialists | billing Digestive specialists Constipation for a Week: Should You Be Worried? Not having a bowel movement for a week is uncomfortable but usually not an emergency for otherwise healthy adults. Common causes include low fiber intake, dehydration, inactivity, travel, medications, and stress. Constipation lasting more than two to three weeks, or accompanied by rectal bleeding, weight loss, or significant pain, warrants medical evaluation. Digestive specialists | seek-care Digestive specialists Crohn's Disease Foods to Avoid: Triggers and Diet Tips No specific food causes Crohn's disease, but high-fiber foods, high-fat foods, dairy, caffeine, and alcohol commonly worsen symptoms during active disease. During a flare, low-fiber, easily digestible foods are generally better tolerated. An IBD-focused dietitian can help identify individual triggers and prevent nutritional deficiencies. Digestive specialists | education Digestive specialists Crohn's Disease Treatment Options Explained Crohn's disease treatment includes corticosteroids for flares, immune modulators (azathioprine, methotrexate) for maintenance, and biologic therapies (anti-TNF, vedolizumab, ustekinumab) for moderate to severe disease. Between 30–55% of patients require surgery within 10 years. The goal of modern therapy is mucosal healing, not just symptom control. Digestive specialists | education Digestive specialists Crohn's Flare Up: What to Do and When to Seek Care A Crohn's disease flare is a return or worsening of symptoms — abdominal cramping, diarrhea, fatigue, or urgency — after remission. During a mild flare, rest the bowel, stay hydrated, and contact your gastroenterologist early. Some flares require prescription adjustments; others signal a complication that needs prompt evaluation. Digestive specialists | seek-care Digestive specialists Crohn's vs Ulcerative Colitis: Key Differences Explained Crohn's disease can inflame any part of the digestive tract through all layers of the bowel wall. Ulcerative colitis affects only the inner lining of the large intestine. Both are types of inflammatory bowel disease (IBD) but differ in location, pattern, complications, and some treatments. Long-standing IBD — especially extensive ulcerative colitis — raises the long-term risk of colorectal cancer and requires regular surveillance colonoscopy. Digestive specialists | education Digestive specialists Diarrhea for Weeks: Causes and When to See a Doctor Diarrhea lasting more than four weeks is considered chronic and requires medical evaluation. Common causes include irritable bowel syndrome, food intolerances, inflammatory bowel disease, celiac disease, infections, and medication effects. Blood in the stool, unintended weight loss, or symptoms that wake you at night require prompt evaluation by a gastroenterologist. Digestive specialists | seek-care Digestive specialists Diverticulitis and Antibiotics: What the Evidence Shows Mild, uncomplicated diverticulitis in otherwise healthy adults can often be managed without routine antibiotics, per current evidence and American College of Physicians guidelines. Severe or complicated cases — with fever, significant pain, elevated infection markers, abscess, or perforation — do require antibiotics and sometimes hospitalization. Digestive specialists | medication Digestive specialists Diverticulitis Diet: What to Eat During and After a Flare During an acute diverticulitis flare, start with clear liquids to rest the inflamed colon, then advance to low-fiber foods as symptoms improve. Once fully recovered, transition to a high-fiber diet — the best evidence-based strategy for preventing future episodes, per NIDDK and the American College of Physicians. Digestive specialists | education Digestive specialists Diverticulitis Symptoms and Treatment: What to Know Diverticulitis is inflammation — and sometimes infection — of small pouches (diverticula) in the colon wall. Classic symptoms include left lower abdominal pain, fever, and bowel habit changes. Severity ranges from mild, manageable at home with dietary modification and selective antibiotics, to serious cases requiring hospitalization or surgery. Digestive specialists | seek-care Digestive specialists Elevated Liver Enzymes: What High AST and ALT Mean Elevated liver enzymes — most often AST and ALT — indicate that liver cells are under stress, but a mildly raised result on a single test does not confirm serious disease. The most common cause in U.S. adults is fatty liver (MASLD). The next step is typically repeat testing and a clinician conversation to identify the underlying reason. Digestive specialists | education Digestive specialists Endoscopy vs Colonoscopy: What Is the Difference? An upper endoscopy (EGD) examines the esophagus, stomach, and the first part of the small intestine via a camera inserted through the mouth. A colonoscopy examines the large intestine and rectum via the other end. Both use a flexible camera; which procedure is ordered depends on your symptoms. Digestive specialists | education Digestive specialists Eosinophilic Esophagitis (EoE): Symptoms and Treatment Eosinophilic esophagitis (EoE) is a chronic immune-mediated condition where eosinophils accumulate in the esophagus, causing inflammation, narrowing, and difficulty swallowing. Food getting stuck in the throat or chest is a hallmark symptom. Diagnosis requires endoscopy with biopsies. Management includes dietary elimination, swallowed steroids, and — since 2022 — dupilumab, the first FDA-approved drug for EoE. Digestive specialists | seek-care Digestive specialists External Hemorrhoids: Treatment and How Long They Last External hemorrhoids form outside the anal sphincter and cause pain, itching, and swelling. Most uncomplicated cases resolve within one to two weeks with warm sitz baths, high-fiber diet, adequate hydration, and over-the-counter topical preparations. A thrombosed (clotted) external hemorrhoid is more painful and may benefit from early office excision within 72 hours. Digestive specialists | medication Digestive specialists Fatty Liver Disease Symptoms: Signs of NAFLD/MASLD Fatty liver disease (MASLD/NAFLD) typically causes no symptoms in early stages — most diagnoses are incidental findings on blood tests or imaging. When symptoms appear, fatigue and vague discomfort under the right rib cage are most common. The absence of symptoms does not mean the condition is not progressing. Digestive specialists | seek-care Digestive specialists Fecal Transplant (FMT): What It Is and What It Treats Fecal microbiota transplantation (FMT) transfers stool from a healthy donor into a patient's digestive tract to restore balanced gut bacteria. Its strongest evidence is for recurrent Clostridioides difficile (C. diff) infection, where FDA-approved products (Rebyota, Vowst) are now available. Its role in IBS and inflammatory bowel disease is still under investigation. Digestive specialists | education Digestive specialists First GI Specialist Appointment: What to Expect At a first gastroenterology appointment, the doctor takes a detailed digestive symptom history, reviews medical records, performs a physical exam, and outlines a diagnostic plan. This may include bloodwork, imaging, or scheduling an endoscopy or colonoscopy. Most first visits last 30–60 minutes. Arriving with a symptom log and medication list helps make the most of the visit [1]. Digestive specialists | scheduling Digestive specialists Gallbladder Attack Symptoms: What It Feels Like and When to Act A gallbladder attack (biliary colic) causes sudden, cramping or steady severe pain in the upper right or center of the abdomen — often starting 30–60 minutes after a fatty meal and sometimes radiating to the right shoulder blade or back. Most attacks last 30 minutes to a few hours, then ease. Fever or jaundice are emergency warning signs. Digestive specialists | seek-care Digestive specialists Gallbladder Removal Recovery: What to Expect Most people recover from laparoscopic gallbladder removal — the approach used in the vast majority of cases — within one to two weeks. Open surgery typically requires four to six weeks of recovery. Your surgeon's specific instructions take priority over any general timeline. Digestive specialists | education Digestive specialists Gallstone Pancreatitis: Symptoms and Treatment Gallstone pancreatitis occurs when a gallstone blocks the duct connecting the gallbladder and pancreas, triggering sudden inflammation. It causes severe upper abdominal pain that often radiates to the back, plus nausea and vomiting. It is the most common identifiable cause of acute pancreatitis and requires hospital evaluation. Digestive specialists | education Digestive specialists Gallstones Symptoms: Signs, Pain, and When to Act Gallstones often cause no symptoms at all. When they do, the hallmark is sudden cramping pain in the upper right abdomen or belly center — sometimes radiating to the right shoulder or back — that comes on after a fatty meal and lasts 30 minutes to a few hours, often with nausea and vomiting. Digestive specialists | seek-care Digestive specialists Gallstones Without Surgery: Non-Surgical Options Explained Laparoscopic cholecystectomy is the most effective treatment for symptomatic gallstones. Non-surgical options like ursodiol (bile acid therapy) work only for certain stone types, and gallstones commonly recur once treatment stops. They are reserved for patients who cannot safely undergo surgery. Digestive specialists | education Digestive specialists Gastritis Symptoms: What Is Gastritis and How Is It Treated? Gastritis is inflammation of the stomach's inner lining causing gnawing or burning upper-abdominal pain, nausea, and bloating. Symptoms overlap with acid reflux and peptic ulcers, so a clinician is needed to determine the cause — which may include H. pylori infection, NSAIDs, or alcohol use. Digestive specialists | seek-care Digestive specialists GERD Treatment Without Medication: Lifestyle Changes That Help Lifestyle changes are the recommended first-line treatment for GERD. Weight loss (if overweight), elevating the head of the bed by 15–20 cm, avoiding trigger foods, eating smaller meals, and not lying down within two to three hours of eating all have guideline-level evidence supporting meaningful symptom reduction without medication [1][2]. Digestive specialists | education Digestive specialists Gluten-Free Diet for Celiac Disease: A Practical Guide A strict, lifelong gluten-free diet is the only effective treatment for celiac disease. Even small amounts of gluten — found in wheat, barley, and rye — can cause intestinal damage, even without obvious symptoms. Cross-contamination and hidden gluten in sauces, medications, and processed foods are common pitfalls. Digestive specialists | education Digestive specialists H. Pylori Symptoms, Testing, and Treatment Explained H. pylori is a bacterial infection of the stomach lining that is a leading cause of peptic ulcers and chronic gastritis. Many people have no symptoms, but it can cause stomach pain, nausea, and bloating. It is diagnosed with a breath, stool, or biopsy test and treated with a short antibiotic course plus acid suppression. Digestive specialists | seek-care Digestive specialists Hemorrhoid Banding: What to Expect Before and After Hemorrhoid banding (rubber band ligation) is a brief outpatient procedure where a small elastic band is placed at the base of an internal hemorrhoid, cutting off its blood supply. The hemorrhoid shrinks and falls off within one to two weeks. ASCRS guidelines recognize it as the most effective office-based treatment for symptomatic internal hemorrhoids [1][2]. Most patients experience mild pressure rather than sharp pain and return to normal activity within a day or two. Digestive specialists | education Digestive specialists Hemorrhoids: Symptoms, Home Treatment, and When to See a Doctor Hemorrhoids are swollen vascular cushions in the lower rectum or around the anus that cause bleeding, itching, and discomfort. About 1 in 20 Americans are affected, and roughly half of adults over 50 experience them at some point [2]. Most cases improve with dietary fiber, increased fluids, sitz baths, and over-the-counter creams. Persistent or heavy rectal bleeding always warrants a provider evaluation to rule out other causes [1][3]. Digestive specialists | seek-care Digestive specialists Hiatal Hernia Symptoms, GERD Connection, and Treatment A hiatal hernia occurs when part of the stomach pushes upward through the diaphragm into the chest. The most common type — a sliding hiatal hernia — often causes no symptoms alone, but it weakens the anti-reflux valve, leading to chronic heartburn and GERD. Treatment ranges from lifestyle changes and acid suppression medication to laparoscopic surgery, depending on severity [1][2]. Paraesophageal hernias are less common but carry a higher risk of complications and often require surgical repair [3]. Digestive specialists | seek-care Digestive specialists How a Gastroenterologist Diagnoses IBS: Tests and Criteria IBS is a clinical diagnosis — no single test confirms it. Gastroenterologists apply the Rome IV symptom criteria, take a detailed history, and use selective blood tests or stool tests to rule out other conditions like celiac disease or IBD. Most patients with classic IBS symptoms do not need a colonoscopy as part of the initial workup. Digestive specialists | education Digestive specialists How Much Does a Colonoscopy Cost? (With & Without Insurance) A colonoscopy typically costs $1,500–$4,500 out of pocket depending on the facility and whether polyps are removed. Most guidelines now recommend screening starting at age 45 for average-risk adults [1][2]. Preventive colonoscopies are often covered at 100% by qualifying insurance plans under the ACA. Diagnostic colonoscopies — ordered for symptoms — trigger standard cost-sharing. Digestive specialists | billing Digestive specialists How Often Should You Get a Colonoscopy? Screening Guidelines Current guidelines recommend most average-risk adults begin colonoscopy screening at age 45 and repeat every 10 years if no polyps are found. Those with a family history of colorectal cancer, a personal history of polyps, or inflammatory bowel disease may need earlier and more frequent screening. Digestive specialists | education Digestive specialists How Serious Is Acute Pancreatitis? Severity and Risks Acute pancreatitis ranges widely in severity. About 80% of cases are mild and resolve with a few days of hospital support. However, a significant minority develop severe disease involving organ failure, infected pancreatic tissue, or life-threatening complications. All cases require prompt medical evaluation; severe cases are managed in hospital, often in an ICU. Digestive specialists | education Digestive specialists How to Find a Gastroenterologist Near You To find a gastroenterologist near you, use your insurance plan's online directory, ask your primary care provider for a referral, or search the American College of Gastroenterology's physician finder at gi.org [1]. Most GI specialists require a referral for insurance coverage, though some practices accept direct bookings. Colonoscopy is one of the most common reasons for referral, and the ACG recommends colorectal cancer screening starting at age 45 for average-risk adults [2]. Digestive specialists | scheduling Digestive specialists How to Get Rid of Acid Reflux Fast: Relief and Treatment For immediate acid reflux relief, antacids such as calcium carbonate work within minutes by neutralizing stomach acid in the esophagus [3]. Sitting upright also helps quickly. For frequent reflux or GERD, H2 blockers and proton pump inhibitors treat the underlying acid overproduction more durably, and both the ACG and AGA guidelines support PPIs as first-line therapy for frequent GERD [1][2]. Digestive specialists | medication Digestive specialists How to Maintain Ulcerative Colitis Remission Maintaining ulcerative colitis remission requires staying on prescribed maintenance therapy — most relapses occur when people stop medication after feeling well. A gastroenterologist selects the right drug, such as 5-ASA or a biologic, and a monitoring schedule, including surveillance colonoscopy, to keep inflammation controlled and lower long-term cancer risk. Digestive specialists | medication Digestive specialists How to Prepare for a Colonoscopy: Step-by-Step Guide Colonoscopy preparation takes one to two days. It begins with a low-residue diet two to three days before, followed by a clear liquid phase and a prescription bowel-cleansing solution. A thorough prep is essential — a clean colon lets the doctor see the entire lining and find polyps that might otherwise be missed. Digestive specialists | education Digestive specialists How to Prevent Diverticulitis Flare-Ups: Diet and Lifestyle A high-fiber diet, adequate hydration, regular physical activity, and avoiding smoking and obesity are evidence-backed strategies to reduce diverticulitis flare frequency [1]. Contrary to older guidance, current guidelines do not support avoiding seeds, nuts, or popcorn — those foods may actually be part of a healthy high-fiber diet [1][2]. Digestive specialists | education Digestive specialists How to Reverse Fatty Liver Disease (MASLD/NAFLD): What Works Fatty liver disease (MASLD) can often be significantly improved or reversed through sustained lifestyle changes. Losing 7 to 10 percent of body weight via caloric reduction and regular exercise consistently reduces liver fat and, in many people, reverses early-stage disease. No medication is specifically approved for MASLD as of 2026. Digestive specialists | education Digestive specialists IBS and Anxiety: Understanding the Gut-Brain Connection IBS and anxiety share a two-way gut-brain axis: anxious thoughts trigger abdominal pain, cramping, and bowel changes, while gut discomfort heightens anxiety in return [1]. The NIDDK now classifies IBS as a disorder of gut-brain interaction [3]. Breaking this loop is central to IBS management and often involves treatments that address both the digestive system and the nervous system simultaneously. Digestive specialists | education Digestive specialists IBS Diet: Foods to Avoid and What May Help IBS food triggers vary by person, but the low-FODMAP diet has the strongest evidence for symptom relief in IBS [1][2]. The ACG guideline recommends soluble fiber over insoluble fiber and cautions that wheat bran may worsen symptoms [1]. Systematic food-diary tracking and a structured elimination diet are more reliable than blanket avoidance of commonly listed trigger foods. Digestive specialists | education Digestive specialists IBS vs Crohn's Disease: Key Differences Explained IBS and Crohn's disease both cause abdominal pain and bowel changes, but they are fundamentally different: IBS involves no bowel damage and is classified as a disorder of gut-brain interaction [1][3], while Crohn's is a chronic inflammatory condition that causes visible bowel damage and serious complications if untreated [2]. A gastroenterologist can distinguish them through colonoscopy, imaging, and blood tests. Digestive specialists | education Digestive specialists IBS with Constipation (IBS-C): Treatment Options Explained IBS with constipation (IBS-C) is treated with a combination of soluble fiber, adequate hydration, and — when lifestyle measures fall short — prescription secretagogues like linaclotide or plecanatide that are FDA-approved specifically for IBS-C [2]. Dietary adjustments and stress management are important complements to any medication plan [1]. Digestive specialists | medication Digestive specialists IBS with Diarrhea (IBS-D): How to Manage Symptoms IBS with diarrhea (IBS-D) is managed through dietary trigger avoidance, particularly low-FODMAP eating, alongside over-the-counter antidiarrheals [1]. When symptoms are persistent or severe, prescription medications including rifaximin and eluxadoline target both urgency and abdominal pain specifically in IBS-D [2]. A gastroenterologist can confirm the diagnosis and match treatment to your symptom pattern. Digestive specialists | medication Digestive specialists Liver Biopsy: What to Expect Before, During, and After A liver biopsy removes a small tissue sample with a needle for microscopic examination. The procedure typically takes under 30 minutes, and patients recover at the clinic for 2 to 4 hours. Major complications occur in roughly 1.6% of procedures. It is most often ordered by a hepatologist to stage fibrosis from NASH or cirrhosis. Digestive specialists | education Digestive specialists Liver Cirrhosis: Early Signs and When to See a Specialist Early cirrhosis frequently produces no symptoms, which is what makes early detection treatable. When symptoms emerge, they typically include fatigue, mild upper-right abdominal discomfort, and easy bruising. Advanced cirrhosis produces serious signs including ascites, jaundice, and confusion — all requiring hepatologist evaluation. Digestive specialists | seek-care Digestive specialists Long-Term PPI Risks: Is Daily Omeprazole Safe? Long-term daily PPI use has been associated with low magnesium, vitamin B12 deficiency, and a modest increase in fracture risk, along with weaker signals for kidney disease and infection. For most people with a clear indication the benefits outweigh these concerns, but a periodic clinician review helps confirm whether continued use is still appropriate or the dose can be reduced. Digestive specialists | medication Digestive specialists Low-FODMAP Diet Guide for IBS: How to Start The low-FODMAP diet is a three-phase protocol — elimination, reintroduction, and personalization — designed to identify fermentable carbohydrates that trigger IBS symptoms. It has the strongest evidence base of any dietary approach for IBS, with significant symptom relief during elimination, and works best under registered dietitian supervision. Digestive specialists | education Digestive specialists NASH Liver Disease Treatment Options (2024 Guide) NASH (nonalcoholic steatohepatitis) treatment centers on meaningful weight loss and controlling metabolic risk factors like diabetes and high triglycerides. The FDA approved the first drug specifically for NASH with liver fibrosis in 2024. A gastroenterologist or hepatologist should guide the overall care plan, which may also include weight-loss medications. Digestive specialists | education Digestive specialists Nausea After Eating: Causes and When to See a Doctor Nausea after eating is most commonly caused by gastroparesis (delayed stomach emptying), gastritis, acid reflux, food intolerances, or functional dyspepsia. When nausea occurs frequently, is severe, or accompanies vomiting, unexplained weight loss, or persistent pain, evaluation by a primary care provider or gastroenterologist is appropriate. Digestive specialists | seek-care Digestive specialists Pancreatitis Diet: What to Eat and What to Avoid The cornerstone of pancreatitis dietary management is a low-fat, small-portion eating pattern that reduces the workload on the pancreas. Alcohol must be avoided entirely as it is both a trigger and an aggravator. A registered dietitian working alongside a gastroenterologist can tailor specific guidance for acute recovery versus chronic disease management. Digestive specialists | education Digestive specialists Pancreatitis Symptoms: Signs of Acute and Chronic Disease Pancreatitis typically causes sudden, severe pain in the upper abdomen or mid-back, accompanied by nausea and vomiting. Acute pancreatitis comes on rapidly and requires immediate hospital evaluation. Chronic pancreatitis produces recurring or persistent abdominal pain alongside digestive problems. Sudden severe upper abdominal pain should be evaluated in an emergency setting without delay. Digestive specialists | seek-care Digestive specialists Rectal Bleeding: When Should You Be Worried? Rectal bleeding always deserves evaluation. While hemorrhoids are the most common cause, it can also signal polyps, inflammatory bowel disease, diverticular disease, or colorectal cancer. New rectal bleeding in an adult should prompt a clinician visit; some presentations need urgent care. Digestive specialists | seek-care Digestive specialists SIBO Breath Test: What to Expect Before and During A SIBO breath test measures hydrogen and methane gases exhaled after drinking a sugar solution. The test takes two to three hours, requires a strict low-fermentation prep diet the day before, and is ordered and interpreted by a gastroenterologist. Most patients find the test itself painless; the prep is what determines accuracy. Digestive specialists | education Digestive specialists SIBO Symptoms: Bloating, Gas, and What Else to Watch For The most common SIBO symptoms are persistent bloating — often worsening through the day — along with excessive gas, abdominal discomfort, and stool changes. Because these overlap significantly with IBS, a gastroenterologist's evaluation is needed to distinguish SIBO from other causes. Digestive specialists | seek-care Digestive specialists SIBO Treatment: Antibiotics, Diet, and What to Expect SIBO is most commonly treated with rifaximin — a minimally absorbed antibiotic — often for a 14-day course, with methane-dominant disease (IMO) requiring the addition of neomycin. Diet alone cannot eliminate bacterial overgrowth, but low-FODMAP changes reduce the fermentation load and improve symptoms during and after treatment. Digestive specialists | medication Digestive specialists Small Bowel Bacterial Overgrowth: Testing Options Explained The standard test for small intestinal bacterial overgrowth is the hydrogen and methane breath test, performed by drinking a sugar solution and collecting exhaled air at intervals. Direct endoscopic aspirate culture is the reference standard but reserved for complex cases. Digestive specialists | education Digestive specialists Stage 3 Fatty Liver Disease (Fibrosis): What It Means Stage 3 fatty liver disease means bridging fibrosis — significant scarring that links liver units together. It is serious but potentially reversible with weight loss, metabolic control, and, since March 2024, resmetirom — the first FDA-approved drug for MASH with moderate to advanced fibrosis. A hepatologist is the right specialist for ongoing management. Digestive specialists | education Digestive specialists Stomach Pain After Eating Every Time: Common Causes Consistent pain after every meal — especially in the upper abdomen — often has a diagnosable GI cause. The most common include acid reflux, gastritis, peptic ulcers, and functional dyspepsia. The pattern, location, and timing of pain help a clinician narrow the diagnosis. Digestive specialists | seek-care Digestive specialists Stomach Ulcer Diet: What to Eat and What to Avoid No single diet heals a stomach ulcer, but certain foods worsen pain by increasing acid or irritating a damaged lining. Diet helps manage symptoms during medical treatment — not instead of it. H. pylori and NSAID-related ulcers require medication first. Digestive specialists | education Digestive specialists Symptoms of Crohn's Disease: Early Signs and Flares Crohn's disease most commonly causes persistent diarrhea, abdominal cramping, and fatigue that come and go in flares. It can affect any part of the GI tract but most often involves the end of the small intestine. Diagnosis is confirmed by a gastroenterologist with endoscopy and biopsy. Digestive specialists | seek-care Digestive specialists Ulcerative Colitis Diet: What to Eat and Avoid No single diet controls ulcerative colitis for everyone, but many people find certain foods worsen flares while others are better tolerated. Working with a gastroenterologist and registered dietitian helps identify personal triggers and maintain nutrition — especially during active disease. Digestive specialists | education Digestive specialists Ulcerative Colitis Symptoms: Signs to Know Ulcerative colitis hallmark symptoms are frequent loose stools — often containing blood or mucus — along with urgency, cramping, and rectal pain. Severity ranges from a few loose stools daily to more than six bloody stools with fever and fatigue. A gastroenterologist confirms diagnosis and starts treatment. Digestive specialists | seek-care Digestive specialists Upper Endoscopy (EGD): What to Expect An upper endoscopy (EGD) uses a thin flexible camera to examine the esophagus, stomach, and first part of the small intestine. Most patients receive IV sedation and have no memory of the procedure. Recovery is same-day, with a normal diet usually possible within a few hours. The procedure carries a low rate of serious complications. Digestive specialists | education Digestive specialists What Is IBS and How Is It Treated? Irritable bowel syndrome (IBS) causes abdominal pain, bloating, and bowel habit changes without visible intestinal damage. Treatment is individualized — dietary changes, stress management, and medications vary by subtype (IBS-C or IBS-D). It is not dangerous but can significantly affect quality of life. Digestive specialists | education Digestive specialists What Stool Changes Mean for Your Health Most short-lived changes in stool color or consistency are benign — often caused by diet, medications, or hydration. Black or red stool, pale or clay-colored stool, and any persistent change lasting more than two weeks are the findings most likely to need clinical evaluation. Digestive specialists | education Digestive specialists What to Expect During a Colonoscopy A colonoscopy is a 20-to-45-minute outpatient procedure in which a gastroenterologist uses a flexible camera to examine the entire colon. Patients are sedated and comfortable — most have no memory of the procedure. The prep the day before is typically the hardest part. Most people return to normal activity by the next morning. Digestive specialists | education Digestive specialists When to See a Gastroenterologist: 10 Clear Signs See a gastroenterologist when you have rectal bleeding, unexplained weight loss, difficulty swallowing, persistent digestive symptoms, or a family history of colon cancer or inflammatory bowel disease.
