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.

What are gallstones, and who gets them?

Gallstones are hardened deposits that form in the gallbladder — a small, pear-shaped pouch beneath the liver that stores bile. Most are made primarily of cholesterol (roughly 75% of gallstones in Western populations); a smaller proportion are pigment stones made from bilirubin.

Gallstones affect approximately 10–15% of U.S. adults — about 25 million people. Several factors raise the risk 12:

  • Female sex, particularly with multiple pregnancies
  • Obesity or rapid weight loss
  • Age (risk increases from middle age onward)
  • A diet high in refined carbohydrates and low in fiber
  • Family history of gallstones
  • Certain medical conditions (type 2 diabetes, Crohn's disease, blood disorders)
  • Some medications, including certain cholesterol drugs and hormone therapy

What does a gallstone attack feel like?

The medical term for a gallstone attack is biliary colic. It happens when a stone temporarily blocks the cystic duct (the outlet of the gallbladder) as the gallbladder contracts — most often triggered by eating.

Typical features of biliary colic:

  • Location: Upper right abdomen or the center (epigastric) area; sometimes felt in the right shoulder blade or upper back
  • Character: Steady or crampy, intense, building to a peak over 15–30 minutes
  • Duration: Usually 30 minutes to a few hours, then eases as the stone moves back or passes
  • Triggers: Fatty or rich meals, but can occur at any time, including at night
  • Associated symptoms: Nausea, vomiting, bloating, and belching

Not every upper abdominal pain is a gallstone — acid reflux, ulcers, and muscle strain feel similar. An ultrasound is the most common first test to confirm gallstones 1.

Can gallstones cause symptoms that feel like heartburn or indigestion?

Yes, and this is a common source of confusion. Some people with gallstones describe a sensation of bloating, fullness, or discomfort after meals rather than sharp pain. These vague digestive complaints can overlap with acid reflux (GERD), irritable bowel syndrome, and other conditions.

A key distinguishing feature of gallstone pain is its location (upper right side or center rather than lower abdomen) and its relation to fatty meals. However, only a clinician with imaging can tell you definitively what is causing your symptoms 12.

When do gallstones become an emergency?

Most gallstone attacks settle on their own, but several complications require prompt or emergency care:

  • Acute cholecystitis: If the gallbladder becomes inflamed and the pain does not ease within 4–6 hours, worsens, or is accompanied by fever, this is an emergency requiring hospital evaluation
  • Choledocholithiasis: A stone that passes into the common bile duct can cause jaundice (yellowing of skin or eyes), dark urine, and pale stools
  • Gallstone pancreatitis: Stone migration triggering pancreatic inflammation causes severe pain radiating to the back
  • Cholangitis: Infected bile duct — fever, jaundice, and severe abdominal pain together (Charcot's triad) is a medical emergency

These complications need emergency evaluation 12.

How are gallstones diagnosed?

Your clinician will likely recommend:

  • Abdominal ultrasound: The first-line imaging test. It is safe, non-invasive, and highly accurate at detecting gallstones 1
  • Blood tests: Liver enzymes, bilirubin, and inflammatory markers help assess whether complications are present
  • Further imaging (CT or MRCP): Used when the ultrasound is inconclusive or when ductal stones are suspected 2

A gastroenterologist is the right specialist to evaluate gallstone symptoms, interpret imaging, and discuss whether watchful waiting or cholecystectomy (gallbladder removal) is the right next step. Gale can help you find a clinician and prepare for that appointment.

Common questions

Can I have gallstones without any pain?

Yes. The majority of people with gallstones never develop symptoms and may go their entire lives without knowing they have them. These are called silent or asymptomatic gallstones, and they generally do not require treatment.

How long does a gallbladder attack last?

Biliary colic typically peaks within 30 minutes to an hour and resolves within 1–5 hours as the stone shifts. If the pain continues beyond 6 hours or is accompanied by fever, you need urgent medical evaluation for possible acute cholecystitis.

Can diet changes prevent gallstone attacks?

Eating lower-fat meals can reduce the frequency of gallbladder contractions and may lessen the chance of triggering an attack, but dietary changes alone will not dissolve existing gallstones or eliminate the underlying risk. Talk to a gastroenterologist about the full range of options.

Is gallbladder pain always on the right side?

Usually yes — the upper right abdomen is classic — but some people feel it centrally (epigastric area), and referred pain to the right shoulder or upper back is common. Location alone is not a reliable diagnosis; imaging is needed.

Gallstone complications — get emergency care for these signs

  • —Severe upper abdominal pain lasting more than 6 hours without relief
  • —Fever (above 38 °C / 101 °F) with abdominal pain
  • —Yellowing of skin or eyes (jaundice)
  • —Dark tea-colored urine with pale or clay-colored stools
  • —Chills and shaking with upper abdominal pain (possible cholangitis — call 911)

Fever plus jaundice plus severe abdominal pain is a potential biliary emergency. Go to the emergency department immediately or call 911.

This article provides general health information and is not a substitute for clinical evaluation. Upper abdominal pain has many causes; a clinician with appropriate imaging is needed to diagnose gallstones.
