Erosive Esophagitis and What the LA Grade Means

Save

A report comes back with a letter on it and no explanation. LA stands for Los Angeles — the system is named after a city, not after anything about your esophagus. The grade is a shorthand endoscopists use so that two doctors describing the same esophagus write down the same thing. Here is what the finding means, what it changes about your medication, and what it does not tell you.

What erosive esophagitis means on your report

Erosive means the endoscopist saw breaks in the surface of the esophageal lining — places where the top layer is worn through, rather than merely looking inflamed. That is a different observation from redness, and it is written down differently, because it carries a different consequence: erosive esophagitis is one of the conditions gastroenterology guidance treats as a reason to keep acid suppression going rather than stop it 1.

Erosive esophagitis is a finding, not a feeling — it is what an endoscopist saw through a camera, recorded in the language endoscopists use with each other.

The reason this particular finding carries weight is that it is unusually objective. Much of what a scope reports is a judgment call about shades of pink. A break in the lining is closer to a yes-or-no. Either the surface is intact or it is not, and two endoscopists looking at the same picture will usually agree. Findings that survive that test are the ones guidelines can safely hang decisions on.

What the LA grade describes

The letter records extent. An endoscopist grading by the Los Angeles classification is describing two things about the breaks in front of them: how far each one runs along the esophagus, and how much of the tube's circumference the breaks wrap around. Grade A sits at the limited end of that range and grade D at the extensive end, with B and C between them.

The exact measurement thresholds that separate one letter from the next are technical rules the endoscopist applied at the scope, with your esophagus on the screen and a reference in hand. What lands on your report is the conclusion of that measurement, not the working. If you want to know why yours came out as the letter it did, the person who can answer that is the person who wrote it.

What the letter is not. It is not a pain score, and it is not a prognosis. The grade answers one question — how much of the lining was broken — and stays silent on the rest. That silence is not evasion. It is the sound of a descriptive system doing only the job it was built for, which is why a separate list of GI alarm features exists and is worth knowing regardless of what letter is on your report.

Erosive esophagitis and non-erosive reflux disease are different findings

Having a letter at all is what puts you in the erosive category. A report from someone with the same burning symptoms that finds no breaks in the lining describes something else — non-erosive reflux disease, which is the name for reflux symptoms without visible erosions. The endoscopy is what separates the two. The symptoms, on their own, do not.

That is worth sitting with for a moment, because it runs against intuition. The reasonable assumption is that worse burning means worse damage, and that a normal-looking esophagus means mild disease. The two categories exist as separate names precisely because how a person feels and how their esophagus looks are two different measurements of two different things.

Erosive esophagitis is also not the only thing that inflames an esophagus. Telling eosinophilic esophagitis from ordinary reflux is a separate question with a separate answer, and it is one of the reasons an endoscopist may take tissue samples even when the view already explains the symptoms.

Why the finding changes the conversation about stopping a PPI

For many people on long-term acid suppression, current gastroenterology advice is to attempt to stop or step down, because a great many prescriptions outlive the reason they were written. Erosive esophagitis is one of the named exceptions. Alongside Barrett's esophagus and a bleeding-risk indication, it is a case where the AGA's advice is that the medicine should continue rather than be withdrawn 1.

This matters because the deprescribing conversation is loud right now, and it is mostly a good one. Someone who reads about the risks of long-term proton pump inhibitors and decides to stop is doing something reasonable — for most people, on most prescriptions. But the same guidance that says try stopping also draws a line around a small number of people, and a report with an LA grade on it puts you inside that line 1.

Guidance that says most people should try coming off a PPI, and guidance that says people with erosive esophagitis should stay on one, are the same guidance. They are not in conflict.

None of that is a decision this page can make. It is a reason to raise the report specifically — not reflux in general — with whoever prescribes for you, before changing anything.

How firm is that advice?

Worth knowing what kind of document that advice comes from, because not all guidance is the same weight. The AGA piece is an expert review: specialists reading the literature and reaching a consensus. It is not a formally graded recommendation with a certainty rating printed beside each statement, and the difference is not a technicality.

Formal evidence systems keep two questions deliberately apart. The first is how certain the evidence is — rated high, moderate, low, or very low. The second is how strong the resulting recommendation is — strong or weak — which depends on the balance of benefits and harms, on what people value, and on cost 2. A strong recommendation can rest on low-certainty evidence when the harms of getting it wrong are lopsided. A weak recommendation can rest on excellent evidence when the trade-off is genuinely a matter of preference.

Why this belongs on a page about a letter on a report: it tells you what kind of question to ask. "Is this settled?" and "is this our best current read?" have different answers, and expert-consensus advice is usually the second. That is not a reason to discount it. It is a reason to treat it as a considered position rather than a physical law.

Esophagitis is not gastritis, and the difference is location

These two words get swapped constantly, including by people who have been handed both at different times, and they name different organs. Esophagitis is inflammation of the esophagus, the tube. Gastritis is inflammation of the stomach lining, further down. A report can say one, the other, or both, and they are not interchangeable findings.

The causes diverge too. The NIDDK names H. pylori infection as the most common cause of gastritis, alongside reactive gastropathy from NSAIDs or alcohol, autoimmune gastritis, and stress-related erosive gastropathy 3. That list is a stomach list. It is not the explanation for breaks in an esophagus.

One detail causes real confusion here: the word erosive shows up in both vocabularies. Stress-related erosive gastropathy is a stomach finding with its own causes and its own management 3. Erosive esophagitis is an esophagus finding. Sharing an adjective does not make them relatives, and if your report carries one of them, the other is not automatically implied.

Questions worth asking about your own report

A report written for a referring clinician is not written for you, and the gap is not your fault. The AHRQ's approach to this is called health literacy universal precautions: rather than guessing which patients will struggle with medical language, structure every explanation so that anyone can follow it, using plain language and confirming understanding rather than assuming it 4.

One technique from that toolkit is worth borrowing in the other direction. Teach-back normally means a clinician asking you to say back what you understood, so that gaps surface while there is still time to fix them 4. Used in reverse, it is a fair thing to ask for: can I tell you what I think this says, and you tell me where I have it wrong?

A question that reliably works better than "is this bad?" is "what would have to be different on this report for the plan to change?"

Things the report itself will not tell you, which are worth asking about directly:

  • Which letter was recorded, and whether the endoscopist noted anything beyond the breaks themselves
  • Whether tissue samples were taken, and if so, what question they were meant to answer
  • What the plan is for the medication, given that this finding sits in the group guidance carves out 1
  • What, specifically, should prompt a call back before the next scheduled appointment

Write the answers down while you are still in the room. Almost nobody remembers them afterward, and a report you cannot read is not a report you can act on.

Common questions

Los Angeles. The classification is named for the city where the system was agreed among endoscopists, and the name carries no meaning about your esophagus. It is simply the label that stuck, the way many medical classifications are named after the place or the person that produced them rather than after anything they describe.

Grade A sits at the limited end of the range the system describes, meaning the breaks seen were the least extensive of the four categories. What that means for you is a separate question, and it depends on your symptoms, your history, and what else the endoscopist saw. The letter ranks extent. It does not rank how much the finding matters in your case.

That is a question for the person who prescribes it, and the report is the reason to ask them specifically rather than to decide alone. Current guidance encourages many people to try stopping or stepping down, but names erosive esophagitis as one of the conditions where the medicine should continue instead. Your report puts you inside that carve-out.

No. Esophagitis is inflammation of the esophagus, the tube that carries food down. Gastritis is inflammation of the stomach lining below it. They have different causes — H. pylori infection is the most common cause of gastritis, and it is not what erodes an esophagus. The word erosive appears in both vocabularies, which is where most of the confusion comes from.

The endoscopy report is written first for other clinicians, in their shorthand, and the letter is part of that shorthand. It is entirely normal for a conversation to skip it and go straight to the plan. If you want to know which letter was recorded and why, asking for it is reasonable, and the answer is already written down.

The letter and the symptoms are two different measurements. The grade records how much of the lining showed visible breaks when the camera was there. It is not a record of how you feel, and the two categories in this field — erosive and non-erosive — exist as separate names precisely because appearance and experience do not reliably track each other.

When an esophagus problem stops being a scheduling question

  • Vomiting blood, or vomiting material that looks like coffee grounds
  • Black, tarry stools, which can mean blood from higher up in the digestive tract
  • Food that sticks on the way down, or a sense that swallowing is getting harder over weeks
  • Unintentional weight loss alongside swallowing or reflux symptoms

Vomiting blood or coffee-ground material, or passing black tarry stools, is an emergency-department problem now, not a next-available-appointment problem. Call 911 if you also feel faint, sweaty, or short of breath.

This page explains what an endoscopy report is describing. It is not a reading of your report, and it is not medical advice. Decisions about your medication belong to you and the clinician who prescribed it.
