In short
An upper endoscopy report describes what the lining looked like and what was sampled. Gastritis on a report is a description, not a diagnosis of your symptoms, and the biopsy result usually matters more than the pictures.
Emergency if: After an endoscopy: severe or worsening abdominal or chest pain, vomiting blood, black tarry stools, fever, or difficulty breathing — go to an emergency department now.

What the procedure looks at
An upper gastrointestinal endoscopy passes a flexible tube with a camera through the mouth to examine the oesophagus, the stomach and the first part of the small intestine. The report works down in that order, so the anatomy of the page follows the anatomy of the journey.
Two things happen during it: looking, and sampling. The visual description is available immediately and is often discussed with you before you leave. Biopsy results take several days, and in many cases they, rather than the appearance, decide what happens next.
02
The oesophagus: reflux, rings and Barrett's
Oesophagitis means inflammation of the lining from acid, usually graded by how much of the surface is affected. A hiatus hernia is often noted here — part of the stomach sitting above the diaphragm — and is extremely common, frequently incidental, and by itself not a reason for surgery.
Barrett's oesophagus is the one term worth understanding properly. It means the lining near the stomach has changed to a type resembling intestinal lining, in response to long-standing acid exposure. It is not cancer. It carries a small increased risk of developing cancer over many years, which is why it is entered into a surveillance programme with repeat endoscopies at intervals set by its length and its biopsy findings.
03
The stomach: gastritis, erosions and ulcers
Gastritis on an endoscopy report means the lining looked red or inflamed, and it is reported extremely often. It correlates poorly with how you feel — people with indigestion frequently have a normal-looking stomach, and people with none can have a report describing gastritis. Treat it as one observation among several rather than as the explanation for your symptoms.
Erosions are shallow breaks in the surface. An ulcer is deeper and is described with its site and size, and it always prompts two questions: is Helicobacter pylori present, and are anti-inflammatory painkillers being taken. Stomach ulcers are usually biopsied and often re-examined after treatment to confirm healing, because a small proportion of what looks like an ulcer is not one.
04
Biopsies, and what they are looking for
Biopsies are painless and taken routinely, and their presence on the report does not imply that cancer is suspected. Stomach samples are commonly taken to test for H. pylori. Samples from the first part of the small intestine are the standard way of confirming coeliac disease, and are why you are usually asked to keep eating gluten until after the procedure.
If Barrett's is seen, the biopsies are looking specifically for dysplasia — disordered cells that have not become cancer — because its presence and grade set both the surveillance interval and whether treatment is offered. A report describing Barrett's with no dysplasia is the reassuring version of that finding.
05
Normal reports, and what they rule out
A completely normal endoscopy in someone with long-standing indigestion is a common and genuinely useful result. It makes ulcer, significant inflammation and cancer unlikely, which leaves functional dyspepsia — real symptoms without visible damage — as the usual explanation, and that is managed rather than re-investigated.
Endoscopy does not see everything. It cannot assess the gallbladder, the pancreas, or the small intestine beyond its first part, and it does not measure acid reflux. If symptoms persist despite a normal report, the next test is usually a different test entirely, not a repeat of the same one.
06
After the procedure
A sore throat, bloating and wind for a day are normal. If sedation was used, judgement and reaction times are affected for the rest of the day, so driving, signing anything important and being alone are all deferred until the next day.
Complications are uncommon but specific, and they are worth knowing in advance because they present after you get home. Severe or worsening abdominal or chest pain, vomiting blood, black tarry stools, fever, or difficulty breathing after an endoscopy all need urgent assessment rather than waiting to see how the night goes.
When to act
Routine — see a doctor
A report describing gastritis or a hiatus hernia with no ulcer and no alarm features: discuss treatment and the biopsy result at your follow-up appointment.
Same-day — call promptly
An ulcer on the report that has not been discussed, a pending H. pylori result with ongoing symptoms, or new difficulty swallowing.
Emergency — act now
After an endoscopy: severe or worsening abdominal or chest pain, vomiting blood, black tarry stools, fever, or difficulty breathing — go to an emergency department now.
