Digestive health

Peptic ulcer disease

An ulcer is a sore in the stomach or duodenum. Treatment addresses the cause and supports healing.

THE BIG PICTURE

Two common causes of ulcers

H. pylori and certain painkillers are the main causes. An ulcer affects the digestive lining.

Two common causes

H. pylori
NSAID painkillerse.g. ibuprofen
A sore in the stomach or duodenal lining

Spicy food is not the usual cause. Do not stop prescribed aspirin without advice.

Symptoms may include upper abdominal pain, nausea or early fullness, but some ulcers are silent. Tests identify the cause. Food-related pain alone cannot confirm an ulcer.

QUESTIONS YOU MAY HAVE

Let's make it clearer.

Are ulcers caused by spicy food?

Spicy food may worsen discomfort in some people, but H. pylori and NSAID medicines are the main causes. Diet changes alone do not treat them.

Can I stop treatment when the pain settles?

Follow the prescribed duration and review plan. Symptom improvement does not always confirm healing or successful clearance of H. pylori.
