Foods That Cause Indigestion and Gas

Indigestion can feel like upper-abdominal discomfort, fullness, nausea, or early satiety. Gas may come from swallowed air or fermentation of carbohydrates in the bowel. Rich meals can slow stomach emptying, while legumes and some vegetables may ferment more readily. Acid reflux, gastritis, gallstones, Helicobacter pylori infection, hiatus hernia, or a peptic ulcer can cause similar digestive complaints, so persistent symptoms should not be blamed on food alone.

Keep meals modest and eat at a relaxed pace. Note ingredients, preparation method, portion, and symptoms in a diary. Test one suspected food at a time, and consider whether fried or heavily spiced versions are the issue rather than the ingredient itself. Drink water, limit fizzy drinks, and maintain a varied diet. A clinician can help if symptoms continue or you need to avoid several foods.

Arrange medical review for symptoms that persist, recur without a clear food link, or interfere with eating. Prompt care is needed for severe or localised pain, repeated vomiting, yellowing of the skin, black stools, blood in vomit, difficulty swallowing, or unexplained weight loss. Chest pressure with breathlessness needs urgent help.

Ask whether your symptoms need testing, whether a medicine or infection could be contributing, and how to keep meals balanced during a food trial.
