What should you know about bloating in stomach medicine?

It may make the abdomen feel tight or look more prominent after meals. Bloating can come and go, or continue alongside discomfort, belching, altered bowel movements, or early fullness.

Gas can build up when you swallow air while eating quickly, chewing gum, drinking through a straw, or talking while eating. Constipation can also leave stool and gas moving slowly through the bowel.

Bloating after particular foods may occur with lactose intolerance or another food intolerance. Persistent bloating with abdominal pain and changes in bowel habits can occur with irritable bowel syndrome. Coeliac disease, giardiasis, and Helicobacter pylori infection are other conditions a clinician may consider when symptoms fit. Bloating alone does not identify one cause.

Keep a simple record of meals, drinks, bowel movements, and symptoms. Eat slowly, choose smaller portions, stay hydrated, and take gentle walks if you feel able. If constipation is present, gradually increasing fibre may help, but a sudden increase can temporarily worsen gas.

Do not remove several food groups without guidance, because this can make meals unnecessarily restrictive. A clinician or nutrition counsellor can help identify patterns and plan balanced changes. Medicines for gas or constipation may be suitable for some people, but ask a pharmacist or doctor if symptoms are frequent, you take other medicines, or you are pregnant.

Arrange a medical review if bloating is new and persistent, keeps returning, interferes with eating or daily activities, or comes with ongoing pain, vomiting, diarrhoea, constipation, weight change, or reduced appetite. A clinician may ask about timing, diet, bowel habits, and medicines before deciding whether tests are needed.

Seek urgent care for severe or rapidly worsening abdominal pain, repeated vomiting, a swollen and hard abdomen, inability to pass stool or gas, blood in vomit or stool, fainting, or trouble breathing. These symptoms can signal a problem needing prompt assessment.

You could ask: What causes best fit my timing and other symptoms? Could constipation, a food intolerance, or a medicine be contributing? Should I keep a food and symptom diary? Do I need testing, and what warning signs should prompt an earlier review?
