Gut Health: the complete guide

Bloating and an unsettled stomach are some of the most common reasons people look up gut health. Often they're linked to everyday things like swallowed air, gas from certain foods, eating quickly or constipation, and sometimes to conditions such as irritable bowel syndrome (IBS). This page brings together our free gut health articles in one place. Start with the main article on everyday bloating, then read by topic: food and fiber (fibre), eating habits, movement, and keeping a simple food and symptom diary. The articles explain what the NIH, the NHS, NICE and clinical guidelines say, and each one links to its sources so you can check them yourself. Everything here is general information, not a diagnosis. Bloating that lasts, or comes with warning signs such as unexplained weight loss, bleeding, or a change in bowel habits, should always be checked by your doctor.

Frequently asked questions

Why am I bloated after eating?

Bloating after eating can have several explanations, and the timing alone does not identify one. Gas, meal habits and individual food tolerance are topics a healthcare provider may explore. Note what you actually notice without assuming a diagnosis or removing many foods. Persistent, new or worrying bloating deserves medical advice.

What foods cause bloating and gas?

Some foods may be associated with gas for some people, but individual experiences differ and there is no universal exclusion list. A simple record can capture what you notice around meals without claiming causation. Discuss persistent discomfort with your healthcare provider before making a restrictive change or assuming a food intolerance.

How to keep a food diary?

Write down meals, approximate times and any observations you want to discuss, using ordinary descriptions rather than diagnostic labels. Keep the format simple enough to use without pressure. A diary records patterns you noticed; it does not prove that a food caused a symptom or replace assessment by your healthcare provider.

Can bloating be serious?

Bloating is common, but common does not mean every episode can be dismissed. New, persistent, worsening or worrying symptoms deserve medical advice, especially alongside other changes. Severe abdominal pain or urgent symptoms require prompt help. An article or diary cannot distinguish routine discomfort from a problem that needs medical assessment.

What are high fiber foods?

Beans, lentils, whole grains, vegetables and fruit are examples of foods that contain fiber. Amounts differ by food and portion, so variety matters more than a single special ingredient. If changes in fiber cause discomfort, discuss a gradual approach with a healthcare provider rather than making large or restrictive changes.

Why does my stomach blow up like a balloon after eating?

That description conveys how uncomfortable bloating can feel, but it does not establish a cause. A meal-by-meal record may provide useful context for a healthcare conversation, not proof of intolerance. If the swelling is new, persistent, severe or accompanied by worrying symptoms, seek medical advice rather than relying on online explanations.
