About this symptom
Bloating is the sensation of fullness, pressure or an enlarged abdomen after eating. It does not always mean excessive intestinal gas or a single gastrointestinal disease. Dietary patterns and bowel habits may contribute.
What this topic means
The complaint can arise with constipation, changes in gut sensitivity, food-related symptoms or gastrointestinal illness. No diagnosis can be established by the sensation alone; persistently changing symptoms deserve attention.
When to seek medical advice
Describe discomfort, gas, abdominal rumbling, constipation or diarrhoea, the timing after meals and any association with particular foods. Progressive swelling, unintended weight loss, blood in stool or repeated vomiting are important warning features.
Options and limitations
Colonoscopy is not automatically indicated for routine bloating. Likewise, eliminating gluten or dairy without a clear reason can complicate later assessment. Testing should follow the clinical history and relevant risk factors.
Assessment and preparation
The clinician reviews stool pattern, pain, diet, medicines, duration and any alarm signs. Physical examination and, if justified, laboratory, stool or imaging tests help distinguish functional symptoms from other conditions.
Treatment, risks and follow-up
The plan may involve regular meals, suitable hydration and activity, treating constipation, and carefully chosen dietary adjustments. The goal is symptom relief while identifying and addressing a confirmed cause when one exists.
When urgent help is needed
Severe sudden abdominal pain, a rigid or markedly distended abdomen, repeated vomiting with inability to pass stool or gas, collapse or substantial bleeding may signal obstruction or another emergency. Call 103 promptly.

Frequently asked questions
Is bloating always caused by excess gas?
No. Gut sensitivity, stool retention and other mechanisms can cause bloating even without unusually high gas volumes.
Does everyone with bloating need colonoscopy?
No. Colonoscopy is chosen based on symptoms, age, risk factors, alarm signs and clinical assessment.
Should I stop eating gluten and dairy on my own?
Not necessarily. Broad restrictions can be unnecessary and may interfere with some tests; discuss a suitable approach with a clinician.

A medical consultation is needed for diagnosis and treatment recommendations.
Self-treatment can be harmful to your health.
