What should you know about random stomach bloating?

Bloating is a feeling of fullness or visible abdominal expansion. It may follow fast eating, fizzy drinks, constipation, or changes in gut bacteria. Food Intolerance and Lactose Intolerance can cause bloating after particular foods. Irritable Bowel Syndrome may link bloating with abdominal pain and changes in bowel habit. Coeliac Disease can affect digestion after gluten exposure. Giardiasis may cause bloating with diarrhoea after contaminated food or water, while Helicobacter Pylori Infection can be associated with upper abdominal discomfort and indigestion. The pattern matters more than one isolated episode.

Eat slowly, chew thoroughly, drink water, and take gentle movement after meals. Keep a diary of foods, portions, bowel movements, pain, diarrhoea, and constipation. Avoid removing many foods at once, because this can make the pattern harder to understand and may reduce nutrition. A clinician or Nutrition Counselling service can help plan a balanced trial when a food trigger is suspected. Treat constipation only with advice suited to your health and medicines.

Arrange a medical review when bloating is persistent, repeatedly returns, steadily worsens, or comes with weight loss, ongoing diarrhoea, constipation, vomiting, blood in the stool, fever, or reduced appetite. Seek urgent help for severe or sudden abdominal pain, a hard swollen abdomen, repeated vomiting, inability to pass stool or gas, fainting, or breathing difficulty. These features need assessment rather than self-treatment.

Does my symptom pattern suggest constipation, intolerance, infection, reflux, or another digestive condition? Do I need testing? How can I investigate food triggers without creating an overly restricted diet?
