Which specialist treats food intolerance?

Food intolerance describes symptoms after eating a particular food or ingredient without the same immune mechanism as a food allergy. Bloating and diarrhoea may occur, but these symptoms can also have many digestive causes. A GP reviews your diet, symptom timing, bowel pattern, medicines, and relevant medical history. A gastroenterologist can investigate persistent or complicated digestive symptoms. Food Intolerance provides an overview of the condition.

Keep a brief food and symptom diary, recording portions, timing, and bowel changes. Arrange a GP Consultation if symptoms recur, interfere with eating, or lead you to avoid several foods. Do not remove major food groups for a long period without nutritional guidance. Your clinician may discuss Food Intolerance Testing, but the result should be considered alongside your history. Nutrition Counselling can help maintain a balanced diet during an elimination and reintroduction plan.

Seek prompt medical review for persistent diarrhoea, repeated vomiting, blood in the stool, unexplained weight loss, severe abdominal pain, fever, or signs of dehydration. These features need assessment rather than self-directed dietary restriction. Seek emergency help for collapse, severe weakness, or difficulty breathing, because those symptoms may indicate a different urgent problem.

Ask whether your pattern fits intolerance, allergy, or another digestive condition; whether testing is appropriate; which foods can safely remain in your diet; and when a gastroenterology or dietetic referral would help.
