Which specialist treats coeliac disease?

A gastroenterologist is a doctor specialising in the digestive system, including the small intestine where coeliac disease causes an immune reaction to gluten. A GP may begin the assessment and arrange a blood test, then refer you if results or symptoms need specialist review. A dietitian can help you follow a medically appropriate gluten-free diet after the diagnostic plan is clear. Digestive symptoms may include abdominal pain, bloating or diarrhoea, while poor absorption can contribute to fatigue, iron deficiency anaemia or vitamin B12 deficiency.

Book a GP appointment if coeliac disease is suspected or symptoms continue without a clear explanation. Keep eating gluten until your clinician explains the testing plan, because removing it beforehand can affect the assessment. Bring details of symptoms, family history, medicines and any prior test results. Do not start supplements or a restrictive diet as a substitute for diagnosis; your clinician can choose the appropriate tests and referral.

Seek prompt medical advice for persistent vomiting, signs of dehydration, black or bloody stools, severe abdominal pain, fainting or rapidly worsening weakness. Arrange a timely review for ongoing unintentional weight loss, marked fatigue or symptoms that are limiting eating and daily activities. These concerns need assessment even if coeliac disease has not yet been confirmed.

Ask whether your symptoms warrant coeliac testing, whether you should continue eating gluten before a blood test, and when a gastroenterology referral is needed. Ask how iron or vitamin deficiencies will be checked and when a dietitian should join your care.
