Quick answer
What is Coeliac disease?
Coeliac disease is an autoimmune condition, not simply an allergy or intolerance, in which eating gluten (a protein in wheat, barley and rye) triggers the immune system to damage the lining of the small intestine. This impairs absorption of nutrients and can cause diarrhoea, bloating, wind, abdominal pain, tiredness, weight loss and anaemia — though some people have few gut symptoms.
- How it is treated: The only effective treatment is a strict, lifelong gluten-free diet, which allows the gut lining to heal and symptoms to settle.
- Self-care: A strict gluten-free diet is the core of management.
- When to seek help: See a GP for persistent digestive symptoms, unexplained tiredness or anaemia.
What it is
Coeliac disease is an autoimmune condition, not simply an allergy or intolerance, in which eating gluten (a protein in wheat, barley and rye) triggers the immune system to damage the lining of the small intestine. This impairs absorption of nutrients and can cause diarrhoea, bloating, wind, abdominal pain, tiredness, weight loss and anaemia — though some people have few gut symptoms. Untreated, it can lead to nutrient deficiencies and weakened bones. Diagnosis involves blood tests for specific antibodies (while still eating gluten) usually confirmed by a biopsy taken during an endoscopy.
How it is treated
The only effective treatment is a strict, lifelong gluten-free diet, which allows the gut lining to heal and symptoms to settle. This means avoiding wheat, barley and rye and being alert to hidden sources and cross-contamination. Support from a registered dietitian helps make the diet nutritionally complete and practical. People are monitored for nutrient deficiencies (such as iron, folate, vitamin D and calcium) and bone health, and close relatives may be tested as the condition runs in families.

Beyond medication
Lifestyle and self-care
A strict gluten-free diet is the core of management. Reading labels, choosing naturally gluten-free foods, and avoiding cross-contamination are key. A dietitian can help ensure the diet remains balanced and provides enough fibre and nutrients.
When to get help
When to see a doctor
See a GP for persistent digestive symptoms, unexplained tiredness or anaemia. Importantly, do not start a gluten-free diet before testing, as this can make the diagnosis unreliable.
Not sure how urgent it is? It is always OK to call NHS 111 for advice, day or night.
Answers
Coeliac disease: frequently asked questions
Is coeliac disease the same as a gluten intolerance?
No. Coeliac disease is an autoimmune condition in which gluten damages the gut lining, not simply an intolerance. It needs proper diagnosis and a strict lifelong gluten-free diet.
Should I go gluten-free before being tested?
No. You need to be eating gluten for the blood tests and biopsy to be accurate. See a GP first, before changing your diet.
