Coeliac Disease
Coeliac disease is an immune reaction to gluten (a protein in wheat, barley and rye) that damages the lining of the small intestine, so nutrients are not absorbed properly.
Causes & risk factors
- An immune reaction to gluten in genetically prone people
- Family history of coeliac disease
- Linked with type 1 diabetes and thyroid disease
- Can appear at any age, sometimes after a trigger like infection or pregnancy
Common symptoms
Tests & diagnosis
Treatment & management
- A strict, lifelong gluten-free diet — the only effective treatment
- Avoid wheat, barley and rye; read food labels carefully
- Correct any deficiencies — iron, calcium, vitamin D, B12
- Dietitian support to plan balanced gluten-free meals
- Regular follow-up to check the gut has healed
When to see a doctor urgently
- Long-standing diarrhoea, bloating or weight loss
- Unexplained iron-deficiency anaemia
- A family member diagnosed with coeliac disease
- Symptoms continuing despite a gluten-free diet

Frequently asked questions
Is coeliac disease the same as gluten intolerance?
No. Coeliac disease is an immune condition that damages the gut; non-coeliac gluten sensitivity causes symptoms without that damage. Get tested before cutting out gluten, or the test can be falsely normal.
Can I eat a little gluten if I feel fine?
No. Even small amounts keep the gut inflamed and raise the risk of complications, even without obvious symptoms. The diet must be strict.
