Coeliac disease

  • Coeliac disease is a lifelong autoimmune disease caused by a reaction to gluten.
  • 1 in 100 people have coeliac disease.
  • Coeliac disease symptoms include diarrhoea, constipation, vomiting, stomach cramps, mouth ulcers, fatigue and anaemia.
  • In undiagnosed, untreated coeliac disease there is a greater risk of complications including anaemia, osteoporosis, neurological conditions such as gluten ataxia and neuropathy, and although rare there's an increased risk of small bowel cancer and intestinal lymphoma.
  • Once diagnosed, coeliac disease is treated by following a gluten free diet for life.
  • Dermatitis herpetiformis is the skin manifestation of coeliac disease.
