Coeliac disease presenting as severe hypoglycaemia in youth with type 1 diabetes.

ABSTRACT

BACKGROUND: Coeliac disease is an autoimmune disorder classically characterized by gastrointestinal symptoms and poor growth. The disease can be difficult to recognize in patients with Type 1 diabetes mellitus. Some clinicians find treatment of the disease in asymptomatic individuals controversial. CASE REPORTS Two adolescent female patients with Type 1 diabetes experienced recurrent hypoglycaemic seizures. Neither patient reported gastrointestinal symptoms or poor growth. After diagnosis and treatment of coeliac disease, hypoglycaemia resolved. CONCLUSION: These cases illustrate how frequent unexplained severe hypoglycaemia can be an atypical presentation of coeliac disease in youth with Type 1 diabetes. Furthermore, they emphasize the importance of screening and treatment of coeliac disease in asymptomatic patients with Type 1 diabetes. Although controversial, management of coeliac disease in these asymptomatic patients can prevent the vicious cycle of recurrent hypoglycaemia and decrease risk for morbidity and death.
