Autoimmune conditions are common with an estimated prevalence in the UK of 2.5%. The presence of one condition should always prompt the clinician to look for others if new symptoms arise. Autoimmune polyglandular syndromes are well described. However, it is unusual for two or more autoimmune conditions to present simultaneously. We describe a case of two autoimmune conditions--type 1 diabetes and Graves' disease--being diagnosed for the first time in the same individual at the same visit to the emergency department. We suggest that thyrotoxicosis be added to the list of potential precipitants for diabetic ketoacidosis.
