A very rare complication of type 1 diabetes: insulin edema developed in a newly diagnosed type 1 diabetes

Edema caused by insulin therapy is a rare complication. Here we report a 13 year old boy with newly diagnosed type 1 diabetes who developed edema in lower extremities in the third day of insulin therapy. After exclusion of other causes leading to edema, we diagnosed insulin edema which has been very rarely reported in children. Within 7 days of insulin therapy, edema resolved spontaneously. In newly diagnosed type 1 diabetic children and adolescents insulin-induced edema should be considered after the initiation of insulin therapy. (Turk Arch Ped 2013; 48: 62-4)
