Natural course of insulin edema

Generalized edema due to water retention is a very rare complication of insulin therapy. It affects mainly patients with newly diagnosed diabetes or patients with chronic hyperglycemia following initiation of insulin therapy. When it occurs, it is treated effectively with diuretics. This case report describes a female patient, who developed severe insulin edema following initiation of insulin. Diuretics were not given due to severe side effects, thus the natural outcome of insulin edema was observed. Edema was gradually replaced by fat tissue with persistent weight gain. Physicians treating diabetic patients should be aware of 'insulin edema' in the differential diagnosis of weight gain in patients treated with insulin. (C)2000, Editrice Kurtis.
