Insulin autoimmune syndrome

Print

Disease Overview

Insulin autoimmune syndrome is a rare condition that causes low blood sugar (hypoglycemia). This occurs because the body begins to make a specific kind of protein called antibodies to attack insulin. Insulin is a naturally occurring hormone that is responsible for keeping blood sugar at a normal level. When blood sugar levels get too high, insulin helps to store the sugar for future use. People affected by insulin autoimmune syndrome have antibodies that attack insulin, causing it to work too hard and the level of blood sugar to become too low. Insulin autoimmune syndrome most often begins during adulthood.[12581][12582]
