This is a term to describe the process in which the body reacts to low blood sugar or a rapid drop in blood sugar. When the body perceives a fast or low drop in glucose, it protects itself by releasing natural glucagons which raise the blood sugar. When this occurs, we call it somogyi or somogyi rebound, and this rebound or high blood glucose can last up to 72 hours. Treatment is to decrease the insulin dosage by 25-50%.
