There are other rare causes for hypoglycemia, such as insulin-producing tumors (insulinomas) and certain medications.Despite our advances in the treatment of diabetes, hypoglycemic episodes are often the limiting factor in achieving optimal blood sugar control.In large scale studies looking at tight control in both type 1 and type 2 diabetes, low blood sugars occurred more often in the patients who were managed most intensively.here are other rare causes for hypoglycemia, such as insulin-producing tumors (insulinomas) and certain medications. Despite our advances in the treatment of diabetes, hypoglycemic episodes are often the limiting factor in achieving optimal blood sugar control.
