Answer

Causes of hypoglycemia are varied, but it is seen most often in diabetic patients. Hypoglycemia may result from medication changes or overdoses, infection, diet changes, metabolic changes over time, or activity changes; however, no acute cause may be found. Other causes include alimentary problems, idiopathic causes, fasting, insulinoma, endocrine problems, extrapancreatic causes, hepatic disease, post bariatric surgery, and miscellaneous causes.
