Is it true you can be hypoglycemic and not be a diabetic?

Yes and no: . You would need to take a drug that CAUSES hypoglycemia (insulin is the best example, although there is a category of pills that can also do it). There are extremely rare insulin-secreting pancreatic tumors that can cause hypoglycemia (and other even rarer tumors). But metabolically normal people can't get severe hypoglycemia. To your health!
