All of the following are causes of fasting hypoglycemia, except:: (A) Glucagon Excess, (B) Glucose-6-Phosphatase deficiency, (C) Glycogen-synthase deficiency, (D) Uremia
Answer is A. In the above question glucagon excess is the answer because glucagon deficiency leads to fasting hypoglycaemia. Also in glucose - 6 - phosphatase deficiency, hypoglycaemia and lactic acidosis can develop after a sho fast. Glycogen synthase deficiency can also lead to hypoglycaemia and ketosis and Response to insulin and glucose utilization is impaired in patients having uremia.
