Hypoglycemia is the opposite of diabetes and means too little sugar in the blood. Symptoms include fatigue, nervousness, sharp hunger, trembling, sweating, rapid heartbeat, mood swings and more. Hypoglycemia is often correctable by a change in diet or, when caused by a diseased organ (such as the liver or pancreas), by treating that part of the body. Dr. Weller attempts to clear misconceptions about the disorder and discusses how to recognize the symptoms and how a high-protein, low-carbohydrate, low-fat diet may help with weight reduction and control of hypoglycemia symptoms.
