Hypoglycemia is a condition that occurs when blood sugars fall to excessively low ranges (usually less than 60mg/dl). With hypoglycemia, patients experience confusion, sweating, shakiness, and in severe cases, coma and seizure. Exercise can induce hypoglycemia, particularly in patients who are taking insulin, although patients on oral agents are also at risk. In part, this decrease in blood sugar results from an increase in the muscles' use of glucose and because the liver's production of glucose is impaired.
