Best Answer: Low insulin means that you may have Insulin Deficient Diabetes. Insulin is the chemical that allows blood sugar to pass into the cells. if the insulin is low the sugar cannot pass into the cells, and so it stays in your blood. each time you eat, more and more blood sugar is added to the blood. the result is Diabetes. Causes for low insulin vary.
When the glucose level is high, the beta cells secrete insulin into the blood; when glucose levels are low, secretion of insulin is inhibited. Their neighboring alpha cells, by taking their cues from the beta cells, secrete glucagon into the blood in the opposite manner: increased secretion when blood glucose is low, and decreased secretion when glucose concentrations are high.
