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.
It can also result from medicines or other conditions or diseases. When you have diabetes, low blood sugar can be caused by too much insulin or other diabetes medicine. If you are using insulin, it may happen because: 1  You have accidentally used too much or the wrong type of insulin. 2  Your insulin is no longer good because it has expired or was not stored properly.
