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.
The most common cause of low blood sugar is too much of a blood sugar lowering medication; or a change in the circumstances surrounding the use of the medication. If you take too much insulin, you will go low. If you take the right amount of insulin and then eat less than you planned, you will go low.
