Diabetes is classifed in 2 types. In Type 1 diabetes the body does not produce insulin. In Type 2 diabetes, either the body does not product enough insulin or the cells ignore the insulin. Insulin is important as it is necessary for the body to be able to use sugar as the basic fuel for the cells in the body. Insulin takes the sugar from the blood into the cells. If sugar builds up in the meantime, high blood pressure levels can result in damage to your eyes, kidneys, nerves, or heart.
