Diabetes is classified into two types. In Type I (gestational) diabetes the body does not produce insulin. In Type II diabetes, either the body does not produce enough insulin or the cells ignore the insulin.
Insulin is vitally important as it is necessary for the body to be able to use sugar as the basic fuel for the cells. Insulin takes the sugar from the blood into the cells. If sugar levels build up too high in the blood over time, high blood pressure levels can result in damage to your eyes, kidneys, nerves, or heart. These are serious complications from uncontrolled diabetes.
Because they are at very high risk for cardiovascular disease, patients with diabetes must work with their doctors to achieve good control not only of their blood sugar levels, but also their blood pressure and blood lipids (cholesterol and triglycerides).
