After a while, this takes its toll on the system of a diabetic. The kidneys begin to hurt because they are not functioning properly. This is one symptom that diabetics often present with when seeking a physician. They also get blood in their urine and, in the worst case scenario, they faint or enter into an episode of semi-consciousness, confusion which can even lead to a diabetic coma. The good news about pre diabetes is that with proper nutrition and the care of a physician, you can avoid being diagnosed with Type II diabetes. The condition can reverse itself, but it does take work on the part of the individual, as well as compliance with the orders directed by your physician.

This concept was developed to help people who wanted to rank carbohydrates based upon how they affected the blood glucose levels.

A person with diabetes should rely on a qualified ophthalmologist who is familiar with this condition.

The only vegetable that a diabetic should avoid is a potato, as it has a high glycemic index. Insulin injections are usually given to the mother to keep the blood glucose levels intact. A woman who is planning on becoming pregnant, however, can avoid the complication of developing gestational diabetes prior to becoming pregnant.
