Type I Diabetes differs from Type II in that a person with Type I Diabetes does not produce insulin at all. Insulin is needed to take sugar from the blood into the cells. Type I diabetes used to be called Juvenile Diabetes as it was diagnosed in children at early ages. The symptoms of Type I and Type II Diabetes are very similar. Those with a high rating, take the longest time to break down and do the most damage to the system of someone with diabetes. The good glycemic foods; that is, those with the lower rates, are more desirable not only for diabetics, but for those who are watching their carbohydrate intake through such diets as the South Beach Diet, they should also be aware of what the good glycemic foods are. However, this medication has not done as well as the sulfonlureas, which are considered the best possible medications that treat diabetes at this time. However, for those who are allergic to sulfur, Precose is a good alternate. Other new medications that are concentrating on controlling the glycemic control in the system include Symlin and Byetta. Some of the complications include those with the heart, circulation, blood vessels, kidneys and even eyesight. Because of the high blood glucose levels, a person with diabetes risks having problems with their eyesight. Eye complications of diabetes include those affecting the retina, the vitreous, the lens and the optic nerve. Therefore, those who have pre diabetes can stave off the disease by making some healthy life choices that will eliminate their need for medication or insulin in later years. One way to reverse the effects of pre diabetes is to maintain a healthy weight. This can be easily accomplished through diet and exercise. People who have a first degree relative with diabetes can avoid contacting the illness by having themselves tested by their physician. The physician can do a series of blood tests that will determine whether or not the patient is pre disposed to this condition. If a person has a pre diabetic condition, there are many things they can do to avoid getting this disease.
