The effect of the glycemic index on the body gave birth to some very popular low-carb diets such as The South Beach Diet and other diets that monitored carbohydrate ratings. The effect of the glycemic index on the body can assist a person who is watching his or her carbohydrates, either due to diabetes or a diet, to determine which carbohydrates are more dangerous for their body than others. 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. Because the glucose concentration is raised beyond the allowed threshold, glucose remains in the urine, causes more pressure and more frequent urination. When uncontrolled, diabetes can cause kidney edamage. Some patients with Type I diabetes present with nausea, abdominal pain and an comatose state. The glucose stays in the blood and in the urine causing the diabetic to frequently urinate, experience thirst and hunger more than the average person and sweat profusely. After a while, this takes its toll on the system of a diabetic. The kidneys begin to hurt because they are not functioning properly. The condition of high blood glucose is called glycemia. It can cause many complications in an individual including those that affect the kidneys, heart, blood, eyes, and even the central nervous system. People do not die from diabetes. They die from complications caused by the disease that is often allowed to get out of control. Gestational diabetes is a condition in which a woman who has never had diabetes develops high blood glucose levels while pregnant, usually within the later term of the pregnancy. It is estimated that there are about 135,000 cases of gestational diabetes every year in the United States. In most cases, women who develop gestational diabetes will not develop Type II diabetes.
