Pre diabetes is a condition in which the blood glucose levels are higher than normal but not high enough to be considered Type II diabetes. Although pre diabetes is not a full fledged disease, it can also cause complications in the heart and blood circulation if left untreated. 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. In 1981, the Glycemic Index was developed at the University of Toronto that rated those foods diabetics should avoid on a scale system. Some foods were very high on the scale and took a longer time to process in the system, causing more strain on the kidneys and adverse affects on insulin. Other foods were low on the scale and digested at a slower pace. In many cases, a person with Type II diabetes feels generally unwell but cannot figure out what is wrong. Symptoms can mirror the flu or other illnesses. If you are experiencing frequent thirst, excessive urination and a substantially increased appetite, have yourself checked out for diabetes. Fatigue is also a symptom of diabetes and Type I Diabetes may cause loss of weight, despite increased eating. This often results in macrosomia. Macrosomia is simply the clinical name for a fat baby. While some people think a fat baby is the sign of a healthy baby, a child born too fat may have a problem fitting through the birth canal. This can cause shoulder damage and may require a cesarean section birth,. It raises our energy level, keeps us active, improves our mental state, is instrumental in treating depression but is essential when managing diabetes. By exercising, a person with diabetes can not only better control the glucose in their blood as active muscles can better eliminate blood glucose than idle muscles, but exercise is an excellent way to implement weight control in diabetes management. It is absolutely essential that a person with diabetes not only take medication or insulin as directed, but also adhere to a diabetic diet. This means getting familiar with which foods should be avoided and which foods can be eaten sparingly. The Glycemic Index was established in 1981 to rate which carbohydrates are the worst for those with diabetes.
