Prior to the discovery of insulin and pills, people with diabetes died of high blood sugars. Since these were discovered, other problems have become more important.
Diabetes when it results in high blood sugar over a period of years can affect almost every organ system of the body. We refer to these effects as the long-term complicationsof diabetes. These include effects on the heart, brain, kidneys, eyes, stomach, bowel, bladder, sexual organs, peripheral nerves, and others. The whole purpose of treating diabetes is to prevent the damaging effects of high sugars on these organs. If this can be done, a person with diabetes will live a longer, healthier and more pleasant life.
