Cost is also a consideration in many cases as the insulin must be injected every day and, in certain instances, many people have to inject the insulin several times a day. Another benefit of modern technology in managing people with diabetes through the use of insulin is the insulin pump. This is much more effective than injections as it is a catheter that remains under the skin and separates the insulin into three different types of insulin. 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. We often think of diabetics as being people with a sweet tooth who crave sugar. This is not the case. More often, a person who is obese has more of a chance of getting diabetes than a person who maintains his or her weight. One way how to prevent diabetes is by managing your weight. Although there is little you can do about having a genetic disposition to the disease, there are ways you can prevent becoming one of the millions of Americans who develop diabetes each year. It is a common misconception that someone suffering from hypoglycemia should be given something sweet to alleviate the condition. The truth of the matter is that those suffering from hypoglycemia are usually lacking protein and a food high in protein can alleviate their symptoms. Peanut butter is an excellent choice in helping someone suffering from hypoglycemia. They die from complications caused by the disease that is often allowed to get out of control. Everyone is prone to tooth and gum problems. There are many causes. Heredity plays an important role as does dental hygiene. Smoking also contributes to tooth and gum problems. But the diabetic has more of a chance of developing tooth and gum disease than the average person. Because of this potentially dangerous side effect, sulfonylureas are often given with other drugs, most notably Glucophage, or more commonly known as Metformin. This drug works well with Glucotrol as it reduces the amount of glucose in the liver while the Glucotrol increases the amount of insulin in the pancreas.
