Diabetes is a disease in which blood glucose levels are above normal. Most of the food we eat is turned into glucose, or sugar, for our bodies to use for energy. The pancreas, an organ that lies near the stomach, makes a hormone called insulin to help glucose get into the cells of our bodies. When you have diabetes, your body either doesn't make enough insulin or can't use its own insulin as well as it should. This causes sugar to build up in your blood.

Anyone aged 45 years or older should consider getting tested for diabetes, especially if you are overweight. If you are younger than 45, but are overweight and have one or more additional risk factors (see below), you should consider testing.

People with blood glucose levels that are higher than normal but not yet in the diabetic range have "pre-diabetes." Doctors sometimes call this condition impaired fasting glucose (IFG) or impaired glucose tolerance (IGT), depending on the test used to diagnose it. Insulin resistance and pre-diabetes usually have no symptoms. You may have one or both conditions for several years without noticing anything. If you have pre-diabetes, you have a higher risk of developing type 2 diabetes.

People who think they might have diabetes must visit a physician for diagnosis. They might have SOME or NONE of the following symptoms: Nausea, vomiting, or stomach pains may accompany some of these symptoms in the abrupt onset of insulin-dependent diabetes, now called type 1 diabetes.

The following information on treatments for diabetes is from the National Diabetes Fact Sheet: National estimates and general information on diabetes in the United States (Centers for Disease Control and Prevention. Atlanta, GA: US Department of Health and Human Services, 1997): Diabetes knowledge, treatment, and prevention strategies advance daily. Treatment is aimed at keeping blood glucose near normal levels at all times. Training in self-management is integral to the treatment of diabetes.

A number of studies have shown that regular physical activity can significantly reduce the risk of developing type 2 diabetes. It also appears to be associated with obesity. Researchers are making progress in identifying the exact genetics and "triggers" that predispose some individuals to develop type 1 diabetes, but prevention, as well as a cure, remains elusive.

In response to the growing health burden of diabetes mellitus (diabetes), the diabetes community has three choices: prevent diabetes; cure diabetes; and take better care of people with diabetes to prevent devastating complications. All three approaches are actively being pursued by the US Department of Health and Human Services. Both the National Institutes of Health (NIH) and the Centers for Disease Control and Prevention (CDC) are involved in prevention activities.

Diabetes mellitus of any kind is a disorder that prevents the body from using food properly. Normally, the body gets its major source of energy from glucose, a simple sugar that comes from foods high in simple carbohydrates (e.g., table sugar or other sweeteners such as honey, molasses, jams, and jellies, soft drinks, and cookies), or from the breakdown of complex carbohydrates like starches (e.g., bread, potatoes, and pasta).

Type 1 diabetes, which was previously called insulin-dependent diabetes mellitus (IDDM) or juvenile-onset diabetes, may account for 5% to 10% of all diagnosed cases of diabetes. Type 2 diabetes, which was previously called non-insulin-dependent diabetes mellitus (NIDDM) or adult-onset diabetes, may account for about 90% to 95% of all diagnosed cases of diabetes. Gestational diabetes is a type of diabetes that only pregnant women get. If not treated, it can cause problems for mothers and babies.
