Diabetes is a disease in which blood glucose levels are above normal. Most of
food we eat is turned into glucose (sugar) for our bodies to burn to create energy. The pancreas, an organ that lies near
stomach, produces a hormone called insulin to help glucose get into
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 large amounts of sugar to build up in your blood.
The actual cause of diabetes continues to be a mystery, although both genetics and environmental factors such as obesity appear to play major roles. Diabetes can cause serious health complications including heart disease, blindness, kidney failure, and lower-extremity amputations. According to
Center for Disease Control, diabetes is
sixth leading cause of death in
United States. As of 2002, 18.2 million people in
U.S.--6.3 percent of
population--had diabetes, with 1.3 million new cases being diagnosed each year. The National Institutes of Health also estimate that an additional 5.2 million people have diabetes without actually being aware of it.
There are two main types of diabetes. Type 1 diabetes, which was previously called insulin-dependent diabetes or juvenile-onset diabetes, accounts for about 10% of all diagnosed cases of diabetes. Type 2 diabetes, which was called non-insulin-dependent or adult-onset diabetes, accounts for
remaining 90%. Gestational diabetes is a type of diabetes that only pregnant women get. If not treated, it can cause problems for both
baby and
mother. Gestational diabetes develops in 2% to 5% of all pregnancies, but usually disappears when
pregnancy is over.
Diabetes is a serious disease and phrases such as "a touch of diabetes" or "your blood sugar is a little high" tend to dismiss
fact that diabetes is a major killer of Americans. In addition to
lives that are lost, diabetes has a tremendous economic impact in
United States. The National Diabetes Education Program estimates
cost of diabetes in 2002 was $132 billion. Of this amount, $92 billion was due to direct medical costs and $40 billion due to indirect costs such as lost workdays, restricted activity, and disability due to diabetes. The average medical expenditure for a person with diabetes was $13,243, or 5.2 times greater than
cost for a person without diabetes. In addition, 11 percent of national health care expenditures went to diabetes care.
