A NIDDK Overview of Diabetes
What Is the Scope and Impact of Diabetes? continued...
Diabetes is associated with long-term
complications that affect almost every major part of the body. It contributes
to blindness, heart disease, strokes, kidney failure, amputations, and nerve
damage. Uncontrolled diabetes can complicate pregnancy, and birth defects are
more common in babies born to women with diabetes.
Diabetes cost the United States $98 billion
in 1997. Indirect costs, including disability payments, time lost from work,
and premature death, totaled $54 billion; medical costs for diabetes care,
including hospitalizations, medical care, and treatment supplies, totaled $44
Who Gets Diabetes?
Diabetes is not contagious. People cannot
"catch" it from each other. However, certain factors can increase one's
risk of developing diabetes. People who have family members with diabetes
(especially type 2 diabetes ), who are overweight, or who are African American,
Hispanic, or Native American are all at greater risk of developing
Type 1 diabetes occurs equally among males
and females, but is more common in whites than in nonwhites. Data from the
World Health Organization's Multinational Project for Childhood Diabetes
indicate that type 1 diabetes is rare in most Asian, African, and American
Indian populations. On the other hand, some northern European countries,
including Finland and Sweden, have high rates of type 1 diabetes. The reasons
for these differences are not known.
Type 2 diabetes is more common in older
people, especially older women who are overweight, and occurs more often among
African Americans, Hispanics, and American Indians. Compared with non-Hispanic
whites, diabetes rates are about 60 percent higher in African Americans and 110
to 120 percent higher in Mexican Americans and Puerto Ricans. American Indians
have the highest rates of diabetes in the world. Among Pima Indians living in
the United States, for example, half of all adults have type 2 diabetes. The
prevalence of diabetes is likely to increase because older people, Hispanics,
and other minority groups make up the fastest growing segments of the U.S.
How Is Diabetes Managed?
Before the discovery of insulin in 1921, all
people with type 1 diabetes died within a few years after the appearance of the
disease. Although insulin is not considered a cure for diabetes, its discovery
was the first major breakthrough in diabetes treatment.
