(BlackDoctor.org) — Diabetes is a group of diseases marked by high levels of blood glucose resulting from defects in insulin production, insulin action, or both.
Diabetes can lead to serious complications and premature death, but people with diabetes can take steps to control the disease and lower the risk of complications.
How many Americans have diabetes and pre-diabetes?
• 5.8 million Americans have diabetes — 8.3 percent of the U.S. population. Of these, 7 million do not know they have the disease.
• In 2010, about 1.9 million people ages 20 or older were diagnosed with diabetes.
• The number of people diagnosed with diabetes has risen from 1.5 million in 1958 to 18.8 million in 2010, an increase of epidemic proportions.
• It is estimated that 79 million adults aged 20 and older have pre-diabetes. Pre-diabetes is a condition where blood glucose levels are higher than normal but not high enough to be called diabetes. Studies have shown that by losing weight and increasing physical activity people can prevent or delay pre-diabetes from progressing to diabetes.
What is the prevalence of diabetes by type?
• Type 1 (previously called insulin-dependent or juvenile-onset) diabetes accounts for approximately 5 percent of all diagnosed cases of diabetes in adults.
• Type 2 (previously called non-insulin-dependent or adult-onset) diabetes accounts for 90 to 95 percent of all diagnosed cases of diabetes in adults. Type 2 diabetes is increasingly being diagnosed in children and adolescents.
• Gestational diabetes occurs in 2 to 10 percent of pregnancies. Women who have had gestational diabetes have a 35 to 60 percent chance of developing diabetes, mostly type 2, in the next 10 to 20 years.
What is the prevalence of diabetes by gender?
• 13.0 million men have diabetes (11.8 percent of all men ages 20 years and older).
• 12.6 million women have diabetes (10.8 percent of all women ages 20 years and older).
