Diabetes, Obesity, and the Metabolic Syndrome
Diabetes mellitus (DM) or diabetes, as we usually call it, is a major medical, personal, and public-health problem. Diabetes is a chronic disease associated with abnormally high levels of glucose (sugars) in the blood. A rise in glucose occurs when foods are consumed. Glucose from blood is an energy source for cells and tissues throughout the body. However, utilization of glucose requires a hormone, insulin, that allows the glucose to be used. Diabetes occurs when the body does not make enough insulin or when cells cannot adequately make use of the available insulin. In 2006, the American Diabetes Association (ADA) estimated that 20.8 million people, roughly 7 percent of the US population, had diabetes. Among these, 14.6 million have been diagnosed, and 6.2 million are unaware they have the condition. Another 41 million have “pre-diabetes,” a condition many experts believe leads to diabetes.
The incidence of the disease in the US population varies with age. For those over 60, more...
