Prediabetes: An Unknown Disease

Only about one in eight people with prediabetes knows they have a problem, a U.S. study found. Lacking awareness, people with the elevated blood sugar levels were also less likely to make lifestyle changes such as getting more exercise or eating less sugary food that might prevent them from becoming diabetic. "People with prediabetes who lose a modest amount of weight and increase their physical activity are less likely to develop diabetes," said lead study author Dr. Anjali Gopalan, a researcher at the Philadelphia VA Medical Center.
