Type 2 diabetes is a chronic disease that affects how the body processes blood sugar. An estimated 26 million Americans have diabetes, and 7 million are unaware that they have it. The number of cases has doubled since 1997. While there are some outward symptoms like weight gain, most signs of diabetes are internal as the disease causes blood sugar levels to rise. Lifestyle changes like improved diet and exercise have been shown to help manage the disease and in some cases even cause remission. Regular exercise, especially interval training, can help lower blood sugar levels and reduce health risks. Managing diabetes depends on the individual through diet, medication if needed, and exercise.
