Having diabetes means you have too much sugar—called glucose—in your blood. If untreated, diabetes can harm the body, particularly the heart and vascular system. In fact, people with diabetes are 2-4 times more likely to have heart disease or suffer a stroke than those who don't have the disease. Experts say this risk is even greater for women with diabetes.
Diabetes can lead to heart attacks, strokes, kidney disease, blindness, dental disease, amputations, and other serious health problems. And the longer you have high levels of blood glucose traveling around your body, the more likely you are to have problems.
