Your body turns the food you eat into glucose (sugar), which it uses for energy. But if your body isn't able to use the sugar right away, it can build up in your blood and lead to high blood sugar.
When the amount of sugar in your blood stays too high for too much of the time, you may have diabetes. Diabetes is a disease that can cause serious health problems.
The good news is that lifestyle changes may help you get your blood sugar back to normal and avoid or delay diabetes.
Sugar (glucose) can build up in your blood if you:
Having high blood sugar may not cause any symptoms at all. Or it may make you feel very thirsty or very hungry. You may also urinate more often than usual, have blurry vision, or lose weight without trying.
You can take steps to lower your blood sugar level if you understand what makes it get higher. Your doctor may want you to learn how to test your blood sugar level at home. Then you can see how illness, stress, or different kinds of food or medicine raise or lower your blood sugar level.
Other tests may be needed to see if you have diabetes.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
