Information for Patients

Diabetes Type 2

Also called: Type 2 Diabetes

Diabetes means your blood glucose, or blood sugar, levels are too high. With type 2 diabetes, the more common type, your body does not make or use insulin well. Insulin is a hormone that helps glucose get into your cells to give them energy. Without insulin, too much glucose stays in your blood. Over time, high blood glucose can lead to serious problems with your heart, eyes, kidneys, nerves, and gums and teeth.

You have a higher risk of type 2 diabetes if you are older, obese, have a family history of diabetes, or do not exercise. Having prediabetes also increases your risk. Prediabetes means that your blood sugar is higher than normal but not high enough to be called diabetes.

The symptoms of type 2 diabetes appear slowly. Some people do not notice symptoms at all. The symptoms can include

  • Being very thirsty
  • Urinating often
  • Feeling very hungry or tired
  • Losing weight without trying
  • Having sores that heal slowly
  • Having blurry eyesight

Blood tests can show if you have diabetes. One type of test, the A1C, can also check on how you are managing your diabetes. Many people can manage their diabetes through healthy eating, physical activity, and blood glucose testing. Some people also need to take diabetes medicines.

Also called: High blood glucose, High blood sugar

Hyperglycemia means high blood sugar or glucose. Glucose comes from the foods you eat. Insulin is a hormone that moves glucose into your cells to give them energy. Hyperglycemia happens when your body doesn't make enough insulin or can't use it the right way.

People with diabetes can get hyperglycemia from not eating the right foods or not taking medicines correctly. Other problems that can raise blood sugar include infections, certain medicines, hormone imbalances, or severe illnesses.
