Type 2 Diabetes

Condition Basics

What is type 2 diabetes?

Type 2 diabetes is a condition in which you have too much sugar (glucose) in your blood. Glucose is a type of sugar produced in your body when carbohydrates and other foods are digested. It provides energy to cells throughout the body.

Normally, blood sugar levels increase after you eat a meal. When blood sugar rises, cells in the pancreas release insulin, which causes the body to absorb sugar from the blood and lowers the blood sugar level to normal.

When you have type 2 diabetes, sugar stays in the blood rather than entering the body's cells to be used for energy. This results in high blood sugar. It happens when your body can't use insulin the right way.

Over time, high blood sugar can harm many parts of the body, such as your eyes, heart, blood vessels, nerves, and kidneys. It can also increase your risk for other health problems (complications).

What causes it?

When your blood sugar stays too high for too long, it causes type 2 diabetes. It happens when your body can't use insulin the right way. Over time, your body cannot make enough insulin.

What are the symptoms?

Some people who have type 2 diabetes may not have any symptoms early on. You may have the disease for many years before you have symptoms of high blood sugar. Symptoms may include feeling very thirsty or hungry, needing to urinate often, losing weight without trying, and having blurry vision.

How is it diagnosed?

If your doctor thinks that you have type 2 diabetes, they will order blood tests that measure the amount of sugar in your blood. Blood glucose tests and other tests are used. Your doctor will also ask you questions about your medical history and do a physical exam.

How is type 2 diabetes treated?

Treatment for type 2 diabetes will change over time. But the focus will be on keeping blood sugar levels in your target range. Daily habits are important, including eating healthy foods and being active. If you smoke, try to quit. You might have to take medicine every day.
