Type 1 Diabetes in Children

Condition Basics

What is type 1 diabetes?

Type 1 diabetes is a disease that starts when the pancreas stops making enough of a hormone called insulin. Insulin helps the body use sugar from food as energy or store it for later use. If there isn't any insulin, too much sugar stays in the blood. Over time, high blood sugar can harm many parts of the body. These include the eyes, heart, blood vessels, nerves, and kidneys.

Type 1 diabetes can occur at any age, but it usually starts in children or young adults. It's a lifelong disease. But with treatment and a healthy lifestyle, people can live a long and healthy life.

What causes it?

The body makes insulin in beta cells, which are in a part of the pancreas called the islet (say "EYE-let") tissue. Type 1 diabetes starts because the body's immune system destroys those beta cells. So people who have type 1 diabetes can't make their own insulin.

What are the symptoms?

Symptoms of type 1 diabetes include urinating often, being very thirsty, losing weight without trying, being hungrier than usual, and having blurry vision. Symptoms are caused by high blood sugar. They usually develop quickly, over a few days to weeks. At first, symptoms may be overlooked or mistaken for another illness, like the flu.

How is it diagnosed?

The doctor will ask about past health issues and do a physical exam. Blood tests are done to measure how much sugar is in the blood. The doctor will use those blood test results and the American Diabetes Association criteria to diagnose diabetes.

How is type 1 diabetes treated?

Treatment for type 1 diabetes focuses on keeping blood sugar levels within a target range and doing things to reduce complications. Taking insulin, making healthy food choices, and getting regular exercise can help control blood sugar. You'll also need to check blood sugar levels several times a day.
