what is the major cause of type 1 diabetes?

What causes type 1 diabetes? Type 1 diabetes occurs when your immune system, the body's system for fighting infection, attacks and destroys the insulin-producing beta cells of the pancreas. Scientists think type 1 diabetes is caused by genes and environmental factors, such as viruses, that might trigger the disease.

Type 1 diabetes is a condition that causes the level of glucose (a type of sugar) in your blood to become too high. It happens when your body is not able to produce enough of a hormone called insulin, which controls blood glucose.

Type 1 diabetes definition In people with type 1 diabetes, cells in the pancreas that make insulin are destroyed, and the body is unable to make insulin. Insulin is a hormone that helps your body's cells use glucose for energy. Your body gets glucose from the food you eat.

Type 1 diabetes puts patients at huge risk for heart disease: Heart attacks and other cardiovascular complications cause the death of nearly 3 out of every 4 people with type 1 diabetes, compared with just 1 in 4 people in the general population.

In type 1 diabetes, there's no insulin to let glucose into the cells, so sugar builds up in your bloodstream. This can cause life-threatening complications.

Viral Trigger for Type 1 Diabetes. The most popular hypothesis circulating within and beyond the scientific community is that viral infections enhance or elicit autoimmune disorders such as type 1 diabetes. Indeed, viruses can injure β-cells and have been isolated in pancreatic tissues from diabetic patients.

T1D Facts. Type 1 diabetes (T1D) is an autoimmune disease that progresses in three stages. In people with T1D, the immune system mistakenly attacks and destroys healthy insulin producing cells, called beta cells. TrialNet is working to change that.

Diabetes occurs when the glucose, or sugar, in the blood is poorly controlled and consistently high. Type 1 occurs when the body does not produce enough of the hormone that allows cells to absorb and use glucose. This hormone is called insulin.

In people with this type of diabetes, scientists have found changes in the genes that produce certain proteins. These proteins play a key role in the immune system. These genetic features make a person susceptible to developing type 1 diabetes, and certain factors can trigger the condition.

Nothing that either a parent or the child did caused the disease. Once a person has type 1 diabetes, it does not go away and requires lifelong treatment. Kids and teens with type 1 diabetes depend on daily insulin injections or an insulin pump to control their blood glucose levels.

The exact cause of type 1 diabetes is unknown. Usually, the body's own immune system — which normally fights harmful bacteria and viruses — mistakenly destroys the insulin-producing (islet, or islets of Langerhans) cells in the pancreas.

Research has shown that Type 1 diabetes is caused by a combination of genetic and environmental factors. If one family member has Type 1 diabetes, there's a slightly increased risk of another family member developing it, too. But, many people diagnosed have no family history of diabetes.

It's not preventable right now, but researchers are working on it. Currently, there is no way to prevent type 1 diabetes. Researchers are still working to fully understand what causes or triggers type 1; without fully understanding that, it's difficult to prevent the disease.
