Prevention

Currently there is no way to prevent type 1 diabetes, but ongoing studies are exploring ways to prevent diabetes in those who are most likely to get it. People who have a parent, brother, or sister with type 1 diabetes and are willing to participate in one of these studies should talk with their doctors.

Preventing diabetes complications

People who have type 1 diabetes can help prevent or delay the development of complications by keeping their blood sugar in a target range. They also need regular medical checkups to detect early signs of complications. If complications are treated early, the damage may be stopped, slowed, or possibly reversed.

People who have other health problems along with diabetes, such as high blood pressure or high cholesterol, need to treat those conditions. Also, not smoking can reduce the risk of complications. Having other health problems can increase the risk for complications from diabetes.

Preventing disease

Get a flu vaccine every year. When you have the flu, it can be harder to manage your blood sugar. It's a good idea to get a pneumococcal vaccine for pneumonia and a vaccine for hepatitis B.

You may need or want additional immunizations if certain situations raise your chance for exposure to disease.
