If I have type 2 diabetes, what is the risk my child will develop it?

Type 2 diabetes tends to run in families. You can inherit genes that increase the chances you will develop type 2 diabetes. Studies of twins have shown that genetics play a very strong role in the development of type 2 diabetes. However, scientists do not yet have tests that can predict which genes cause diabetes.

Lifestyle also influences the development of type 2 diabetes. Obesity tends to run in families, and families tend to have similar eating and exercise habits.

If you have a family history of type 2 diabetes, it may be difficult to figure out whether your diabetes is due to lifestyle factors or genetic susceptibility. Most likely it is due to both. However, don’t lose heart. Studies show that it is possible to delay or prevent type 2 diabetes by exercising and losing weight.

Ask your provider to refer you to a medical geneticist or genetic counselor if you have concerns about your baby’s risk for diabetes. They are trained to assess the contributions of genetic and environmental factors in causing many diseases, including diabetes. They will know the results of the latest diabetes and genetics studies and studies to prevent diabetes in high-risk individuals.
