Diabetes is a complex condition with several types and no clear cause.
If there is a history of a type of diabetes in a person’s family, they may have a higher risk of developing the same condition.
Genetic factors can make some people more vulnerable to some types of diabetes. However, a person may not inherit the condition, and there may be ways to reduce the risk.
Also, an awareness of family history may help with getting an early diagnosis. This, in turn, may help a person prevent some complications.
The role of genetic factors varies among types of diabetes. In type 2, for example, lifestyle factors appear to be more influential than genetics.
Knowing how genes, lifestyle, and the environment affect diabetes can encourage a person to minimize their risk of developing the condition and its complications.
People with a family history of type 2 diabetes, or with risk factors such as obesity, should maintain a healthful diet and a healthy weight.
