How do genetic factors cause type 2 diabetes?
Type 2 diabetes is caused by both genetic and environmental factors. To understand whether diabetes is hereditary and the role of genetic factors, please refer to the following issues:
Scientists have linked multiple gene mutations with a higher risk of diabetes. Not everyone who carries a mutated gene gets diabetes. However, many people with diabetes carry one or more of these mutations.
Lifestyle and inheritance from family
It can be difficult to separate lifestyle risk from genetic risk. Lifestyle choices tend to be influenced by family. If parents are sedentary, often their children are also sedentary. Parents with unhealthy eating habits can also influence the next generation.
Is diabetes hereditary? Which gene is involved in type 2 diabetes?
Studies by the American Diabetes Association in twins suggest that type 2 diabetes can be influenced by genetics. However, these studies are complicated by effects of the environment as it also has an impact on the risk of type 2 diabetes.
