Can father diabetes be inherited from son?

Diabetes can be inherited from fathers to sons.

If a father has diabetes, especially type 2 diabetes, his genes may be passed on to sons. Mutations in certain genes may make an individual more susceptible to diabetes. This means that sons may carry genes in their genetic background that increase the risk of developing diabetes. In addition, diabetes is usually a polygenic disease, not a single gene. This means that genetic factors, even if present, do not necessarily cause a son to develop diabetes, but rather increase the likelihood of the disease. In addition to genetic factors, environmental factors also play a key role in the development of diabetes. For example, unhealthy diet, lack of exercise, obesity, stress, and other environmental factors may make a son more likely to develop diabetes even if he has a genetic susceptibility. If the son can maintain a healthy lifestyle, including a balanced diet, moderate exercise, weight control, etc., the risk of disease can be reduced to some extent.
