What is the recurrence risk for diabetes with one affected first-degree relative?

The recurrence risk for developing diabetes when there is one affected first-degree relative typically falls within the range of 5-10%. This percentage is based on genetic and environmental factors that influence the likelihood of developing type 2 diabetes. First-degree relatives, which include parents and siblings, share a significant amount of genetic material and are subject to similar environmental risks, including lifestyle and dietary habits, that contribute to the development of diabetes.

Epidemiological studies have shown that the risk increases in individuals who have a first-degree relative with diabetes compared to those without any family history of the condition. The 5-10% risk reflects the average statistical chance of developing the disease among individuals in this group, highlighting the significant influence of genetic predisposition.

In contrast, the other ranges mentioned in the options are higher than what is typically supported by the current understanding of diabetes recurrence risks among first-degree relatives. This data illustrates the importance of considering both genetics and lifestyle in evaluating the risk of diabetes and helps clarify the expectations for individuals with an affected family member.
