At what age is an individual more likely to develop type 2 diabetes mellitus?

Individuals are more likely to develop type 2 diabetes mellitus at age 40 and older due to a combination of risk factors that tend to accumulate with age. As people age, they often experience changes in body composition, reduced physical activity, and an increase in insulin resistance, all of which contribute to the onset of type 2 diabetes.

Additionally, the prevalence of type 2 diabetes is notably higher in older adults compared to younger populations, mainly due to lifestyle factors, nutritional habits, and the natural decline in glucose metabolism as the body ages. Those under 20 or even in their 20s are at a significantly lower risk, as this age group typically has a healthier metabolism and fewer associated risk factors.

In contrast, while individuals in their 30s can develop type 2 diabetes, it remains less common when compared to individuals over 40, highlighting the increasing risk that comes with advancing age. This information is critical for understanding the demographic trends related to type 2 diabetes and for implementing effective prevention strategies.
