Onset of type 2 diabetes is most typical after which age?

• A. After age 40
• B. Before 20
• C. Between 20 and 30
• D. After 60

Answer: (A)

The main idea here is that type 2 diabetes is most commonly seen in adults as insulin resistance and gradual beta-cell dysfunction accumulate with age. Because risk rises with aging—and with factors like obesity and a sedentary lifestyle—the typical onset occurs after 40 years old. While it can occur later in life (after 60) or, less commonly, at younger ages, the age range most consistently associated with the onset is after 40. Ages before 20 are more commonly linked to other forms of diabetes (like type 1), and the 20–30 range is less typical for type 2.
