Which individual is classified as high risk for type 2 diabetes based on body mass index?

The individual identified as having a body mass index (BMI) of 49 is classified as high risk for type 2 diabetes due to the significant obesity indicated by this measurement. A BMI of 30 or above is categorized as obese, and a BMI of 49 falls well into the category of severe obesity, which is associated with an increased risk of developing insulin resistance, type 2 diabetes, and various other metabolic disorders.

Obesity, particularly when excessive, leads to changes in how the body processes insulin and glucose. Fat tissue, especially visceral fat, can produce inflammatory substances and hormones that disrupt insulin signaling, contributing to the development of type 2 diabetes. Furthermore, severe obesity often coexists with other risk factors like hypertension and dyslipidemia, compounding the health risks.

While the other options reference individuals with potential risk factors, such as family history or age-related concerns, it is the specific and significant degree of obesity in the second option that places that individual at a markedly higher risk for type 2 diabetes. A family history of diabetes, age, or previous illness recovery does not directly equate to the same kind of imminent risk that a very high BMI presents.
