What BMI range is classified as grade 3 obesity?

Grade 3 obesity, also known as severe or morbid obesity, is classified by a Body Mass Index (BMI) of 40.0 and above. This classification indicates a significantly increased risk for various health problems, including type 2 diabetes, hypertension, cardiovascular diseases, and certain types of cancer. The BMI measure is used to assess body weight in relation to height to categorize individuals into classes of obesity.

The classification system for BMI defines several ranges:

• A BMI from 30.0 to 34.9 is classified as obesity (grade 1).
• A BMI from 35.0 to 39.9 is classified as obesity (grade 2).
• A BMI of 40.0 to 49.9 indicates grade 3 obesity, underscoring a critical level of excess body fat.
• A BMI of 50.0 or above has additional considerations but is still classified under severe obesity, often associated with even higher risks.

Thus, the correct answer identifies the range where the health implications are particularly severe, emphasizing the importance of clinical attention and potential intervention for individuals within this BMI category.
