BMI can be a useful tool to measure the excess weight and the grade of obesity that an individual is suffering from. It is calculated as a proportion of the weight and height for a particular individual. Generally, higher the BMI, greater is the percentage of fat in the body and consequently increased risk for various metabolic diseases. The BMI of an individual can also be increased because of increased muscle mass as in bodybuilders and in medical conditions which lead to increased water retention in the body such as hypothyroidism, liver and renal diseases. Other factors such as skinfold thickness measurements, evaluations of diet, physical activity and family history are also taken into account by your bariatric surgeon.
