Calculating the body mass index is a fairly accurate way to assess whether the patient's weight is normal, or how pronounced obesity is.
Formula

where: m - body weight in kilograms; h - height in meters; measured in kg/m .

Additional data
The body mass index should be used with caution, solely for an approximate assessment - for example, an attempt to evaluate the physique of professional athletes with its help may give an incorrect result (a high index value in this case is explained by developed musculature). Therefore, for a more accurate assessment of the degree of fat accumulation, along with the body mass index, it is also advisable to determine the indices of central obesity.
The body mass index indicator was developed by the Belgian sociologist and statistician Adolphe Quetelet in 1869.
