Weight Loss (Home) > Weight Loss Surgery > Obesity Measured How is Obesity Measured Before Weight Loss Surgery?Before performing weight loss surgery, surgeon examines fitness of patient, if the patient qualifies for surgery or not. A person qualifies for surgery only, if, he /she has a body mass index of 40 or higher or weigh more than 100 pounds over ideal body weight. An individual who is 80 pounds overweight is considered for surgery, if he / she has some health related issues that links with obesity. The body mass index is used to determine the risk of obesity. In measuring the body mass index, the weight of a person is measured in kilogram, height is measured in meter and then the weight in kilogram is divided by the square of the height in meter. The same can also be measured using pounds and inches standards. The body mass index is acceptable and used as a correlation to the degree of obesity. It is very much important for a surgeon to assess each potential surgery patient individually, because measuring obesity is subjective. For example when calculating the body mass index or ideal body weight, muscle mass is not taken into consideration. An individual who is muscular may rate high on the body mass index, without being actually overweight. The patients who are overweight and suffering with sickness like; hypertension, sleep apnea, type 2 diabetes or high blood pressure can be taken into account for weight loss surgery. In 1998, the National Institute of Health, USA has sets standards to measure obesity. These standards help overweight patients and health care professionals in exactly determining whether they are overweight or not. The ideal mass index rating is considered as 19 - 25 for those persons’ who has average body weight and average height. An individual who is much taller can weigh more, but not be over weight. That is why, health care professionals require some standard to fix whether an individual is actually overweight or not. The individuals who have body mass index of 25 to 29.9 are considered as overweight. A body mass index of 30 to 34.9 suggests a person as obese and 35 to 39.9 as severely obese. A body mass index of 40 or more is an indication of morbid obesity. Waist Circumference Test is another common test to measure obesity. Health care professionals use this test in conjugation with other measurements and methods. Along with body mass index chart, waist circumference test helps in a great way in determining, whether an individual is actually overweight or not. A woman with a waist greater than 35 and a man with a waist greater than 40 is considered as obese. Health care professionals often use combine methods to measure obesity.
