How does one can qualify for Bariatric Surgery or Weight-loss Surgery?
So the World Health Organization (WHO) came up with the concept of Body Mass Index, which is calculated, By weight in Kilograms divided by height in meter square.
So, body mass index or BMI of more than 40 without any medical illness and more than 35 with two or more of the following illness. Example- Heart disease, Diabetes, Blood Pressure, Osteoarthritis, Sleep Apnea, or Thyroid Disorders.
These BMI criteria have been relaxed in the Asian population to 37.5 without comorbidities and 32.5 with comorbidities. Also, it is being done for life-threatening obesity conditions and where it is proven that weight loss is not possible by any other means. Example- dietary modification and exercise.
Age has also been set as a criterion from 18 to 65 years. Having said that, a child as old as 2 years was operated in India with weight of more than 45 kgs and a proven endocrine issue. So the criteria can be flexible and you need to see a Bariatric Expert to guide you regarding the same.
