MYTH: Bariatric surgery is the "easy way out."

Bariatric surgery makes life "easy" rather than it being easy way out. Successfully losing weight and keeping it off for long term requires lifestyle, dietary modifications and importantly desire and commitment to lose weight. Also it is advisable to attend educational classes and support groups for lifelong healthy habits and behaviours.


MYTH: Bariatric Surgery has high risks.

Weight loss surgery was considered a risky surgery in 70’s due to lack of technologies, large incision, inexperience staff and reduced follow ups. All of these factors have changed markedly. Today, weight loss surgery is performed very safely with low risks in the hands of experienced surgeons, advanced laparoscopic technologies and experienced staff with regular follow ups. It’s risk is not more than the other performed surgeries like uterus removal etc.


MYTH: One has to be over 100 kilograms to qualify for bariatric surgery.

Selection criteria for weight loss surgery depends on the Body Mass Index (BMI), it is a mathematical formula which is calculated by dividing weight(kg) by height(m2) and presence of co - morbidities (like diabetes mellitus, blood pressure, obstructive sleep apnea, poly cystic ovary syndrome, joint pains, etc.

For Indian population, to qualify for bariatric surgery, BMI of 35kg/m2 without any co morbidity or 32.5 kg/m2 with co-morbidities is required. Recent studies have shown that individuals with lower BMI (as low as 30kg/m2) with uncontrolled diabetes have been benefited from bariatric surgery. Each individual is assessed based on specific health problem, their longitivity and body mass index calculation.

Bariatric surgery is the only permanent weight loss solution which will not only make you look good by losing weight but also it is the only solutions for complicated co-morbidities.
