Clinically severe or morbid obesity is a chronic progressive condition that is very difficult to treat. Weight loss surgery for restricting food intake and interrupting digestive processes is an option for clinically severe obese patients that have been unsuccessful with other weight loss treatments. Eligible patients for “Weight Loss Surgery” often have a body mass index, or BMI, of 37.5 or greater. A BMI of 40 translates to about 45 kilos over ideal body weight for men or 36 kilos over ideal body weight for women. Weight loss surgery may also be an option for people with a BMI of 32.5 (govt of India, ministry of health guidelines) or greater who suffer from life-threatening obesity related health problems such as diabetes, obesity-related heart disease or severe sleep apnea. However, as is true for other treatments for obesity, successful results depend significantly on knowledge, personal motivation and behavior.
