The natural means of fighting any disease are usually the most beneficial, because they ensure the absence of side effects or any complications after the desired effects have been achieved. Unfortunately, most abnormalities in physical conditions cannot be treated without medical intervention. In cases of obesity, a regimen of diet and exercise may only prove helpful in those cases where the BMI is within the range of 30 to 40. A BMI of 40 or higher indicates a level of obesity that is termed morbid obesity. Morbid obesity can seldom be controlled by diet or exercise, because after years and years of leading an inactive and sedentary lifestyle, the body naturally becomes resistant to weight loss. Also, a BMI of 40 or higher indicates that a person has to lose over 100 pounds -- an extremely daunting task.

The most popular surgery for weight loss is bariatric surgery that is now considered the most reliable surgical method to attain a weight loss that is sustained after surgery, when the patient goes back to a normal routine. A boon for people suffering from morbid obesity, bariatric surgery is considered a safe option for those with a BMI of less than 40, also. It is a means of getting rid of fat, as well as numerous weight related problems such as heart disease, type 2 diabetes and other ailments that may be potentially life threatening or may interfere with normal daily living.

Obesity surgery involves the modification of those functions of the body that support the desire and the ability to eat huge quantities of food. This surgery reduces the size of the gastric reservoir and brings about a decrease in the quantity of food a person consumes, lowering the calorie intake. This may be achieved through a number of operative procedures such as gastric bypass or vertical banded gastroplasty.

Similar to any other operative procedure, obesity surgery should be performed only on individuals for whom surgery is the last resort. Patients who are suffering from morbid obesity and have been unable to succeed in any weight loss program are potential candidates. The patient should be made well aware of the operative and postoperative risks and the long-term implications of undergoing a weight loss surgery.
