Obesity Surgery – Weight Loss With Surgery

Most of us would shudder at the idea of encountering the surgeon’s scalpel for reducing body weight. We would prefer a calorie restrictive diet and intense workouts to melt the fat reserve in our body. However, some clinically obese people disabled by obesity could not adopt the conventional weight loss techniques to bring down their body mass index. For these people, obesity surgery is the best weight loss method.

Who needs obesity surgery?

A person with body mass index above 29.9 is classified as obese. However, obesity surgery is not recommended for all people with body mass index 30 or above. Morbidly obese individuals with body mass index above 39.9 could undergo weight loss surgeries. The age of the person should be between 18 and 60 years. He/she should have been diagnosed as clinically obese for the past 5 years.

Types of obesity surgery

Obesity surgery or bariatric surgery is divided into three groups – restrictive, malabsorptive and combination surgeries.

In restrictive surgery, the volume of the stomach is reduced with the help of surgery. Sleeve gastrectomy and gastric band are popular surgical techniques for reducing stomach capacity. Sleeve gastrectomy causes 60 to 70 percent weight loss. The patient usually recovers within 2 to 3 weeks. However, one should take nutritional supplements throughout life to prevent malnutrition. Gastric band could cause up to 50 percent weight loss. However, band erosion or slippage is a common complication that one might face after the surgery.

Malabsorptive process inhibits food absorption. This process causes severe nutritional deficiency. It is therefore no longer recommended for reducing body weight.

Combination procedures combine the restrictive and malabsorptive surgical methods. Through the restrictive procedure, the size of the stomach is reduced. The malabsorptive procedure creates a new shorter route for the movement of the foods through the stomach and the intestines.

There are three types of combination obesity surgeries. Gastric bypass is the most popular weight loss surgery that can cause dramatic reduction in body weight. However, the dietary habit of an individual should be modified after undergoing this surgery. A small number of gastric bypass patients experience Dumping Syndrome after undergoing the surgery. Biliopancreatic diversion is another obesity surgery that could cure morbid obesity. Obesity surgery involving gastric balloon could reduce your body weight for a short period.
