There are several well documented health hazards with obesity, such as diabetes, heart disease, stroke, cancer, arthritis, liver disease, sleep apnea, and depression. The risks increase with the degree of obesity.
The most practical means of measuring obesity is the body mass index. This is calculated by dividing the weight in kilograms by the height in meters( kg/m).
BMI Categories : 25-29 overweight; 30-34 obese; 35-39 moderately obese; 40-49 severely obese; >50 super ( morbidly) obese.
Weight loss surgery (called bariatric from Greek word baros meaning weight) works by either malabsorption or restriction. Restriction procedures limit the amount of calorie intake by reducing the stomachs reservoir capacity or via creation of a blind stomach outlet. Gastric banding is a purely restrictive procedure. This limits solid food intake by restricting the stomach size as its only mechanism of action. The small intestine must then absorb nutrients. The weight loss with purely restrictive procedures is more gradual.
Malabsorptive procedures work by shortening the length of the small intestine. This is done by shortening of the small bowel or by diverting around it. Examples include jejunoileal bypass or duodenal switch operation. The weight loss can be huge, but the complications many such as protein loss or micronutrient deficiencies.
The famous Roux-en-y gastric bypass is both restrictive and malabsorptive. In this operation you are left with a small stomach pouch; however, the small bowel is rerouted favoring additional weight loss via dumping and mild malabsorption.
Let’s review some of the indications for surgery intervention: Be motivated! Have a BMI>40. Or, have a BMI>35 with co-morbidities(other diseases or complications) such as diabetes, blood pressure, apnea, severe arthritis, heart condition etc. and having failed non-surgical programs.
The most common surgical technique is the laparoscopic gastric banding. The upper stomach is banded by a tight, adjustable soft silicone ring connected to an infusion port placed under the skin.
