1) Restrictive Procedures
The size of the stomach is reduced to 50-100cc, but the advantage is that food digestion happens through the normal digestive process. The two most popular procedures are Gastric Banding and Sleeve Gastrectomy.

2) Malabsorptive Procedures
By bypassing a given length of the intestine, the absorption of the nutrients are reduced thus reducing the weight in the long term. Intestinal bypass & Transposition are two procedures performed by this technique and is not very popular with surgeons and patients as well.

3) Combined Procedures
By adding the malabsorptive component along with the restrictive approach by a way of bypassing a length of the intestine giving the patient the most successful results with prevention of major co-morbidities. Immensely popular Gastric Bypass and Duodenal Switch are performed by this technique.

• Gastric Banding(LGB)
This is one of the most popular obesity surgery techniques. It is more useful for patients with a BMI of 35 and above without co-morbidities. A soft band is placed around the stomach shaping it like an hourglass. A pump is fixed beneath your skin which controls the amount of food allowed through the hourglass stomach. This reduces the amount of food you consume at one time and makes you feel full sooner and for a longer time. You therefore eat less and lose up to 50-60% of your excess body weight.

• Sleeve Gastrectomy(LSG)
It’s a newer surgical option and fast gaining popularity for the simple reason that it is more patient compliant due to the fact that your hunger is also diminished after the procedure. It is more useful for patients with a BMI of 35 or above without co-morbidities. The size of the stomach is reduced by cutting it like a tube. This also reduces hunger, which makes you feel full with a less quantity of food and for a longer time and subsequently lose more than 60-70% of excess body weight.

• Gastric Bypass(RYGBP)
The most demanding, yet the most popular and successful surgical option for obesity where you will lose weight and never regain it. It is more useful for patients with a BMI of more than 40 and above or for BMI>35 with co-morbidities. The size of the stomach is reduced and the digestive process is altered. You will reduce the amount of food you eat in one meal and thus absorb less of the food you eat and become intolerant to food you should avoid (sweets & fats). Your weight loss will be in line with around 85% of excess body weight.
