Sleeve Gastrectomy, also known as gastric sleeve surgery is a weight loss surgery restricts the amount of food you can eat by reducing the size of the stomach. The minimally invasive procedure removes a portion of the stomach, making the stomach roughly the size and shape of a banana.
Patients who have had a sleeve gastrectomy feel full after eating much less. In addition, the surgery removes the portion of the stomach that produces a hormone that can make you feel hungry, so you won’t want to eat as much.
This procedure can be an excellent alternative to gastric bypass, and it is a simpler procedure because it doesn’t involve rerouting or reconnecting the intestines. Also, the sleeve gastrectomy doesn’t require implanting a banding device around a portion of the stomach.
For certain patients, in particular those with a body mass index (BMI) greater thn 60, the sleeve gastrectomy may be the first part of a two-stage operation. In the staged approach, the operation is broken down into two simpler and safer operations. In the first stage, a sleeve gastrectomy is performed. This allows patients to lose around 100 pounds or more, making the second part of the operation substantially safer. Some people lose enough weight that they do not need any additional surgery. For those who continue to the next stage, the second procedure is usually performed eight to twelve months later, and the “Sleeve” stomach is converted to a gastric bypass.
On an average a person loses maximum weight in the first three months after surgery and the weight loss depends on the age, weight, BMI, height, co-morbidities and weight loss attempts of the patient previously. But a person can lose anywhere between 15-25kgs in the first three months after surgery.

In a Lap band procedure, the surgeon places an adjustable ring around the upper part of the stomach thereby tying off most of the stomach and leaving a very small area. There is severe discomfort if the patient over eats thereby aiding in weight loss. In a gastric sleeve surgery the greater curvature of the stomach pouch that secretes a hormone called ghrelin, excess secereting part of that hunger hormone is removed thereby reducing hunger and cravings. since Lap Band is Less consistently effective than other procedures. Additional adjustments procedures are required, The rate of complications may be higher, Many patients end up seeking revisions to sleeve gastrectomies Whne the two are compared sleeve gastrectomy is the best option amongst the two. Though more invasive and has a longer recovery time, gastric sleeve is way more effective with less probability of reoperation and complication
