Weight loss surgery, commonly known as bariatric surgery, incorporates various surgical procedures for reducing weight of the people suffering from excessive obesity. It can be achieved by reducing the gastric band of the stomach or removing the sleeve of gastrectomy or by re-routing the gastric bypass. Bariatric surgery is acknowledged as the first and effective choice to reduce the weight of body and to morbid obesity. There are two types of Bariatric surgeries such as Restrictive and Malabsorptive. Restrictive procedures incorporates sleeve gastrectomy, gastric banding and gastric plication which reduces the amount of foods consumed by the person whereas, Malabsorptive procedure incorporates gastric bypass which reduces the amount of food absorbed by the intestine.
2. Sleeve Gastrectomy
Sleeve gastrectomy is a restrictive surgical weight loss procedure to reduce the size of the stomach by 15% of its original size, surgically scooping out a large portion of the stomach forming a sleeve or tube like structure. This procedure reduces the size of the stomach permanently and is generally performed with the help of laparoscopic surgery. Removing the portion of stomach also decreases the level of hunger hormone (ghrelin) which leads to the weight loss. The amount of food consumed will swiftly passes through the intestine, with increasing metabolic rates helping in burning of the stored fats.
3. Gastric Bypass
Gastric bypass is also a restrictive surgical procedure for weight loss by dividing the stomach into smaller and larger portions, and also connecting the small intestine with both. The small portion of the stomach will decrease the amount of food can be consumed at one time. New anatomy will bypass the larger portion of stomach and first part of intestine which postpone the mixing of food with the digestive enzymes and cause malabsorption. It is an ideal, sustainable and rapid procedure of weight-loss.
Mini gastric Bypass is a malabsorption surgical weight loss procedure, a long gastric tube is created and connected with the middle part of small intestine. It is an easy, less time taking, reversible and effective laparoscopic surgery along with only 24hours stay in hospital. As it is also a restrictive procedure, it reduces the size of your stomach as well as restricted the excessive consumption of the food. It reduces the absorption of food by bypassing the small intestine as well as larger part of stomach.
5. Gastric Plication
The gastric plication surgery is also known as pseudo sleeve surgery as it almost functions as sleeve gastrectomy with the promise of short term results. It is not so popular procedure as the possibility of dilation for the long term still remains a concern. This is an economical, substantial and less complex procedure for the people who cannot afford the other procedures.
