Weight loss – Bariatric Surgery

Laparoscopic Sleeve Gastrectomy

Laparoscopic sleeve gastrectomy is fast becoming most popular weight loss surgeries all over the world. It is among one of the most commonly done weight loss surgeries at our centre. It is an irreversible procedure where we reduce the size of the stomach by almost 60%. The remaining portion of the stomach can only accommodate 100 to 150 ml of fluid at a time. Removed portion of the stomach reduces the hunger hormone called “grehline” to almost negligible amount. This makes person feel satisfied (early satiety) with tiny portion of food which helps in quick weight loss. Sleeve gastrectomy can help in losing between 60 – 80% of the excess weight in a period of 9-15 months.


  • Simple procedure to perform
  • The normal pathway of food is maintained
  • Normal function of the stomach is not altered
  • Less chances of vitamin and mineral deficiencies
  • No dumping syndrome
  • Hunger hormone (grehlin) levels are decreased to minimum

Roux-en-y Gastric Bypass

Laparoscopic roux-en-y gastric bypass is combination of restriction and minimal malabsorption approach. It is a reversible weight loss surgery where small stomach pouch is created by using staples. The size of pouch is equal to pear or egg size with capacity of 15 to 20 ml. Stomach is the bypassed by joining pouch and early portion of small intestine.
This process helps in feeling satisfied with small portion of food and also reducing absorption of calories. No portion of the stomach is removed in the surgery. Laparoscopic roux-en-y Gastric bypass surgery can help in losing between 70 to 80% of the excess weight in a period of 9 to 15 months.


The average extra weight loss after gastric bypass surgery is slightly higher as compare to purely restrictive procedure. Correction of co-morbidities like diabetes and dyslipidemia is also slightly better with gastric bypass surgery.


Because of slight malabsorption there is a minimal risk of vitamin B12, calcium and protein deficiencies. These can be easily managed with minimal medications.

Mini Gastric Bypass

Laparoscopic mini gastric bypass is a slight variation of gastric bypass surgery. A bigger and longer pouch of stomach is created in which small intestinal loop is joined. This procedure mainly works on principle of malabsorption and one loses upto 80% of their extra weight. Various nutritional supplements of proteins, calcium, iron and multivitamins are required for lifelong.
