Bariatric Surgical procedure leads to weight loss by restricting the amount of food the stomach can hold, through malabsorption of nutrients or by a combination of gastric restriction and malabsorption. This procedure causes hormonal changes as well. Most of the weight loss surgeries take place by using minimally invasive techniques (laparoscopic surgery). common bariatric surgical procedures are Gastric Bypass and Sleeve Gastrectomy. Your current weight, height, lifestyle, co-morbidity and general health will be helpful to the surgeon in deciding which surgery will be beneficial to you.
There are two components to the procedure; first, a surgeon creates a small stomach pouch which has a volume of one ounce or 30 milliliters. The surgeon divides the top of the stomach from the rest of the stomach.
Next, the first portion of small intestine is divided and connected with a smaller stomach pouch. After that, the top portion of divided small intestine to the small intestine further down so that stomach acids and digestive enzymes from the bypassed stomach and the first portion of small intestine will eventually mix with food.
The Gastric bypass surgical procedure works through several mechanisms, similar to most bariatric procedures. The newly created stomach pouch is considerably smaller. It satisfies by smaller meals, which results in fewer calories consumed and absorbed.
Usually, the digestion and absorption of calories and nutrients takes place in stomach pouch and segment of small intestine. Due to the smaller stomach pouch less calories are absorbed in stomach and small intestine.
Most importantly, re-routing of food stream changes gut hormones which promote satiety, suppress hunger and reverse primary mechanism by which obesity causes type 2 diabetes.
The Laparoscopic Sleeve Gastrectomy takes place by removing approximately 80 per cent of the stomach. The remaining stomach looks like a tubular pouch or a banana. This procedure works by several mechanisms; first, the new stomach pouch holds a smaller volume; so it helps to reduce the amount of food intake and the calories.
Sleeve Gastrectomy directly affects gut hormones which impact a number of factors including hunger and blood sugar control.
Sleeve Gastrectomy is as effective as roux-en Y gastric bypass with the weight loss and improvement of diabetes. Some experts say that Sleeve Gastrectomy is more effective than other weight loss procedures, as it improves Type II diabetes.
The complication rate of Sleeve Gastrectomy is very less than of the adjustable gastric band and roux-en-y gastric bypass.
