- Roux-en-Y gastric bypass:
In Roux-en-Y gastric bypass surgery, the surgeon makes a small pouch at the top of the stomach, and this new pouch is then connected to your small intestine with a tube. The tube would deliver food from the small pouch directly to your small intestine and bypasses the stomach. This operation greatly limits the stomach capacity and the amount you can eat at one sitting. thus diminishes the threshold of feeling full and you can eat significantly less food. Along with diminishing the feeling of hunger, stomach bypass also disturbs nutrition absorption. Thus malnutrition, disability of vitamins absorption and abnormal deficiency in D and B12 vitamins, are among side effects of this surgery. Stomach bypass surgery also increases the risk of dumping syndrome which would require for supplementary surgeries on hernia and gallbladder.
In the laparoscopic gastric banding, the upper part of the stomach is blocked using a band containing an inflatable balloon. The blockage decreases the capacity of your stomach to hold food and reduces the feeling of hunger. This bond is adjustable through a port which is placed under the skin of the abdomen.
One of the newest methods of weight loss surgery is using sleeve gastrectomy. In this method a substantial part of stomach is removed from the body. The remaining part of the stomach is formed like a tube-like structure, decreasing the stomach’s capacity to hold food. One of drawbacks with this method is that the results are not permanent and the loss of weight is reversible. Also this method could affect the rate of hormone secretion and produced compounds by the stomach.
- Abdominal and stomach balloons:
In this method, Stomach balloons containing air or salt is placed inside the stomach using a tube and gastro scope (endoscopy). This method decreases appetite and the food capacity in your stomach temporarily. These balloons function for six months.
- Biliopancreatic diversion:
This method works similar to stomach bypass. As stomach bypass which is performed through intestine diversion, with Biliopancreatic diversion the amount of absorbed calories is decreased significantly through omitting pancreas from food absorption process.
