Laparoscopic Gastric Bypass (LGB) or Laparoscopic roux-en-Y Gastric Bypass is a reversible weight loss procedure that reduces the size of your stomach to a small pouch – about the size of an egg. It is done by stapling off a section of the stomach and making food bypass the beginning of the small intestine. This reduces your appetite and makes you feel satiated with smaller portions. LGB can help you lose up to 60 - 80% of your excess weight in a period of approximately 2 years.
You can lose a lot of excess weight after a gastric bypass, up to 60 - 80%. Weight loss is the fastest in the first 3 months and the rate reduces thereafter. You will continue to lose weight for a year and a half until 2 years. After that, the body stabilizes and does not lose weight further in most cases. However exercise may help you lose more weight.
You will not be able to eat as much as you did prior to the operation. One also needs to be careful about 'dumping syndrome' that can occur in some patients. It occurs as a result of food passing too quickly into the intestine. It typically occurs when patients eat certain kind of foods such as sweets, certain carbohydrate sources or due to eating too much at one time. The symptoms of dumping syndrome are:
The best treatment is to keep a note of problem foods and avoid their intake. Dumping syndrome often improves on its own without medical treatment or after adjusting your diet.
At CODS we only do this procedure laparoscopically, inserting a tube with a tiny camera, called a laparoscope into your abdomen through small cuts. So unlike in an open surgery, thanks to the laparoscopic procedure you don't stay in the hospital as long and recover more quickly. You also may have less pain, smaller scars, and less risk of getting a hernia or infection.
Some patients may regain some degree of the lost weight after 2 to 3 years of surgery if they are not careful. However a healthy lifestyle, proper follow up with our nutritionists and a good exercise regime will aid in maintenance of weight loss.
You will need to be on a liquid diet for 15 days after the surgery. This is followed by 15 days of semi-solid foods and then you progress onto solids. Within 2 to 3 months you can have most kinds of food although in limited quantities.
Please note that sweet intake and intake of calorie dense foods should be kept to a minimum since it could lead to 'dumping syndrome'.
Gastric bypass patients also require a lifetime of nutritional supplementation.
