Gastric Bypass

What is Laparoscopic Gastric Bypass?

laparoscopic gastric bypass surgery is considered one of the best weight loss surgeries which involve the surgeon stapling the top portion of the stomach thus creating a smaller stomach pouch. The smaller size of the stomach pouch reduces the food intake.

A section of the small intestine (jejunum) is connected to this small stomach pouch permitting the food to bypass the lower stomach (duodenum). This procedure reduces the amount of calories that body can absorb this phenomenon is called malabsorption. This surgery is also called Roux-en-Y bypass.

What are the benefits of the


The benefits of the surgery are as follows:

  • The surgery increases the average rate of weight loss if you rigorously follow instructions than with other restrictive procedures.
  • Studies show that a year after the surgery the percentage of weight loss stands at 77% in an individual.
  • Studies also show that 10 to 15 years after the procedure 50 to 60% excess weight loss is maintained by the patients.
  • Studies also showed that the cases of back pain, high blood pressure and depression saw reduction in 96% of those patients who underwent the procedure.

How is the procedure

carried out?

Like any other laparoscopic procedure where 5 to 6 small incisions are made and through those incisions a Laparoscope (Laparoscope is a narrow tube with a camera at the end) is inserted and once the surgeon gets the clear visuals from the Laparoscope through other incisions surgical instruments are inserted and the top portion stomach pouch is stapled and the section of smaller stomach pouch is connected to the small intestine there by facilitating for the process of malabsorption. The whole procedure is carried out under the influence of anesthesia.

How long does it take to


Like any other Laparoscopic surgery the recovery time is very less compared to an open procedure.

One has to stay for 2 to 3 days in the hospital and it will take 3 to 5 weeks to resume normal activities. 

The doctor may ask the patient to get blood work and various exams to be done to monitor their health during the first few weeks of the recovery process.

As far as eating goes initially the patient has to follow special diet starting with a diet plan that changes from liquid food to pureed dishes. After this the patient can start eating softer food and then move on to eating normal food as the tolerance increases.

During the recovery process the doctors will prescribe multi vitamin and multi mineral tablets to bridge the nutrient gap and aid recovery. The prescribed vitamins and minerals may include iron, calcium and vitamin B12.

The patient may experience changes as the body reacts to the rapid weight loss in the first three to six months after gastric bypass, this includes the following:

  • Body aches
  • Feeling tired, as if you have the flu
  • Feeling cold
  • Dry skin
  • Hair thinning and hair loss
  • Mood changes
