Advantages and Disadvantages of Mini Gastric Bypass Surgery

Because of the advancement in laparoscopic surgery, mini gastric bypass is being adopted by many people instead of a standard gastric bypass. It works like a standard gastric bypass by alternating gut hormones that are involved in appetite and by restricting the amount of food that can be eaten at any given time.

The stomach is divided into two parts and a small tube of the stomach is created. This tube forms the pouch. This pouch is then connected to the small intestine. The small intestine carries digestive juices from the other parts of the stomach. This way, around two meters of small intestine is bypassed resulting in lower calorie absorption and weight loss. The mini gastric bypass can be done more quickly than a standard gastric bypass. It also involves one bowel (intestine) to stomach connection where are the standard gastric bypass involves two.

As of today, the mini gastric bypass has not been graded as better compared to the standard gastric bypass. There is not much difference in both the procedures. The weight loss is considered to almost the same in both the bypasses. However there are few great advantages that are linked to the surgery and a few disadvantages also.


  • The procedure is completely reversible. If the person is not recovering well or is unable to cope with the changes in the body following the surgery, there is no need to worry. The procedure can be reversed either during the recovery period or can be undone some time later in life if the patient feels that it is no longer helpful.
  • The cost of the procedure is less. Since the procedure is less complicated, it involves lower cost for the patient.
  • The recovery time is just one day, typically. It usually takes a person one day to recover completely from the surgery.
  • The weight loss ranges from 50% to 80% of body fat like other surgeries.
  • The surgery takes less than an hour in the operating room and is done laparoscopically.
  • The procedure will decrease hunger considerably. The patient will feel a considerable difference in appetite after the surgery is done.


  • There are no long-term studies or research available on the surgical procedure. Therefore it is hard to determine if the procedure will have benefits in the long run.
  • The digestive juices in the small intestine can reflux. This can cause ulceration, inflammation or erosion around the stomach walls.
