If you have gained an excessive amount of weight, it is difficult to lose your pounds with the help of diet and exercise. Now obesity has become a common problem due to our sedentary lifestyle, stress, unhealthy food habits, consuming an excess amount of refined sugar and flour. After a certain amount of weight gain, an individual cannot exercise correctly, and diet does not work without exercise. At that point in time doctor prescribes weight loss surgery or bariatric surgery.

The two most renowned weight loss surgeries are Roux-en-Y gastric bypass and sleeve gastrectomy. Both of these are great options because they are pretty similar. But you ask which is super-effective? We would say Gastric bypass is effective from every aspect. But it depends on person to person with their problems. 

Here in this article, we are going to give you a clear concept of gastric bypass, sleeve gastrectomy, and duodenal switch.

You are considered to be an ideal candidate if your body mass index is:

ü 40 or more than 40

Now with technological development, bariatric surgeons do all procedures through minimally invasive techniques. It means a smaller incision in the abdomen, and that ensures faster recovery. The patient can go home within a day or the next day. Individuals just need 3 to four weeks for complete healing.

Gastric bypass surgery

Roux-en-Y gastric bypass surgery is a type of operation that shrinks your stomach, reduces the calorie and fat you absorbed.

In this procedure, the bariatric surgeon disconnects the stomach on the upper portion and makes a small pouch. Next, bring a loop of a small intestine up and connect it with the pouch. It is the rerouting of the gastrointestinal tract.

Benefits: Gastric bypass is a more practical option than sleeve gastrectomy. After surgery patient usually loss 10 to 20 pounds gradually. Rerouting of the GI tract causes some good hormonal changes; these hormonal changes are considered suitable for diabetic patients.

Who is most suitable for this surgery:

  • People who excessively suffer from acid reflux, and gastritis problems
  • Patients with high BMIs
  • Patients with diabetes

Sleeve Gastrectomy Surgery

Popularly known as gastric sleeve, sleeve gastrectomy surgery is an operation only on the stomach. The bariatric surgeon only removes 80-85% of the stomach, leaving a small portion of the sleeve in its place.


Dr.Aminian, a reputed American bariatric surgeon, says that the sleeve is a little safer than gastric bypass. The associated risk of Roux-en-Y is 5% and 3% with gastric sleeves.

Who is most suitable for this surgery:

  • People with previous multiple abdominal surgeries. Rerouting the GI tract is not possible when there is a large number of scar tissues around it. At the same time, sleeve gastrectomy is minor surgery on the upper portion of the abdomen, not usually linked to scar tissues.
  • High-risk surgical patients are more comfortable with sleeve gastrectomy than gastric bypass. Here the anesthesia time is less, and the recovery time is shorter. High-risk patients are who have heart disease, lung problems, plus transplant candidate.
  • Patients with more than 450-500 pounds
  • People with multiple medications to cure psychiatric illness

Duodenal switch surgery is the combination treatment of gastric bypass and sleeve gastrectomy. 

It is capable of offering more practical consequences. In this procedure, the bariatric surgeon eliminates some portion of the stomach to make a trademark sleeve.

Then your doctor makes a more extensive version of gastric bypass surgery. And the result is potential weight loss and more excellent metabolic effects.
