Gastric bypass surgery is a weight loss (bariatric) surgery for obese people who are looking for a quick solution to their obesity problem and want to see significant improvements in their health. Commonly performed using the minimally-invasive laparoscopic surgery, gastric bypass has several variations, the most common version being Roux-en-Y.

In this article, we are going to explore gastric bypass surgery, its pros and cons, cost, and recovery tips, and provide you with some information about this type of weight loss surgery in Iran.

How can I arrange my gastric bypass surgery in Iran?

Gastric bypass is performed using the minimally-invasive laparoscopic technique in Iran. The surgeon makes a few incisions to the patient’s abdomen and inserts the laparoscope and other surgical instruments and performs the operation. For a better understanding, watch the video simulation.

How does gastric bypass work?

The Roux-en-Y gastric bypass works in two ways to trigger weight loss.

Malabsorption: helping your body absorb less food

Since the larger portion of the stomach and a part of the small intestine is bypassed in a Roux-en-Y gastric bypass, the absorption of calories is greatly reduced, prompting an even faster weight loss.

Because of these two functions, gastric bypass is a restrictive-malabsorptive weight loss surgery.

After gastric bypass surgery, you will fill full a lot sooner. Plus, less amount of food will be absorbed and turned into excess weight.

Pros and cons of gastric bypass surgery

Each type of weight loss surgery has some advantages and disadvantages. The main benefits and drawbacks of gastric bypass are as follows:

Preparing for gastric bypass surgery

The more informed you are about the procedure the less anxious you will be before surgery. Consulting a surgeon before your surgery helps you get a good understanding of the procedure, results, and your life after surgery.

Gastric bypass surgery process: how is it performed?

A gastric bypass is performed under general anesthesia. It means that you will be unconscious during the procedure. Today, most doctors use laparoscopy to perform a gastric bypass. In this technique, which is also called keyhole surgery, the surgeon makes small incisions in the abdomen through which he/she inserts surgical instruments, a laparoscope (a long instrument with a light and camera at its end, used to see the inside of the body), and a tube to perform the operation.

The gastric bypass surgery is performed in two main steps:

  • The first step involves dividing the stomach into two sections and sewing them up using staples. The upper section, called a pouch, is much smaller than the lower section. It is about the size of a walnut and is going to hold the food you eat. Since it can hold a very small amount of food, your appetite will be reduced dramatically, hence the weight loss.
  • The second step is cutting the small intestine into two sections. The lower section, which includes jejunum and is called “Roux limb”, is then connected to the small pouch, so that the food would pass directly from the small pouch to the jejunum, bypassing the main part of the stomach and the first part of the small intestine (duodenum). In the end, the end of the duodenum is reattached to the small intestine at a lower point to allow flowing of other digestive juices.

Gastric bypass recovery and post-operative care

  • Chew carefully. Food has to become like a pureed food before swallowing;
  • Don’t drink while eating,

For a complete guide to eating after bariatric surgery, read “Healthy eating guidelines for the first month after weight loss surgery”.

Gastric bypass complications and side effects

There is no doubt that any kind of surgery might cause a number of side effects and complications.

Possible risks of gastric bypass are blood clots in legs (preventable by taking blood-thinning drugs), leakage in the connection area between the stomach and small intestines, dumping syndrome, difficulty in swallowing, diarrhea, indigestion, sagging skin, nausea, vomiting, bloating, allergic reaction to anesthesia, Stomal stenosis, infection, and bowel obstruction.

Most of the complications can be prevented by following your surgeon’s instructions and adhering to a healthy diet and lifestyle. Constant visits help you avoid many of the mentioned complications.

Mini gastric bypass surgery

Mini gastric bypass surgery (MGBS) is a simpler less invasive procedure, compared to the regular gastric bypass. In this surgery, a banana-shaped pouch is created in the stomach and then connected to the small intestine through a so-called anastomosis, bypassing a portion of the small intestine. The mini gastric bypass works the way a Roux-en-Y gastric bypass works.

Gastric bypass vs gastric sleeve: which one is better?

Furthermore, it is important to consider the similarities and differences between the two surgeries in order to make an informed decision.

Similarities between gastric bypass and gastric sleeve

  • After both procedures, you will eat less because your new stomach will hold a small amount of food
  • You need to stay in hospital after both gastric bypass and gastric sleeve surgeries
  • Both procedures cannot be reversed
  • The recovery period for both surgeries are almost the same
  • Both procedures deliver a significant weight loss

Differences between gastric bypass and gastric sleeve

  • In the gastric bypass, the stomach is not partially removed from the body while in the gastric sleeve a large portion of the stomach is taken out.
  • Gastric bypass changes the way your digestive system handles the food but in the gastric sleeve, the digestion doesn’t change.
  • Gastric bypass is both a restrictive and a malabsorptive surgery, which means it both make you eat less and reduces the absorption of nutrients by bypassing a portion of the small intestine, while the gastric sleeve is a restrictive procedure only.

A practical point for your care

Weight-loss surgery requires a personalised eating plan, monitoring of nutrition and long-term follow-up. Follow the bariatric team’s staged diet and supplement instructions rather than using a fixed online schedule.[1]
