Gastric Bypass Surgery in Tijuana, Mexico

Gastric Bypass Surgery, also known as Roux-en-Y (RNY), is a bariatric procedure extremely effective in reducing obesity by helping patients lose weight through:

  1. Restriction – Surgically forming an “egg-sized” stomach pouch that holds about two ounces of food (instead of the average stomach capacity of 40 ounces).
  2. Malabsorption – Rerouting a section of the small intestine which reduces the amount of food that is absorbed into the body, promoting rapid weight loss.

Mexico Bariatric Center offers the gastric bypass surgery in Mexico with some of the most trusted, board-certified surgeons. We provide minimally invasive bariatric procedures to decrease complications and increase the success rate.

How Does Gastric Bypass Work?

Gastric bypass surgery is known as the “Gold Standard” in the bariatric industry. The bypass surgery works using two methods (or components) that achieve rapid and long-term weight loss.

These two component are called Restriction and Malabsorption, which work together creating one of the most powerful combinations of weight loss treatment.

The Restrictive Component reduces the capacity of the stomach by forming a new smaller stomach pouch, called the stoma. Restriction within gastric bypass surgery enables weight loss by reducing the level of hunger hormone (Ghrelin) which causes patients to feel fuller with smaller amounts of food. This restrictive method is similar to gastric sleeve and lap band surgery.


The Malabsorptive Component occurs when the small intestines are “bypassed“, causing a significant portion of consumed nutrients and food not to be absorbed. Through malabsorption, gastric bypass surgery allows food to pass through the digestive system quickly (via the shorter small intestinal route) which reduces the number of calories absorbed into the bloodstream.

RNY gastric bypass is a powerful tool and is a more aggressive procedure than the gastric sleeve, however, it is non-reversible.

What to Expect

Besides rapid weight loss, another major benefit of gastric bypass surgery is that it is fully capable of reversing or improving the most severe comorbidities, which include type II diabetes, hypertension, high blood pressure, back pain, sleep apnea, depression, and many other obesity-related health problems.

Undergoing gastric bypass surgery in Mexico with our qualified surgeons is a safe and smart move if you’re looking to have surgery done in a full-service, certified hospital that specializes in bariatric surgery. Our team has performed thousands of bypass surgeries and we have the experience to handle even the most atypical cases.

Bypass surgery is a more effective bariatric surgery than gastric balloon, lap band, and even gastric sleeve surgery. After surgery, a majority of our patients lose most of their excess weight (averaging 70-80% excess weight loss %EWL) within the first two years.

Gastric Bypass Surgical Procedure

During the gastric bypass surgical procedure, the surgeon makes about 5 or 6 small incisions on the belly and inserts trocars (hollow tubes) through the incisions as a conduit for surgical instruments. The abdomen is inflated with carbon dioxide (CO2) gas for the surgeon to have room to maneuver with organs pushed aside gently.

laparoscope (probe equipped with a built-in camera) and other surgical instruments, including a retractor to lift the liver, can now be inserted into the abdominal cavity. The cutter/stapler (normally a product of Ethicon) is used to cut the stomach and staple the stomach at the same time.

 Part One: Making a Small Pouch in the Stomach

The stomach is divided up into two by the stapler: a much smaller upper part (called pouch) with a size of a golf ball and a larger lower part (called remnant pouch). The small pouch receives food and the bottom part of stomach no longer receive food – the gastric juices from this part pass into the intestine and mix with food. An outlet called a stoma is created in the small stomach pouch (the size of a dime).

Part Two: Making the Bypass

The surgeon divides the small intestine and re-arranges it into a Y-configuration. Then the upper small intestine (the duodenum) is connected to the new stomach pouch which is called the stoma. The rerouting component is complete when the bottom portion of the small intestine is then connected (after bypassing) to the jejunum which is further down the intestinal tract.

The digestive portion of the small intestine meets with the new stoma portion of the small intestine at the common channel, where the food resumes it’s digestion process. This is why this surgical procedure is called a “Roux-en-Y.”

After the Roux-en-Y procedure, food passes directly from the stomach into the jejunum, bypassing the proximal part of the duodenum. This curbs your absorption of calories and nutrients, creating the “malabsorptive” component of weight loss

Am I Eligible for Gastric Bypass Surgery?

To be considered a good candidate for any gastric bypass surgery most patients will need to meet the following requirements:

  1. Be between the age of 18 to 62.
  2. Need to have tried losing weight with typical tactics without much success.
  3. Need to have realistic expectations regarding the result of the surgery.
  4. Need a BMI of more than 30 or with comorbidities.

Other Considerations

Gastric bypass is better suited for patients with severe acid reflux and GERD. However, if you have ulcer problem or are taking Aspirin/Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) on a regular basis, gastric sleeve or duodenal switch are better options for you. The reason for this is that there is no conventional routine to detect ulcer in the “stoma” or so-called “blind” stomach.

Not all of the requirements listed are set in stone. Our surgeons review each patient on their own to see if they could practical benefit from weight loss surgery. Learn more by contacting our staff now.

Types of Gastric Bypass Surgery

Gastric Bypass, Roux en-Y (Proximal): Proximal or short-limb RNY is the standard procedure performed. The Y-connection is connected near the upper part (proximal) or first 10 centimeters of the gastrointestinal tract (small intestine).

Gastric Bypass, Roux en-Y (Distal): In Distal Gastric Bypass or long-limb RNY, the Y-connection is connected further down the track about 100-cm (distal), allowing fewer nutrients to be absorbed. This increases the weight loss for the patient.

In distal RNY, more of the small intestine is bypassed and there will be less intestinal surface for absorption of calories, especially fat. The patient will experience more frequent bowel movements per day. The consumed fat will be digested less and will be eliminated undigested. This may cause smelly and loose stools.

Mini-Gastric Bypass SurgeryThe mini-gastric bypass surgery is a simpler alternative to traditional gastric bypass procedure. It involves a long, tight stomach that connects to the digestive tract.

The mini RNY procedure only uses one connection (single-anastomosis) through the small intestine, instead of two connections (double anastomosis) like regular RNY bypass. This is a minimally invasive and less complex process. Learn more about mini gastric bypass surgery or compare the differences between bariatric surgery types.

Gastric Bypass Revision Surgery in Mexico: Patients who have already undergone gastric bypass surgery can choose a revision or another bariatric surgery. This can arise because of many different issues, including lack of sufficient weight loss. MBC surgeons are also experienced in revision of previous gastric bypass by open incision surgery.
