Gastric Bypass Surgery – Tijuana Mexico

Gastric bypass surgery in Tijuana Mexico  is one of the most successful weight loss procedures that Dr. Jorge Maytorena performs; his patients have shown amazing weight loss results and have changed their lives after this procedure. This surgery is a metabolic procedure, which means that after the surgery you as a patient will have the great benefit of not absorbing fat and sugar the same way as before, that is why it is also called a malabsorptive procedure. 

During surgery, Dr. Jorge Maytorena staples a large section of the stomach leaving a small pouch, creating a certain level of restriction. Next, a section of the small intestine is attached to the pouch to allow food to be digested bypassing the lower stomach and much of the small intestine so it does not metabolize fat and sugar the same way. The small pouch can only allow a few ounces of food at a time, fewer calories and nutrients are absorbed due to bypassing the stomach and intestine. Thus patients eat less, absorb fewer calories and lose weight. Gastric bypass is typically reserved for patients who are more than 100 pounds overweight. The smaller stomach is connected directly to the middle portion of the small intestine (jejunum), bypassing the rest of the stomach and the upper portion of the small intestine (duodenum).

Dr. Maytorena performs this (like every other procedure) laparoscopically; this means, that during surgery he makes 6 small incisions in the abdominal area and uses very precise instruments, as well as a camera to guide the surgery. Laparoscopic surgery is the best possible way to have this procedure done because it hugely minimizes risk and along with great results, it diminishes recovery time drastically so the patient can start feeling results faster.

  • Malnutrition
  • Stomach perforation

Upon your arrival at the San Diego International Airport, our designated driver will be there to greet you and transport you to our facilities. Upon arrival, you and your companion (if applicable) will be provided with accommodations for the night. Ensuring your comfort and relaxation is paramount as you prepare for the surgical experience scheduled for the following day.  You will check-in and will be shown to your room, which is a single or double room with its private bathroom, heating, and air conditioning, Wifi all the necessities for a successful surgery experience.  


The following morning your process will start at 7:00 am at the hospital,  Pre op testing will start.  

Right after, you will have a visit from our internal medicine doctor who will perform an EKG as well as take some blood samples so they are sent to the lab.  Once the lab results come back, you will be prepared for surgery. Before you go to the operating room, you’ll meet both  Dr. Maytorena and his surgical staff, you will be able to ask the doctor any questions you might have as well as an explanation of what the surgery entails and what to expect. Then you will be ready to go into surgery. 


As mentioned before, all Dr. Maytorena’s surgeries are performed laparoscopically, which involves inserting instruments through multiple small incisions in the abdominal area.

After making the incisions with the laparoscopic technique, Dr. Maytorena cuts across the top of your stomach, sealing it off from the rest of your stomach. The resulting pouch is about the size of a walnut and can hold only about 4 ounces of food. Normally, your stomach can hold about 3 pints of food.

Then, Dr. Maytorena cuts the small intestine and sews part of it directly onto the pouch. Food then goes into this small pouch of stomach and then directly into the small intestine sewn to it. Food bypasses most of your stomach and the first section of your small intestine, and instead enters directly into the middle part of your small intestine.

Surgery usually takes from an hour and a half to two hours. After surgery, you awaken in a recovery room, where the medical staff monitors you for any complications.


Immediately after gastric bypass surgery, you may have liquids but no solid food as your stomach and intestines begin to heal. You’ll then follow a 4-week post-op special diet plan that changes slowly from liquids to pureed foods. After that, you can eat soft foods, then move on to firmer foods as your body is able to tolerate them.

You may have many restrictions or limits on how much and what you can eat and drink. Dr. Maytorena recommends you take vitamin and mineral supplements after surgery, including a multivitamin with iron, calcium and vitamin B-12.

Back home you may also have frequent medical checkups to monitor your health in the first several months after weight-loss surgery. You may need laboratory testing, bloodwork, and various exams just to make sure you are in good health and getting the nutrients you need.

You may experience changes as your body reacts to the rapid weight loss in the first three to six months after gastric bypass, including:

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


Gastric bypass can provide long-term weight loss. The amount of weight you lose depends on your type of surgery and your change in lifestyle habits. It may be possible to lose 90 percent, or even more, of your excess weight within two years.

  • Gastroesophageal reflux disease
  • Heart disease
  • High blood pressure
