Mini Bypass

The mini-gastric bypass procedure consists of creating a smaller stomach pouch and attaching the terminal part of the small intestine to the new stomach. The body's normal digestive process is altered, restricting food intake and the number of calories the body absorbs. As a result, food bypasses a large part of the stomach and most of the small intestine. It is great for revising a failed sleeve or other failed procedure.



With over 20 years of experience and 25,000 successful procedures with an industry-leading safety rating, Obesity Control Center is a premier Mexico destination for safe and effective mini-gastric bypass and other bariatric surgery.

The mini-gastric bypass procedure consists of creating a smaller stomach pouch and attaching the terminal part of the small intestine to the new stomach.

The body’s normal digestive process is altered, restricting food intake and the number of calories the body absorbs. As a result, food bypasses a large part of the stomach, and most of the small intestine. This procedure’s use around the world has increased considerably in the last decade due to the considerable technical difficulty of the conventional gastric bypass, even for experienced surgeons.

Mini-Gastric Bypass vs. Gastric Sleeve?

These are different procedures and work differently. They both have their pros and cons and this question is the one you would definitely want to discuss with the surgeon doing the procedure. We really like the least invasive procedure that can get you the best results. This is why we always recommend a gastric sleeve before the gastric bypass. You can always move up to a bypass from a sleeve, but not the other way around. To learn more about the mini gastric bypass, visit

Mini Bypass FAQS


Are you a candidate for Mini-Gastric Bypass?

If you are considering any type of bariatric (weight loss) surgery, then you likely already know the frustration of not being able to lose weight on your own. You are a good candidate for this surgery if:

  • Your weight gain overwhelms you.
  • You’ve tried countless other diets, only to watch your weight quickly return to previous levels or increase even higher
  • You lack the physical ability or willpower to implement a rigorous exercise regimen
  • You are concerned that obesity is posing a serious risk to your health
  • You’ve been diagnosed with diabetes, high blood pressure, high cholesterol or triglycerides, insulin resistance or other metabolic problems
  • Your inability to lose weight causes depression or feelings of hopelessness

How do I prepare for gastric surgery?

Like in life, mental, physical, and nutritional preparation is essential for a successful outcome. Additional requirements may be suggested depending on your specific case.

Preoperative weight loss will detox your liver, making it lighter, and resulting in a quicker, safer weight loss procedure with less impact on your overall status. Even 5% of total body weight loss will result in a dramatic improvement in your ability to respond to surgical stress.
Nourishment at a cellular level will require you to compensate for the deficiencies you have accumulated over the years and the deficiencies expected after weight loss surgery. Research has proven that the only way to replenish these deficiencies is through Bariatric Supplementation.

This means that a Bariatric Multivitamin and a Bariatric Protein source prior to the Gastric Bypass will enormously increase your safety profile and a successful outcome. Mental preparation includes looking at the way we relate to food and being proactive about a healthier diet and lifestyle.

What are the advantages of Mini-Gastric Bypass?

This procedure represents a significant reduction of technical complexity, shorter operative time, and a potential reduction in morbidity and mortality. Studies show a benefit of 75% excess weight loss and resolution of comorbidities equivalent to those observed after conventional gastric bypass.

What’s the price for a Mini-Gastric Bypass?

Depending on the type of gastric surgery requested, prices can vary from around $6,500 to $9,000 dollars. We suggest you look into testimonials online, talk to other patients, and don’t be misled by price. The savings by coming to OCC is around 50% of the cost in the US. Don’t risk it by looking for the lowest price. Your health and wellbeing are very valuable.

Included in the cost of your gastric bypass surgery:

  • 1 night stay at our world-renowned hospital
  • 1 night stay at a local 5-star hotel
  • Luxury transportation to and from the San Diego International Airport
  • Team of three Board Certified surgeons, including two anesthesiologist
  • All operating room costs and surgical materials
  • All pre-op evaluations and follow-up care

Why is gastric surgery called ‘Metabolic surgery’?

In the fight against obesity and excess weight, the only proven method that outlasts common methods is bariatric surgery. Recent advances in the field have proven that these weight loss surgeries not only dramatically influence the excess weight a patient carries, it also balances out the metabolism of an individual, especially the insulin and blood sugar levels. This is why weight loss surgery is now called ‘Metabolic surgery’. It is not completely understood how exactly surgery regulates insulin, blood sugar, diabetes, cholesterol, lipids, and sleep disorder (sleep apnea), but it is a fact that it has a direct impact and controls, and many times cures these life-threatening diseases.


Gastric Surgery in Mexico, really?

At OCC, we have over 25,000 patients that have traveled to our center with no major security incidents to report. We are at the heart of the commercial district, less than half a mile away from the international border to the U.S.A. Tijuana is now the second busiest medical destination for the traveling patient. At OCC, we are glad to be an essential part of this great reputation.

How safe is Gastric Bypass Surgery?

OCC’s complication rate is one of the lowest in the published literature.

Is Gastric Bypass Surgery painful?

The OCC Difference means we perform all gastric procedures laparoscopically, which is minimally invasive. Laparoscopic surgery usually results in a shorter hospital stay, faster recovery, smaller scars, and less pain than open procedures. It is actually common in any type of weight loss surgery to regain weight. The trick is to perform a procedure that limits the amount of weight that can be regained. This is done by design. At OCC, our procedures are performed to be a safe, effective, and preferably permanent weight loss solution. Weight loss has to do with a structured bariatric program – it’s not just another surgery!

Our process at OCC includes a gentle but short procedure that results in a quick recovery. The OCC difference includes specialized pencil-thin instruments and bladeless abdominal wall trocars. Localized abdominal wall blocking agents that diminish the cascade of mediators that cause pain and inflammation. We use half the amount of gas pressure, where others use 20mm/hg, we use 10 to 12mm/hg. This results in less of the dreaded “gas pressure pains” associated with laparoscopic surgery. Our operating time is a fraction of the typical time reported in the literature. We’re in no hurry, we have simply streamlined the process. Less time under anesthesia means quicker recovery times.

What are the complications?

Complications include marginal ulcers, bowel obstruction, malnutrition, and gastroesophageal reflux, including biliary reflux. Surgical complications after gastric bypass surgery, though rare, can be divided into intra-operative, post-operative, and late complications. The former generally is of particular concern for most patients because it can affect the patient’s overall quality of life.

What is the mortality rate for gastric bypass surgery?

We can say very proudly that our mortality rate is zero percent. We value health and well being and will never perform a procedure on someone who is either not well prepared medically or has a risk higher than acceptable.


Can you have a normal life after surgery?

Most patients require several months to adapt to the procedure. This is usually predictable so our nutritionist will always prescribe a nutritional regimen that is easy to follow and will allow the patient to gradually move up to the following stage. You will start with a totally liquid diet for a few days, then move on to liquids including the Bariatric Protein Meals. Slowly, you will be able to move on to mushy food and, finally, a normal diet.

Daily activities and exercise should also progress at the same rate, but the surprising fact is that most patients recover much quicker than they thought. In fact, energy levels are usually higher than expected when the nutrition plan includes the Bariatric Multivitamin and Bariatric Protein Shakes recommended by our team of experts.

The only thing you can’t do after surgery is overeating without having severe discomfort, nausea, even vomiting. Ideally, most patients will return to three normal meals a day and three snacks between meals.

How much weight should I expect to lose?

Studies conducted on gastric bypass patients show that, after one year, weight loss can average more than 75% of excess body weight. One report found that gastric bypass surgery reduced the total number of serious health problems of participating patients by 96%.

What do you eat after gastric surgery?

It starts with liquids during the first days then gradually progresses to mushy food, then semi-solids to full solids. All this happens during the first couple of months. The good news is massive weight loss occurs during this time and all the health indicators dramatically get better during this period.

Can you drink alcohol after gastric bypass?

Like any surgery, there is a recovery time and our nutrition team recommends not drinking for the first trimester. (Although a glass of wine has benefits!)

How much can your stomach hold after gastric bypass?

Patients will notice once they are past the liquid phase and eating full solids that the restriction level will result in around a third of the original meal volume. Eating a third of your typical meal will definitely induce weight loss and better overall health.

How long does it take for your stomach to heal after gastric bypass?

Recent studies show that the inner lining of the stomach can start healing in as little as 6 hours! It is important to follow all the guidelines that we teach our patients prior to surgery to ensure an uneventful recovery and a good outcome.
