Obesity Control Center is considered one of the best facilities for weight loss surgery — not only in Mexico, but the world. Our award-winning team of bariatric surgeons has a combined 50 years of experience with over 26,000 successful bariatric surgery procedures to our credit. We were one of the first centers to perform bariatric surgery anywhere in the world. Because Obesity Control Center holds itself to the most rigorous medical and safety standards found anywhere in the world, patients from Mexico, the United States, and every corner of the globe seek care from our weight loss surgeons. We are fully accredited by the Joint Commission International and have also been awarded their Golden Seal a distinction recognizing the highest standards of safety: a complication rate of less than 1%.

Two master bariatric surgeons — Dr. Ariel Ortiz® and Dr. Arturo Martinez — care for every patient. That means that Obesity Control Center patients are always in the hands of a world-renowned and highly trained surgeon. Our surgeons are pioneers in the field, with accomplishments that include being the first to provide teenage obesity treatments and creating the IGS Improve Gastric Sleeve®, the Stomach Sparing Gastric Sleeve®, and the Double-Buttress Sewing Technique. At our state-of-the-art facility, our surgeons offer several types of weight loss surgery, including gastric bypass, gastric sleeve, lap band surgery, and gastric plication. During the consultation phase, the weight loss surgeons will evaluate each patient individually to create a customized surgical plan that considers the patient’s goals, concerns, preferences, and medical history. Dr. Ortiz and Dr. Martinez received their advanced education in bariatric surgery at elite educational institutions and have been invited to instruct the next generation of weight loss surgeons as professors and guest lecturers.

In addition to changing their patients’ lives with bariatric surgery, they are innovators in their field who have developed safer and more efficient ways to perform weight loss surgery. The entirety of Obesity Control Center’s staff in Tijuana is just as beloved by patients. We offer five-star accommodations to our medical tourism patients, with round-the-clock concierge service. It is our pleasure to ensure that you travel to and from our weight loss center safely and comfortably.

Another reason patients choose Obesity Control Center is that our surgeons and staff care about our patients’ well-being well after they return home from bariatric surgery. We commit to providing five years of postoperative care, including a personalized nutrition and exercise plan, so that patients meet their goals and feel adequately supported during their weight loss journey.


As one of the first International Centers of Excellence outside the United States, it means that our weight loss surgery patients receive exclusive and unparalleled care in the most advanced facilities. This designation is awarded after a series of rigorous onsite reviews over a year-long period where every facet of the practice, the staff, the surgeons, and the facilities is examined by experts in the medical field to ensure that only the highest standards are consistently maintained. Very few international hospitals achieve this status, and many American hospitals do not. As a result of this designation, patients are assured that they will not be sharing their environment with diseased patients or infectious diseases common in other hospitals that are not fully specialized in weight loss surgery. Our Tijuana, MX bariatric surgery facility has also passed the highest standards of excellence established in the United States that equate to safe and effective weight loss procedure. Because of our highly specialized environment, we have redundancy in all the necessary state-of-the-art equipment and expert staff to meet any need the weight-loss surgery patient may require. Our pristine and modern facility is only surpassed by our compassionate English-speaking staff that takes care of patients every step of the way.

Medical Tourism

It is completely safe to travel to Mexico and have surgery with us at OCC. Over 100 people from the USA come to Mexico every single month to have surgery with Dr. Ortiz or Dr. Martinez and achieve optimal results. We even take care of patients by shuttling them between the hotel and hospital, as well as across the border.

We have passed the most rigorous accreditations and now display a List of Awards and Designations of Quality bestowed upon the Hospital and the Surgeons. In order for the Obesity Control Center to be awarded the various distinctions and designations by third party quality accreditation organizations, we had to go through rigorous year-long reviews that examined every aspect of our practice, including the staff, surgeons, and facilities.

We are one of only a few international hospitals to be awarded these designations. We are fully accredited as a Center of Excellence in Bariatric and Metabolic Surgery and our Surgeons have been designated Surgeons of Excellence in Bariatric and Metabolic Surgery, and have also obtained the Golden Seal awarded by the Joint Commission International that signifies that we have met the highest standards in patient safety and quality available in healthcare.

If you have any questions or concerns about traveling to Mexico for bariatric surgery, please contact The Obesity Control Center. A member of our team would be happy to speak to you about what you can expect during your weight-loss surgery process.
