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 have a combined 50 years of experience with over 25,000 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 as a Center of Excellence in Bariatric and Metabolic Surgery. We also have been awarded the Golden Seal by Joint Commission International, a distinction recognizing our highest standards of safety: a complication rate of less than 1%.

Three master bariatric surgeons — Dr. Ariel Ortiz, Dr. Arturo Martinez and Dr. Santiago Horgan — 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, Dr. Martinez and Dr. Horgan 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 because 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.

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.
