Bariatric Surgeons Dr. Ariel Ortiz and Dr. Arturo Martinez

Obesity Control Center (OCC) is a state-of-the-art facility where over 25,000 successful weight-loss surgeries have been performed. The hospital boasts Master Surgeons, unrivaled technology and groundbreaking techniques to provide patients with highly safe and effective bariatric surgery. Because of its high standards, Obesity Control Center is a popular medical tourism destination for patients from the United States and other countries abroad. 

Obesity Control Center is the most reliable choice for weight loss surgery procedures. In fact, more weight loss surgeries have been performed at Obesity Control Center than at any other location in the world.

OCC’s surgeons have improved the traditional gastric sleeve method with a custom “double-buttress  technique” to better secure the seal and prevent leaks and stretching. Patients may also choose the new “Stomach Sparing” gastric sleeve method.

Obesity Control Center is the exclusive provider of the Dual Long Limb technique for gastric bypass, which is usually the most suitable surgery for morbidly obese patients. Some patients may be candidates for a mini gastric bypass.

Patients looking for revisions to previous surgeries — such as adjusting lap band, converting lap band to gastric sleeve, or revising or tightening gastric sleeve — can find help at Obesity Control Center.

While many bariatric facilities only treat adults, OCC’s surgeons regularly perform weight-loss procedures on adolescent patients.

The surgeons work with each patient to determine which procedure is the right fit for the patient’s needs. Moreover, the entire staff is committed to providing excellent aftercare so that patients stay on track for a fulfilling weight-loss journey and permanently healthy lifestyle.

What Do Patients Say about Obesity Control Center?

“I absolutely would recommend OCC to anyone who is interested in weight-loss surgery. From the minute I reached out with questions they have been nothing but helpful… I am down 120 pounds from my highest weight 8 months ago.”
– Taylor S.


“The staff at OCC have been extremely supportive, reassuring and professional. I followed their pre-op and post-op directions exactly as outlined and I have had nothing but success… Dr. Ortiz and his staff have truly created a world-class center!”
– Elizabeth N.


“My weight was killing me. I researched my options and decided on OCC and Dr. Ortiz. It was the best decision of my life. I’m almost 5 years out and have not regretted it a single day since. I lost over 70 pounds and feel like I got my life back. The experience was great and having it done in Mexico was a non-issue.”
– D.R.
