I knew many people that had surgery with Dr. Ortiz. They loved him and loved their results. I was a bit hesitant at first. Let me tell you – it was the best thing I have ever done!

I could never lose weight, trust me I tried.

I could never lose the weight. I tried every fad diet, every pill they came out with, and nothing worked. I was giving up on myself. I wouldn’t get out of bed or talk to anyone. I was depressed, and disgusted with myself. When I heard about this surgery, I was scared at first. I looked into... Read more

After spending 25+ years of fad dieting and losing and gaining the same weight, I came to the realization that I was spending the majority of my time sitting on the sidelines and letting life just pass me by.

I’m finally living life to the fullest for the first time ever and I couldn’t be happier!

I was saying “no” to so many things in life because of my extra weight, causing not only myself, but my husband and my children to miss out on opportunities to live life to the fullest and make amazing memories. I’m also genetically predisposed to a long list of health issues including diab... Read more

After surgery, I worked very hard and was able to get to my current weight by the time I got married. It felt amazing to be in a dress I bought off the rack, and feeling beautiful on my wedding day was 100% worth having surgery.

I hadn’t realized how much energy I didn’t have until I had the surgery

I struggled with my weight since I was in elementary school and it really escalated when I got to college, where I had access to fast food 24/7. I had previously dieted and exercised 5-6 times a week for a couple of hours to lose a significant amount of weight, but any time a bump in the road of ... Read more

I chose OCC because of its Surgeon & Hospital Accreditations. The standards to which they follow are high and high for a reason.  There wasn’t really even a choice of other places to choose from.  OCC is rated the best and has the best real personal reviews.

A New Me

I have struggled with weight for the last 15 years.  Up, down, up, down – you all know how it goes. Hey, I’m happy – let’s eat. I’m sad – time to eat.  Let’s celebrate – let’s eat. What should we do now – I don’t know, but let’s eat. ... Read more

My name is Kylie and thanks to OCC, I’ve successfully lost 112 lbs and kept it off.

The Sleeve Changed My Life!

I wasn’t always a bigger girl, but I went through a terrible breakup when I was 20. It led to me becoming an emotional eater and consuming a lot of alcohol. I quickly packed on the weight. When I got to my heaviest, I went through another nasty break up, and I finally decided I needed to do... Read more

I was ready to take control of my life so I started researching bariatric surgeries online. I confirmed that my health insurance did not cover bariatric surgeries, so I started to research affordable options, and saw that there were all kinds of options in Tijuana. I looked carefully at several different clinics that offered Gastric Sleeve surgery, read tons and tons of testimonials, and reviews of the doctors and clinics. I decided to go with the OCC because all of the stories I read were positive. I am so happy I went with the OCC!

Gaining Control of My Life

I’ve been moderately overweight my whole life, but when I was 30 years old, I got out of a serious relationship, and my weight really packed on. Even though it was my decision to end the relationship, my self-indulgence in eating, drinking, shopping, and spending, spending, spending went co... Read more

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.
