What does metabolic surgery treat?

The increasing worldwide epidemic in obesity has been related to the increasing burden of type-2 diabetes and other obesity-related diseases. Obesity is associated with a chronic inflammatory state and insulin resistance so it will increase the risk of developing various diseases (diabetes, heart disease, etc.) or worsen others (arthritis, PCOS, various veins, etc.). This is also known as “metabolic syndrome.” 42, 43

I can never express enough how grateful I am for what OCC has done for me.

I was considered overweight and obese my entire life. At 35, after years of failed diets, therapy, and research, I realized that the only way for me to permanently loose weight was to have bariatric surgery. My doctors in the US wrote letters to my insurance, emphasizing the medical necessity of this surgery. But after a year of back and forth, my insurance turned me down. I thought all hope was lost until I heard about OCC from a friend. I’d never even heard of traveling to Mexico for surgery, but, after researching and talking to the OCC, I was all in. And I’m so glad I made this choice. The amount of guidance and care I received from OCC from the moment I called for information has been better than anything I’ve experienced in the US. The procedure was smooth—I felt safe and in good hands the entire time.

It’s highly reputable reputation and accreditations.

I was sick of being sick. I suffered from type 2 diabetes and fatty liver disease. I have two small children and was sick of being tired all the time and sitting on the sidelines. I decided I didn’t want to live this life anymore. That’s when I reached out to OCC and it was the best decision I ever made. I am now actually living and making each day count.

I needed a drastic change.

I had tried losing weight and failed on my own so many times before that I just knew I could no longer do it on my own. My health insurance benefits excluded weight loss surgery and I felt so defeated! I didn’t want the insurance companies to decide what I knew I needed. It wasn’t until I started searching for cash-pay costs that I ran across the OCC website (and several others). I looked at their testimonials and tried to find some of those people – I reached out to them on social media to get their thoughts. I started doing research on Dr. Ortiz. I researched the accreditations and certifications that the OCC held and was liking what I was learning. I looked into other facilities and Dr.’s, but none of them seemed to have as high of standards as OCC. After doing research and talking with others about their experiences both at OCC and at other facilities, I decided that it was time to get more information directly from OCC.

OCC, you gave me not only my life back, you gave me my smile back…

I have struggled with my weight my entire life. In the long run it became not only emotionally, but also medically necessary to make a drastic change in my life. I was recommended by a family friend who is also a Nurse Practitioner and she recommended me to OCC, specifically Dr. Ortiz. Of course I was apprehensive of the thought of having surgery in Mexico but she reassured me that she took care of several of OCC’s patients right here in my hometown and that if anyone knew exactly what they were doing it was OCC. I researched OCC as well as others, both domestic and foreign, and came to the conclusion that OCC was without a doubt one of the best, if not the best. From the first call to the coordinator to the moment I left Tijuana headed back home, I was treated with support, kindness, compassion, and empathy.

I did quite a bit of reading and felt OCC was the best choice and it was!

I have struggled with my weight for all of my adult years, my highest weight was 245 at one time. I maintained my weight loss around 165 lbs until about 2 years ago when my band started not holding any fluid and realized it had a leak. I started regaining weight and put on about 50 lbs. My experience with OCC and Dr. Ortiz was wonderful! I decided to revise to the gastric sleeve and everything was great, we stayed at a very nice hotel , and the staff there was just as good. I had excellent medical care from the start. I would absolutely recommend OCC to anyone who is struggling with their weight. I am now down about 80 lbs and have never felt better. I work out with a personal trainer and run 5ks!

Safety, professionalism, knowledge, accreditation.

I was tired of being fat, and for most 215 isn’t that bad. But for me I felt disgusting. I’m use to bring the pretty sexy one. Not the chubby funny girl. I didn’t know that out of country surgery was even a possibility. I had a friend have it done in Mexico and I was like I want that. I booked with another company and after research I found that they had a death and complications. They also used drain tubes which did not sound like fun! Then I found OCC and saw all the great reviews, no deaths and no drain tubes. I was so nervous yet excited. My experience was nothing but positive. I even came home early I was doing so well. I have tried every diet, I exercised regularly and I just kept gaining. This tool has helped me so much. I still continue to eat healthy and exercise regularly but now I actually see results or my hard work. This isn’t the easy way out you still have to put the work in.

What is metabolic surgery?

Metabolic surgery alters the gastrointestinal tract to change the body’s neurohormonal environment and achieve weight loss and the remission of metabolic disease. 19-21 The procedures have many names:

  • Gastric bypass (also known as the Biliopancreatic diversion or Biliopancreatic diversion with duodenal switch): Because gastric bypass has proven to achieve such remarkable results, it now accounts for roughly half of all weight loss surgeries performed at the Obesity Control Center in Mexico. 1, 19, 23
  • Vertical sleeve gastrectomy (gastric sleeve or the Ileal Interposition): Featuring OCC’s patented “Improved Gastric Sleeve,” the safest and most effective sleeve procedure on the market with a 0% failure rate. The IGS uses the Double-Buttress Technique to create a leak-proof procedure that minimizes complications and maximizes positive results. The gastric sleeve initially began as a procedure specially formulated for the treatment of type-2 diabetes. 1, 19, 23

    Metabolic surgery vs. bariatric surgery – What’s the difference?

    How much does metabolic surgery cost?

    Depending on the type of gastric surgery performed, the prices range from about $6,500 to $9,000. The savings by coming to OCC is around 50% of the cost in the US – with a health and safety record that outstrips most US hospitals. Your health and wellbeing must be protected when undergoing metabolic surgery, and our record of success is extraordinary. Trust the experts with one of the best success rates of any bariatric clinic in the entire world, the United States included! 63-65

    How much weight can I lose?

    Studies conducted on metabolic surgery 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%. This level of weight loss can lead to the virtual elimination of a host of diseases, such as type-2 diabetes, hypertension, and high cholesterol, which significantly lowers your chances of heart and kidney diseases. 63-65

    What are the most common complications?

    Complications are rare. Leaks, bleeding, hernia, and chronic heartburn can happen, however, with over 26,000 procedures, we have streamlined the entire process of weight loss surgery. Our complication rate is one of the lowest published in the literature, with a 0% leak rate. With the implementation of the new techniques designed at OCC, our patients are experiencing substantial and permanent weight loss without the undesirable symptom of heartburn. 63-65

    Anesthesia and your recovery

    There are symptoms after having any type of surgery that are related to general anesthesia (sleepiness, dizziness, nausea, etc.) and others directly associated with the gastric sleeve itself (cramping, abdominal tenderness, vomiting). Fortunately, these are kept to a minimum and medically treated early so most patients can be up on their feet in a couple of hours and discharged the morning after. Many actually feel well enough to go out shopping the day after surgery! 63-65

    Can I have a normal life after metabolic surgery?

    Your food consumption will start slowly with a totally liquid diet for a few days, then liquids including the Bariatric Protein Meals, and slowly move into soft food, and then the transition to a normal diet.

    How long is the recovery after metabolic surgery?

    The surprising fact is that most patients recover faster than expected, and their energy levels restored with a nutrition plan includes the Bariatric Multivitamin and Bariatric Protein Shakes recommended by our team of nutritional experts.

    What happens if you overeat?

    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.

    Metabolic surgery vs. bariatric surgery – What’s the difference?

    Metabolic surgery is just another name for bariatric surgery. The difference is that this procedure not only targets obesity, but also metabolic syndrome conditions, such as type-2 diabetes, hypertension, and heart disease. To learn more about metabolic surgery, visit
