Gastric Sleeve Surgery

One of the procedures Dr. Armenta is skilled with at performing Tijuana gastric sleeve surgery. This procedure involves removing a portion of the stomach, meaning the patient won’t need to eat as much to feel satisfied. By restricting calories in this way, the patient can lose a substantial amount of weight without feeling hungry and deprived.

Gastric Bypass Surgery

Dr. Armenta can perform the mini gastric bypass surgery in Tijuana as well as the traditional, roux-en-y gastric bypass. Both are highly studied bariatric surgeries that provide patients higher expected weight loss than the gastric sleeve procedure.

* Note: There are multiple variations of Gastric Bypass surgery. The specific variation chosen for each patient is determined by the surgeon after taking into account the patient’s unique anatomy, medical history, risk factors, and other pertinent details. Additionally, the surgeon’s expertise and preferred techniques are also factored into this decision. These variations of Gastric Bypass include but are not limited to:

  • Roux en-Y proximal
  • Roux en-Y distal
  • Single Anastomosis Gastric Bypass
  • Mini-Gastric Bypass
  • Omega Loop
  • Other specialized techniques or variations
It’s important to note that the exact variation used may only be determined after an in-depth laparoscopic examination during the surgery itself. This ensures that the most suitable method is selected for optimal patient outcomes. Requesting a form of the Gastric Bypass is acceptable but please know it is not guaranteed.
Dr. Rene Armenta continues to study and practice the latest innovations and treatments with laparoscopic methods. If you want a surgeon who cares about you and wants to see you succeed, you’ll find that at Renew Bariatrics, with Dr. Armenta.

Dr. Rene Armenta Reviews


Everything went just as planned. I was picked up at the airport on time (the drivers were great.) My surgery and time at the hospital was a positive experience. I felt safe and cared for. Dr. Armenta and the hospital staff were amazing. The hotel they set me up in was nice and conveniently located. The Renew staff was in contact with me several times pre and post-op. The coordinators and nutritionist have been very informative and helpful. No complaints.


I was very happy with the service I received. From the moment I was picked up from the San Diego airport by their transport, I felt very safe. All the nurses were very kind and friendly and they answered all of my questions. Dr. Armenta was great. 10/10 would recommend.


Dr. Armenta was very informative and eased any concerns I had! The staff was phenomenal, very attentive and kind. I loved seeing them enjoy their jobs too, you don’t get to see that often in medical facilities in the states. 10/10 would recommend renew to anyone looking!


I had surgery on 1/10/2022. I can tell you I had the absolute best care and experience. I received better care there than I have ever received in the US. The staff and nurses are on top of it. Dr. Armenta was amazing and would answer any and all questions I had. Thank you for changing my life for the better!


My surgeon, Dr. Armenta was great. Easy to talk to and answers all questions. Staff , RN’s CNA’s were all on point. Didn’t have to wait for them to come to room. Hospital is modern and exceptionally clean. A great experience and would recommend this hospital and doctor without a doubt.


This has been the best experience. As a nurse, I’m picky when it comes to healthcare - but this has been a fantastic experience. The whole staff is experienced and efficient and Dr. Armenta (my surgeon) is amazing!
