Why revise?
You haven’t reached the weight loss expected after your first surgery.
You lost weight as expected, then regained a large part of it. Why weight can return.
Problems such as a slipped band, a stretched pouch or sleeve, or a widened bypass outlet.
Chronic reflux that medication doesn’t relieve, persistent vomiting or malnutrition.
Revision isn’t always surgery. Nutrition support, GLP-1 medication and endoscopic treatment are also options, as the ASMBS statement on weight recurrence explains. Our surgeons review why your first surgery isn’t working before recommending anything.

| What it does | Often considered for | At Renew | |
|---|---|---|---|
| Sleeve to gastric bypass | A small pouch is made from the sleeve and connected to the small intestine, so food bypasses part of it | Reflux, and weight that wasn’t lost or came back | Custom quote |
| Sleeve to mini gastric bypass | The sleeve is connected to a loop of small intestine with one connection | Weight that wasn’t lost or came back | Custom quote |
| Sleeve to SADI-S | The sleeve stays, and the duodenum is connected to the lower small intestine | More weight loss and type 2 diabetes | Dr. Pérez, Tijuana and Cancún. Custom quote |
| Re-sleeve | The stretched sleeve is made narrow again, much like the first surgery | A sleeve that has stretched or widened | Custom quote |

| Lap-Band to gastric bypass | The band is removed, then a Roux-en-Y gastric bypass is performed | More weight loss, or reflux | SER Hospital, Tijuana. Custom quote |

Assessment first
What the research says
Revision surgery has more risk than a first operation because your surgeon works on tissue that has already been operated on.
Getting started
Our surgeons may ask for your operative report, recent labs or imaging before recommending an option. About Dr. Pérez.
Send your health history and records from your first surgery, and our surgeons will review them. Virtual consultations are available.

“I had a revision from Gastric Sleeve to a Bypass on 4/28/22. I had the most amazing experience ever at Renew! I am so grateful I had my surgery with them instead of in the states!”
“Absolutely loved my time here. I had previously had a sleeve performed in the states, but came here for the bypass Revision and so glad I did. All the staff were super friendly and the nurses and doctors answered all questions I had during the procedure.”
“Dr. Perez was outstanding. He said I was one of his difficult cases because of all the scar tissue from having my lap-band removed in 2024. He was able to complete my sleeve, and I feel great. I’m a RN in the US and the care I received was very high. This was the best decision ever with the best doctor!”

A second procedure for people who have already had weight-loss surgery and haven’t lost the weight they expected, have regained it, or have complications. It can change, convert or undo the first surgery.
After a gastric sleeve: conversion to gastric bypass, mini gastric bypass or SADI-S, or a re-sleeve. After a gastric bypass: TORe. After a Lap-Band: conversion to a gastric sleeve or gastric bypass, or removal.
TORe is $8,599 all-inclusive. Other revisions are custom quotes after your medical review, because the price depends on your first surgery and what needs to change.
Not always. Regain can have several causes, and nutrition support, GLP-1 medication or an endoscopic procedure may be options. Our surgeons review your history before recommending anything.
Yes. Send your records from your first surgery with your health application, and our surgeons will review them.
Yes. Your surgeon works on tissue that has already been operated on, so the risk of complications is higher. Endoscopic options such as TORe have lower risk than surgical revision.
