Regaining weight after Roux-en-Y gastric bypass can feel discouraging. It does not mean you failed. It also does not mean another operation is your only option. A TORe procedure may help if the opening between your stomach pouch and small intestine has stretched.
TORe stands for transoral outlet reduction. A doctor passes a flexible endoscope through your mouth and down your throat and uses a suturing device on the scope to make the enlarged outlet smaller. There are no abdominal incisions. TORe slows down how fast food leaves the pouch, which can help you feel full longer and lose weight again.
| Overview | What It Means for You |
|---|---|
| Who it is for? | Certain adults with weight regain after Roux-en-Y gastric bypass who have an enlarged gastric outlet. |
| How it is done? | An endoscope and suturing device are passed through the mouth while you are sedated. |
| Incisions | No abdominal incisions are needed. |
| Going home | Many people go home the same day, although your plan may differ. |
| Early recovery | Nausea or stomach discomfort may occur for a few days. Many people return to light activities within several days. |
| Diet | Your doctor will usually guide you from liquids to soft foods and then regular textures over several weeks. |
What Is the TORe Procedure?
Roux-en-Y gastric bypass creates a small stomach pouch and connects it to the small intestine through an opening called the gastrojejunal anastomosis, or gastric outlet. This outlet helps control how quickly food moves from the pouch into your intestine. If it becomes wider over time, food can leave the pouch faster. You may feel full for less time, which can make weight regain harder to manage.
Transoral outlet reduction (TORe) is an endoscopic procedure for selected people with weight regain after gastric bypass and a widened outlet. The doctor works through your mouth with an endoscope, which is a thin, flexible tube with a camera. There are no abdominal incisions. Tools attached to the endoscope make the outlet smaller and may also tighten the pouch if needed.
The goal of TORe is to slow how quickly food leaves the pouch and help the bypass provide more restriction again. Johns Hopkins Medicine explains that this may help you feel full sooner and stay full longer, which can prompt renewed weight loss.
TORe does not redo the original bypass or change the length of intestine that was bypassed. It focuses on the widened outlet, and sometimes the pouch, when an exam shows that stretching may be part of the weight regain issue.
Why Weight Regain Can Happen After Gastric Bypass
Weight regain after gastric bypass can happen for many reasons, and it is often caused by a combination of factors. Changes in your appetite or metabolism, medications you take, and other health conditions may affect your weight. Your eating habits, activity level, sleep, and stress can make a difference too.
In some cases, the anatomy of your bypass also gradually changes. The stomach pouch or the opening that connects it to the small intestine may stretch, and when that happens, food can pass through more quickly, so you may not feel full for as long. Even then, a widened outlet may be only one part of the problem.
Because there are several possible causes, your doctor will need to understand what has changed before recommending treatment. If a widened outlet is contributing to your weight regain, TORe may be an option. Depending on your needs, your plan may also include weight loss medication, nutrition support, or changes to your daily habits. Your doctor may recommend a combination of strategies.
Who May Be a Candidate for Transoral Outlet Reduction?
TORe is for selected people who had Roux-en-Y gastric bypass and is not a gastric sleeve revision. You may be considered if you regained weight or lost less than expected and an endoscopic exam also shows an enlarged gastric outlet.
Your evaluation may include:
- A review of your original operation and any later procedures.
- Your weight history, including your lowest weight after bypass and when you started regaining weight.
- Your current eating habits, including how much and how often you eat, when you feel hungry, how quickly you feel full, and how long that feeling lasts. Your doctor will also review your activity level, medications, and health conditions that may affect your weight.
- Blood tests to look for nutrition concerns or other factors that may affect treatment.
- An upper endoscopy to measure the outlet, examine the pouch, and check for another anatomical problem.
- A discussion of the follow-up, diet, and daily habits needed after the procedure.
An enlarged outlet does not prove that it caused all of your weight regain. Your doctor will decide if tightening it is likely to help.
What Happens During the TORe Procedure?
Before your TORe procedure, the doctor will do a thorough evaluation to ensure the procedure will be safe and effective for your circumstances. You will receive instructions about fasting and medicines. Blood thinners and diabetes treatments may need special planning. Your doctor will let you know if you need to make any changes to your medication before your procedure.
During a typical TORe procedure, the following steps usually take place:
- The anesthesia team gives you sedation medicine so you remain comfortable.
- The doctor passes a thin, flexible endoscope through your mouth, down your throat, and guides it into your stomach pouch. The scope has a camera that shows the pouch and outlet.
- The doctor examines the pouch and measures the gastric outlet. This confirms how much the opening has widened and helps guide the treatment.
- The tissue around the outlet may be treated with heat to help it heal around the new, smaller opening.
- A suturing device on the endoscope places stitches around the outlet. The doctor tightens the stitches to reduce the opening and may also tighten the pouch if needed.
- The doctor removes the endoscope, and you are observed by the medical team while the anesthesia wears off. Many patients are released the same day to go home with an adult driver.
How TORe Differs From Other Revision Options
TORe Versus Repeat Bariatric Surgery
Repeat bariatric surgery uses abdominal access to change the previous operation. Based on the problem, surgery may resize the pouch, rebuild a connection, or change the intestinal route. TORe reaches the outlet through the mouth. It avoids abdominal incisions and usually has a shorter recovery.
This does not make TORe the right answer for every type of weight regain situation or every complication. A fistula, severe reflux, or blockage may call for a different plan, which may be endoscopic or surgical. Simmons MD explains the broader choices on its endoscopic bariatric revision page.
TORe Versus Gastric Sleeve Revision
A gastric sleeve and a gastric bypass make different changes to your anatomy. TORe tightens the outlet created during Roux-en-Y gastric bypass. A sleeve revision treats stretching or another problem in a sleeve-shaped stomach. If you had sleeve surgery, your doctor will discuss revision options suitable for that procedure.
TORe Versus Lifestyle Support or Medication
TORe can treat anatomical issues, but nutrition care, physical activity, sleep, behavior support, and medication strategies can address other parts of weight management. These approaches are not competing choices. Your plan may include more than one, especially when several factors are contributing to your weight regain.
TORe Procedure Recovery Time
Recovery is usually much shorter than recovery after an abdominal operation. Mild nausea, a sore throat, stomach discomfort, or fatigue may occur for a few days. Many people return to desk work and light routines within several days. Your TORe procedure recovery time will depend on how you feel and what your job requires.
Your doctor will tell you when it is safe to drive and exercise, when you may lift heavier items, and when you may restart medicines. Follow the personalized treatment plan provided by your doctor.
Serious problems are uncommon, but they can happen. Risks include bleeding, infection, a hole in the digestive tract called a perforation, or stenosis, which is when the outlet becomes too narrow. Contact your treatment team if symptoms are severe, get worse, or do not match your recovery plan. The Johns Hopkins TORe overview gives a clear summary of side effects and risks.
Diet After the TORe Procedure
The diet after a TORe procedure protects the sutures while your outlet heals. Most plans start with liquids and then move to thicker liquids or pureed foods, followed by soft foods and regular textures. This process often lasts several weeks, but the timing and food choices can vary by person.
Your doctor may also provide guidance on hydration, protein, portion size, chewing, and separating food from drinks. Taking small sips and stopping when you feel full can help you adjust to the tighter outlet. Your doctor’s written plan should take priority because it reflects your procedure and specific health needs.

How Much Weight Can You Lose After a TORe Procedure?
There is no single result that applies to everyone. A review of 13 studies reported an average total body weight loss of 8.55% at 12 months. Other studies have reported lower or higher averages. Results can change depending on the technique, patient group, and follow-up program.
Longer-term results also vary. A five-year study of 331 patients reported averages of 8.5% at one year and 6.9% at three years. The average was 8.8% at five years. Some patients also received medication or another procedure.
These results are not guaranteed from TORe alone. Your starting weight, amount of regain, outlet size, eating pattern, health, and follow-up can all affect your results. TORe procedure success stories can be encouraging, but another person’s photos or pounds lost cannot predict your results. A useful story explains the timeline, starting point, follow-up care, and any other treatment used.
TORe Procedure Cost and Insurance
TORe procedure cost depends on the practice, facility, anesthesia, testing, and follow-up included in your specific plan. Insurance coverage also varies by insurer and policy. Some plans may require prior authorization or may not cover endoscopic revision for weight regain.
Before scheduling, ask for a written list of what is included and what may be billed separately. Ask your insurer if your plan covers the procedure, anesthesia, facility, and follow-up. For current Simmons MD program details, use the bariatric revision page.

FAQs
Is TORe the Same as Gastric Bypass Revision Surgery?
No. TORe is a type of gastric bypass revision, but it is not the same as traditional gastric bypass revision surgery. TORe is an endoscopic procedure performed through the mouth, so it does not require abdominal incisions. The doctor uses sutures to reduce an enlarged gastric outlet and may also tighten the stomach pouch, but TORe does not reroute the intestine or redo the original bypass.
How Much Weight Can You Lose After a TORe Procedure?
Studies report average total body weight loss in the mid-single digits to about 9% at one year. Your result may be different. Your specific anatomy, starting weight, follow-up, daily habits, and other treatments can all affect your results.
How Long Is the Recovery After TORe?
Many people resume light routines within several days, although recovery varies. You will usually follow a staged diet for several weeks while the outlet heals. Your doctor will give you a personal schedule for work, exercise, driving, and food.
Does Insurance Cover the TORe Procedure?
Some insurance plans may cover TORe. Others may exclude it or require prior authorization. Coverage depends on your policy, so confirm it with both the practice and your insurer.
