From beginning to end, the journey for our Long Island and Port Jefferson, NY patients undergoing bariatric care is full of changes. It will require persistence and discipline, but in the end it is all worth it. Feel free to learn more about the patient journey.

Weight Gain after Gastric Bypass Surgery

If you have had gastric bypass surgery in the past, and are now regaining the lost weight, it may be associated with changes in your stomach and intestine that make it possible to consume more food – and calories. A revision surgery may be necessary.

At New York Bariatric Group, our team of professionals is often called upon to perform gastric bypass revision surgery to assist those who are not experiencing the dramatic weight loss expected from gastric bypass surgery, or over time, are regaining the weight they lost after the surgery.

What Is Gastric Bypass Revision Surgery?

Some patients who have had gastric bypass surgery will slowly begin to regain weight. This may be the result of changes in how you eat, exercise, or as a result of pregnancy or other life changes. In other cases, the weight gain is the result of changes in anatomy – the stomach pouch has enlarged over time.

Gastric bypass revision surgery restores a smaller stomach size. In most cases, this surgery is performed laparoscopically.

Gained Weight After Gastric Bypass Surgery? We Can Help.

At New York Bariatric Group, we help those who are struggling with weight gain after undergoing gastric bypass surgery, or those who failed to lose weight as expected.

The first step in this procedure is a full health evaluation to determine the underlying cause of the weight gain or lack of results. The problem could be related to any of the following:

  • Dietary changes
  • Lack of exercise
  • Stomach pouch enlargement
  • Medical complications

If your increase in weight is the result of dietary changes or lack of exercise, these issues can be discussed in your medical evaluation at New York Bariatric Group. However, once the stomach pouch has enlarged, revision surgery may be the most effective option.

Inadequate Weight Loss After Gastric Bypass Surgery

A gastric bypass surgery may have resulted in complications preventing the expected weight loss. The size of the altered stomach pouch may have been left too large in the initial surgery. A range of other medical issues that could inhibit weight loss could be associated with diabetes medications that trigger the production of fat and cholesterol.

A full evaluation of your condition will reveal if you are a candidate for gastric bypass revision in NYC. Studies reveal that about 15 to 35 percent of patients who have undergone gastric bypass surgery start to regain weight over time. If this happened to you, revision surgery may be the answer that will get your health and body back on track.

Statistics on Bariatric Surgery Revisions In The USA

The American Society for Metabolic and Bariatric Surgery reports on the number of revision surgeries performed yearly. In the most recently reported year, 14.14 percent of the bariatric surgeries performed in America were revisions.

How is Gastric Bypass Revision Surgery Done?

At New York Bariatric Group, gastric bypass revision surgery can be performed endoscopically. A minimally invasive procedure called “laparoscopic distal Roux-en-Y” surgery has been designed to treat patients who are experiencing weight gain after undergoing gastric bypass surgery. This procedure involves altering the connections in the digestive tract so that less calorie absorption occurs, and significant weight loss is achieved.

What Are The Options For Gastric Bypass Revision Surgery?

The first step in determining what should be done in your case is a full evaluation of your health, and the specific conditions that have led to the failure to lose weight, or weight gain after gastric bypass surgery.

Once this medical evaluation has been performed, we can determine which procedure will be appropriate for you. As our team of bariatric surgeons has more experience with weight loss surgery than any practice in the state, you can be confident in our skills and your treatment.


Distal Roux-en-Y surgery can be performed if you have failed to achieve long term weight loss from a primary gastric bypass surgery.

In this procedure, the connections between the stomach and intestines are altered so that the food passes into the large intestine. Less intestinal tract will be available to process food and calories, and fat absorption is more thoroughly managed so that significant weight loss can be achieved.

Duodenal Switch

In this revision surgery, the duodenum, which is the first section of the small intestine, is surgically divided just after the outlet of the stomach structure. The “distal,” or last portion of the small intestine is then connected to the newly created stomach.

When you consume food, it will pass through a newly-created tubular stomach pouch, and then be emptied into the last segment of the small intestine. In this procedure, about three-fourths of the small intestine will be bypassed, leading to significant weight gain.


LABG, or “laparoscopically adjustable gastric banding,” involves placing an inflatable band around the top portion of the stomach, which is then inflated, compressing the stomach.

It separates the stomach into two sections, with a smaller upper stomach pouch, limiting the amount of food that can be comfortably consumed. The band is adjustable and can be altered to restrict more food if needed. The band may require adjustments over time, which are performed laparoscopically.

Another option is surgically tightening the connection between the stomach and the intestines so it restricts the quantity of food you can comfortably consume to correct stomach enlargement.

Am I A Candidate For Gastric Bypass Revision Surgery?

Candidates for gastric bypass revision surgery include:

  • Patients who see increased weight gain in the years following gastric bypass.
  • Patients who failed to lose the expected quantity of weight after gastric bypass surgery.
  • Patients who require closing a gastro-gastric fistula after bariatric surgery.

As with any surgical procedure, a full medical evaluation must be performed. At New York Bariatric Group, we adhere to very strict patient health and safety protocols and can evaluate your condition and advise you about the type of revision surgery appropriate to you.

Benefits Of Gastric Bypass Revision Surgery

The decision to undergo gastric bypass surgery is important and often stressful. If you have undergone the procedure, recovered from the surgery, and then discover that the surgical procedure was not effective, it can be very depressing. If you did achieve dramatic weight loss, and then slowly began to regain the weight you lost, action should be taken immediately, for your own health.

The benefits of gastric bypass revision surgery include:

  • The ability to maintain a healthy weight.
  • The expected weight loss from the initial surgery is now achieved.
  • Any problems, such as enlarged stomach pouch or dilated section between stomach and intestine corrected.
  • Complications such as an ulcer, hernia, or other complications can be successfully resolved.


Your recovery time will be based upon the type of revision surgery that was performed but is typically about two to three weeks. With laparoscopic surgery, the recovery time is about two weeks for most patients. Results with the Roux-en-Y technique have proven to be excellent.

Is It Covered By Insurance?

To determine whether your health insurance will cover the cost of revision surgery, we offer the assistance of our friendly, helpful staff.

Your health insurance company will want to know why the initial surgery failed – was it based upon a failed surgery, or a result of the patient failing to maintain a healthy weight due to excess food intake that caused the stomach pouch to stretch.

At NYBG, we will perform a full evaluation and assist with anything else that your insurance company might require.

What Are The Results Like?

The results of our gastric bypass revision surgery are excellent. If you had gastric bypass surgery in the past and failed to lose the expected amount of weight, or are regaining the weight you lost, we invite you to visit us at New York Bariatric Group to get answers.

The results of a revision surgery should lead to total success in your weight loss journey – but these procedures must be performed with the latest advances in bariatric surgery. At NYBG, we stay at the forefront of the latest developments in bariatric surgery and are recognized leaders in the field.

I was tired of the way I looked. I was tired of the way I felt.

I knew if I didn't change something soon, I was going to be in a lot of trouble. The consultation process was a lot easier than I expected. I was met with open arms. I was treated like I was the only patient here. Not only did they answer all of my questions, they had questions for me to make sure I was the right candidate for the surgery. After surgery and that weight started dropping off, my life started changing for the better.

Eileen's success story

It saved my life.

The driving factor behind me getting my procedure was that I couldn't get up off the floor with my granddaughter. That was my why. That was my big reason for having this surgery done. After surgery, it was a little bit of a struggle with what to eat. What you put in your mouth that you don't even think about. You don't think about what you're eating or how you're eating and portion size. It's what I do now every single day. The procedure has changed my life in so many ways. It saved my life.

I am totally comfortable in my own skin.

I think I always grew up identifying myself as less than other people because I was fat. I decided to tackle that and just live my life. I had a sleeve gastrectomy. It changed how I view myself.
