Patient Journey

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.
