Roux-en-y gastric bypass is a type of weight-loss surgery that involves creating a small pouch from the stomach and connecting the newly created pouch directly to the small intestine. After gastric bypass, swallowed food will go into this small pouch of stomach and then directly into the small intestine, thereby bypassing most of your stomach and the first section of your small intestine.

What is Gastric Bypass Surgery?

The second most common weight loss surgery performed is the roux-en-y gastric bypass. According to the American Society for Metabolic and Bariatric Surgery, the sleeve gastrectomy accounts for 18% of all weight loss surgeries that are performed.

The gastric bypass is a surgery that is performed laparoscopically. This type of surgery uses small incisions instead of one large incision. During surgery, a small stomach pouch is created. The new stomach, or pouch, is about the shape and size of an egg. This part of the surgery restricts the amount of food that can be consumed. Next, the small intestine is divided. One end is attached to the new pouch, while the other end is attached further down on the small intestine. This part of the surgery diverts some of the food you eat, which results in less digestion of food.

On average, many patients can expect to lose between 60-70% of their extra weight. After weight loss surgery, many weight related health conditions, such as diabetes, high blood pressure, and sleep apnea, completely resolve or are significantly improved. Patients also report more confidence and vitality and are pleased to be able to engage in more activities. More than 90% of patients are able to maintain the weight loss long term.

How long does the operation take and how fast is the recovery?

A gastric bypass takes about 2-4 hours to complete and usually involves a 2-3 night stay in the hospital.

The recovery is fairly quick. Patients are up walking the day of surgery.  Pain is controlled with pain blocks and medications. Many patients can go back to work after a few weeks, depending on their recovery. No heavy lifting will be suggested for one month after surgery.

Is there any special follow up required?

Ongoing follow-up with our team is what allows patients to achieve good results with fewer complications. It is very important to have routine testing of the vitamin levels in your body to make sure that you are getting the vitamins and nutrients you need.

Gastric bypass is one of the most common types of bariatric surgery in the United States. Gastric bypass is done when diet and exercise haven't worked or when you have serious health problems because of your weight.

  • The surgeon begins by creating a small pouch by dividing the upper end of the stomach.
  • The stomach is about the size of an egg, and restricts the food intake.
  • Then a section of the small intestine is attached to the pouch to allow food to bypass the duodenum, as well as the first part of the jejunum.
  • The small intestine is reconnected 150 centimeters from the pouch to allow ingested food and digestive enzymes to mix.
  • This is a restrictive and malabsorptive procedure.
  • This gives the food less time to digest and less time for the calories and nutrients to be absorbed into your system.
  • Typical hospital stay is 2 to 4 days.

Exploring the Benefits

Gastric Bypass Surgery has many benefits including:

  • Most patients will lose about 60 to 80% of their excess body weight.
  • This procedure can resolve GERD (need to spell this out, what is it?).
  • It does not require the implantation of a foreign body, such as a gastric band.
  • The procedure mechanically decreases the size of the stomach but also decreases the secretion of the hormone ghrelin, which results in the feeling of satiety (fullness) sooner.
  • The procedure can also improve weight-related medical conditions.
