About Gastric Bypass Surgery (aka Roux-en-Y)

Gastric bypass is one of the most effective and well-known types of bariatric surgery procedures performed at our offices in Tijuana, Puerto Vallarta, and Guadalajara. It can provide obese patients with dramatic weight loss. Roux-en-Y weight loss surgery at ALO Bariatrics consists of three steps:
...you will be asleep and pain free during the procedure.

Day of Procedure

...you will be asleep and pain free during the procedure.
General anesthesia will be administered by one of our experienced and certified anesthesiologists so you will be asleep and pain free during the procedure. 
Your surgeon will divide your stomach into small and large sections. Medical-grade staples will be used to close and reinforce the smaller section, creating a stomach pouch about the size of a walnut. This newly created stomach pouch will hold about one ounce of food. A normal stomach holds around three pints.
Finally, most of your small intestine will be removed. The remaining section of small intestine will be attached to your stomach pouch. This is the bypass part of the surgery. Food will now go into the small pouch, bypassing the larger section of your stomach and then pass directly into your shortened small intestine for digestion.
After surgery, you will be monitored closely in the hospital by our caring and highly trained medical staff before being discharged to your complimentary hotel room in a day or two.

Take a Closer Look at Gastric Bypass Surgery

Gastric bypass, also known as Roux-en-Y, was named after surgeon César Roux and the Y-shaped stomach pouch created during surgery.

Gastric Bypass vs. Gastric Sleeve

Gastric sleeve surgery, also known as sleeve gastrectomy, is another effective weight loss surgery option that may be recommended. Both gastric sleeve and gastric bypass surgery reduce the size of your stomach to provide dramatic weight loss results for obese patients, but the surgeries themselves have some important differences:

  • Unlike gastric bypass, gastric sleeve surgery does not involve attaching your small intestine to a stomach pouch. 
  • Instead, about 80 percent of your stomach is removed laparoscopically, leaving a gastric sleeve about the size and shape of a banana. The gastric sleeve holds much less food than your full-sized stomach, resulting in dramatic, long-term weight loss.
  • During your consultation, your surgeon can discuss if a sleeve gastrectomy or gastric bypass is the best option for you.

Ready to Live a Healthier Life?

Whether you live in nearby San Diego or outside of the United States, ALO Bariatrics is here to provide you with superior, safe, and effective gastric bypass surgery at a fraction of the cost in the U.S. We have offices conveniently located across the border in Tijuana, as well as in the beautiful vacation destinations of Guadalajara and Puerto Vallarta.

Five Frequently Asked Questions

Is Gastric Bypass Surgery Painful?

No. General anesthesia is administered during gastric bypass surgery to ensure patients are not conscious and are free from pain while the stomach, small intestine, and other organs are adjusted and rerouted. After the gastric bypass is completed, patients may experience some soreness and discomfort. This is a normal temporary side effect. We provide pain medication and detailed instructions to keep your post-op pain to a minimum.

How Do I Start Losing Weight?

Since your stomach is now smaller, you will feel fuller much faster when you eat. This helps the weight loss process. The Roux-en-Y procedure also decreases the calories that your small intestine absorbs, another important weight loss factor.

How Much Weight Will I Lose?

Every bariatric surgery patient responds differentially, as factors like lifestyle habits and the type of weight loss surgery you had can affect your long-term weight loss. On average, severely obese gastric bypass patients can lose half their body weight or more over a two-year period.

Where Were Your Surgeons Trained?

Our board-certified bariatric surgeons have received specialized training at the most prestigious medical schools and hospitals in Mexico as well as the United States, including the National Institute of Medical Sciences and Nutrition and Cook County Hospital in Chicago.

What Is Recovery Like?

You will be monitored closely during your two- to three-day hospital stay and will have follow-up appointments at our offices in Tijuana, Puerto Vallarta, or Guadalajara before you are cleared to go home. You'll be given prescription medications for pain. Most patients are completely healed and pain-free in three to five weeks.
