Gastric Bypass

Extreme obesity can seriously affect your health and self-esteem. If dieting and exercise aren't working, gastric bypass surgery can help.

This safe, effective procedure reduces your stomach size and restricts the calories your body absorbs. But the cost may be prohibitive.

ALO Bariatrics' certified surgeons in Tijuana, Mexico perform gastric bypass surgery in luxury facilities for much less than U.S. prices.

Benefits of Gastric Bypass Surgery

Suffering from extreme obesity can threaten your health, shorten your life expectancy, and make you feel unhappy about yourself and your appearance. Losing a significant amount of weight, thanks to bariatric surgery performed at ALO Bariatrics, can result in many life-changing benefits:

  • Lowers the risk of death from diseases like type 2 diabetes, cancer, and heart disease by up to 90 percent.
  • Improves your self-confidence and appearance.
  • Make routine activities easier.
  • Increases energy and reduces joint pain.
  • Makes life enjoyable again.

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

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

Four Frequently Asked Questions

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 Our 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.

Candidacy for Gastric Bypass

To qualify for bariatric surgery, you should meet the following requirements, not only for gastric bypass, but other procedures we perform such as gastric sleeve surgery.

Body Mass/Excess Weight

Have a body mass index of over 40 and more than 100 pounds of excess weight.

Body Mass/Chronic Disease

Have a body mass index over 35 and a chronic disease such as type 2 diabetes.

Exhausted Other Options

Dieting, exercise, or medication have failed to achieve long-term, significant weight loss.

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. We have offices conveniently located across the border in Tijuana, as well as in the beautiful vacation destinations of Guadalajara and Puerto Vallarta. We look forward to making your dream of a slimmer, healthier you become a reality.
