Gastric Bypass Weight Loss Surgery (Roux-en-Y)

The gastric bypass surgery, known as Roux-en-Y (RNY), is a procedure that alters the stomach as well as the digestive tract. Recognized as the “Gold Standard” of bariatric surgery, the gastric bypass promotes weight loss by separating your stomach to form a golf ball-sized pouch to reduce hunger and decrease food capacity. A portion of the small intestine is rerouted to speed up digestion and absorb fewer calories into the body.

Unlike diet and exercise, gastric bypass surgery is a fast and effective approach to fighting obesity as it reboots the body’s metabolic thermostat. According to our recent 2022 survey, patients lost an average of 92.8 lbs. one year after undergoing the bypass procedure.

Undergoing gastric bypass surgery in Mexico with our qualified surgeons is a smart play if you’re looking to have your surgery done in a full-service accredited hospital. MBC surgical teams have performed thousands of gastric bypass surgeries and have the experience to handle even the most atypical cases.

Benefits of RNY Gastric Bypass Surgery

Bypass surgery is a more effective bariatric surgery than lap-band and even gastric sleeve, with patients losing almost all of their excess weight within the first two years. Patients who are not ready to handle the life-altering aspect of the surgery are recommended to look into sleeve gastrectomy.

How Gastric Bypass Surgery Works

The RNY gastric bypass operation utilizes two methods to accomplish weight loss; Restriction and Malabsorption. Both components work cohesively together, so you achieve maximum weight reduction results while maintaining an obesity-free life. Anatomical alteration in RNY bypass changes the signals in the body causing decreased hunger and increased feeling of fullness after a meal. It also lightens digestion, and fewer calories are absorbed from the food.

We offer gastric bypass surgery in Tijuana, Mexico, with some of the most trusted, board-certified surgeons at the Mexico Bariatric Center®. Our top-quality surgeons perform RNY bypass procedures laparoscopically (minimally invasive). Undergoing gastric bypass surgery in Mexico with our qualified surgeons is a safe and right choice if you’re looking to have surgery done in a full-service, certified hospital that specializes in bariatric surgery. Our team has performed thousands of bypass surgeries, and we have the experience to handle even the most atypical cases.

Low Volume of Food Intake

Forming a small stomach pouch reduces the volume of food you can eat.

Changes Gut Hormones

Increases leptin hormone to feel satisfied after eating less food and fewer calories.

Absorb Less Nutrients

The small bowel reroutes food digestion to alter caloric and nutrient absorption.

Reduce Hunger Hormones

Appetite is suppressed from the lack of hunger hormones within the new stomach pouch.

Is RNY Bypass Right for Me?

Gastric bypass is better suited for patients with severe acid reflux and GERD. However, if you have ulcer problems or are taking Aspirin/Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) on a regular basis, gastric sleeve or duodenal switch are better options for you.

The reason is that there is no conventional routine to detect ulcers in the “stoma” or so-called “blind” stomach. Our surgeons review every patient’s health history thoroughly to determine if they could benefit from this weight loss procedure.

Surgical Steps of the RNY Gastric Bypass

The RNY gastric bypass procedure is performed laparoscopically, which is minimally invasive using 3 to 5 tiny incisions. The total length of time performing the operation is between 60 to 90 minutes from start to finish. You are required to stay in the hospital for one to two nights, however, to ensure fewer complications, the total hospital at Mexico Bariatric Center is 3 nights.

Healing is rather quick and recovery time may vary from patient to patient. In general, most patients return to work after two to four weeks following the surgery depending on your work environment and job duties. Upon request, we can fill out FMLA Paperwork (Family and Medical Leave Act) for your employer during your time off work.

Laparoscopic Incisions Minimal Invasive Icon

2. Cut 5-6 Laparoscopic Incisions

3. Abdomen Filled

The abdomen is inflated with carbon dioxide (CO2) gas for the surgeon to have room to maneuver with organs.

4. Stomach Pouch Formed

The stomach is divided up into two parts. One part is the size of a golf ball called the stoma and acts as the new stomach. Its larger counterpart, the remnant pouch, no longer receives food but helps with digestion by producing gastric juices.

Mini Gastric Bypass Icon Loop Intestine

5. Loop Bypass Small Bowel

The small intestine is re-arranged into a Y-configuration.  The upper small intestine (duodenum) is connected to a hole made in the stoma. The rerouting involves the bottom portion of the small intestine connecting to the jejunum, which is further down the intestinal tract.

6. Reinforce & Insert Drain

The staple line is strengthened with brand-name sutures, Johnson & Johnson or Covidien to control bleeding, stomach leakage, and stretching. A drain is inserted as a precaution for the early detection of a leak until the patient is released.

Is RNY Surgery Dangerous?

Gastric bypass surgery (RYGB) is a safe procedure but like any other surgery, it has short-term and long-term risks and side effects. Vitamin or iron deficiency along with protein or calorie malnutrition is common with RYGB because food intake bypasses a section of the intestines. Dumping Syndrome, for example, is also common after because food gets dumped directly from stomach to small intestine without being digested.[3]

Gastric Bypass Side Effects

  • Minor Side Effects: Body aches, feeling tired, feeling cold, dry skin, hair thinning and hair loss, mood changes[4]
  • Severe Side Effects: Pneumonia, Blood Clots, and Gallstones

Gastric Bypass Complications

  • Short-Term: Bleeding, Leakage (rate of .8%[5])
  • Near-Term: Stomach Obstruction, Stricture, or Abdominal Abscess
  • Long-Term: Delayed Leak, Malnutrition

Types of Gastric Bypass Surgery

Proximal Gastric Bypass, Distal Gastric Bypass, and Resectional Gastric Bypass:

  1. Proximal Bypass: Proximal or short-limb RNY is the standard procedure performed. The Y-connection is connected near the upper part (proximal) or the first 10 centimeters of the gastrointestinal tract (small intestine).
  2. Distal Bypass: In Distal Gastric Bypass or long-limb RNY, the Y-connection is connected further down the track about 100-cm (distal), allowing fewer nutrients to be absorbed. This increases the weight loss of the patient.

Gastric Bypass Revision Surgery in Mexico: Patients who have already undergone gastric bypass surgery can choose a laparoscopic or endoscopic (TORe) revision. This can arise because of many different issues, including lack of sufficient weight loss. MBC bariatric doctors are also experienced in the modification of gastric bypass surgeries previously done with an open incision. Learn more about gastric bypass revision in Mexico.
