Roux-en-Y Gastric Bypass Weight-Loss Surgery

Obesity is a chronic condition associated with the accumulation of excessive fat in the body. Obesity is designated with a Body Mass Index (BMI) of 30 and over. Gastric bypass surgery, also known as Roux-en-Y (RNY for short), is a bariatric procedure that helps slim down by changing how your stomach and small intestine handle the food you eat.

Gastric Bypass Surgery is recognized as the “Gold Standard” of bariatric surgery worldwide. It promotes weight loss by combining restrictive and malabsorptive components. The board-certified surgeon creates a tiny stomach pouch and then bypasses a portion of the digestive tracts.

Unlike diet and exercise, gastric bypass is a fast, powerful, and long-term solution to fighting obesity as it changes the body’s metabolic thermostat. Patients can lose over 78% of their excess body weight in 1.5 to 2 years after the operation.

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 less calorie is 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 Gastric 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.

Is Bypass 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

Gastric Bypass Surgical Procedure Steps

During the laparoscopic gastric bypass operation, the surgeon makes about 5 or 6 small incisions on the belly and inserts trocars (hollow tubes) through the incisions as a conduit for surgical instruments. The abdomen is inflated with carbon dioxide (CO2) gas for the surgeon to have room to maneuver with organs pushed aside gently.

laparoscope (probe equipped with a built-in camera) and other surgical instruments, including a retractor to lift the liver, can now be inserted into the abdominal cavity. The cutter/stapler (normally a product of Ethicon) is used to cut the stomach and staple the stomach at the same time.

Part One: Making a Small Pouch in the Stomach

The stomach is divided up into two parts by the stapler/cutter: a much smaller upper part (pouch) about the size of a golf ball and a larger lower part (remnant pouch). The new smaller stomach (called the stoma) holds about two ounces of food and receives food. The bottom part of the stomach (about forty ounces) no longer receives food – the gastric juices from this part pass into the intestine and mix with food.

Part Two: Making the Bypass

The surgeon divides the small intestine and re-arranges it into a Y-configuration. A half-inch hole is made in the new stomach pouch by electrocautery. Then the upper small intestine (the duodenum) is connected to the hole made in the stoma. The rerouting component is complete when the bottom portion of the small intestine is then connected (after bypassing) to the jejunum which is further down the intestinal tract.

Types of Gastric Bypass Surgery

  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 for the patient.

Gastric Bypass Revision Surgery in Mexico: Patients who have already undergone gastric bypass surgery can choose a laparoscopic or endoscopic 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.
