Gastric Bypass Surgery for Weight Loss

Gastric bypass surgery, also known as Roux-en-Y (RNY), is a bariatric surgery considered the “Gold Standard” for weight loss. The procedure involves altering the stomach and small intestine to create a small, golf ball-sized pouch in the stomach to reduce appetite and limit food intake. The small intestine is also rerouted to allow food to be digested more quickly and absorb fewer calories into the body.

Gastric bypass surgery is a highly effective method to combat obesity by promoting long-term weight loss and improving related health conditions such as diabetes and high blood pressure. In a recent MBC survey, patients who underwent gastric bypass in Mexico lost an average of 92.8 lbs. within one year. If you are struggling with obesity and have not succeeded with other weight loss methods, gastric bypass surgery in Mexico is well worth considering.

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. The superiority of gastric bypass is due to the shifts in ghrelin, gut hormones, and GLP-1.

Anatomical modifications in RYGB change the signals in the body, causing decreased hunger and increased feelings of fullness after a meal. It also lightens digestion, and fewer calories are absorbed from the food.

Do I Qualify for Gastric Bypass?

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) regularly, 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 thoroughly review every patient’s health history to determine if they could benefit from this weight loss procedure.

Costs and Pricing for Gastric Bypass Surgery

RNY bypass is a permanent weight loss procedure more effective than Vertical Sleeve Gastrectomy (VSG) and safer than duodenal switch surgery. Patients crossing the border to seek out affordable weight loss surgery can save 70% with Mexico Bariatric Center!

The fees of undergoing gastric bypass surgery in the United States can be pretty expensive, with an average cost of $23,000, due to the high cost of healthcare. Patients without insurance opt to go abroad to receive RNY bypass to get top-quality care at attractive prices.

Compared to other countries, Mexico offers one of the lowest average costs for the RNY gastric bypass, around $6,395. Our all-inclusive packages start at only $5,895*.

Benefits of Gastric Bypass Surgery

Gastric bypass surgery can be a superior obesity treatment and can lead to improvements in obesity-related health conditions such as:

  • Type II diabetes (T2DM): Gastric bypass has been shown to improve blood sugar control and can even lead to the complete resolution of diabetes in some cases.

  • High blood pressure: Losing excess weight through gastric bypass surgery can lead to lower blood pressure and a reduced risk of heart disease.

  • Sleep apnea: Losing weight can help improve breathing during sleep and reduce the severity of sleep apnea.

  • Gastroesophageal reflux disease (GERD): Gastric bypass surgery can help diminish or alleviate the frequency and severity of acid reflux and GERD.

  • Cardiovascular disease: Losing excess weight through gastric bypass surgery can lower the risk of heart attack and stroke.

  • Polycystic ovary syndrome (PCOS): Reducing body mass has a significant boost in fertility especially with women who have PCOS prior to surgery experience higher reproduction rates after surgery.

Surgical Steps of the RNY Gastric Bypass

The RNY gastric bypass procedure is performed laparoscopically (minimally invasive) using 3 to 5 tiny incisions. The total time in the operation is between 60 to 90 minutes from start to finish. You must stay in the hospital for one to two nights; however, to ensure fewer difficulties, the total hospital at Mexico Bariatric Center is three 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 their 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.

Anesthisia Icon

1. Anesthesia Administered

General anesthesia is administered by the anesthesiologist and a breathing tube (endotracheal tube) is inserted into the esophagus.

Laparoscopic Incisions Minimal Invasive Icon

2. Cut 5-6 Laparoscopic Incisions

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.

Trocars Gastric Sleeve Icon

3. Abdomen Filled

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

Reinforced Gastric Sleeve Staple Suture Icon

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.

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 Gastric Bypass Dangerous?

Gastric bypass surgery (RYGB) is a safe procedure, but like any other surgery, it has short-term and long-term risks. Vitamin deficiency and malnutrition are common with RYGB because food bypasses a section of the intestines. Dumping syndrome, is common because food gets dumped from the stomach to the small intestine without being fully digested.3

Potential Side Effects

  • Minor Side Effects: Body aches, feeling tired, feeling cold, dry skin, hair thinning and hair loss, mood changes4
  • Severe Side Effects: Pneumonia, Blood Clots, and Gallstones

Gastric Bypass Complications

  • Short-Term: Bleeding, Leakage (0.8%)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.
  3. Resectional Gastric Bypass: Laparoscopic resectional gastric bypass for morbidly obese patients performs distal gastrectomy of the excluded stomach. This surgical treatment presents very similar results compared to classical RNY gastric bypass.

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 from many issues, including insufficient weight loss. MBC bariatric doctors are also experienced in modifying gastric bypass surgeries previously done with an open incision. Learn more about gastric bypass revision in Mexico.
