RNY Gastric Bypass Surgery in Mexico

Gastric bypass surgery, known as Roux-en-Y (RNY), is the “Gold Standard” among bariatric procedures. Gastric bypass surgery stands out as a powerful weapon in the fight against obesity, showing remarkable success in achieving sustained weight loss and alleviating obesity-related health issues like diabetes and high blood pressure.

Recent findings from an MBC survey reveal that individuals who underwent gastric bypass surgery in Mexico experienced an astounding average weight loss of 92.8 lbs. within just one year.

This transformative surgery involves dividing the stomach to create a small, golf ball-sized pouch and rerouting the small intestine. The RNY gastric bypass not only curbs appetite and restricts food intake, but it also reduces fat absorption, paving the way for effective weight management.

Mexico has emerged as a promising destination for individuals seeking this life-changing surgery.

If you’ve struggled to overcome obesity and its associated health concerns, exploring the option of Mexico gastric bypass with MBC could be a constructive step toward a healthier, more fulfilling life.

How Gastric Bypass Surgery Works

The RNY gastric bypass is distinctive for its dual approach, effectively addressing weight loss through both restriction and malabsorption mechanisms. By employing these two methods synergistically, you can achieve optimal weight reduction outcomes, setting the stage for a healthier future devoid of obesity-related challenges.

Neurohormonal Regulation of Energy Intake

RNY gastric bypass triggers a shift in bodily metabolic signals through anatomical modifications. Metabolic reset leads to increased leptin production and decreased ghrelin levels, which means reduced hunger sensations and an amplified sense of fullness after meals. This transformational effect not only curbs your appetite but also supports enhanced digestion, resulting in the absorption of fewer calories from the food you consume.

RNY bypass operation has little effect on Ghrelin and CCK but increases GLP-1 and PYY. GIP levels, however, decreased significantly in obese people, especially in diabetic patients.

How Much Weight Do I Lose with Gastric Bypass?

According to Obesity Action, on average, patients have lost approximately 34 percent of their total body weight [1] within the first year after gastric bypass surgery. A majority lose almost all of their excess weight (averaging 70-80% Excess Weight Loss %EWL) within the first two years.
The gastric bypass weight loss chart is estimated to be;

  • 3 months: 35% excess weight loss**
  • 6 months: 55% excess weight loss**
  • 12 months: 72% excess weight loss**
  • 18 months: 78% excess weight loss**

These numbers are average and people can lose up to 100% of their extra body fat and get to their body's ideal weight or goal weight. Success can be achieved by setting proper expectations, following up the diet instructions, changing your habits, and sticking to them.

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.

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) 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.

Do I Qualify for Gastric Bypass?

Here are the criteria for gastric bypass candidacy,

  • BMI of 35+ or with comorbidities
  • Ages between 16 and 65 (case by case basis)
  • Realistic weight loss expectations

Cost of Gastric Bypass in Mexico

RNY bypass is a permanent weight loss procedure more effective than Vertical Sleeve Gastrectomy (VSG) and safer than duodenal switch surgery. 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. Crossing the border to seek affordable weight loss surgery can save you up to 70%!

Compared to other countries, Mexico offers one of the lowest average costs for the RNY gastric bypass, around $6,395. Our all-inclusive packages  at MBC starts from $5,595*.

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.

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 Gastric Bypass Dangerous?

Gastric bypass surgery (RYGB) is a safe procedure, but like any other surgery, it has short-term and long-term dangers. 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, Anastomotic Leakage (0.8%)5
  • Near-Term: Stomach Obstruction, Stricture, or Abdominal Abscess
  • Long-Term: Delayed Leak, Malnutrition, Peptic Ulcer

Types of Gastric Bypass Surgery

RNY Gastric Bypass Average Monthly Weight Loss (Real Patients 2021-2022)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 patient's weight loss.
  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.

Anticolic and Retrocolic gastric gastric bypass

  • Anti-colic anti gastric bypass - If roux limb is anterior to the remnant stomach and the transverse colon.
  • Retro-colic retro gastric bypass - If gastric pouch and roux limb is posterior to the remnant stomach.

Gastric Bypass Revision Surgery in Mexico: Patients who have already received gastric bypass surgery can choose a laparoscopic and 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 Mexican gastric bypass revision.
