Gastric Bypass Surgery for Weight Loss
Are you considering weight loss solutions that can bring about lasting results? Gastric bypass surgery, known as Roux-en-Y (RNY), is the “Gold Standard” among bariatric procedures. This transformative surgery involves reshaping the stomach and rerouting the small intestine to create a small, golf ball-sized pouch within the stomach. The RNY gastric bypass not only curbs appetite but also restricts food intake, paving the way for effective weight management.
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.
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 gastric bypass surgery in Mexico could be a transformative step toward a healthier, more fulfilling life.

How Gastric Bypass Surgery Works
The RNY gastric bypass surgery stands out 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.
What sets the RNY gastric bypass apart is its profound influence on key factors like ghrelin, gut hormones, and GLP-1. Through anatomical modifications, this procedure triggers a shift in these bodily signals, leading to a reduction in 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.

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**

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.

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:

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.

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:
- 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).
- 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.
- 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.
