What is a Gastric Bypass Surgery By Gerald Witt on January 24, 2023

what is gastric bypass surgery

Gastric bypass, sometimes referred to as Roux-en-Y (roo-en-wy) gastric bypass, is a type of weight-loss procedure that entails creating a tiny pouch out of the stomach, removing about a meter and a half of the small intestine and then attaching the small intestine directly to this new pouch. If you've had a gastric bypass, your stomach and the beginning section of your small intestine will no longer be involved in the digestion of food. Instead, everything you eat will enter a much smaller pouch in your stomach and then move directly into your small intestine.  This will cause what is known as malabsorption and will help you with weight loss because the body will not absorb the food and calories you eat.  Weight Loss Team, the Bariatric Surgical Center at the CMQ Riviera Nayarit Hospital in Puerto Vallarta Mexico performs Gastric Bypass surgery in Mexico on a routine basis.

One of the most popular procedures for bariatric surgery is gastric bypass. The gastric bypass procedure is used when diet and exercise have failed or when you are experiencing major health issues as a result of your weight.

For Whom it is Intended

A gastric bypass or other surgical methods of weight loss may be appropriate if the patient meets the following conditions:

  • If your body mass index is 40 or greater, you are overweight (extreme obesity).
  • Your body mass index (BMI) is between 35 and 39.9 (obese), and you suffer from a weight-related health condition such as type 2 diabetes, high blood pressure, or severe sleep apnea. If you have a body mass index between 30 and 34 and severe weight-related health concerns, you may be eligible for weight-loss surgery.

However, gastric bypass in Mexico is not appropriate for everyone who is exceedingly overweight. For weight-loss surgery to be an option for you, you might need to meet specific medical requirements. To determine whether you qualify, you'll probably go through a rigorous screening process. A permanent lifestyle shift is required if you want to improve your health and well-being. You may be required to participate in a long-term monitoring program that addresses your medical needs as well as your dietary, lifestyle, and behavioral habits.

To find out if the gastric bypass is right for you, you should enquire with your local bariatric surgeon.  Gastric Bypass surgery in Mexico is a great option to help patients lose 100 or more pounds.

What to Expect

Hospitals perform gastric bypass surgeries. Your hospital stay could be longer or shorter depending on how well you recuperate.  Typically, most gastric bypass patients will stay 2 nights in the hospital.

During the procedure

Before your procedure, you will receive a general anesthetic. Anesthesia is a medication that keeps you relaxed and drowsy throughout the operation.  General Anesthesia will have you asleep for the entire 2–3-hour procedure.

The particulars of your gastric bypass procedure rely on your unique circumstances and the doctor's methods. Some operations require the standard large (open) abdominal incisions. However, the majority are done laparoscopically, which entails inserting tools through numerous tiny abdominal incisions.  In Puerto Vallarta and at Weight Loss Team their special technique also at times allows for a 4-incision laparoscopic gastric bypass surgery.

Following the open or laparoscopic incisions, the surgeon makes a cut across the top of your stomach to seal it off from the remainder of your stomach. The resulting pouch is small and can only accommodate two to three ounces or so of food. Your normal stomach can typically accommodate roughly 3 quarts of food.

The surgeon will then remove a portion of the small intestine and suture it directly into the pouch. Food is subsequently passed through this tiny stomach pouch and into the small intestine that is attached to it. Food reaches the middle portion of your small intestine without passing through the majority of your stomach or the initial part of your small intestine.

Typically, surgery lasts a few hours. Immediately following surgery, you are checked over by medical personnel in a recovery room.

After the procedure

As your stomach and intestines start to recover following gastric bypass surgery, you should only consume liquids for the first few days after surgery. You will then adhere to a particular eating regimen that gradually transitions from liquids to pureed foods. Once your body is able to accept firmer foods, you can next start eating soft foods.

How much and what you are allowed to eat and drink may be subject to a variety of limitations. In addition to a multivitamin including iron, calcium, and vitamin B-12, your doctor may advise you to take vitamin and mineral supplements following surgery.

During the initial months following weight-loss surgery, you will also undergo routine medical exams to track your health. Various exams, bloodwork, and laboratory tests may be required.

In the first three to six months following a gastric bypass in Puerto Vallarta, you can notice changes as your body adjusts to the quick weight loss, such as:


  • Dry skin
  • Thinning hair
  • Mood swings
  • Fatigue that makes you feel like you have the flu

Recovery Time

Before you feel ready to return to work, you'll normally spend two nights resting in the hospital and a few days recovering at home. It could be necessary to refrain from vigorous activity for up to six weeks, and it might take up to twelve weeks to start eating normally again.

Advantages of Gastric Bypass Surgery Besides Weight Loss

Long-Term Remission for Type 2 Diabetes.

According to one study, type 2 diabetes can be permanently cured with bariatric surgery. The outcomes of this study demonstrate that the operation is very successful in treating obese people with type 2 diabetes, with almost all patients remaining off of insulin and other related drugs for at least three years following surgery.

Improved Cardiovascular Health

Weight reduction surgery has been shown to lessen the risk of cardiovascular diseases and peripheral vascular disease. One study even suggests that the procedure's associated weight loss surgery in Mexico can mitigate the dangers of cardiovascular disease, cerebrovascular disease, and high blood pressure. Following surgery, blood pressure and cholesterol levels can go back to normal or almost normal, lowering these risks and enhancing general health.

Relief of Depression

Because of their negative self-image and societal shame, many obese persons experience depression. Even younger individuals with significant excess weight find it challenging to engage in activities they might otherwise enjoy, which can result in social isolation and despair. Losing this extra weight can help these patients' emotional wellness. Bariatric surgery patients were shown to have a 32.7% reduction in depression at the time of surgery and a 16.5% reduction six to twelve months later.

Cut Back on Obstructive Sleep Apnea

People with sleep apnea can frequently quit using a CPAP machine at nighttime after they reach and maintain a normal weight range. One year following surgery, 80 to 85% of patients report that their sleep apnea has completely disappeared.

Joint Pain Relief

A lot of stress is placed on your weight-bearing joints when you carry around excess weight, which frequently results in chronic pain and joint degeneration. The large and long-lasting weight loss that follows bariatric surgery reduces the strain on joints, frequently allowing people to stop taking painkillers and enjoying much more mobility.

Improve Fertility

During the childbearing years, weight loss surgery in Puerto Vallarta can potentially increase fertility. According to one study, bariatric surgery can help women who don't ovulate have better menstrual cycles and reduce their chance of miscarriage.

Risks of Gastric Bypass Surgery

•Pouch stretching is a danger for those who have had gastric bypass surgery. Over time, the stomach grows larger and stretches allowing the patient to eat too much food.

•A leak upon the staple line.

•Deficits in vitamins, minerals, and nutrition. Your body will have a harder time absorbing nutrients from food.

•Stenosis of the stoma, also known as stricture. An obstruction that develops from scar tissue, at the point where the stomach and small intestine meet can lead to nausea, vomiting, reflux, and ultimately the inability to eat. There will be a need to dilate this.

Final Thoughts

Although it requires a substantial lifetime commitment, gastric bypass surgery can result in profound long-term effects. Surgery may make these improvements work for you like never before if you're willing to take more intensive care of yourself, eating more thoughtfully, and exercising frequently.  Having Gastric Bypass surgery in Puerto Vallarta Mexico with Weight Loss Team is a viable option for patients looking to save up to 70% off US prices, or for Canadians looking to jump the waitlist and get the surgery done.  At $6200usd the Gastric Bypass in Mexico is very affordable, and a safe option that provides excellent results.
