Gastric Bypass Surgery - Jet Medical TourismChoosing gastric bypass surgery with our board-certified surgeons is an excellent surgical option for those people who want to travel abroad for affordable weight loss surgery.

Gastric bypass surgery, also known as roux-en-y gastric bypass is widely considered the “gold standard” and most common weight loss surgery worldwide.

Gastric bypass is a type of weight loss surgery that makes changes to your digestive tract to help you lose weight by limiting food intake or by reducing the absorption of nutrients, or both.

Gastric bypass surgery is typically done when conventional methods of weight loss such as diet and exercise haven’t worked or you have serious health problems related to obesity. In fact, studies show that gastric bypass is effective at resolving many obesity-related diseases such as diabetes, high blood pressure, high cholesterol, sleep apnea and low back pain.

Weight Loss After Gastric Bypass Surgery

Undergoing gastric bypass surgery may help you with weight loss, which varies across patients because everyone has a different body mass index (BMI) due to different heights and weights. On average, you can expect:

  • Gastric bypass patients lose about 70% of their excess body weight after surgery (first 24 months).
  • Studies show gastric bypass patients are able to keep > 61% of the excess body weight off for up to 20 years.


Health Benefits of Gastric Bypass Surgery

Gastric bypass surgery has been shown to be a highly effective method of achieving weight loss, resulting in significant improvement or resolution of obesity-related comorbidities. In fact, clinical studies show that gastric bypass resolved Type 2 diabetes in 76.8 percent of patients, resolved high blood pressure in 61.7 percent of patients and reduced high cholesterol in 70-95 percent of patients.

If you are affected by obesity-related conditions, having gastric bypass surgery may help you.

How Roux-en-Y Gastric Bypass Surgery Works

Roux-en-Y gastric bypass shortens the digestive process and reduces the body’s ability to absorb calories from food. Roux-en-Y is done in two parts.

Part One: Create a Small Pouch in the Stomach

  • The bariatric surgeon will divide the stomach into a large portion, and a much smaller portion called the gastric pouch.
  • The smaller upper pouch is about the size of an egg (approximately one ounce in volume) and will hold significantly less food.
  • The larger bottom pouch (bypassed portion of the stomach) is closed and divided from the new gastric pouch.
  • The new gastric pouch restricts the amount of food it holds so you eat less and feel full quickly.
  • This “restrictive” procedure promotes rapid weight loss.


Part Two: The Roux-en-Y Gastric Bypass

  • The bariatric surgeon detaches the gastric pouch from the first part of the small intestine (Duodenum) and reconnects it to a part of the small intestine further down (Jejunum).
  • Food will then travel from the new gastric pouch into the Jejunum and completely bypass the upper portion of the small intestine.
  • Bypassing part of the small intestine limits the absorption of calories.
  • This form of stomach surgery is called a “Roux-en-Y“.


How Gastric Bypass Surgery is Performed

Gastric bypass surgery is done when traditional methods of weight loss such as diet and exercise haven’t been successful or when you have serious medical problems because of your weight. Gastric bypass can be performed through open surgery or laparoscopic surgery, which is a minimally invasive procedure.

Most surgeons prefer laparoscopic gastric bypass because it results in smaller incisions and less pain compared to the open procedure.

3 Types of Gastric Bypass Surgery

There are 3 types of gastric bypass surgery. Each procedure is performed in nearly the same manner with small variations.

  1. Gastric Bypass Roux-en-Y (proximal) is the most common procedure used today. The Y-intersection is formed near the upper (proximal) end of the small intestine. The Roux limb is constructed using about 31 to 59 inches of the small intestine. This preserves the rest of the small intestine for “absorbing nutrients”.
  2. Gastric Bypass Roux-en-Y (distal) is where the Y-connection is formed much closer to the lower (distal) end of the small intestine. Because of the closer distance, its causes reduced absorption of calories: primarily of fats and starches, but also of various minerals and the fat-soluble vitamins.
  3. Mini-Gastric Bypass Surgery creates a long narrow tube of the stomach along its right border. A loop of the small gut is brought up and hooked to this tube at about 180 cms from the start of the intestine.

How Gastric Bypass Causes Weight Loss

Roux-en-Y gastric bypass surgery is classified as a “restrictive” and “malabsorptive” operation that causes weight loss through two primary methods.

  • First – stomach capacity is reduced by up to 85% of its original size. This causes weight loss by restricting the amount of food eaten at one time.
  • Second – a portion of the upper small intestine is bypassed. This means food flows from the new gastric pouch directly into the middle section of your small intestine (jejunum). Bypassing the upper small intestine (duoenum); the part that absorbs most of the calories from food causes patients to lose even more fat.
How Science Works. The small intestine plays an important role in weight loss. It communicates with the brain via hormones, and nerve signals that send messages about calorie levels and nutrient content of food. When the brain receives this information, it responds by causing you to feel full. Your brain then manages the activities in various tissues (multiple tissue types form organs and body structures) to make sure the nutrients get handled properly. That’s why dietary changes and life-long vitamin and mineral supplementation are required after gastric bypass surgery.


Am I a Candidate for Gastric Bypass?

Qualifications for bariatric surgery in most cases include:

  • You have a body mass index (BMI) > 30
  • You are more than 100 pound over your ideal body weight
  • You have attempted to lose weight with diet and exercise, but were not successful
  • You have a body mass index > 29 and suffer from negative health conditions related to obesity such as high blood pressure or diabetes


Benefits of Gastric Bypass Surgery

Research supports the benefits of gastric bypass surgery in respect to treating morbid obesity. People who have lived with obesity for years, know that the disease has a severe negative impact on the quality of life. As a result, obesity may affect your self-esteem, confidence and prevent you from participating in certain activities.

Studies show that morbid obesity not only affects the quality of your life, but also affects the length of your life. It has been linked to serious and life-threatening diseases such as type 2 diabetes, heart disease, high blood pressure, heartburn and cancer, to name a few.

Roux-en-Y gastric bypass may offer you a whole new outlook on life…

  • Research shows that gastric bypass surgery produces significant long term weight loss, averaging 60 to 80% of your excess body weight.
  • Proven long term effectiveness – studies show that after 10 to 14 years, gastric bypass patients still maintain 50 to 60% excess weight loss.
  • Medical problems related to obesity such as type 2 diabetes, high blood pressure and high cholesterol, sleep apnea, heartburn (gastroesophageal reflux disease) and depression are improved or eliminated after gastric bypass surgery.

Gastric Bypass Surgery Pre Op Diet

Gastric bypass is only a tool to help promote weight loss and a part of the overall treatment. The “most critical” part of losing weight and keeping it off is your commitment to adopting new eating and lifestyle habits. A healthy pre-op, gastric bypass diet will prepare you.

Gastric Bypass Surgery Post Op Diet

One of the most important parts of gastric bypass is learning new eating habits. You must learn how to modify your eating behavior, if you want to be successful at losing weight. Your commitment to a gastric bypass post op diet will dramatically increase your chances for achieving long-term, weight loss.

Gastric Bypass Surgery Side Effects

Most patients who undergo gastric bypass will experience side effects such as nausea, vomiting or constipation. Some patients may experience food intolerance and that is where our nutrition and dietary experts can help you avoid problematic foods.

Gastric Bypass Surgery Complications, Risks

People who have gastric bypass and abdominal surgery are vulnerable to certain risks and complications. Although these problems rarely occur, it’s important that you know the facts, evaluate all options and determine if the benefits of weight loss surgery outweigh the risks in your specific case.
