Gastric Bypass Procedure

We perform Laparoscopic Gastric Bypass Surgery, specifically the Roux-en-Y technique (RGB) – worldwide, the most popular bariatric procedure.

The procedure is performed using several small abdominal incisions, into which a laparascopic camera is inserted along with other specialized operating instruments.

During the procedure, the surgeon staples the upper (smaller) part of the stomach, separating it from the lower (larger) part. The small intestine is then rerouted but remains connected to both pouches.

The main connection (the Roux limb), redirects food from the newly created upper pouch to the small intestine (the duodenum).

Stomach pouch volume is radically reduced resulting in lower caloric absorption, a rapid feeling of satiety, and weight reduction. The upper stomach pouch is first formed at a rather small capacity of 15-20cc. After 6-12 months the stomach pouch will gradually expand. Most patients arrive at a meal capacity of 3-7 ounces.

Expressed as a percentage of excess weight, the amount of weight reduction generally ranges from 30 to 70 percent after 5 years, Since weight loss can stop or even reverse after some time, patients must pay close attention to changing their lifestyle in assure permanent results

Overall, bariatric surgery patients can live longer and healthier lives, including a reduction in risk for metabolic and cardiovascular disease, Type 2 diabetes, hypertension, high cholesterol, sleep apnea and depression.

Typical candidates for gastric bypass are people who remain chronically overweight after traditional strategies, such as diet and exercise, have failed. Particularly appropriate are patients suffering from an obesity-related disease such as diabetes or hypertension. Such patients are most in need of an effective solution to their weight control problems.

To be eligible for bariatric surgery you must be medically obese with a BMI within the past 2 years of at least 35. You may also qualify for the procedure with a BMI of slightly less than 35 if other serious medical conditions, such as diabetes, cardiovascular disease, hypertension, or sleep apnea, are present. The prospective patient should keep in mind that this is major surgery with all its inherent risks.

While there are enormous benefits to gastric bypass surgery, such as a loss of excess weight and improvements in weight related ailments, the procedure is irreversible and will require significant lifestyle and behavioral changes. It’s not a path for everyone, however it is a powerful weapon against chronic obesity offering hope for millions looking for a longer, healthier, and happier life.


Will I lose a lot of weight?
Gastric Bypass is the most effective of all bariatric surgery options. While all patients are different, our results show around 70-80% excess weight loss during the first twelve months following surgery.

Can Gastric Bypass fail?
It’s rare, but occasionally it happens. Mostly it was a failure to adhere to maintain lower caloric intake, or consistently eating the wrong kind of food combined with a sedentary lifestyle.

Will the scar/scars disappear afterwards?
If you have had laparoscopic surgery then unless you are susceptible to keloid formation, the the incisions will be small and will quickly fade.

How much time will I need to be away from work?
This depends on the type of job specifically the amount of physical activity required. Heavy manual labor jobs can mean a month or more away from work. Shorter recover times, of 2-3 weeks will be enough for less demanding jobs. In any case your stomach will be sensitive for up to 2 months so you must avoid any activity that puts unnecessary strain to that area.

Do I have to eat certain foods?
Well certainly you must adhere to a sensible diet and remember that how much you eat is as important at what you eat. Sugary foods can increase risk of Dumping syndrome so be sure to choose fruit if you have cravings for sweets. Our nutritional specialist will god into great detail with you about what you can and cannot eat – her advice is valuable and to be followed.

Will I be able to be pregnant after Gastric Bypass surgery?
Due to the considerable metabolic and hormonal stress that Gastric Bypass surgery applies to the female body we suggest that that you postpone any pregnancy plans for min 1 year.


Bariatric surgery requires you adopt new habits about food. You will need to commit to dietary guidelines and limits set by our nutritional expert.

Reduced portions are an essential part of that program and will come naturally as your desire and interest in food diminishes. Your new smaller stomach will hold less food. After a few months, you will only be eating about 20% of what you were previously consuming. Of course, that reduced intake means you must choose food more carefully to ensure you receive all necessary protein and nutrients.

The composition of meals will be much the same as if you were following a purely dietary strategy even without bariatric surgery. This will consist primarily of nutrient-rich fruits and vegetables plus high-protein foods, such as lean meat, eggs, and low-fat dairy or soy products. Any food with sugar listed as one of its main ingredients must absolutely be avoided.

Your body needs protein to recover after surgery and to maintain normal body functions. What it does not need are foods high in fat, sugar, salt, and calories. Alcohol consumption should also be limited since it is also high in calories.

How you eat is as important as what you eat. You should take small bites and chew thoroughly before swallowing. Insufficiently chewed food can become stuck in the stomach, which may cause vomiting, nausea, and abdominal pain. If you are eating in the correct way, it should take about 30 minutes to eat a complete meal.

With less stomach capacity, dehydration is also a concern. You will need to drink plenty of fluids, at least 2 liters per day of water, or similar low calorie drinks like tea or diluted juice. And, do not drink liquids within 30 minutes of a meal, nor carbonated beverages at any time.

Daily exercise is the last, and perhaps most important element of post surgery success. A minimum of 20 minutes per day is the goal. Assuming overall condition is healthy, most patients begin their exercise program about two weeks after surgery. Running, swimming, biking, really doesn’t matter so long as you’re burning fat and feeling good.
