Key Information

The Roux-en-Y Gastric Bypass (RNY) is the most commonly performed bariatric procedure worldwide and is considered the 'gold standard' of weight loss surgery.
It works through a dual mechanism: restricting food intake with a small stomach pouch and decreasing the absorption of food by rerouting the small intestine to bypass the lower stomach and duodenum.
The surgery involves dividing the stomach into a small upper pouch and a larger lower remnant, then attaching the small intestine to both. The entire procedure takes about 4 hours and is performed laparoscopically.
RNY produces significant long-term weight loss (60-80% of excess weight) and is associated with the improvement or resolution of over 90% of certain health conditions, including diabetes and high blood pressure.

About Laparoscopic Gastric Bypass (RNY) Surgery

The Laparoscopic Gastric Bypass procedure, otherwise known as the The Roux-en-Y Gastric Bypass (RNY) is considered the ‘gold standard’ of weight loss surgery and is the most commonly performed bariatric procedure worldwide. It works by restricting food intake and by decreasing the absorption of food. 

Food intake is limited by a small pouch that is similar in size to the adjustable gastric band. In addition, absorption of food in the digestive tract is reduced by excluding most of the stomach, duodenum, and upper intestine from contact with food by routing food directly from the pouch into the small intestine.

The weight loss results of gastric bypass surgery are generally good. Most patients lose an average of 10 pounds per month and reach a stable weight between 18 and 24 months after surgery. Often, the greatest rate of weight loss occurs in the very beginning (that is, just following the surgery when you are still on a liquid diet).

The Gastric Bypass surgery entails dividing the stomach into a small upper pouch and a much larger lower “remnant” pouch and then the small intestine is rearranged to connect to both. 

The operation is performed by our surgeons laparoscopically and involves making five to six small incisions in the abdomen through which a small scope connected to a video camera and surgical tools are inserted. 

The surgeon staples the top portion of the stomach so it is separated from the bottom to create a small stomach pouch. 

This small pouch restricts food intake. 

A section of the small intestine called the jejunum is then attached to the small stomach pouch permitting food to bypass the lower stomach, the duodenum. This bypass reduces the amount of calories and nutrients the body absorbs, called malabsorption.

The surgeon then takes the end of the small intestine that is still connected with the remainder of the stomach and attaches it to the bottom of the “Roux limb.” This allows the digestive juices produced by the stomach to meet up with the food in the intestines

In addition, there are 2 catheters (tubes) used to keep both portions of the stomach clear – the first is inserted through the mouth and into the pouch. The second is for the larger portion of the stomach and is threaded through an opening in the side of the patient’s abdomen.

Rarely, a cholecystectomy (gall bladder removal) is performed to avoid the gallstones that may result from rapid weight loss. More commonly, patients take medication after the operation to dissolve gallstones.

The procedure itself takes about 4 hours to complete.

Most people typically stay in the hospital for 2-3 days after gastric bypass surgery.

  • Average weight loss after the Roux-en-Y procedure is generally higher if you rigorously follow instructions than with other restrictive procedures.
  • A year after surgery, weight loss averages at 77 percent of excess body weight.
  • Over 90 percent of certain health conditions – including back pain, sleep apnea, high blood pressure, diabetes and depression – were improved or resolved over time.
  • Produces significant long-term weight loss (60 to 80 percent excess weight loss)
  • Restricts the amount of food that can be consumed
  • Produces favorable changes in gut hormones that reduce appetite and enhance satiety

Before traveling to Cyprus, as part of your Gastric Bypass surgery preparation you will complete a detailed bariatric specific questionnaire, which will allow our doctors to determine your eligibility for Gastric Bypass surgery. If you are not ready to make lifestyle changes, you will not be considered eligible for the procedure. 

To help you adjust to your new lifestyle, we advise you to empty your home of all edible “temptations”, creating a suitable environment for your return, post operatively.

Ten days prior to your arrival in Cyprus, you will receive all the necessary pre operative instructions, to prepare yourself both physically and mentally for your chosen procedure.

After hospital admission, you will receive psychological advice. This will help you adhere to a healthier lifestyle. Without changing your lifestyle, the surgery will not be a success. You will also receive nutritional counseling before (and after) your surgery, by our specialists.

Upon your discharge from the hospital you should be able to:

– Move without too much discomfort

– Eat liquid and/or pureed food without vomiting

– No longer require pain medication given by injection

You will remain on liquid or pureed food for several weeks after the surgery. Even after that time, you will feel full very quickly, sometimes only being able to take a few bites of solid food. This is because the new stomach pouch initially only holds a tablespoonful of food. The pouch eventually expands. However, it will hold no more than about one cup of thoroughly chewed food.

You will be instructed on eating small meals frequently throughout the day, rather than large meals that your stomach cannot accommodate.

Your new stomach may not be able to handle both solid food and fluids at the same time. So, you should separate fluid and food intake by at least 30 minutes and only sip what you are drinking. You won’t be able to tolerate large amounts of fat, alcohol, or sugar. You should reduce your fat intake, especially fast food meals, deep-fried foods, and high-fat foods, as well as high-sugar foods like cakes, cookies, and candy.

You can generally resume exercise 6 weeks after the operation. Even sooner than that, you will be able to take short walks at a comfortable pace, with the approval and guidance of our doctor. Exercise improves your metabolism, while both exercise and attending a group support can boost your self-esteem and help you stay motivated.

Following your recovery diet you will slowly begin to introduce new foods in increasing quantities until about 6 months after surgery when your new bariatric diet will be in full swing. All weight loss surgery procedures require a complete change in diet for your procedure to continue to be effective and Laparoscopic Sleeve Gastrectomy is no different.

Assuming you follow the diet and exercise guidelines of our surgical team, all indications are that weight loss and health improvement following Sleeve Gastrectomy surgery may be permanent. However, some patients are likely to experience weight regain as a result of your stomach stretching over time.

After surgery, you will need a new nutrition plan. Our surgeon and/or dietitian can help you learn about and get used to the changes in lifestyle and eating habits you need to make. It is very important to follow the eating and drinking instructions beginning immediately after the operation. 

In the first few weeks after your surgery, you will be on a liquid diet since only thin liquids will be tolerated by your stomach at that time. As you heal, you will gradually progress to pureed foods (three to four weeks post-op) and then soft foods (five weeks post-op). Finally, you will be able to eat solid foods.

When you are at the stage to eat solid foods without problems, you will need to pay close attention to your diet. 

Upon follow up, your doctor will determine if you need replacement of iron, calcium, vitamin B12, or other nutrients. Supplements, such as a multivitamin with minerals, will be prescribed to provide any nutrients that you may not be getting from your diet. 

It is recommended that you eat only three small meals a day and make sure that these meals contain adequate nutrients. Foods that have a concentrated supply of calories with little nutritional value, such as milkshakes, syrups, jam, and pastries, should be avoided as much as possible.

Exercise is very important and incorporating regular physical activity into your daily routine is as important as following your nutrition plan. 

Often Weight Loss Surgery patients have been inactive due to decreased activity tolerance, psychological constraints and in some cases, physical disabilities. After Laparoscopic Sleeve Gastrectomy aerobic activities, particularly walking and gentle swimming are generally best tolerated. Your surgeon will advise you on which activity is right for you.

Testimonials

I happily recommend the services of the GMS team. I needed a unique procedure which is not performed in Israel and I turned to them. 

Over a telephone conversation with GMS representative Roy, I felt caring attention and confidence that he would help in everything. He accompanied us throughout the entire process, before the flight and even after. 

In addition to Roy, we would like to sincerely thank Oriya, our allocated Israeli speaking patient coordinator of the company in Cyprus. 

Even before our departure, Oriya was in touch with us helping with any issues and made sure that we arrived fully prepared – taking into account the smallest details; even to the point of finding out our food preferences, and despite the late hour of our arrival at the hotel, she ensured an exquisite meal was waiting for us in the room. Oriya greeted us upon arrival and truly made us feel like we were her personal guests. She accompanied us throughout the entire day of the operation – attentively, with endless care and continued patience.

I felt like I had a good friend with me in the hospital. This kind of treatment doesn’t happen very often… At the end of the day we parted, hugging each other, and Oriya gave recommendations on where to go and what to do in the time remaining before returning home.

I just don’t have enough words to thank GMS and Oriya for everything. I can only recommend with a reassurance that those who need it should use their services.

When I was looking for information about palm surgery, I found many recommendations about Dr. Amir Oron. After a consultation with Dr. Amir, I was surprised to learn that my health insurance does not guarantee that he will be the surgeon to perform the procedure.

That is when I contacted GMS, who explained how I could have the surgery performed by the physician of my choice – which gave me peace of mind. It is very important for me to share my experience, as the service I received through GMS exceeded any similar experience in Israel: From the beginning I was assigned a GMS representative from Israel, who explained in detail what my experience would be and answered all my questions about the operation and the treatment process. (Thanks, Roy!)

All I had to do was fill out the application form. GMS representatives took care of everything themselves!

They contacted the insurance company on my behalf and even had them check the status of the application until the financial commitment for the surgery was received. We agreed with on the surgical date, booked the flights at a convenient time for me, and also dealt with the hotel reservation. The GMS staff even reviewed the menu and took any dietary restrictions into consideration on my behalf.

We were picked up from the airport in Larnaca, Cyprus where we met the wonderful Oria, who accompanied us throughout the entire visit and took care of every detail; from registration to preparation for the operation.

This is essentially a VIP service that made the entire experience relaxed and stress-free.
The assigned coordinators continued caring after my return to Israel. They were interested in my recuperation post-operatively and also ensured all financial matters were dealt with; all this, by the way, without any commissions or payouts on my part, but directly with my insurance.
In a word – an amazing experience!
In short – I recommend it!

Thank to GMS, thank you Roy, thank you Uriah and thank you Dr. Oron.

Roy – thank you for your patience, quick responses (minutes!), availability, caring and clear explanations! You are inimitable! Oriya – you are amazing! Thank you for every smile, hug, help, guidance, explanation… really! You are simply amazing!

Every time I was asked by friends and family about the surgery, I immediately started talking about your amazing service! I felt warmth and love, and everyone who was with me felt the same!
We never stop talking about you, and really, only good things!

You have entered our hearts!
Thank you very much for everything! I hope to see you in the future, under different circumstances.

When one thinks of “Medical Operation” overseas, the last thing that comes to mind is a “Great Experience”, but this is exactly what I have experienced, going through a prostate removal procedure via GMS Cyprus. With their professional and compassionate approach, the GMS Cyprus team provides to the confused and worried patient a complete transparent VIP envelop, which takes care of all the logistics involved in “Medical Tourism” for the patient and their escort, as well as assembling a world class international medical team and medical facilities suitable to treat the medical diagnosis at hand.

From the first time the medical situation was diagnosed, and the first contact was made, the GMS team was there to remove the hassle and understand my concerns and worries about the medical issue and being far from home, and they handled every detail of the logistics of travel, insurance company requirements and medical preparations. From first arrival at the luxurious hotel, assigned to the first night and for my personal escort, the GMS management, Udi and Clair, has treated me as family away from home and personally came to greet me and attend firsthand to all my needs and requests. To top it all, they assigned their own personal escort, the wonderful Aia, which was available 24/7 and door to door to handle any need and detail and helped interface with the local hospital team.

I want also to recommend the choice of the hospital at Limassol, which is modern and clean, and of course GMS team have in advance reserved a private and spacious room and nominated a local doctor, which was familiar with my case and participated in the treatment and which came often to check my condition and parameters.

To summarize, I would not go so far as to wish such treatment to anybody, but if you must go through the medical procedure, the VIP treatment provided by GMS is a legitimate alternative, combining easy logistics, professional medical treatment by your own doctor, modern hospital, relaxed overseas experience and personal compassionate escorting to ease and sweeten the experience.
