The gastric bypass, also known as the Roux-en-Y gastric bypass, is a bariatric surgery that works by restricting the amount of food intake in addition to reducing absorptive capacity of food ingested.
The content has been reviewed for quality and accuracy to the best of our knowledge by Qunomedical and its Medical Board of Experts.
Gastric bypass surgery is usually recommended for any adult who has a BMI greater than 40, a BMI greater than 35 with comorbidities linked to obesity, such as type II diabetes, or a BMI greater than 30 with serious health problems.
This is the formula used to calculate the BMI: Weight in Kilograms / Height squared in Meters or weight (kg) ÷ height^2 (m^2)
Body Mass Index (BMI) is a globally accepted measure of body fat based on the relationship between height and weight.
Below the BMI weight categories:
During the surgery itself (also known as a "Roux-en-Y gastric bypass"), doctors restrict the stomach using surgical staples, leaving a walnut-sized pouch.
The surgeon will then reconnect the patient's small intestine (duodenum) to this small pouch, bypassing the rest of the stomach and artificially limiting the capacity of the body to ingest food and drink.
There are different ways to access the stomach area to carry out the surgery. In the past, surgeons would generally make a broad incision across the patient's belly to access the stomach.
Modern techniques are less invasive, using tiny cameras called laparoscopes to provide a view of the stomach. With the help of the laparoscope, surgeons can then insert the tools they need to use into tiny incisions, which heal faster, resulting in shorter inpatient stays and less pain.
When you choose to undergo a gastric bypass operation, expect a lengthy process of preparation before you reach the operating theatre. Diet is an important part of the process. Shortly before the operation, expect to be required to follow a diet that is designed to reduce fat deposits around the stomach and liver.
For a brief period following surgery, a purely liquid diet is essential. After that, patients need to gradually adapt their food intake to suit their restricted stomach capacity and recovery process. The stages in this diet will be clearly laid-out by your specialists and vary from patient to patient.
During the surgery itself, patients will be placed under general anaesthetic. Recovery times vary, but will be much shorter if a laparoscopic technique is used. In any case, the healing process usually lasts 3-5 weeks, and most patients leave the hospital within 3 days.
Gastric bypass procedures always lead to major lifestyle changes. This is most obvious in the food and drink you consume. You will need to radically reduce the amount that you eat and control the nutrients that you include in your meals.
Gastric bypass patients tend to require higher quantities of vitamins and minerals, generally derived from fresh fruits and vegetables. You are expected to reduce your intake of sugars considerably, while maintaining a high protein intake of 60-100g per day.
The vast majority of patients also need to take multivitamins on a daily basis following their gastric bypass, including the full range of micronutrients, from Vitamin D to Iron and Calcium.
Hydration also becomes vital. Gastric bypass procedures tend to reduce the body's capacity to absorb water, meaning that you should make sure to rehydrate regularly, even if you do not feel thirsty.
Physicians may make additional recommendations, such as avoiding non-steroidal anti-inflammatory drugs (NSAIDS), which can inflame the stomach. They will recommend a fitness regime in almost all cases. Although gastric bypasses radically restrict calorie intake, they must be combined with physical activity to maintain weight loss. Most patients change their lifestyles to include gym memberships or increased exercise as a result.
The cost of weight-loss surgery depends on the type of surgery being performed, the complexity of the procedure, the expertise of the surgeon, the general health of the patient, and the country in which the surgery is performed. The pricing differential depends on many factors, such as cost of living, exchange rates, practicing costs or regulatory conditions, which may differ greatly from country to country.

Like I said the experience was great the staff were all very helpful Alexandra was super I can't recommend her enough and Juste at the hospital.
From the start Alexandra was brilliant when I began looking into the surgery every question I had she answered and her manner was kind and helpful. She would call me regularly and send over any info I required promptly. Once I made the decision to go for the surgery things moved fast I booked the flights and paid the deposit. On arrival at the airport a driver met me and brought me directly to the hotel he pointed out the hospital on the way past. I arrived the day before my surgery. I was excited and nervous this was a new start for me. All the transfers to and from my hotel were arranged by my contact at the hospital Jannis/Juste. It was great to know you could call someone any time with questions or concerns and she was fantastic. I had the gastric bypass done after consulting with the surgeon. I fasted from the evening before and my surgery was the following afternoon. A taxi was arranged to pick me up early to go to the hospital for my pre op tests. It was like having an MOT they were very thorough and it made me feel safe. I went ahead and next thing I was waking up all over. The nurses were very attentive and I was in a private room with ensuite. The facilities were modern and very clean. I had one or two small problems after surgery with food and discomfort but I was well taken care of until it settled down. I spent 2 nights in the hospital originally and one more after because of discomfort I just had to stay on a liquid diet a little longer. The only issue I had before leaving was a darting pain in my left hip which I still have and was told would settle down. I was concerned about it being a clot and called juste in the middle of the night. She contacted the surgeon and they were sure it was not that but arranged a scan to confirm as I was flying home later that day. It was all clear and I was delighted with the response to my concern. I spent 3 nights in the hospital and 5 nights in the hotel. The only negative for me was the hotel even though I can't fault the staff it had no restaurant and limited seating area. This just meant that you were confined to your room alot. Also the location was close to the hospital but it had a nightclub next door which
meant loud noise on 3 nights. Otherwise my experience was very good and I would highly recommend this hospital. Like I said the experience was great the staff were all very helpful Alexandra was super I can't recommend her enough and Juste at the hospital. The only issue was the accommodation should be better I had to go to the supermarket to buy yoghurt soup and water as there was no restaurant at the hotel and they didn't have the natural yoghurt either. It was a big issue for me bcoz I was lucky I came around fast from the surgery and recovered well with only one or two issues but I was weak and having to go out in the cold to buy essentials 2 days after surgery was not good. When I told Juste she did send more supplies from the hospital but if the hotel had a restaurant these basic needs would have been covered.

Meine Erfahrung ist das alles gut organisiert war, aber ich keinen rate allein ohne Sprachkenntnisse der Landessprache oder Englisch allein auf den Weg zumachen.
Ich wurde vom Flughafen abgeholt und auch wieder hingebracht. Der Ablauf war gut durchdacht und lief ohne Probleme ab. Das Personal war sehr nett und hat mich gut behandelt. Das Krankenhaus war auch sehr sauber. Meine Erfahrung ist das alles gut organisiert war, aber ich keinen rate allein ohne Sprachkenntnisse der Landessprache oder Englisch allein auf den Weg zumachen.

Reyap Hospital in Turkey was the best
Reyap Hospital in Turkey was the best. I am healing brilliantly and am so happy with the results so far. My family were shocked when I told them ı would be getting surgery done overseas, expecially a big surgery like mine. Now that it is all over and I am very pleased with the results a few of my family members will be planning to get treatment done at Reyap Hospital aswell. I highly recommend this hospital. The environment is very clean. The workers are very caring and friendly and for sure they are very high in quality. Thank you Reyap Hospital :)

Mir hat es sehr gut gefallen der persönlichen Kontakt.
Ich habe eine anfrage in online gestellt über Magenbypass und bekam sehr schnell ein Antwort per E-Mail. Da ich im Urlaub war schrieb ich zurück und sagte das ich erst im August telefonisch zu erreichen bin. Der Anruf war sehr freundlich und informativ. Vereinbarten den Bauch OP für den 3.11.2018. Ich fuhr mit Auto dorthin und übernachtete im ein Hotel. An Freitag den 02.11.2018 ging ich ins Krankenhaus und würde alle nötigen Untersuchungen durchgeführt. Am meine Seite war die persönliche Beraterin , Sie war sehr freundlich. Die Krankenschwester und setzte waren immer zu stelle wenn Fragen oder etwas bräuchten. Der Krankenhaus ist sauber und der Personal sehr freundlich. Mir hat es sehr gut gefallen der persönlichen Kontakt.

From the first consolations till the last was perfect, professional and the best service.
I had a trouble at the airport as no one was waiting for us and we had to wait approx an hour for a taxi driver who wasn’t friendly or apologetic. After that from the first consolations till the last was perfect, professional and the best service. Excellent! Nothing bad I can think of!!!

I can assure you that you'll be in good hands at all levels!
So this is how it happened for me. I arrived in Kaunas on Sunday 4th of March where the taxi driver was already waiting for me with a tablet with my name on it. Juste was tracking my flight and called me right when we landed. I stayed in Kaunas from 4th to 14th of March. Monday 5th was all dedicated to pre-op exams. Process was quite smooth, Jogailé, my medical manager, who is in charge of foreign patients, was with me during all the time and took care of everything. She was with me during my scheduled visits to endocrinologist, blood test, endoscopy, ECG, etc. She welcomed me for my hospital admission, visited me everyday during my stay at the hospital, she went with me to the pharmacy, arranged taxi services and she took care of arranging the food delivery to the hotel after being discharged. Next day, March 6, was the surgery day, there again, all was taken care of. I arrived in a very nice individual room (picture attached) and the nurses were very helpful. Doctor came to visit me, we had a last talk prior to the operation. The Doctor is a very calm and qualified surgeon that put you in confidence and I went very relaxed to my surgery, which lasted 2 hours. As the operation went well, I stayed 2 nights at the hospital after surgery, and then in the hotel for another week . Before leaving the country, you have another visit with the doctor to check that you are apt for travelling. As for assistance, I went alone because my husband had to stay with our daughter. But it wasn't really a problem, Jogailé or Juste were always available by phone if you need something. If you can get someone with you for the company, it's fine, but in my case, Netflix did just fine! In terms of pain, I had painkillers all the time that I needed when I was at the hospital. I can't really say I had pain, it was more discomfort. I had 4 small stitches that healed when I left the country. I was able to sleep very well, but they offered me pills to help me in case I couldn't. Don't worry about pain, considering the type of surgery, it's not painful at all. Regarding the diet, the first days you can only sip some water, because you need to make your stomach work. And you have to do it little
by little, to see how your body reacts. This is very important, they will tell you all the time, because if you try to drink quickly as you used to, you may have nauseas or vomit. I only had 2 nauseas, and never vomit until April 6th when I re-introduce food, I must have eaten too fast. But overall, it is all good. The second day in the hospital, before leaving to the hotel, they gave me some tea, and I had to do the same, drink it little by little and not too hot. After that, my diet is based on liquids, yoghurts and baby food, something you don't need to chew, easy to swallow and in small quantities. That was the most difficult part for me. You won't be hungry, because one of the main advantages of these type of surgeries is that you're not hungry anymore... Now, 38 days after surgery, I have found the balance between what I eat and the energy I need during the day. Although I don't need as much as I used to, I don't feel weak. I'm feeling better every day and my stomach is getting used to the new diet. I think the weight loss depends more on the person and the amount of excess weight. In my case I had between 25/30 kg to loose, I've already lost 10 kg in 38 days. I had my 1 month post-op yesterday and the doctor said I'm doing well in term of results and it may take between 6 months to 1 year to achieve my objective. (See some pictures attached of my progress) As for the general Lithuanian mentality, they're obviously quite different from people in the US or from Portugal (where I live), but they're without any doubt very nice and helpful people. Wherever I went (shopping Mall, hospital, taxi...) they were always very nice to me, so don't worry about that, you'll not feel discrimination. One thing I noticed was ponctuality, the never miss an hour or are late! So overall my experience is very positive and I'll do it again with no hesitation. Fee free if you need anything else, but I can assure you that you'll be in good hands at all levels! Hope it helps and good luck if you decide to do it! Regards, Mouna

The hospital.....well I have never felt so comfortable, well looked after and confident about the staff and their abilities. [Qunomedical] would bend over backwards to facilitate you. They follow you from start to finish.
I was picked up at the airport. Transport was organised for appointments throughout my trip. The hotel staff spoke great English, were friendly and always done their best to facilitate my needs. The hospital.....well I have never felt so comfortable, well looked after and confident about the staff and their abilities. They explained everything in detail, provided a full work up beforehand and are experts in their field. The hospital was so clean you could eat your dinner off the floor. I would highly recommend. Diligent and competent at what they do. Would bend over backwards to facilitate you. They follow you from start to finish. There was some miscommunication at times. It's not something I think that needs to be fixed, I just think that's part of life 😁

Everybody was wonderful, very friendly and professional.
I want to thank everyone at Kardiolita for everything, everybody was wonderful, very friendly and professional. I will be telling people about your hospital. Thank you for the communication, if not this, I think I would have been too nervous to do all of this as I was so nervous. Big thanks to the doctor - she was wonderful. Thank you again!
