Gastric bypass surgery, also called Roux-en-Y gastric bypass, is a type of weight loss surgery that involves forming a small pouch from the stomach and connecting the newly formed pouch directly to the small intestines. Roux-en-Y Gastric Bypass surgery is the most common bariatric surgery in the world. In this procedure, both the stomach volume is reduced and the absorption is limited. It reduces the amount of foods that are eaten, but also ensures that some of the nutrients consumed are removed without being absorbed. The Roux-en-Y Gastric Bypass allows patients especially those who desire to get rid of the weight-related health problems to lose their stubborn excess weight in a very short time.

Gastric bypass surgery is recommended for patients suffering from obesity or morbid obesity. As a rule of thumb, patients with a BMI (body mass index) over 40 are considered morbidly obese. Individuals who still struggle to lose weight although they tried all other weight loss methods, such as diet and exercise are also good candidates for the gastric bypass surgery.

Patients suffering from the following can also benefit from gastric bypass surgery: 

● Type 2 diabetes 

● Insulin resistance
● Sleep apnea 
● Hypertension 

● Non-alcoholic fatty liver disease (NAFLD)
● Asthma 
● Other comorbid conditions associated with a high body mass index

I travelled all the way from US by myself to come here and get rhinoplasty done, my surgery was a week ago by Dr Hasan duygulu he is extremely professional and excellent at his job. My whole stay was made very easy and comforting by Kate, Sultan and Enes. I have been coordinating with Kate this whole time from the start till the end. She has been amazing throughout and ensuring. They all were there for me when i needed them and even after. It was a great decision for me and i m totally proud of myself that i was able to find the best and proceeded with it. I thank everyone part of luna clinic and the hospital for your kind and loving hospitality. I will recommend coming to Dr Hasan to everyone and anyone without any hesitation

I would highly recommend Flymedi and Abud

I would highly recommend Flymedi. My mom had a gastric balloon fitted at the Luna clinic and everything went smoothly. When I was looking for a clinic in Turkey I found Flymedi as medical tourism, I contacted them by email and they got back to me in a short time. I was assigned Abud as health coordinator and I don’t have enough words to thank him. He’s professional but on top of that he loves what he’s doing and he does really care. As I said before I don’t have enough words to thank Abud and Flymedi and I’m so happy I made the right decision by choosing them. If you want to have the bed experience choose Flymedi and you won’t regret it.

Rhinoplasty 12 days ago- Luna Clinic- Dr. Hasan Duygulu

I had my rhinoplasty done exactly 12 days ago with doctor Hasan Duygulu. Before flying to Istanbul, I was very scared of doing this somewhere far from home but , from the first day of our arrival I knew I chose the right clinic; we met Sultan at the gate of the hospital, she was extremely nice and accommodating and organised, she comforted and still comforting me with answering every question and concerns possible and was with me through the whole before, during and after process which I am still experiencing btw. At the day of the surgery we met doctor Hasan, he is very nice and professional, I told him what I wanted and he took pictures of my face and showed me what my nose could approximately look like after the surgery and addressed my concerns and questions which were a lot btw :) he came to visit me right after I woke up and the next morning as well. The hospital was very luxurious and the nurses were very nice and all our needs were met perfectly, everything was super organised and easy. Today I removed my cast and I am very happy with the results as early as it is with the swelling I am very satisfied and I cant wait to see the final results which seem to be very close to the pictures he showed me. Thank you Luna clinic and especially Sultan for making this life changing decisions the best decision I made. The whole experience was easy, trusted and comfortable thanks to you

I would definitely recommend booking through Flymedi.

If you are thinking about surgery in Turkey, I would definitely recommend booking through Flymedi. Abud was my contact and is there for you 24/7. He was quick to respond and did his very best to answer every question and keep me calm in what can be, a new and scary experience. I would highly recommend and you can be sure you are lucky if he is your contact. The hospital was very clean and staff were very professional and kind. The doctor did an amazing job and I am thrilled!!

Totally recommend

The whole process went really smooth from the beginning, it was really easy to communicate with them. I had my mommy makeover done in June, 2021 and the only thing I regretted is putting off my surgery for some years because I did not want to travel abroad, but in the end it was all worth it. The prices are much lower and I was happy with my surgeon (Prof. Omer), he is such a friendly person and an amazing surgeon as well. I love my results and I've never felt so confident in my body, even before the pregnancy. I can recommend Flymedi and my surgeon in particular.

Number Of Trips Abroad

1 trip

Discharge From Hospital

Patient is required to stay 4 nights in the hospital

Duration Of Operation

2 to 4 hours

Preparation

The patient should stop smoking at least 3 weeks before undergoing surgery, as smoking can increase the risk of complications and endanger the healing process. The patient also should stop the intake of vitamin E, blood thinners such as aspirin and ibuprofen at least 2 weeks before surgery.

How It Is Performed

The patient is first administered general anesthesia before the procedure can begin, making it painless. 

The gastric bypass surgery can be divided into two main parts: 

In the first part, the surgeon will create the smaller upper stomach and the larger lower stomach by using staples, effectively dividing it into two. The top section of the stomach (called the pouch) is where the food patients eat will go and helping them feel “full” with very little effective food intake. This will help the patient eat less and lose weight. The upper stomach can hold about 1 ounce (oz) or 28 grams (g) of food before it goes into the small intestine.

The second step is the bypass. The surgeon will connect the small intestine to the smaller upper stomach. The ultimate goal of the surgery is to help the patient’s body will absorb fewer calories.

There are two main techniques which can be applied during the gastric bypass surgery: 

 

There are a few advantages of laparoscopic gastric bypass surgery technique, as it is a minimally invasive procedure: 

● Faster recovery and a shorter hospital stay 
● Less discomfort and pain during recovery
● Much smaller scarafter the surgery 

In both cases, the surgery lasts anywhere between 2 and 4 hours, and the gastric bypass surgery recovery timemay begin.

Recovery

Most of the patients stay in the hospital for 3 to 5 days and may return to normal activities in 3 to 5 weeks.

Risks

Gastric bypass complications can include the following: 

● An allergic reaction to certain drugs 

● Anesthesia risks
● Blood loss 
● Blood clots 
● Stroke or heart attack during surgery 
● Different types of infection 

● Infections in the stomach 

● A blockage of the intestine or stomach

Side Effects

Gastric bypass side effects can include: 

● Moderate swelling and bruising

● Constipation 
● Developing gallstones 

● Mild to moderate discomfort or pain
● Infection of the incision site 
● Dumping syndrome

Success Rates

Based on 513 gastric bypass surgery reviews sets the satisfaction rate at 96%. 

Before And After

Patients can expect to lose anywhere between 4 to 9 kilograms every month after the procedure. On average, gastric bypass weight loss is around 60% of the patient’s extra weight – this results in a healthier lifestyle with reduced risk from comorbidities. If the patients follow the aftercare and dieting instructions carefully, they can reach their best outcome and maintain it more easily. 

Faq

Is There A Gastric Bypass Alternative?
Yes, there are many types of bariatric surgery, including lap band surgery and gastric sleeve surgery as alternative treatments to gastric bypass procedure. 

Gastric Bypass Vs. Gastric Sleeve – What Is the Difference?
In gastric sleeve surgery, a large part of the stomach is surgically removed and the surgeon gives the new stomach the appearance of a "sleeve." 

Gastric Bypass Vs. Lap Band – What Is the Difference?
Gastric lap band surgery uses a band to divide the stomach into two portions. In this procedure, the stomach is not stapled or changed in any way - the lap band creates a blockage in the upper stomach, helping the patient eat less.
