Gastric Sleeve at Luna Clinic Turkey

How Does it Work?

Gastric sleeve is a weight loss surgery, that works by restricting the amount of food intake by reducing the stomach’s size by 15% to 20%. As we said before, the surgery is for;

  • Individuals with BMI more than 35
  • Individuals without diabetes
  • Individuals not addicted to sugary foods, alcohol or acidic beverages


What is BMI and How to Calculate It?

BMI is an acronym for Body Mass Index –which is value derived from calculating one’s body fat, based on the relationship between their height and weight.

The formula to calculate the BMI is: weight in kilograms / height squared in centimeters


What does a Gastric Sleeve Surgery involve?

Gastric sleeve is a laparoscopic procedure. This simply means that it is an operation performed in the abdomen or pelvis using small incisions with the aid of a camera.

When you decide to undergo the gastric sleeve surgery, we will plan and customize the surgery according to the best clinic practices and your preferences and needs. Your first consultation will be done online, and when you arrive at the clinic, you will have your final consultation which will be done face-to-face between you and your surgeon.

Here are some of the steps you can expect during the surgery: 

1.     Taking the anesthesia

To make you feel comfortable during the surgery, your surgeon will give you general anesthesia right before the surgery commences.

2.     Procedure

When the general anesthesia is applied, your surgeon will create a small stomach "sleeve” using a stapling device and the rest of the stomach is permanently removed. In laparoscopic sleeve gastrectomy, a tiny camera placed in the stomach allows the surgeon to see inside the patient's stomach.

During the surgery, your surgeon will make two to five small incisions in the abdomen and the laparoscope and other instruments needed are entered through these openings. Then a large portion of the stomach is removed and the remaining portions of the stomach are joined together using surgical staples. Thus, a long vertical tube or banana-shaped stomach is created.

3.     Post-Op Instructions

For the first few days after surgery you need to rest. You should ensure that you have someone who can help you at home not to force yourself to do necessary things. You should not lift anything over 10 lbs for 10 days after surgery and any strenuous exercise for 6 weeks after the surgery is not allowed as well. Small walks are recommended immediately after the surgery. This will help your lungs, circulation and speed recovery and also important to get rid of gas. You can usually return to work and your normal life four to six weeks after the surgery once the stomach heals.


Things You Should Do Before Surgery

  • A week before the procedure, you should stop taking Aspirins and any other meds associated with blood thinning.
  • If you are allergic to any drugs, you should inform your surgeon as soon as possible.
  • Patients advised to avoid smoking 24 hours before the surgery.
  • Consuming any alcoholic beverages can affect anesthesia. So you should not take in anything alcoholic 24 hours prior surgery.
  • If you are taking meds for chronic or acute diseases such as diabetes and heart disease, you should inform your surgeon before the surgery commences. 
  • You also will be placed on a high protein, very low-calorie pre-op diet 2-3 weeks prior to surgery. All fats, butter, fatty meats, fried foods, whole milk products and high sugar foods should be eliminated from your diet. 


What Should I Eat After a Gastric Sleeve Surgery?

One week after surgery

For about a week after surgery you should consume only clear liquids. you are also not allowed to take soft or solid food after one week from a gastric sleeve surgery. Solid foods may cause stapler line opening and leakage after surgery. During this period, liquid foods, low-calorie and low-fat soups, jellies, protein drinks can be consumed. An important note at this stage is that the liquid foods consumed must be low calorie and fat free.

2-5 weeks after surgery

At this stage you can eat mashed foods. Excess food intake can cause discomfort and vomiting. Mashed meat, potatoes and all kinds of fruit puree can be consumed. Again, low calorie and fat-free should be considered. Foods such as processed sugar and concentrated fruit juice should be avoided, as well as the consumption of carbonate-containing liquids is prohibited for one month after surgery.

6-12 weeks after surgery

During this period, soft foods can be slowly added into your diet. Cheese, well-cooked vegetables (through the blender) and protein foods can be eaten. The time between meals should be longer than 4 hours and each meal should be slowly chewed and eaten, for example, in a minimum of 30 minutes.

4 months after surgery

After 4 months, you can gradually and regularly switch to a normal diet. Meats, eggs, vegetables and legumes can be consumed. However, carbohydrate foods such as rice, pasta, bread may not be tolerated by the body for a few more months. 

First 2 years after surgery

Caloric intake can be increased to 1000-1200 levels if strictly followed the instructions so far and after the expected amount of weight loss has been achieved. Although a common dietary example for post-surgery is given herein, it is possible to add or remove certain foods from the diet according to the tolerance level of the individual. In addition to establishing a diet, you should be ready for a certain amount of regular exercise before and after surgery. This increases the expected weight loss and prevents weight gain again.



Is Gastric Sleeve Painful?

You may feel pain or soreness after the procedure is done. However, your surgeon may prescribe painkillers to relieve this pain and discomfort.

Does Gastric Sleeve Leave a Scar?

If gastric sleeve procedure is performed through single-incision laparoscopic surgery patients usually will have one small scar hidden in the belly button. If it is performed as multi-port laparoscopic surgery, patients will have 4 to 5 small scars across the abdomen. If open surgery should be considered, there will be a larger scar across the abdomen.

How Much Weight Will I Lose With The Gastric Sleeve Procedure?

You will lose 60-70% of their body weight on average within two years after surgery, especially in the first year.

    My weight has been an issue for me all my life and no matter what I do, I just can’t seem to get it under control. It was starting to really affect my health and quality of life so I decided to look into getting weight loss surgery. I found this clinic that offered me a great package and made me feel super comfortable throughout the process. It was really difficult for me to make the choice to get surgery but I am so happy that I did. Also thank you Flymedi for arranging everything and being there for my every question during this process!

    Angela went above and beyond my expectations. She is very friendly and you can always feel at ease contacting her. She made sure I was comfortable with our choice of surgeon Dr. Can Karaca and set up a video call for me. Always ready to help and answer any questions (she would always be available despite the 7 hour time difference)! I wasn’t really sure about traveling to Istanbul, Turkey for my procedure until I met Angela and she explained everything from start to finish and stood behind her words to always be of assistance. Mind you I have been researching for months now for a good doctor and went back and forth between waiting 2 years to get my surgery done in Canada or even traveling to Mexico for it! I was thinking Turkey would be a difficult route due to time difference and the distance but I’m very happy I chose to go to Turkey with Flymedi and I’m glad my agent was Angela Sabou! Do not hesitate to work with Flymedi and especially request Angela if you can!!! - a very satisfied client

    I attended Kardiolita hospital in February for a gastric sleeve bariatric surgery. From the moment I entered the hospital, I knew this was the best choice I could have made. It was extremely clean, I had a dedicated lovely lady who brought me around the different areas for serrated tests the day before hand. She gave me her number to text if I had any questions afterwards. The next day I came back for my surgery. I had a huge private room to myself. I met with my surgeon, who was lovely. He explained my options between two different types of bariatric surgeries. He explained pros and cons of both and let me decide. Surgery went without any complications. The nurses were fantastic. They would change my dressings and give me pain medication when needed. They made me feel looked after and cared for. The surgeon came back a few time’s to check on progress and then I was allowed leave after 2 nights in the hospital. I felt great after the surgery. I was able to change my dressings and adjust to the eating regime I was given by the dietician. Afterwards, I required a lot of paper work for insurance purposes etc. I have to commend the staff who have been helping me gather the huge amount of paperwork requested. They helped me every time with the back and forth requirements for further paper work. I would HIGHLY recommend Kardiolita hospital. It’s better than any hospital I have been to in Ireland.

    Nadia is a very amazing and helpful woman. She helped me find a hospital that suits my situation perfectly. She also helped me find a “guide” who helped me throughout my tests and my surgery (gastric sleeve) . I went to Erdem hospital which has one of the most dedicated crew of nurses and doctors who cared for my every need regardless the hour of day. I recommend them very much!!!!
