The Gastric Sleeve surgery is commonly referred to as “vertical sleeve gastrectomy” and is a surgical treatment method for weight loss. During the Gastric Sleeve surgery, approximately 80% of the stomach is removed, leaving behind a stomach that is roughly the size and shape of a banana. This helps individuals consume less food and consequently lose weight. However, it’s important to note that this surgery is not limited to weight loss alone. It can also assist in managing a range of serious health issues related to obesity, such as hypertension, diabetes, and sleep apnea. Turkey has become an international health tourism destination for Gastric Sleeve surgery. Every year, thousands of patients visit Turkey to undergo this procedure. The country’s modern healthcare facilities, experienced surgeons, and patient-centered services make Turkey a preferred location for this surgery.

Additionally, the cost of Gastric Sleeve surgery in Turkey may be quite affordable compared to other countries. This makes it an attractive option for international patients. The combination of low cost, high quality, and professional healthcare services contributes to Turkey’s prominence in the health tourism sector.

Benefits of Gastric Sleeve Surgery

  • It is applied laparoscopically, thus, this way accelerates the wound healing of the patient.
    Stomach capacity is reduced by this surgery, causing many foods to be consumed in lesser amounts.
  • Since the part of the stomach that produces the hunger hormone is removed, a decrease in appetite and rapid weight loss are observed.
  • Dumping syndrome is prevented.
  • Since the food taken leaves the stomach late, the feeling of fullness in the stomach lasts for a long time.
  • Ulcer formation is minimized during surgery.

    During my surgery, my doctor Abdullah and his medical team supported me every step of the way and were there for me whenever there were any questions or concerns. I was surprised by my post-operative weight loss and immediately noticed the positive effects on my physical health. Thank you very much everyone!!!!!!!

  2. Gunita

    Not only did I lose weight, but my self-confidence also increased. I feel more energetic and there has been a marked improvement in my overall quality of life. Sleeve surgery was not only a method of weight loss, but also the beginning of the transition to a healthier lifestyle. If you are struggling with weight issues and want a real change, I highly recommend you consider Letsmedi.

    The best Doctors and nursing team. My journey begins today my people. I’m being looked after well @ Dr HE Hospital. My new life has started. Thanks for the support everyone on here. Thanks my coordinator Luna and Lestmedi. I can’t thank them enough.

  12. Marshalla Cullum

    Letsmedi and their team amazingly professional and friendly experience from beginning to end! I cannot recommend Letsmedi enough. You are looked after from the minute you leave the airport to the minute you return and have full support even when you’re home thanks to their aftercare Whatsapp group. My sleeve surgery went extremely well and all the staff take care of me after me even with my unpredictable diabetes. I am two weeks post op and have lost 7.5kgs.

    Hello! I had an operation on March 3 2022. 15 days after the operation I ate liquids, it was not difficult for me to do everything perfectly, nothing hurts my skills minus 10 kg, I am so glad to have operation, I even forgot that I had an operation. Many thanks to the Letsmedi clinic and to my doctor Abdullah Shishik and his team! I am glad that I chose you ❤️

  14. Gemma

    I can’t speak highly enough about my journey. My coordinator Luna was the best I have ever dealt with and during my research I spoke with too many co-ordinators at hospitals all over Turkey ,she is an absolute credit to Letsmedi. I was so fearful given I have never been in hospital before but Luna put my mind at ease. In arrival me and my companion were collected from airport when we arrived at the hospital we were greeted by someone who took us to our room which was spotlessly clean and look like a hotel room. I met with a translator who was very welcoming. My surgeon Dr Sisik came across as a very genuine, warm and kind Dr. Really wonderful man. I would not hesitate to recommend Letsmedi to any of my friends who were considering surgery in Turkey. Today, I am two weeks post op, no complications, healing nicely and am 15lbs down. A huge thank you to everyone involved in my journey for everything you have all done for me. I will never forget the care I had from start to finish.

Operation was good and really seeing the weight coming off.The team are very helpful also ready to help you out or answer questions.

Is Fertility and Pregnancy Affected by Gastric Sleeve Surgery? Michael asked on 13/05/2022

Infertility will improve after surgery. The probability of getting pregnant will increase in patiants who cannot become pregnant due to high weight. In case of pregnancy (our recommendation is 1 year after the surgery ) no additional problems will arise.

What pain medication can I take after gastric sleeve surgery? Alice asked on 11/03/2022

As long as you are in hospital , you'll have an adequate pain relief plan. After discharge there will be no need for painkillers. Paracetamol and the like can be used if needed.
