For a Healthy Life

a moment in surgery
Assoc. Prof. Dr. Umut R. Gündüz was born in Ankara in 1978. His educational journey, which started in Ankara, continued in Istanbul, where he received the title of Medical Doctor from the Cerrahpaşa Faculty of Medicine. Between 2005 and 2010, he completed his General Surgery residency at Okmeydani Training and Research Hospital and became a general surgery specialist. He maintained the work tempo to which he was accustomed during his residency at Antalya Training and Research Hospital, where he was appointed at the beginning of 2011. He operated on many patients in the fields of emergency surgery, laparoscopic surgery, hernia surgery, malignancy surgery, and obesity surgery. He applied for associate professorship with the scientific articles he published during his specialization; at the end of 2017, he successfully passed the associate professorship exam and received the title of associate professor. During this period, he also received advanced endoscopy training at Istanbul Training and Research Hospital. He worked as a clinical instructor at Antalya Training and Research Hospital until 2021 and actively participated in resident training programs. He performed many complex surgeries and has a special interest in laparoscopic surgery, oncological surgery, and obesity surgery. In mid-2021, he began working at Private Termessos Hospital and successfully performed numerous laparoscopic obesity surgeries. A year later, he established his own clinic. He currently serves his patients there while continuing to perform surgeries at contracted hospitals.
Cancer Surgery

A multidisciplinary approach and a planned first step are the basis of the fight against cancer.

Laparoscopic Surgery (key hole surgery)

Surgeries performed through small incisions in the abdominal area with special hand tools…

Endoscopic procedures

It is possible to lose weight with endoscopic methods for patients who do not need obesity surgery…

Doktor gibi Doktor kelimesini Umut Rıza Gündüz için kullanmak gerekiyor. Çünkü sadece Tıp Fakültesinde öğrendikleriyle doktorluk yapmıyor. Yüreğini, Tecrübesini, Bilgisini daima yenileyerek kendini geliştiren Muhteşem ötesi Doktor teşekkürler Seni tanımakta, Senin hastan olmak bir ayrıcalık iyi ki varsın

Süper bir insan, süper bir doktor.2012 yılından beri ailemizin doktoru.Önce babama bağırsak ameliyatı yaptı.Ayni yıl anneme mide ameliyatı yaptı.Annem şuanda 87 yaşında ve Umut Rıza doktora deyip hep dua ediyor.2018 yılında ben meme kanseri oldum ve Umut doktor beni de ameliyat etti sağlığıma kavuştum.Gecen sene karaciğer bizi korkuttu ama Umut Rıza doktorumuz hemen yetişti Allah razı olsun ondan.Gözünüz kapali olarak gidip ameliyatının korkmadan yaptırın lütfen bu sayfayı okuyan hasta kardeşlerim.Ben emekli bir öğretmenim ve 66 yaşımdayım.Allah’ım böyle iyi bir doktor ülkemizden başka ülkeye gitmesin.Umut Rıza doktorumuz çok yaşasın.

Kesinlikle tanınması, bilinmesi gereken bir doktor! Kendisinden bilgi ve tecrübe akıyor. Tabii tüm bunların üstüne bir de güler yüzü ve hastasını rahatlatan samimi mizacı eklenince takdire şayan bir beyefendiyle karşılaşıyorsunuz.

Dr. Umut Rıza, hayatımı değiştirdi! 2020 yılında tanıştık. Sonrasında onkoloji hastası oldum ve meme kanserine yakalandım. Doktor beni kuyumcu gibi ameliyat etti! Göğsüm korunmuştu ve dikişler görünmüyordu. Önemli olan iyileşmeye başlamamdı. Ardından hormon tedavisi gördüm, sürekli aç kaldım ve çok kilo aldım. Güvendiğim birine başvurdum ve sorunumu anlattım! Umut Rıza bana bariyatrik mide küçültme ameliyatı önerdi! Hemen kabul ettim çünkü ona %100 güveniyorum! Umut Rıza, üst düzey bir doktordur! Böyle doktorlar bir elde var! İnan bana, ben de doktorum! Ve doktorla birlikte çalışan ne harika bir ekip! Herkes özenli ve kibardı, sürekli benimle ilgilenildi! Hemşireler çok olumlu ve profesyoneldi! Bu bir sihir! Ameliyatım mükemmel geçti! 40 kilo verdim! Yaşımdan daha genç görünmeye başladım! Kendimi 30 yaşında gibi hissediyorum, halbuki 53 yaşındayım! Fazla kilo problemi yaşayan herkese yardım almayı tavsiye ediyorum; mükemmel bir uzman olan Umut Rıza ve profesyonel ekibi size yardımcı olacaktır! Tek bir tavsiyem var: Çok fazla büyük beden kıyafet almayın!!! Onları atmak zorunda kalacaksınız! Sihirbazıma sağlık ve uzun ömür diliyorum! Doktor Umut Rıza, bana yeni bir hayat verdin! Teşekkür ederim ve Tanrı sizden razı olsun! 🙏🙏🙏♥️♥️♥️

Like Doctor, the word Doctor should be used for Umut Rıza Gündüz. Because he does not practice medicine only with what he learned at the Faculty of Medicine. Thank you to the amazing Doctor who always improves himself by renewing his heart, experience and knowledge. It is a privilege to know you, it is a privilege to be your patient, I am glad to have you.

He is a super person, a super doctor. He is our family’s doctor since 2012. He first performed an intestinal surgery on my father. In the same year, he performed a stomach surgery on my mother. My mother is now 87 years old and always prays for Umut Rıza doctor. In 2018, I had breast cancer and Umut doctor operated on me and I regained my health. Last year, the liver scared us, but our doctor Umut Rıza arrived immediately. May God bless him. Please go with your eyes closed and have the surgery done without fear. My sick brothers and sisters reading this page. I am a retired teacher and I am 66 years old. May God not let such a good doctor go to another country. May our doctor Umut Rıza live long.

He is a very successful, experienced and excellent DOCTOR. A very valuable, friendly, rare and valuable doctor who takes care of his patients not only during the treatment process but also after, clears the question marks in his patients’ minds, and is with them psychologically.

Thanks to your incredible skill, dedication, and care, my life has completely transformed after bariatric surgery. You are not just a doctor to me—you are one of the most important people in my life.From our first meeting, you made me feel confident and safe, and throughout the entire journey, your professionalism and support were truly remarkable. Because of you, I now have a second chance at life, filled with health, energy, and happiness.

Dr. Umut Rıza changed my life! We met in 2020. Afterwards, I became an oncology patient and contracted breast cancer. The doctor operated on me like a jeweler! My chest was protected and the stitches were not visible. The important thing was that I started to heal. Then I received hormone therapy, starved all the time, and gained a lot of weight. I contacted someone I trusted and explained my problem! Umut Rıza recommended me bariatric stomach reduction surgery! I agreed immediately because I trust him 100%! Umut Rıza is a top doctor! Such doctors are all in one hand! Believe me, I’m a doctor too! And what a great team working with the doctor! Everyone was attentive and polite, I was constantly taken care of! The nurses were very positive and professional! It’s magic! My surgery went perfectly! I lost 40 kilos! I started to look younger than my age! I feel like I’m 30, but I’m 53! I recommend everyone who has overweight problems to get help; Umut Rıza, an excellent expert, and his professional team will help you! I have only one piece of advice: Don’t buy too many plus size clothes!!! You will have to throw them away! I wish my wizard good health and long life! Doctor Umut Rıza, you gave me a new life! Thank you and God bless you! 🙏🙏🙏♥️♥️♥️
