Everything from the first initial consultation to 10 weeks post op have been amazing. Everything is explained well, he puts you at ease with any worries you may have and makes you feel valued, very impressed and very happy with how everything is going. Amazing Doctor with a great team Thank you very much for helping me get a life back, and start to enjoy exercise again. Forever grateful!
I found Mr. Andrei Ilczyszyn very helpful and communicative and he answered all of my questions in a way that I could understand. He was very reassuring and left me very confident in my treatment.
After suffering all my life with losing weight , putting it back on trying everything all I can say is how much a gastric sleeve has changed my life already 9 weeks post op and the care I received by the whole team was second to none my surgeon has changed my life the care from start to finish was unbelievable thank you so very much
From the very beginning, from having my consultation to post op with Dr Ilczyszyn he made me feel heard & seen! He explained everything very clearly for me to understand from telling me the process of the operation and the reasons of why I could have been struggling with weight loss for so long! I knew when I got off the phone with him that he would be the consultant I wanted to do my surgery. He came to see me on the morning of my surgery and made me feel right at ease. I knew I was in good hands. Following the procedure he visited me before discharge and told me how well the surgery went. He is so kind and caring and I feel he truly understood my struggles and wanted to help me. Whilst I was off of work, he was very easily contactable as I needed a letter from him for my place of work as I was struggling to get paid sick leave. He did this and made me feel as I wasn’t bothering him at all. I would recommend him to do anyones surgery and I will always be grateful of his support, kindness and sensitivity. I feel eternally thankful for the care he has given me. Thank you again! You’ve changed my life. 5 stone down and counting!

Thank you for the kind review, all the best for your weight loss journey and I am always available for any support
A really good experience - procedure very clearly explained
Mr Ilczyszyn is true gentleman. He was excellent at explaining what was going to happen and how you will feel. He said he would be available should I need to ask anything .
He came to see me before the op, went though everything and checked i was still happy to go ahead. Came and checked in after surgery and the next day.

Thank you for the 5⭐️ review, all the best for you recovery

Thank you for the kind words, all the best for your recovery
Throughout my consultation I felt reassured that I was in ‘safe hands’. Despite my symptoms not appearing to be conclusive as to the issue, Mr. Ilczyszyn listened to my explanations and then provided clear options for treatment / moving forward which all made perfect sense.
Very clear explanation of what was to happen before the operation. A great explanation after the operation. Made me feel ver comfortable.
I remember Andrei as an excellent surgical trainee who has now become a pioneer in the fields of bariatric surgery and minimally invasive procedures. I would recommend him as superb consultant.
