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!

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.
