reflux treatment patient reviews
Acid reflux surgery - 2021 “Fantastic experience with everything fully explained from start to finish by Prof Viswanath. The tests and more importantly the surgery went incredibly well and the recovery came with no surprises. The end results have been life changing, I’m reflux and symptom free for the first time in 15 years and feel like a different person”
Hiatus Hernia surgery – Feb 2021 “Prior to my operation on 12th Feb 2021, I did not feel as if I was living but merely existing due to the pain and acid reflux I was suffering from. I had been given numerous amounts of medication although none of them went anywhere near controlling my symptoms. The impact on my health and well being has been enormous. I couldn’t even do every day exercises like walking or climbing stairs without being extremely breathless. Now I feel like I have been given a second chance at a normal life and I know that eventually I will be able to eat a more varied diet without having to worry about feeling ill. I only wish that I could have had the operation 10-20 years earlier! It’s the start of a new life thanks to Professor Viswanath”
Keyhole Surgery to repair a large hiatus hernia and laryngeal-pharyngeal symptoms - November 2019 "I am writing to thank Professor Viswanath and all of the staff who cared for me during my recent treatment at Nuffield Health Tees Hospital". I was admitted on November 7th for an operation to repair the hiatus hernia. The careful preparations by Prof. Viswanath and Dr Baker the anaesthetist, and the nursing staff ensured that I was very calm and confident before going to theatre. The surgery itself was very long and demanding on Prof Viswanath. It amazed me that he was able to correct such a large hernia laparoscopically. I was very fortunate to be in the care of such a skilled surgeon"
Diagnostic Study followed by Stretta therapy for GORD (Acid Reflux) "I have had problems for 8
years. Coughing initially, shortness of breath and indigestion, which gradually
became worse. I also had asthma symptoms 4 years ago which included wheezing,
hoarse voice and sinusitis. I saw an ENT physician who thought these
symptoms were caused by gastric reflux. In the last 4 years, I have had lung
function tests, lung scans, gastroscopies and pH manometry tests, which have
all proved inconclusive. My symptoms gradually became so bad that it was
making my life a misery. I was unable to continue with hobbies such as ballroom
dancing and I was so breathless that walking the dog was becoming a problem
too. My symptoms got that bad that I was wheezing just going upstairs! I was
prescribed steroids and an inhaler for the breathlessness and wheezing. I had
also been taking omeprazole for many years and when I had to stop taking this
prior to some procedures I suffered terrible indigestion, heart burn and chest
I researched gastric reflux and found an article about Professor Viswanath who performed a procedure called Stretta. I saw my GP about this procedure and he referred me to see Professor Viswanath at Nuffield Health Tees Hospital. My first appointment was in January 2019 where I was advised to have a gastroscopy and a Restech pH study to accurately diagnose my reflux condition. The results showed evidence of significant reflux. I decided to go ahead with the Stretta procedure, which was 6 weeks ago now, and the improvement in my symptoms is unbelievable! I am now sleeping better and not waking up at 5 am with terrible regurgitation and choking. My breathing is much improved and I am delighted to be back at ballroom dancing again. I am still coughing but not as much as I was and my voice is not as hoarse, which my friends and family have noticed.
I cannot thank Professor Viswanath enough; he has given me a new lease of life. Thank you so much."
Stretta Therapy for GORD with Laryngo-pharyngeal Reflux (LPR) "It has only been over the last two weeks that I have felt an improvement in my condition. These are not huge, but for me it has been significant and this has given me some hope that my condition will continue to improve. I am of the understanding that because I suffer from LPR (Laryngo-Pharyngeal Reflux) my symptoms will likely take longer to recover than standard GORD. Some reports state that improvement could take 6-12 months and beyond. Although early days, my standard of living has improved and this has helped me focus more on family life and work. I am optimistic and for that I would like to pass on my sincerest thanks to Professor Viswanath and his full supporting team. You have all made a difference to my life and the people in it!"
Groin Hernia Repair Patient Reviews
Inguinal (groin) Hernia Repair - Mar 2021"Having been diagnosed with an inguinal hernia, I was referred to Nuffield Tees under the care of Professor Viswanath, to have mesh inserted to rectify the problem. The operation took place on 25th March and from start to finish, I have nothing but praise for all the staff who attended to me during my brief stay. The nurses, porters, cleaners and kitchen staff could not do enough for me. I was treated with the utmost respect and care. I also cannot praise the anaesthetist and of course Professor Viswanath for their absolute professionalism and dedication to their work. The operation appears to have been successful and I am slowly recovering. I should also praise the excellent aftercare that I have received too! Please accept my eternal thanks for all your dedication and hard work."
Inguinal (groin) Hernia Repair – Feb 2021 "I would like to thank Professor Viswanath and all the staff at Nuffield Tees who cared for me. The whole process from pre-op to post-op care was of the highest standard. I would highly recommend Prof Viswanath, he is a very skilled surgeon"
Inguinal (groin) Hernia Repair – 2021 “1st rate. Did a superb job on repairing my inguinal hernia! Highly recommended”
Hernia Repair – 2020 “Covid precautions were comprehensive and I felt totally safe. All communication was excellent from Surgeon and secretary, aftercare from nurses and phone calls from nursing staff were clear and concise. I had a problem and rang for advice and advice given was really helpful and knowledgeable”
Inguinal (groin) Hernia Repair - 2020 “Professor Viswanath is a top surgeon and very experienced with hernia repair surgery, explained everything thoroughly before and after the operation. I felt very confident after consultation to put my faith in him. 6 weeks on now and my groin feels a lot better and can get back to normal life”
Hernia Repair - August 2019 "I had a hernia operation at Nuffield Health Tees Hospital in August 2019 and I would like to take this opportunity to thank all of the staff, both clinical and reception, for the lovely treatment I was given especially Prof Viswanath.
