Thank you for your kind feedback.
It was an unsatisfactory visit because the Moviprep hadn’t worked properly, despite me not having eaten solid food for 36 hours. The consultant couldn’t see what he was doing in part of the bowel and has suggested that I should return in six months, making this colonoscopy extremely expensive.
"Thank you for your positive rating and for highlighting your positive experience with me. It was unfortunate that the bowel preparation was unsatisfactory despite your best efforts; I shall share your feedback with the pre-assessment and endoscopy teams to help us refine our protocols and prevent this from happening in the future. We would welcome the opportunity to discuss this with you directly to ensure your follow-up is as smooth and supportive as possible."
My first consultation regarding Diagnosis Reflux issue
Thank you for the feedback. Much appreciated
I have seen Mr Rajendran 3 times over the last 6 months & he has been very professional and attentive throughout. I recently had an appointment & took my sister with me and he explained everthing to us & was very kind. I cannot fault him & would highly recommend.
Thank you so much for your incredibly kind review. I am delighted to hear that you felt well-supported. It was a pleasure to meet both you and your sister recently.

Thank you for your kind feedback. Much appreciated
I went into The London Clinic for a Gastroscopy and Colonoscopy under general anaesthetic. I was quite anxious when I first arrived in the theatre ward as I had a migraine and also had to walk a long way and ascend a busy lift from my room to the theatre on the other side of the hospital and I had been fasting for 24 hours at that point. Dr Rajendran visited me before the anaesthetic and he was very patient and kind and spent a lot of time with me explaining what to expect, he made me feel calm and relaxed. After the procedure he visited me once I had woken up and explained what he had found. I then had a follow-up telephone call with him a few days later where he was again very patient and able to explain everything to me in great detail. It is very much appreciated. Thank you.
Thank you very much for your kind feedback. I am glad to hear that you felt comfortable during the whole process. It was a pleasure to look after you, and the experienced endoscopy team at The London Clinic also played an important part in ensuring everything went smoothly.
I received great support from Dr Rajendran. Would highly recommend him.
Thank you for your kind feedback. Much appreciated

Achalasia
Struggling with achalasia Achalasia is a rare condition that affects the oesophagus, making it difficult to swallow as the muscles fail to relax properly. This prevents food and liquids from moving easily into the stomach, leading to symptoms such as chest pain, regurgitation, and persistent swallowing difficulties. While the exact cause of achalasia is unknown, it is often linked to the loss of nerve cells in the oesophagus.

Barretts Oesophagus
Barrett’s oesophagus occurs when the cells lining the oesophagus undergo abnormal changes, often due to chronic acid reflux (GORD). This condition is a known risk factor for oesophageal cancer, though the likelihood of cancer developing remains relatively low. However, untreated acid reflux can lead to the advancement of Barrett’s oesophagus, potentially increasing the risk of cancer. Early diagnosis and treatment can effectively manage the condition.
