My 35 old daughter is very stressed at present as she has had acid reflux for several months. Following referral by her GP she had an endoscopy in March and the result was Grade C Oesophagitis. She was put on 40mg Omeprazole which has not helped followed by Ranitiding 350mg which again has not helped either. Her concern is genuine as I had an oesophagectomy to remove a tumuor 2 years ago and also her Grandmother died from cancer of the oesophagus some 20 years ago. Has anyone had a similar experience and how serious is oesophagitis?
