I have been a consultant Gastroenterologist for over 23 years and as such have acquired a wealth of experience treating a wide range of gastroenterological conditions. I have a particular expertise treating heartburn/reflux/indigestion/stomach problems/dyspepsia/swallowing problems (dysphagia) and various bowel conditions such as constipation and diarrhoea. My approach is to take a detailed history and examination and in particular look at your diet to see what might be aggravating your condition (if that is relevant). I am an experienced endoscopist doing several hundred gastroscopies (stomach examinations) and colonoscopies ( bowel examsinations) per year. Further details can also be viewed on www.hertsgastro.com
