I'm 18 and of a perfectly healthy weight, but for the past 3 years, ive suffered with severe Acid Reflux. Ive tried and tested many medications to relieve my severe symptoms of heartburn and food entering my esophagus, (with fail) and I have finally been booked in for an endoscopy as my Doctor suggested i may have a hiatus hernia. Although i am releived to be finally on my way to getting to the bottom of my problem, at present im having alot of trouble with my bowels. Whilst the heartburn medication i am on is helping, i feel as though i am excreting the acid when going the toilet. It is a very uncomfortable burning sensation when relieving my bowels, and i get stomach cramps as soon as i need the toilet. My stomach feels sensitive to everything, i.e food, drink, alcohol. I was wondering if this is an entirely different problem altogether like IBS (which my grandmother and father suffered with), or these symptoms are to do with my medication or acid problem?
