I have Gerd, Esophogitis,IBS,Lactose Intolerance and Hiatal Hernia . Oh man what a mess LOL !!!! I take kapidex, Bentyl , Alkaline Drops( acid neutrilizer) and Carafate. Recently I have been throwing up stomach acid , have a foul taste in my mouth with nausea and coughing up stomach acid too. My Pulmonologist said that the acid reflux can back up into your lungs if you are overweight with a Hiatal Hernia which I am. My Gastroenterologist does not think at this time that I require surgery to fix my Hernia. I am on alot of other prescription medications for other health reasons too, which I must take. I had all the test already Upper and Lower GI Series, Endoscope and Fluroscopy. I think I need to have my PH levels checked and plan to ask my Dr. to do so. If anyone else is experiencing something similar your imput would be greatly appreciated.
