Re: multitude of things
This sounds a lot like Gerd/AR to me. I could be wrong, I'm not a Dr, but the Omeprazole your Dr has prescribed leads me to believe he is thinking along the same lines as me, This is a PPI which is generally prescribed for the above. I have the same problem myself.
Your Dr probably wants to see how you get on with this treatment. If it doesn't help, you may be reffered for an Endoscopy to see what is going on. Ive had three of them.
PPIs did not help me though other people seem to get on OK with them.
I changed my eating habits and I take Aloe Vera Digestive Aid juice which I feel has helped me. Probiotics are also good. For the Gas/Bloating, I eat small and often and take OTC Gaviscon. Do speak to your Dr again if there is no improvement. Good Luck, Solofelix.
