To begin with, if you are taking PPIs of any variety (which I am) that medication itself can make you nauseous, when, of course, they are intended to deal with G.E.R.D. while stopping glands in the stomach from producing acid.
I don't know whether or not you have had a cholecystectomy (which I did 10 years ago) but things have never been the same as far as digestion is concerned.
I was never recommended to take ox bile salts after the surgery since I never had unending diarrhea as some other patients have but some doctors recommend it for digestion after gallbladder removal no matter what. I did try digestive enzymes for a short while but since the doctors keep pushing the PPIs on account of diagnosed Barrett's esophagus diagnosis I was almost afraid to compromise the effects of the omeprazole.
I will tell you, however, that I believe and many other people do as well that the reason one gets G.E.R.D. first and foremost is that one's stomach does not have ENOUGH acid and therefore the extra amount of churning etc. that the stomach has to do to digest now causes what acid that one does have to be splashed upward since the food is not being moved along as it did before the surgery. I drink a small amount of Coca cola once in a while and I can tell you that every time I drink it I fell 100% better afterward, This would leave me to believe that the omeprazole I take is working against my self-interest.
I plan to discuss this with my primary and gastro after another EGD and ultimately will become my own guinea pig since none of the doctors I have seen heretofore seem to be able to help me feel better. I have also been diagnosed with eosinophilic asthma which appears to be related to food allergies and digestion.
Do you have any of these problems as well?
