spitting up white fluid like substance or white foam

Hi,
I had a fundoplication done in May of 2015. When I started semi solids again after the surgery I was having problems with swallowing and sometimes I spit up a white fluid the consistency of a liquid yoghurt. Sometimes it is thick and foamy. I contribute this to reflux again but my doctors say my fundoplication is in place and my barium swallow did not show reflux, so the fluid must come from somewhere else. I had 3 scopes of my nose done and nothing. I was checked for congestive heart failure and everything checked out normal.
Is anybody here having these types of symptoms who suffers from reflux? It is really beginning to scare me.

Elke55. Our doctor called it "water brash". Type this in the above search engine-- I'm sure there are several entries about it - that may be helpful. Sorry, but the only thing I recall is that the body puts this out to neutralize acid-- I pray that you feel better quickly . Please pay attention to what you eat. That is most important. Our Doctor told us that having surgery does not mean that you can now eat whatever you want. He said to eat the way you should have been eating all along.. I wish you well. Kind regards. Pat
