Foam
Be sure to check with your surgeon's office, especially if you have dry heaves. My DH had this happen about a month after surgery - couldn't keep anything down and was dry-heaving or bringing up some foam. He had an ulcer. I am about 2 years out, and once in a while, I still get the foamies, but it's more like spitting up.

I have this problem all the time and I am 7 weeks post op. I can't burp so when I get gas in my chest this is the only way to get it out by vomiting and then it is all foam. The bad part is that when this happens.. I cannot eat or drink anything for the rest of the day because even a sip of water will bring the gas and foaming back. Hope all goes well with you! Wish I could be of more help.
