Hi ! I’m three months post opp and for the last week I haven’t been able to keep anything down.I throw everything up almost immediately.Any ideas on what this could be ? Please help!

If you are eating slowly, not drinking too soon after, not over spiced and foods you have eaten before, then i think you should get some medical help. I have gone through similar but mine was a Strictured RNY pouch with ulcerations in my jejunem- 2nd part of small intestine. I don't believe VSG stricture that much. Of course there is nothing in life impossible, but less likely.
