Hello, sorry to hear about your boyfriends
stomach problems. I also have
bile reflux, but not to the point of
vomiting like this.
It sounds like he is over producing bile also...? If the doctor gave him any medication for the H. Pylori, is he still taking it? If not maybe another round of it would help. Also, they can prescribe Regalin or Metacopamide , for short periods. It helps the bile go down into the small intestine instead of coming back into the stomach.
