Hi! For the past 5-6 mos I have occasionally experienced dry heaves during a bowel movement. I can t relate this to any particular food or activity. This happens maybe once a week, occasionally twice. I have also gone weeks without it occurring. I stopped taking probiotics because I had changed brands & it seemed to be better although I did have 1-2 episodes. I started taking a different brand of probiotics again and the problem has returned more frequently again. I had a colonoscopy & an endoscopy within the past 2 yrs and everything was fine. Is it possible that the probiotics are causing this problem? Thank you.
