Is flushing okay if you have acid reflux?

My dad is interested. He is 62, but has GERD. Takes no meds for it, so no worries about neutralizing his pills as he don't take them. I would think that he should not do it, that it would cause him a nasty though temporary problem, like to vomit or something. That is not so bad. He is healthy but for the GERD. No ulcers mor anything like that. I just wonder if it wuld be likely to cause anything worse than puking in some eon with acid reflux.

Does anyone here that has flushed have GERD? I would love to hear from you about it, if so. Dad belches so bad every night. I know that you can hear himn five bloks away, if he is outside. Only three blocks if he is in the house. Sounds like a sick cow.

Thanks again.
