Hello Dr Rynne...My mother is 88 years old, for the last 2 weeks she has been unable to keep her food down, spitting it up after a few minutes..she s lost about 5 lbs because of this...I got her some gaviscon thinking it might be gastric reflux, she s been taking it since saturday, she still regurgitates , but not as much as she has in the first 2 weeks...Any ideas? thank you....
