My question concerns my 102 yr. old mother. She has a pacemaker, is currently on Pradaxa, and is doing well, except occasionally when she trys to eat, phlegm fills her throat and she cannot swallow. She may spit up a little, but only clear phlegm, not stomach contents. At first I thought it was just dairy, and give her lactaid milk and/or tablets. Tonight, it happened with just a bite of baked potato.
