Lately, whenever I eat, the food tends to come back into my mouth after a little while, and I either spit it out or swallow it again. This happens more during dinner. For the last 2-3 days, Ive also been feeling a bit of chest congestion and slight breathlessness, which seems to be causing me to yawn frequently. What could be going on?

.i understand your concern...try eating several small meals instead of three large ones whenever you can...Avoid foods that irritate your stomach, especially those that are spicy, acidic, fried or fatty... avoid coffee,tea etc... Avoid stress,consider calming activities, such as meditation, yoga etc...sleep with head raised position and have dinner at least 2 hours before sleep..do regular exercises...take pantaprazole 40 mg twice daily before food with above
