Suddenly, without change in diet or behavior, I am getting mild heartburn after everytime I eat. What could cause this? What do I do to get this to stop?
I am 24 and I am not overweight. I have a normal BMI.

I have some chest tightness, which is making it feel like Im having difficult breathing could heartburn cause this? I also went to the hospital last week & they said bronchitis could be setting in but I also always have BAD heartburn could that also cause some of the chest tightness & feeling short of breathe?
