Cough
Those people with heartburn often suffer from a constant and unexplained cough, especially when they are lying or sleeping at night. The main reason is that acid in your stomach refluxes and reaches your lungs, thus causing inflammation around these areas. The most effective way to know this is to have a pH test from our doctor. In worse cases, stomach acid could even be aspirated into your lungs and airways and make it more difficult to breathe, especially for those people with asthma. [6]
