Hello, A year back in March 2024 I did treadmill test and 2d echo cardiogram both were normal. 6 days back I did both the test but 2d echo was normal with mild pah value 40. I m healthy do exercise daily and underweight from a long time. Want to ask what could be the reason behind this mild pah out of no where as I don't smoke don't drink at all. I m getting married this year and am bit scared I have anxiety issues and acid reflux as well because of that I have mild difficulty in breathing. Not sure it is because of that or something else. Please if anyone can let me know that what could be the reason of mild pah and can it go down again and what reason can be there for increase in that mild pah what factors can be and what I should avoid doing and how I should take care of myself without medicines as currently no major issues are there.
