Former smoker. Recently got cleared as not a heart problem with tests like d dimer, bnp,
lipid profile. Also cleared 2d echo. Pulmonologist confirmed no lung issue with pft.. inhaler hasnt helped a bit. I feel extremely full after eating, laying down after eating. Feeling short of breath when walking and have to force expand top part of stomach to get air. Do you advise exploring this issue with a gastroenterologist? Or pls advise next tests..
