I'm a 30 year old female, moderately healthy and active lifestyle. But I've always had a bit of a breathing issue. I can get out of breath very
easy- walking up a flight of stairs and I'm struggling to talk normally. But I am very active and recently completed a 10km race and exercise
Every now and then while in active I feel short of breath, my heart races a little (not usually over 100bpm) and I find my self taking additional large, sighing, breaths.
It's never been severe or debilitating, but recently I've been really wondering that it does not seem normal. Does anyone know what it might be? Or could it be serious?
