hi again ,, guys i am 20 years old male bodybuilder ,, i have anxiety for 9 months right now all the day and shortness of breath also all the day . i went to cardiologist and did echo test and cbc and tsh and 5 ECG's all came back good . also i did lung test and it was good and O2 was 98 every time i did the test . so what can cause my shortness of breath all day and all what i think of is my breathing .
Anxiety can and will cause this, also when you notice it naturally you pay attention to this which causes yet more anxiety. it is a vicious circle. I am exactly the same and have worried so much over the last year I am now on anti deppresants (sertraline) and also take diazepam as and when it is needed. these help but are not a miracle cure, myself I have gained weight and also the tablets make me sweat more but I tend to ignore it now and get on with life best I can. I have had ECG’s, chest X-Rays, blood tests and have a cardiology appointment next month.
Anxiety causes shortness of breath. When my anxiety is hi i have the same issues. Ive had all the same test as you too. Try breathing with your stomach with your mouth closed. It helps ti control that “need” for a deep breath and that feeling of being short winded.
