Hello, I can understand your concern. Shortness of breath can be mainly due to cardiac problems, lung problems/asthma or anxiety. I would advise you to rule out the important causes first by visiting a physician for physical examination and to rule out any cardiac or pulmonary problem including asthma. If those two are ruled out, you can be sure that anxiety is causing you catch your breath! You can then take appropriate treatment for cardiac or lung problem if found, or change your lifestyle to a little less stressful and try to relieve anxiety by anxiolytics. I hope this information helps. Thank you for choosing HCM. I wish you feel better soon! Best, Dr. Viraj Shah
