HELLO, i can understand your concern. feel very sorry to know about your mother. an xray or ct scan of the chest is required to tell the exact condition of your mother. copd is a progressive disease which means it would definitely worsen with time. even after the medications she has been taking if she is breathless or has severe cough, tightness of chest even at rest this is not much of good news. sadly there are no drugs which can reverse the damage done already. life span would be very difficult to say as the condition worsens rather drastically and if accompanied with other chronic diseases like hypertension, diabetes the deterioration is much faster. hope i have answered your queries. wish her a speedy recovery and a longer life. thanks for choosing HCM
