Hello.
Thank you for asking at HCM.
With modern medicines, an
asthma patient should be able to do all routine activities, including exercise, sports and almost most of the things.
As you are having asthma since childhood, and you have difficulties in activities like walking upstairs or weight-lifting, I would suggest you controller medications for asthma. They are many, commonly used effective ones are inhaled
corticosteroids and
montelukast.
If used correctly, you will have a very good health and you will be able to carry out most of the daily activities without restriction.
As you have been told about "irregularity of lungs" & 54% function, I would also suggest to get
Spirometry with reversibility testing done. This test will help you and your physician to know more about your lungs.
Cough, breathlessness, feeling of lung contraction, breathlessness upon exercise, etc suggest that your asthma is not well controlled (I guess you don't have any other problems) which needs to be treated appropriately with controller medications.
So, don't worry.
Wish you best of the health.
Regards.
