Hi dear SubbaRao ,
Welcome to HealthcareMagic.
In many people with
asthma , the person is allergic to a sustance and that initiates the reaction and so
cough ,
cold , breathlessness.The best way to treat is to find out the substance you are allergic to and stay away from it. When you have the episodes of cold and cough , approach for medical advise immediately and get treated promptly.
Asthma can be treated effectively by bronchodilators and
steroid inhaltional puffs which will be given by your Chest Physician.
If you are a smoker please try to
quit smoking.
Good luck .
Have a happy and Healthy life.
