Is it normal to be out of breath having bronchitis?

Yes. It is perfectly normal to be out of breath, when having bronchitis. Bronchitis is a disease of the lung and it is where the bronchial tubes are irritated. It results in too much mucus being produced. Bronchitis is caused by smoking and if it continues, it can become Chronicc Bronchitis. In Chroni Bronchitis, the cilia are damaged and their ability to move mucus , bacteria and dirt particles is impaired. Thanks for asking this question cause it helped prepare for my test on the respiratory system.BTW ima 7th grader.
