Browsing: Bronchitis

Bronchitis is a respiratory illness that can be caused by viral or bacterial infections, and it is characterized by inflammation and narrowing of the bronchial tubes. It is often associated with other respiratory illnesses such as asthma, chronic obstructive pulmonary disease (COPD), and pneumonia. People with bronchitis are at risk of developing these other respiratory illnesses and vice versa.

Acute bronchitis is caused by viral or bacterial infections and exposure to irritants such as pollution or smoking, which can lead to inflammation and narrowing of the bronchial tubes. Risk factors include smoking, exposure to pollution, and a weakened immune system.
