What Causes Bronchitis?
Bronchitis occurs when there is an inflammation in the main passages to the lungs. There are two types of bronchitis: acute and chronic. Acute bronchitis is short-term, while chronic is ongoing.

Causes
-
Infections, such as colds or flu, can irritate your lungs and cause acute bronchitis. Other factors--including secondhand smoke, air pollution and dust--can increase your risk. Smoking is a major cause of chronic bronchitis.
Symptoms
-
The main symptom of acute bronchitis is coughing. Wheezing, low fever and chest tightness are also common. In severe cases, there may be shortness of breath. Signs of chronic bronchitis are wheezing, coughing, chest discomfort and mucus.

Who Is at Risk?
-
The elderly, infants and young children are at a higher risk of catching acute bronchitis. People of all ages can have chronic bronchitis, but it is most common in those over 45. People who smoke or have an existing lung disease, are at a higher risk of having bronchitis. People with jobs that require close contact with vapors, dusts and chemical fumes may also be more likely to have bronchitis.
Treatment
-
Fluids and aspirin constitute the main treatment for acute bronchitis. The goal is to relieve the symptoms to make breathing easier. A humidifier and/or steam may also help loosen mucus and relieve wheezing.
Prevention/Solution
-
You cannot prevent bronchitis, but you can take steps to lower your risk. The National Heart Lung and Blood Institute says that the most important step is to quit smoking (or just not start). Try to avoid lung irritants by wearing a mask over your face.
