Bronchitis is an inflammation of the lining of your bronchial tubes, which carry air to and from your lungs. Bronchitis may be either acute or chronic.
Symptoms
Symptoms of acute bronchitis usually begin 3 to 4 days after an upper respiratory infection, such as a cold or influenza (flu). Symptoms usually include:
A cough, which is the main symptom of acute bronchitis. It may be dry at first (does not produce mucus) and after a few days may bring up mucus from the lungs (productive cough). The mucus may be clear, yellow, or green. Sometimes, small streaks of blood may be present.
A mild fever, usually less than 101°F (38.3°C). A higher fever may indicate pneumonia.
A general feeling of tiredness.
A sensation of tightness, burning, or dull pain in the chest under the breastbone that usually is worse when breathing deeply or coughing.
Whistling noises (wheezing) when breathing, especially during physical exertion.
Hoarseness.
Causes:
A common condition, acute bronchitis often develops from a cold or other respiratory infection. Chronic bronchitis, a more serious condition, is a constant irritation or inflammation of the lining of the bronchial tubes, often due to smoking.
Treatment Overview
Treatment for acute bronchitis in otherwise healthy people usually includes taking steps to reduce cough, fever, and pain. Prescription medicines, such as antibiotics, generally are not beneficial. If you already have a disease, such as chronic obstructive pulmonary disease (COPD), heart failure, or asthma, evaluation and treatment may be more extensive.
Most cases of acute bronchitis go away in 2 to 3 weeks, but some may last more than 4 weeks. Home treatment to relieve symptoms is usually all that is necessary.
Medications
Most cases of acute bronchitis in otherwise healthy people go away in 2 to 3 weeks. You generally only need nonprescription medicines to treat your symptoms. Most people do not need to use prescription medicines, such as antibiotics.
