Acute bronchitis is swelling and inflammation of the main air passages to the lungs. This swelling narrows the airways, making it harder to breathe and causing other symptoms, such as a cough. Acute means the symptoms have only been present for a short time.
Acute bronchitis almost always follows a cold or flu-like infection. The infection is caused by a virus. At first, it affects your nose, sinuses, and throat. Then it spreads to the airways leading to your lungs.
Sometimes, bacteria also infect the airways. This is called a secondary infection.
Chronic bronchitis is a long-term condition. To be diagnosed with chronic bronchitis, you must have a cough with mucus most days of the month for at least 3 months.
The symptoms of acute bronchitis may include:
Even after acute bronchitis has cleared, you may have a dry, nagging cough that lingers for 1 to 4 weeks.
At times, it may be hard to know whether you have pneumonia or only bronchitis. If you have pneumonia, you are more likely to have a high fever and chills, feel sicker, or feel short of breath.
The health care provider will listen to your lungs with a stethoscope. Abnormal, coarse breathing sounds may be heard.
Tests may include:
Most people DO NOT need antibiotics for acute bronchitis. The infection will almost always go away on its own within 1 week. Take the following steps to get relief:
Certain medicines that you can buy without a prescription can help break up or loosen mucus. Look for the word "guaifenesin" on the label.
If your symptoms do not improve, your doctor may prescribe an inhaler to open your airways if you are wheezing.
Sometimes, bacteria may also infect the airways along with the virus. If your doctor thinks this has happened, you may be prescribed antibiotics.
Other tips include:
Symptoms usually go away in 7 to 10 days if you do not have a lung disorder. However, a dry, hacking cough can linger for a number of months.
