Bronchitis is an inflammation of the bronchi (the air passages that extend from the windpipe into the lungs) which may be caused by viruses, mycoplasma, bacteria, smoking or inhalation of chemical pollutants or dust. The cells that line the bronchi have tiny hairs (cilia) that trap and eliminate pollutants. When these cells become overly irritated, they stop functioning. Consequently, the air passages become clogged by debris, and irritation increases. In response, a heavy secretion of mucous develops, which causes the characteristic cough of bronchitis.
Brief bouts of acute bronchitis may evolve from a severe cold or flu, but may also begin without having had an infection. If you have underlying asthma, bronchitis may precipitate an asthma attack. Even if you have no history of asthma, bronchitis may trigger some asthma-like symptoms, such as wheezing and shortness of breath. Smoking is frequently associated with chronic bronchitis.
Symptoms may include:
- a deep cough that produces yellowish or greenish phlegm
- pain behind the breastbone when you breathe deeply or cough
- low-grade fever or chills
- sore muscles
- Stop smoking! Click here for tips on quitting or cutting back on your smoking.
- Drink large amounts of fluids to help loosen up chest mucous and move it out of your body.
- If your room is dry, using a humidifier may help.
- Try to get enough rest and sleep. Your body needs to rest to help fight the infection.
- Guaifenesin (in plain Robitussin) is an expectorant which may help.
- Dextromethorphan (in Robitussin DM) is an effective cough suppressant which may be helpful to deal with a dry, hacking, “non-productive” cough.
- If antibiotics are prescribed by your medical provider, be sure to take all of the medication even if you feel better before you finish the medication. You may feel better before the infection is really gone, and stopping the medication will only leave the infection in your body.
- If a bronchodilating inhaler or pills are prescribed by your medical provider to open the air passages, be sure to follow the instructions you are given.
- It is important to return to Health Services or to call your provider if your symptoms become worse, if you develop a high fever (101°F or higher), or if you do not begin to improve within a few days. Symptoms usually last about 10 days.
- Contact your provider if at any point you feel you are too ill to care for yourself.
