Bronchitis is an infection of the upper respiratory tract in which the mucous membranes in the lungs’ upper bronchial passages become inflamed.
As the irritated membranes swell and grow thicker, it narrows the tiny airways in the lungs which results in coughing spells accompanied by thick phlegm and breathlessness. This condition is more common in the winter and comes in two forms: acute and chronic.
Acute bronchitis:
This type of bronchitis is responsible for the hacking cough and phlegm production that sometimes accompanies an upper respiratory tract infection. In most cases of acute bronchitis, which is very common among both children and adults, is caused by an infection of viral origin, but sometimes can be caused by a bacteria.
If you are in good health, the mucous membrane will return to normal after you have recovered from the initial lung infection, which usually last for several days. If the infection is caused by a bacteria you may need to see a physician; usually only 10 percent are caused by a bacteria.
Symptoms of acute bronchitis:
* hacking cough.
* yellow, white, or green phlegm, usually appearing 24 to 48 hours after a cough.
* fever, chills.
* soreness and tightness in chest.
* some pain below breastbone during deep breathing.
Chronic bronchitis:
This type is a serious long-term disorder that requires regular medical treatment. Chronic bronchitis results from frequent irritation of the lungs such as from exposure to air pollutants, cigarette smoke, and noxious fumes rather than from an infection.
People who have chronic bronchitis tend to be obese and lead sedentary lives, and most are heavy smokers, they typically have emphysema as well. The airway walls enlarge and the passageway narrows which makes breathing more difficult.
Symptoms of chronic bronchitis:
* persistent cough producing yellow, white, or green phlegm (for at least three months of the year, and for more than two consecutive years).
