Effective Methods for Treating Bronchitis

Acute bronchitis is an infection of the major bronchial tubes that lead to infection of the lungs. It usually caused by the cold or flu virus, when your immune system is weakened and your lungs are already irritated. Acute bronchitis is most often caused by a virus, frequently the same one that causes colds, although the flu virus is a common culprit as well. (While acute bronchitis can also be caused by a bacteria or even a fungus.) Acute bronchitis is often followed by a cold or the flu health condition, when resistance is down and the lungs may already be slightly irritated. Likewise, anyone whose immune resistance is low or who has any other type of chronic lung irritation or injury, especially from exposure to cigarette smoke or other toxic gases, is at increased risk of developing bronchitis. Chronic bronchitis is often caused as a result of cigarette smoking, health allergies and air pollution.
