Acute bronchitis

Condition Overview:

Acute bronchitis is an infection of the bronchial (say: “brawn-kee-ull”) tree. The bronchial tree is made up of the tubes that carry air into your lungs. When these tubes get infected, they swell and mucus (thick fluid) forms inside them. This makes it hard for you to breathe.

Acute bronchitis is almost always caused by viruses that attack the lining of the bronchial tree and cause infection. As your body fights back against these viruses, more swelling occurs and more mucus is made. It takes time for your body to kill the viruses and heal the damage to your bronchial tubes.In most cases, the same viruses that cause colds cause acute bronchitis. Research has shown that bacterial infection is a much less common cause of bronchitis than we used to think. Very rarely, an infection caused by a fungus can cause acute bronchitis.

The viruses that cause acute bronchitis are sprayed into the air or onto people’s hands when they cough. You can get acute bronchitis if you breathe in these viruses. You can also get it if you touch a hand that is coated with the viruses.If you smoke or are around damaging fumes (such as those in certain kinds of factories), you are more likely to get acute bronchitis and to have it longer. This is because your bronchial tree is already damaged. Most cases of acute bronchitis will go away on their own after a few days or a week. It's a good idea to get plenty of rest, drink lots of noncaffeinated fluids (for example, water and fruit juices) and increase the humidity in your environment. Because acute bronchitis is usually caused by viruses, antibiotics (medicines that kill bacteria) usually do not help. Even if you cough up mucus that is colored or thick, antibiotics probably won’t help you get better any faster.

If you smoke, you should cut down on the number of cigarettes you smoke, or stop smoking altogether. This will help your bronchial tree heal faster.
