A lot of things can make you cough. Breathing in cigarette smoke, smelling a coworkers flowery perfume, or being sick with an infection can all leave you hacking. One of the infections that causes coughing is called bronchitis.

Bronchitis is inflammation in the airways that lead to the lung. If you've got bronchitis, there's a good chance you started out with a respiratory infection like a cold, and it spread to your lungs. Either a virus or bacteria can cause this infection.

The cough may clear up within a few days, but if it lingers for at least 3 months it's called chronic bronchitis. Chronic bronchitis is part of a group of lung diseases known as chronic obstructive pulmonary disease, or COPD for short. Smoking is one of the biggest causes of bronchitis and COPD.

If you have bronchitis, you'll cough, and cough, and cough. In fact, the cough can stick with you for weeks. When you cough, you may bring up a sticky goo called mucus. If the mucus is yellow-green in color, that makes us think it might be a bacterial infection. Other symptoms of bronchitis include chest pain, wheezing, shortness of breath, and fatigue.

To find out if you have bronchitis, your doctor will listen for crackly sounds in your chest when you breathe. You may also need a chest x-ray or other tests to see how well your lungs are working.

So, how is bronchitis treated?

Antibiotics won't treat bronchitis if a virus caused it, because they only kill bacteria. If you have a bacterial infection, you can take an antibiotic.

The best way to get over bronchitis are with rest and time. While your lungs are healing, drink plenty of fluids and perhaps use a humidifier to loosen up mucus. Whatever else you do, don't smoke or be around anyone who is smoking or smells like smoke. The smoke will only make your cough worse.

Bronchitis often clears up within a week or so, but the cough can stick around for weeks, or even months later, especially if you have a lung problem. While you're sick, call your doctor if you start to run a high fever, you feel short of breath or have chest pain, or your cough just won't go away.

You can help protect yourself against bronchitis by washing your hands often, getting a pneumonia vaccine, and getting a flu vaccine each year to prevent some of the diseases that cause it. Be kind to your lungs by staying far away from cigarettes. If you need help kicking the habit, see your doctor.
