Acute Bronchitis, Adult

Acute bronchitis is sudden inflammation of the main airways (bronchi) that come off the windpipe (trachea) in the lungs. The swelling causes the airways to get smaller and make more mucus than normal. This can make it hard to breathe and can cause coughing or noisy breathing (wheezing).

Acute bronchitis may last several weeks. The cough may last longer. Allergies, asthma, and exposure to smoke may make the condition worse.

What are the causes?

This condition can be caused by germs and by substances that irritate the lungs, including:

  • Cold and flu viruses. The most common cause of this condition is the virus that causes the common cold.

  • Bacteria. This is less common.

  • Breathing in substances that irritate the lungs, including:

    • Smoke from cigarettes and other forms of tobacco.

    • Dust and pollen.

    • Fumes from household cleaning products, gases, or burned fuel.

    • Indoor or outdoor air pollution.

What increases the risk?

The following factors may make you more likely to develop this condition:

  • A weak body’s defense system, also called the immune system.

  • A condition that affects your lungs and breathing, such as asthma.

What are the signs or symptoms?

Common symptoms of this condition include:

  • Coughing. This may bring up clear, yellow, or green mucus from your lungs (sputum).

  • Wheezing.

  • Runny or stuffy nose.

  • Having too much mucus in your lungs (chest congestion).

  • Shortness of breath.

  • Aches and pains, including sore throat or chest.

How is this diagnosed?

This condition is usually diagnosed based on:

  • Your symptoms and medical history.

  • A physical exam.

You may also have other tests, including tests to rule out other conditions, such as pneumonia. These tests include:

  • A test of lung function.

  • Test of a mucus sample to look for the presence of bacteria.

  • Tests to check the oxygen level in your blood.

  • Blood tests.

  • Chest X-ray.

How is this treated?

Most cases of acute bronchitis clear up over time without treatment. Your health care provider may recommend:

  • Drinking more fluids to help thin your mucus so it is easier to cough up.

  • Taking inhaled medicine (inhaler) to improve air flow in and out of your lungs.

  • Using a vaporizer or a humidifier. These are machines that add water to the air to help you breathe better.

  • Taking a medicine that thins mucus and clears congestion (expectorant).

  • Taking a medicine that prevents or stops coughing (cough suppressant).

It is notcommon to take an antibiotic medicine for this condition.
