Bronchiectasis

What Is Bronchiectasis?

Bronchiectasis is when the walls of your bronchi, the tubes that carry air into and out of your lungs, become thickened and damaged.

This makes it harder to breathe. You could have flare-ups of severe breathing problems (your doctor may call them exacerbations) from time to time.

Bronchiectasis is a long-term (or chronic) disease that gets worse over time. There’s no cure, but you can live with it for a long time.

Bronchiectasis Symptoms

Coughing and shortness of breath are common symptoms of bronchiectasis. Others include:

Bronchiectasis Causes

Your bronchial walls can slowly get thicker because of inflammation and infections. Both of these things keep mucus from draining the way it should. That extra mucus can trap bacteria, causing more infections, scarring, and thickening. Over time, your lungs have to work harder to breathe.

Acid reflux into your lungs, like with gastroesophageal reflux disease (GERD), may also damage them.

Bronchiectasis Risk Factors

Younger people don’t usually get bronchiectasis. Fewer than 1 in 20,000 people ages 18 to 34 have it. But that number goes up to about 1 in every 350 people who are 75 or older.

Two-thirds of bronchiectasis cases are in women. But it’s more common in young boys than in girls.

You’re more likely to get it if you have:

Bronchiectasis Diagnosis

See your doctor if you have symptoms of bronchiectasis, especially if you’ve had them for a while. They’ll probably order tests including:

  • A chest X-ray and CT scan to make images of your lungs
  • Blood tests to check for infections
  • Pulmonary function tests to measure how well you’re breathing
  • Tests of material that you cough up from your lungs, called sputum, which may have bacteria in it
  • A sweat test to look for cystic fibrosis
  • Bronchoscopy, in which your doctor uses a thin, flexible tube called a bronchoscope to look inside your airways

Bronchiectasis Treatment

Because bronchiectasis gets worse over time, it’s important to catch and treat it early. That will prevent infections, slow damage, and make your symptoms easier to manage.

Depending on your case, treatment for bronchiectasis can include:

  • Medications. You’ll probably get antibiotics to fight infections. One type, called macrolides (examples are azithromycin and clarithromycin), eases inflammation. Inhaled corticosteroids can also treat inflammation in your airways. Your doctor may prescribe medicine to thin mucus or help you cough it up (called expectorants). They might also give you an inhaler or a machine called a nebulizer to breathe in bronchodilators, drugs that open your airways.
  • Vaccines. Your doctor will probably suggest that you get flu and pneumonia vaccinations to keep certain infections at bay.
  • Oxygen therapy and chest physical therapy. They may also suggest oxygen therapy or methods and devices to shake mucus free. These treatments are known as chest physical therapy (CPT), chest clapping, or percussion. They can include physically pounding on your chest to clear your bronchi and lungs, or wearing an inflatable vest that uses air waves to force mucus up.
  • Surgery. In severe cases, you might need to have surgery or a lung transplant.

Bronchiectasis Prevention

Some steps help prevent the infections and tissue damage that can lead to bronchiectasis.

  • Get treatment for any lung infection as soon as possible.
  • Make sure children get recommended vaccinations for illnesses like whooping cough and measles.
  • Keep an eye on small children to keep them from putting things in their mouth. Get help right away if someone’s airways are blocked.
  • Avoid things that can damage your lungs, like smoke and chemicals.

Bronchiectasis Outlook

At some point, you’ll have to deal with an exacerbation, when your condition gets worse. You may have:

  • More phlegm
  • Different color of phlegm
  • Blood in your phlegm
  • Nagging cough
  • Stronger cough
  • Tougher breathing
  • Heavy fatigue
  • Chest pain

It’s important to talk with your doctor, who may prescribe medicines or other treatments that can open your airways.

Bronchiectasis is serious. But you can manage it if you listen to your body -- and your doctor.

Living With Bronchiectasis

You can live better with bronchiectasis if you take steps to make your lungs healthier and ease flare-ups:

  • Take medicines as your doctor prescribes them.
  • Get lung infections treated.
  • Avoid harmful fumes and gases.
  • If you smoke, stop.
  • Drink plenty of fluids to help thin mucus.
  • Exercise.
  • Eat a healthy diet.
