Bronchiectasis is a type of chronic obstructive pulmonary disease (COPD) characterized by a persistent cough and recurrent lung infections. With bronchiectasis, you can experience a daily cough with thick sputum that doesn't improve or resolve on its own. You can also experience issues such as low energy and weight loss.

You may develop bronchiectasis as a complication of cystic fibrosis or recurrent lung infections. Because you may already have a history of respiratory illnesses before you experience the effects of bronchiectasis, it can be challenging to recognize bronchiectasis as a separate condition.

Persistent symptoms—even at times when you do not have an infection—can be a sign you've developed this serious and lasting respiratory complication.

Frequent Symptoms

When the bronchi and bronchioles (airways in your lungs) become wider than they normally should be—the main problem in bronchiectasis—mucus can build-up inside them. The cilia, tiny hairs that normally catch small particles in your lungs, also do not function well in bronchiectasis. Furthermore, the condition causes the airways to become obstructed. This can lead to a few notable symptoms.

Chronic Cough

A daily cough is the most common effect of bronchiectasis. With this condition, your cough is likely to be productive—which means that you will cough up sputum or, in rare instances, blood. A cough is your body's way of getting rid of mucus build-up when your lungs cannot get rid of it on their own.

In general, a cough that develops due to a viral infection should resolve within a few weeks. With bronchiectasis, the cough does not resolve on its own. That persistence is a clue that you could be dealing with an airway disease rather than a short-term infection.


Sputum, also described as phlegm, is composed of mucus, saliva, and/or dead cells or microorganisms (such as viruses and bacteria).

The sputum brought up by a bronchiectasis cough is likely to be thick, brownish or even blood-tinged, and copious. It can also be foul-smelling and cause bad breath.

The consistency, color, and smell of your sputum can change depending on factors such as whether you have an infection.

Rare Symptoms

In addition to a nagging, productive cough, you may also experience additional effects of bronchiectasis. The condition can have a severe effect on your ability to breathe, and you might notice changes in your fingers described as clubbing of the nails.


With bronchiectasis, you may experience hemoptysis (coughing up blood). This occurs when tiny blood vessels near the surface of bronchial tubes are torn, usually as a result of an infection or a violent cough.

The bleeding is likely to appear as brown or pink streaks in your sputum. If you cough up large amounts of blood, you need to get emergency medical care.


You can experience dyspnea (shortness of breath) when your airways become blocked with mucus. Typically, dyspnea worsens with exertion or exercise, especially when bronchiectasis is relatively mild in severity. As the disease progresses, you may have shortness of breath even when you are at rest.

Clubbing of the Fingers

Clubbing of the fingers and nails makes your nail bed curve down in a way that looks like an upside-down spoon. You can develop clubbing with lung diseases, digestive diseases, Graves' disease (a type of hyperthyroidism), and cancers such as Hodgkin's lymphoma.

When clubbing occurs due to a medical illness, it is believed to develop as a result of chronically low oxygen levels in the body.

Some people's fingers normally have an appearance similar to that of clubbing. A change in the normal appearance of your fingers could mean that you have bronchiectasis.


Wheezing is often described as a whistling sound heard during inhalation or exhalation. When you have bronchiectasis, your wheezing may be so loud it can be heard without a stethoscope.

Because wheezing occurs when your airways become narrow or blocked, it may be more noticeable when you have more mucus build-up than usual.


Over time, you may experience more widespread effects of bronchiectasis. The condition can have an effect on your overall health and well-being, and it is associated with a shortened life span.

Weight Loss

You may be surprised to experience unintentional weight loss. This can happen due to a loss of appetite that develops when you have a bad taste in your mouth. Additionally, bronchiectasis causes your body to consume more calories due to the physical demands of coughing and effortful breathing.

Fatigue and Weakness

Fatigue is an overall feeling of tiredness or lack of energy. It is the type of exhaustion that can't be overcome easily with a good night's sleep or caffeine. You can feel weak when you have bronchiectasis-associated fatigue.

The weakness caused by bronchiectasis affects the entire body (as opposed to localized weakness, which affects only a specific limb, muscle group, or one side of the body).

Lack of sleep caused by excessive coughing at night can make you feel very tired and weak during the day. Some of the medications you may need to to control your symptoms—such as antihistamines, blood pressure medicines, sleeping pills, steroids, or diuretics—can also cause fatigue.

Recurrent Lung Infections

Respiratory infections in bronchiectasis may precipitate a cycle of repeated inflammation, infection, and airway obstruction. Recurrent infections can lead to bronchiectasis, and bronchiectasis also predisposes you to recurrent lung infections.

Infections can also lead to fever and exacerbate hemoptysis, pleurisy, weight loss, fatigue, and generalized weakness.


Bronchorrhea is a symptom in which large amounts of thin mucus are coughed up from a person's lungs on a daily basis. This is not just a little drainage and can be an incredibly distressing symptom. This symptom can result in a persistent cough (to clear the fluid) and shortness of breath (due to obstruction of the airways by mucus).

When to See a Healthcare Provider

When you have bronchiectasis, you need to maintain regularly scheduled medical care. You also need to talk to your healthcare provider if your condition seems to be progressing.

Signs of Worsening Illness

See your healthcare provider if you have a fever, experience shortness of breath or pain with breathing, or see dark streaks in your sputum when you cough.

Weight loss and low energy can be caused by worsening bronchiectasis or by another medical condition, so getting a proper diagnosis is important.

Medication Side Effects

If you are having trouble sleeping, or if you feel dizzy or as if your heart is racing, you could be having a medication side effect. Let your healthcare provider know; a change in your prescription may alleviate these symptoms.

Emergency Issues

Serious respiratory emergencies can manifest with a number of sudden problems. Seek emergency care if you have:

  • Difficulty breathing
  • Severe or increased wheezing
  • Feeling as if you might lose consciousness or faint
  • Cyanosis (pale or blue fingertips or lips)
  • Coughing up blood (thin blood or more than 1/4 of a teaspoon)
  • Grunting noises when you breathe
  • Tachypnea (rapid, shallow breathing)

Frequently Asked Questions

  • What are the predominant symptoms of bronchiectasis?

    There are several symptoms that, when they occur together, lead a healthcare provider to suspect bronchiectasis:

    • A chronic cough that brings up large amounts of thick, brown or blood-tinged, foul-smelling sputum
    • Shortness of breath
    • Wheezing
    • Chest pain
    • Clubbing of fingernails and toenails
    • Recurrent respiratory infections
  • Is there such a thing as mild bronchiectasis?

    Yes, certain subtypes of bronchiectasis may not cause symptoms that are as severe as those associated with, say, cystic fibrosis. One of these is cylindrical bronchiectasis, which causes relatively less damage to the walls of the bronchi. There is even a form of bronchiectasis called traction bronchiectasis that may not cause symptoms at all because the mucosa of the airways are not affected.

  • What can trigger bronchiectasis symptoms?

    Bronchiectasis symptoms don't have triggers like allergies or asthma do. Instead, the damage to the airways is permanent and can have a number of causes. One of the most common is cystic fibrosis; others include infections, a compromised immune system, conditions such as rheumatoid arthritis and Crohn's disease, severe asthma caused by the Aspergillus fungus, and certain genetic conditions.

  • Is there a cure for bronchiectasis?

    In short, no: The damage to the lungs that causes bronchiectasis is irreversible. However, it can be managed. Early and aggressive treatment of bronchiectasis can slow the progression of the disease and prevent symptoms from worsening. It's important to note that people with bronchiectasis not caused by cystic fibrosis tend to have normal lifespans.
