Bronchiectasis is a chronic lung condition that affects the airways, the tubes that carry air in and out of the lungs. It causes the airways to become permanently widened and damaged, making it hard to clear mucus and bacteria from the lungs. This can lead to repeated infections, inflammation, and scarring of the lung tissue. Bronchiectasis is irreversible, meaning it cannot be cured, but it can be managed with proper treatment and care.

ToggleWhat causes bronchiectasis?
Bronchiectasis can be caused by various factors that injure the walls of the airways or prevent them from clearing mucus. Some of these factors are:
- Recurrent or severe lung infections, such as pneumonia, tuberculosis, or fungal infections. These can damage the airway walls and make them more prone to widening and inflammation.
- Airway obstruction, such as by a foreign object, a tumor, or a blood clot. This can block the airflow and cause mucus to accumulate in the airways.
- Genetic or immune disorders, such as cystic fibrosis, primary ciliary dyskinesia, or immunodeficiency. These can affect the production or clearance of mucus, or the ability to fight infections.
- Allergic reactions, such as to a fungus called aspergillus. This can cause inflammation and scarring of the airways.
- Environmental exposure, such as to toxic chemicals, smoke, or pollution. This can irritate and inflame the airways.
Sometimes, the cause of bronchiectasis is unknown. This is called idiopathic bronchiectasis.
What are the symptoms of bronchiectasis?
The most common symptom of bronchiectasis is a persistent cough that produces a lot of phlegm (sputum). The phlegm may be clear, yellow, green, or bloody, depending on the type and severity of infection. Other symptoms may include:
- Shortness of breath or difficulty breathing
- Wheezing or chest tightness
- Fatigue or weakness
- Fever or chills
- Weight loss or poor appetite
- Bad breath or a foul-smelling sputum
- Recurring chest infections that require antibiotics
- Complications, such as lung abscess, pneumonia, or respiratory failure
The symptoms of bronchiectasis may vary from person to person, and may worsen during flare-ups (exacerbations). Flare-ups are periods when the symptoms become more severe, usually due to an infection or a trigger, such as cold weather, stress, or pollution.
How is bronchiectasis diagnosed?
To diagnose bronchiectasis, your doctor will ask you about your medical history, your symptoms, and your exposure to possible causes. Your doctor will also examine your chest and listen to your lungs with a stethoscope. You may need to do some tests, such as:
- Sputum culture, to check for bacteria or fungi in your phlegm
- Blood tests, to check for signs of infection, inflammation, or immune disorders
- Chest X-ray, to look for abnormalities in your lungs
- High-resolution computed tomography (HRCT) scan, to get a detailed image of your airways and lung tissue
- Lung function tests, to measure how well your lungs work
- Bronchoscopy, to look inside your airways with a thin, flexible tube and a camera
How is bronchiectasis treated?
There is no cure for bronchiectasis, but there are treatments that can help you manage your condition and improve your quality of life. The main goals of treatment are to:
- Clear the mucus from your lungs and prevent it from building up
- Treat the infections and reduce the inflammation in your airways
- Prevent or treat the complications and slow down the progression of the disease
- Relieve your symptoms and improve your breathing
The treatment options may include:
- Airway clearance techniques, such as chest physiotherapy, breathing exercises, or devices that help you cough up the phlegm
- Medications, such as antibiotics, bronchodilators, corticosteroids, or mucolytics, that you can take orally, inhale, or nebulize
- Vaccinations, such as for influenza and pneumococcal disease, to protect you from common respiratory infections
- Oxygen therapy, if your blood oxygen level is low
- Surgery, in rare cases, to remove the damaged parts of your lungs or stop the bleeding from your airways
You may also need to make some lifestyle changes, such as:
- Quitting smoking, if you smoke, and avoiding secondhand smoke and other irritants
- Drinking plenty of fluids, to thin the mucus and keep yourself hydrated
- Eating a balanced diet, to maintain your weight and boost your immunity
- Exercising regularly, to strengthen your muscles and improve your circulation
- Getting enough rest and sleep, to help your body heal and recover
- Managing your stress and emotions, to cope with the challenges of living with a chronic condition
How can you live well with bronchiectasis?
Living with bronchiectasis can be challenging, but it is possible to live a fulfilling and productive life with the right treatment and support. Here are some tips to help you live well with bronchiectasis:
- Follow your treatment plan and take your medications as prescribed
- Monitor your symptoms and seek medical attention if they worsen or if you have a flare-up
- Keep a diary of your symptoms, medications, and triggers, to help you and your doctor track your condition and adjust your treatment
- Join a support group or a pulmonary rehabilitation program, to connect with others who have bronchiectasis and learn how to manage your condition
- Educate yourself and your family about bronchiectasis, to understand your condition and how to cope with it
- Be optimistic and hopeful, to maintain a positive outlook and a good quality of life
What are the outlook and prognosis for bronchiectasis?
The outlook and prognosis for bronchiectasis depend on several factors, such as:
- The cause and severity of bronchiectasis
- The frequency and intensity of flare-ups
- The response and adherence to treatment
- The presence and management of complications
- The overall health and lifestyle of the person
Some people with bronchiectasis may have a mild or stable condition that does not affect their daily activities or life expectancy. Others may have a severe or progressive condition that limits their physical and social functioning and reduces their quality and length of life. In general, bronchiectasis tends to worsen over time, especially if left untreated or poorly managed.
However, with early diagnosis, appropriate treatment, and regular follow-up, many people with bronchiectasis can achieve good outcomes and prevent or delay the deterioration of their condition. Some studies have shown that bronchiectasis can be reversed or improved in some cases, especially in children and young adults, or when the underlying cause is treatable or curable.
Therefore, it is important to seek medical attention if you have any symptoms of bronchiectasis, and to follow your doctor’s advice and treatment plan. By doing so, you can improve your lung health and live well with bronchiectasis.
