What kind of doctor treats Bronchiectasis?
A pulmonologist, a doctor who treats lung diseases, usually leads the care for bronchiectasis. Many patients also work with a respiratory therapist, a specialist who teaches ways to clear mucus from the lungs. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is bronchiectasis?
Bronchiectasis is a lung disease in which the large airways, the tubes that carry air in and out of the lungs, get damaged. The damage makes the airways permanently wider. They become loose and scarred, so they have trouble clearing the mucus they make. Mucus that stays in the lungs lets bacteria grow easily. This leads to repeated lung infections, and each infection damages the airways more.
Bronchiectasis can affect one section of a lung or many sections of both lungs. It is often linked with other lung conditions. There is no cure for bronchiectasis. But most people can manage it and have a good quality of life.
Symptoms
A long-term cough with large amounts of foul-smelling mucus is the main symptom. Symptoms develop over time, often months or years after the damage that caused the condition. Other signs include:
- Shortness of breath that gets worse with exercise.
- Wheezing, a whistling sound when you breathe.
- Coughing up blood.
- Fatigue, or feeling very tired.
- Weight loss.
- Bad breath.
- Low-grade fever and night sweats.
Causes and who gets it
Bronchiectasis is often caused by inflammation or an infection of the airways that keeps coming back. Sometimes it begins in childhood after a severe lung infection. Breathing in a foreign object or food particles can also lead to it. Other causes include:
- Cystic fibrosis, a disease that causes thick, sticky mucus to build up in the lungs.
- Primary ciliary dyskinesia, an inherited disease that affects the tiny hairs that clear mucus from the airways.
- Autoimmune disorders, such as rheumatoid arthritis, in which the immune system attacks the body.
- Immune deficiency syndromes, which weaken the body's defenses.
- Allergic lung diseases, such as a reaction to the Aspergillus fungus.
- Asthma or chronic obstructive pulmonary disease (COPD), which are not common causes.
How doctors diagnose it
The doctor starts with a medical history and a physical exam. With a stethoscope, a tool for hearing sounds inside the body, the doctor may hear clicking, bubbling, or wheezing sounds in the lower lungs. Tests may include a chest X-ray and a chest CT scan, which takes detailed pictures of the lungs. Other tests are a sputum culture, which checks the mucus for bacteria, blood tests, and lung function tests, which measure how well you breathe. Genetic testing, including a sweat test for cystic fibrosis, may be done.
Treatment
Treatment aims to treat infections, remove mucus, and prevent the problem from getting worse. Oral antibiotics are often the main treatment for repeated lung infections. Inhaled antibiotics may be used for a long-lasting infection. Bronchodilators, medicines that relax the muscles around the airways, help open them. Expectorants and mucus thinners make mucus easier to cough up. Inhaled corticosteroids, which treat inflammation, are used only when asthma or COPD is present.
Drinking plenty of water keeps mucus moist and easier to cough up. Chest physical therapy uses gentle pounding on the chest and back to loosen mucus. Airway clearance devices include a vibrating therapy vest, a small handheld device you breathe out through, and a mask that makes vibrations. If no other treatments help, surgery may remove a damaged part of the airway. In very rare severe cases, a lung transplant may be recommended.
When to see a doctor
See a doctor if the mucus you cough up changes color or amount. Get help right away if symptoms get worse or do not improve with treatment. Call 911 or go to the emergency room if you have chest pain, shortness of breath that gets worse, or you cough up blood.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. This kind of doctor can evaluate a long-term cough, track your symptoms over time, and refer you to a pulmonologist. They can also help coordinate follow-up care between your specialists.
Common questions
Is bronchiectasis curable?
No, there is no cure right now. But most people can manage the condition with treatment. Clearing mucus from the lungs, exercising, and lowering the chance of lung infection all help.
Can bronchiectasis be prevented?
You can lower your risk by treating lung infections promptly. Childhood vaccines, a yearly flu vaccine, and COVID-19 vaccines help reduce the chance of some infections. Avoiding smoking and pollution may also help.
Why does mucus build up in the airways?
Damaged airways lose their ability to clear out mucus. The mucus that stays behind lets bacteria grow. That causes infections, which damage the airways even more and create a cycle that is hard to break.
When is surgery needed?
Surgery may be an option if medicine does not work and the disease is in a small area of the lung, or if there is a lot of bleeding. A lung transplant is only for very rare, severe cases.
