Bronchiectasis: Understanding the Condition, Its Causes, and New Treatment Options

By: Michael S. Alvarez, DO, MPH, FCCP


Treatment Options

If you have been told you have bronchiectasis, you may be wondering what it really means, what caused it, and what you can do about it. This chronic lung condition is not as widely recognized as asthma or COPD, but it is just as important to diagnose and manage properly. Let’s take a closer look at what bronchiectasis is, how it develops, how doctors diagnose it, and the modern treatment strategies—including new medications like brensocatib (Brinsupri)—that are changing the outlook for patients.

What Is Bronchiectasis?

Bronchiectasis is a disease where the airways in the lungs become abnormally widened, scarred, and damaged. In a healthy lung, the airways act like flexible tubes that carry air in and out while moving mucus up and out efficiently. In bronchiectasis, however, the airway walls lose their normal structure. They become floppy and scarred, mucus clearance is impaired, and secretions collect instead of being swept away. This stagnant mucus creates the perfect environment for bacteria to grow. Over time, repeated cycles of infection and inflammation cause even more airway damage. The result is a vicious cycle: damaged airways, mucus buildup, infection, inflammation, and more airway injury.

What Causes Bronchiectasis?

There are many possible causes of bronchiectasis. Sometimes, the exact cause is never found. It may occur after a severe lung infection, or in people with chronic lung diseases such as COPD, cystic fibrosis, or severe asthma. Immune system problems that make it harder to fight infections can play a role, as can recurrent aspiration or reflux, where food or stomach acid repeatedly enters the lungs. In other cases, rare genetic or structural problems with the airways are to blame.

Certain conditions are often seen alongside bronchiectasis and can make it worse. Two of the most important are nontuberculous mycobacteria (NTM), which are slow-growing bacteria that can cause chronic lung infection, and allergic bronchopulmonary aspergillosis (ABPA), an allergic reaction to a common fungus that drives inflammation and mucus plugging.

Recognizing the Symptoms

The symptoms of bronchiectasis can look very similar to other lung diseases, which is why it is often underdiagnosed. A chronic cough is almost always present, and patients often bring up mucus on a daily basis. Recurrent chest infections that require antibiotics are another hallmark, along with shortness of breath, wheezing, fatigue, and reduced exercise tolerance.

The best way to confirm bronchiectasis is with a CT scan of the chest, which clearly shows the widened and irregular airways. Other parts of the evaluation may include sputum cultures to check for bacteria or fungi, blood tests to evaluate the immune system, and pulmonary function tests to see how well the lungs are working.

Treatment Strategies

There is no cure that can reverse the airway damage once it has developed, but treatment can dramatically improve quality of life, reduce infections, and slow disease progression.

The cornerstone of management is daily airway clearance. Chest physiotherapy, special breathing exercises, and mechanical techniques such as oscillatory flutter devices or vest therapy help mobilize mucus. Inhaled saline solutions, especially hypertonic saline, can thin mucus and make it easier to clear.

Antibiotics are used both for acute flare-ups and, in select cases, for long-term suppression. Some patients inhale antibiotics such as tobramycin to reduce bacterial load in the lungs. Certain oral antibiotics, like azithromycin, may also reduce flare-ups because of their anti-inflammatory effects.

One of the most promising developments in the field is the drug brensocatib (Brinsupri). This new oral therapy is designed to block an enzyme called neutrophil elastase, which drives much of the destructive inflammation in bronchiectasis. Clinical trials have shown that it may significantly reduce the number of exacerbations and help preserve lung function. This is now FDA approved and is an exciting step forward that offers hope for patients with frequent flare-ups despite standard therapy.

It is also essential to treat any coexisting conditions that worsen bronchiectasis. Patients with NTM infections often require long-term, multi-drug antibiotic regimens tailored to the specific type of bacteria. Those with ABPA may need steroids to reduce inflammation, along with antifungal medications.

Living with Bronchiectasis

Good overall lung health is another critical part of management. Vaccines such as influenza, pneumococcal, and COVID-19 are highly recommended. Smoking cessation is crucial, and pulmonary rehabilitation programs can help improve stamina and breathing efficiency.

Although bronchiectasis is a chronic condition, many people live active and fulfilling lives when they follow a structured care plan. Daily airway clearance, prompt recognition of infections, and regular follow-up with a pulmonary team are all important. With new therapies like brensocatib, treatment is expanding beyond symptom control and beginning to address the underlying drivers of inflammation.

Key Takeaway

Bronchiectasis is a condition where damaged airways trap mucus and lead to repeated infections, but it is manageable. With daily airway clearance, antibiotics, and new targeted therapies, many patients can breathe easier and live fuller lives.

Why Won’t This Cough Go Away?

We’ve all had a cough that lingers after a cold or flu, but what if it just doesn’t stop?

We call it a chronic cough when it lasts longer than eight weeks, and while it may feel like just an annoyance, it can point to something happening underneath the surface. Let’s talk through the most common reasons for a long-lasting cough, what treatments look like, and even some new therapies that are on the horizon.

The Usual Suspects

One of the top culprits is postnasal drip, sometimes called upper airway cough syndrome. This happens when mucus from your nose or sinuses slides down the back of your throat. That constant “drip” tickles your airway and triggers coughing.

Another big one is acid reflux. You may think of reflux as heartburn, but stomach acid can also reach the throat and voice box. When that happens—known as LPR—it irritates the airway, leaving you with a stubborn cough, hoarseness, or the need to constantly clear your throat.

Allergies can also keep a cough going. Pollen, dust, pet dander—your body reacts to these by inflaming the airways, and your cough reflex never takes a break.
Finally, there’s cough-variant asthma. Unlike the classic wheezing form of asthma, this one shows up almost entirely as a nagging cough. It can be tricky to catch without special breathing tests.

Other Reasons Your Cough Might Linger

Sometimes a cough hangs around after a bad infection. We call this a post-infectious cough, and it can stick around for weeks even after you’ve otherwise recovered.
There’s also what’s known as a neurogenic cough, where the nerves in your throat become overly sensitive. In this case, even little things like talking, laughing, or breathing cool air can trigger coughing.

Chronic infections, such as mycobacteria in the lungs, can also be a source of ongoing cough. And for people with swallowing difficulties, aspiration—when food, liquid, or stomach contents slip into the airway—can cause frequent coughing too.

How We Treat It

The first step is always figuring out the cause. We may ask about your symptoms, check your nose and throat, order breathing tests, or even get imaging. From there, treatment can be targeted:

  • Postnasal drip often responds to antihistamines or nasal sprays.
  • Reflux may improve with diet changes and acid-reducing medicines.
  • Allergies can be treated with medications or allergy shots.
  • Asthma-related cough is usually managed with inhalers.
  • Other causes might call for antibiotics, swallowing therapy, or medicines that calm the nerves involved in coughing.

New Treatments on the Horizon

For people who’ve tried everything but still cough, there’s good news. Researchers are studying new therapies that focus on calming the nerves that drive coughing. A class of medicines called P2X3 receptor antagonists has shown promise in clinical trials, and several are close to becoming available. Other approaches, like low-dose neuromodulator medicines or targeted biologic therapies, are also being tested.

The Bottom Line

A cough that won’t quit can feel exhausting and even embarrassing, but it’s not something you have to live with. Most cases can be explained by a handful of common conditions and treated effectively. And for those stubborn coughs, new options are on the way.
