A cough that doesn’t go away. Fatigue that makes everyday activities more difficult. Shortness of breath that seems to be getting worse.
These symptoms can have many causes, but they can also occur with nontuberculous mycobacterial (NTM) lung disease. Because NTM symptoms may overlap with those of other respiratory conditions, recognizing changes in your health and discussing persistent symptoms with a healthcare provider can be an important step toward getting answers.
Understanding what to look for can help patients become better informed and better prepared for conversations with their healthcare team.
What Is NTM Lung Disease?
Nontuberculous mycobacteria, or NTM, are bacteria found naturally in the environment, including in water and soil. There are many species of NTM, and most people who encounter these bacteria do not become ill.
However; in some people, NTM can cause an infection in the lungs. People with underlying lung conditions, including bronchiectasis, may be at increased risk.
NTM lung disease can develop gradually, which is one reason recognizing it can be challenging.
What Are the Symptoms of NTM Lung Disease?
NTM lung disease doesn’t look exactly the same for everyone. Symptoms can vary in type and severity and may develop slowly over time.
Commonly reported symptoms can include:
- Persistent or recurring cough
- Coughing up mucus or sputum
- Fatigue or low energy
- Shortness of breath
- Unexplained weight loss or loss of appetite
- Fever or low-grade fever
- Night sweats
- Coughing up blood
Having one or more of these symptoms does not necessarily mean that you have NTM lung disease. Many respiratory illnesses can cause similar symptoms, which is why a proper medical evaluation is important.
Why Can NTM Lung Disease Be Difficult to Recognize?
One of the challenges with NTM lung disease is that its symptoms can resemble those of other respiratory conditions.
A chronic cough, for example, may have many possible causes. Fatigue and shortness of breath are also common across numerous health conditions. For someone already living with bronchiectasis or another chronic lung disease, changes may initially seem like part of an existing condition.
NTM lung disease also may progress slowly. When symptoms develop gradually, it can be difficult to recognize how much has changed.
Keeping track of your symptoms and communicating those changes to your healthcare provider can help provide a clearer picture over time.
NTM Lung Disease and Bronchiectasis
NTM lung disease and bronchiectasis are closely associated, although they are different conditions.
Bronchiectasis causes the airways to become abnormally widened and damaged, which can make it more difficult to clear mucus. This can create an environment in which respiratory infections may occur.
Some people with bronchiectasis develop NTM lung disease, while some people diagnosed with NTM are subsequently found to have underlying bronchiectasis.
If you live with bronchiectasis, understanding your usual symptoms can make it easier to recognize meaningful changes and discuss them with your healthcare team.
When Should You Talk to Your Doctor?
You don’t need to determine on your own whether your symptoms are caused by NTM.
Consider talking with a healthcare provider if you have respiratory symptoms that persist, recur, become more severe, or are different from what’s normal for you.
If you already have a chronic lung condition, tell your healthcare provider about changes such as increased coughing or mucus, worsening fatigue or breathlessness, changes in appetite or weight, or other new or concerning symptoms.
Seek urgent medical care for severe difficulty breathing, significant coughing up of blood, or other symptoms that may represent a medical emergency.
How Is NTM Lung Disease Diagnosed?
Symptoms alone cannot confirm NTM lung disease.
Diagnosis generally requires healthcare professionals to consider several pieces of information together. Depending on the individual, evaluation may include a review of symptoms and medical history, chest imaging, and laboratory testing of respiratory samples such as sputum.
Because NTM organisms can sometimes be present without causing progressive disease, identifying NTM in a sample does not automatically mean that treatment is necessary. Your healthcare team will consider your overall clinical picture when determining next steps.
Prepare for Your Healthcare Appointment
Being prepared can help you make the most of your appointment.
Consider keeping notes about:
- When your symptoms began
- Whether they have changed over time
- How often you cough
- Changes in mucus or sputum
- Changes in your energy level or breathing
- Changes in appetite or weight
- Respiratory infections you’ve experienced
- Medications and treatments you’re currently using
You can also write down questions before your visit so you don’t have to rely on memory during the appointment.
Knowledge Can Help You Advocate for Your Health
Living with unexplained respiratory symptoms can be frustrating, particularly when answers don’t come quickly.
Learning about NTM lung disease doesn’t mean trying to diagnose yourself. It means becoming an informed participant in your healthcare.
If something doesn’t feel right, keep the conversation going with your healthcare team. Ask questions. Keep track of changes. And if NTM lung disease is suspected or diagnosed, seek reliable information to help you understand what comes next.
