Nontuberculous Mycobacteria (NTM) Lung Disease in Grand Rapids, MI

Nontuberculous mycobacteria (NTM) lung disease is a serious, long-term lung infection caused by environmental bacteria commonly found in dust, soil, and water. While these bacteria are not the same as tuberculosis, they can still cause significant lung damage and illness, especially in people with underlying lung problems.

In the Grand Rapids and West Michigan region, where residents experience humid summers, cold winters, and frequent indoor heating, understanding NTM lung disease is important for protecting long-term lung health.

Who Is at Risk for NTM Lung Disease?

NTM lung disease can affect anyone, but it is more commonly seen in:

  • Women over 50 years old
  • People of European or Asian descent
  • Individuals with chronic lung conditions such as:
    • Bronchiectasis
    • COPD or emphysema
    • Asthma
    • Cystic fibrosis
  • People with weakened immune systems

Although NTM lung disease is more often reported in warmer climates, it is increasingly recognized in northern states like Michigan, including the Grand Rapids area. Indoor hot water systems, humidifiers, and poorly maintained hot tubs can be potential sources of exposure, even in colder regions.

Signs and Symptoms of NTM Lung Disease

NTM lung disease usually develops slowly. Symptoms can be mild at first and are often mistaken for other lung conditions, such as chronic bronchitis or recurrent pneumonia.

Common signs and symptoms include:

  • Persistent cough (often lasting months)
  • Coughing up mucus or sputum
  • Occasional blood in sputum
  • Chest pain or discomfort
  • Shortness of breath, especially with activity
  • Unexplained weight loss
  • Loss of appetite
  • Night sweats
  • Low-grade fever
  • Fatigue and lack of energy

If you live in the Grand Rapids area and have ongoing respiratory symptoms that are not improving with usual treatment, talk with your primary care provider or a pulmonary specialist at Spectrum Health, Trinity Health Grand Rapids, Metro Health, or Mercy Health.

How NTM Lung Disease Is Diagnosed in Grand Rapids

NTM lung disease can be difficult to diagnose and is sometimes missed or mistaken for other lung conditions. A thorough evaluation by a lung specialist (pulmonologist) is important.

Diagnosis typically includes:

1. Detailed Medical History and Physical Exam

Your provider will ask about:

  • Length and type of symptoms
  • Past lung infections or conditions
  • Smoking history
  • Home environment (well water, hot tubs, humidifiers)
  • Hobbies (such as gardening or working with potting soil)

2. Imaging Tests

  • Chest CT scan: This is the key imaging test for NTM lung disease. It shows detailed views of the lungs and can reveal:
    • Bronchiectasis (damaged, widened airways)
    • Nodules or cavities
    • Areas of inflammation or infection

Standard chest X-rays usually do not provide enough detail to diagnose NTM lung disease accurately.

3. Sputum Tests

  • Sputum culture: Samples of mucus that you cough up are tested in a lab for NTM bacteria.
  • Acid-fast bacilli (AFB) smear and culture: This specialized test looks for mycobacteria, including NTM.
  • Sometimes, a bronchoscopy (a procedure using a thin camera inside the airways) is needed to collect samples.

In Grand Rapids, these tests are typically available through major health systems such as Spectrum Health and Trinity Health Grand Rapids, and can be coordinated by a pulmonologist.

Do All Patients Need Treatment?

Not everyone diagnosed with NTM lung disease needs immediate treatment. Some people have mild disease that can be closely monitored before starting antibiotics.

Your pulmonologist will consider:

  • Severity of symptoms
  • CT scan findings
  • Type of NTM bacteria identified
  • Overall health and other medical conditions

Because treatment is complex and long-term, it is important to be evaluated by a specialist experienced in managing NTM lung disease. In Grand Rapids, ask for referral to a pulmonary clinic familiar with bronchiectasis and NTM infections.

Treatment of NTM Lung Disease

Long-Term Antibiotic Therapy

Treatment usually involves:

  • A combination of antibiotics taken together
  • Therapy often lasting 18 to 24 months or longer
  • Regular follow-up visits and lab work to monitor side effects and response

Antibiotic regimens are tailored to the specific NTM species and your overall health. Side effects can include stomach upset, changes in vision or hearing, and liver issues, so close monitoring is essential.

Airway Clearance and Pulmonary Care

Clearing mucus from the lungs is a critical part of treatment. This may include:

  • Airway clearance physiotherapy
    • Breathing exercises
    • Huff coughing techniques
    • Use of devices such as flutter valves or positive expiratory pressure (PEP) devices
  • Inhaled medications, if prescribed, to open airways and thin mucus

Ask your provider for a referral to a respiratory therapist or physiotherapist experienced in airway clearance techniques. Larger health systems in Grand Rapids typically offer these services through their pulmonary rehabilitation or outpatient therapy programs.

Preventing NTM Exposure in Grand Rapids, MI

While NTM bacteria are common in the environment and cannot be completely avoided, you can reduce your risk of exposure and infection.

At Home: Water and Plumbing

  • Ensure your hot water system is installed and maintained correctly.
  • Keep hot water at the recommended temperature (typically above 60°C / 140°F) to reduce bacterial growth.
  • Have your taps, showers, and spa baths installed and serviced by qualified professionals.
  • Regularly clean and maintain:
    • Showerheads
    • Humidifiers
    • CPAP or BiPAP equipment (using distilled water and manufacturer-recommended cleaning routines)

Hot Tubs and Spas

  • Poorly maintained hot tubs can harbor NTM.
  • Make sure any spa, hot tub, or whirlpool you use is:
    • Properly chlorinated or treated
    • Regularly cleaned and serviced
  • If you have chronic lung disease, talk with your doctor about whether hot tub use is safe for you.

Gardening and Outdoor Activities in Michigan

Gardening is a common hobby in West Michigan, but soil and potting mix can contain NTM:

  • When working with soil, mulch, or potting mix:
    • Wear a well-fitting dust mask or respirator
    • Work in well-ventilated outdoor areas
    • Avoid shaking dry potting mix close to your face
  • Wash your hands and change clothes after gardening.

These steps are especially important during Michigan’s spring and summer months, when outdoor yard work increases.

Living with NTM Lung Disease in Grand Rapids

Managing NTM lung disease is a long-term process that affects both physical and emotional health.

Daily Self-Care

  • Get enough rest and pace your activities.
  • Eat a balanced, nutritious diet to support your immune system and maintain a healthy weight.
  • Stay active as tolerated; ask about pulmonary rehabilitation programs offered through:
    • Spectrum Health
    • Trinity Health Grand Rapids
