Yes, GVHD can definitely affect the lungs and cause respiratory issues. Lung problems occur in up to 70% of people who've had an allogeneic stem cell transplant, and chronic GVHD is a major contributing factor.
The most common lung complication is a condition called bronchiolitis obliterans syndrome (BOS), which affects about 14% of people with chronic GVHD. It causes inflammation and scarring in the small airways, making breathing harder over time. Symptoms to watch out for include:
- A dry cough lasting more than 2–4 weeks
- Shortness of breath, especially during activity
- Chest tightness or difficulty breathing deeply
- Wheezing
It's worth knowing that about 20% of people with BOS have no symptoms at first, so regular monitoring is really important. Some risk factors for developing lung complications include being older at the time of transplant, having a donor tissue-type mismatch, or having had a respiratory infection within the first 100 days after transplant.
If any new or worsening breathing symptoms are noticed, reaching out to a care team right away is strongly recommended. Early treatment can help prevent further damage and protect quality of life.
