Bronchiolitis Obliterans Syndrome

BOS is a lung problem that can occur after lung transplantation and is the most common form of chronic lung transplant rejection. More than half of lung transplant recipients develop BOS within five years of transplantation. When BOS develops, a person will have a progressive loss of lung function when compared to the highest function after transplantation.

The Lung Transplant Foundation is a 501(c)3 non-profit organization.
