A new animal study suggests that obstructive sleep apnea (OSA) may worsen idiopathic pulmonary fibrosis (IPF), a serious disease that causes progressive lung scarring. Researchers found that intermittent drops in oxygen levels—similar to those experienced during sleep apnea—intensified lung damage, collagen buildup, and fibrosis, especially when oxygen deprivation occurred before lung injury. These findings indicate that sleep apnea may accelerate the progression of IPF rather than simply coexist with it. The study also highlights the importance of early diagnosis and treatment of sleep apnea, which could help slow lung scarring and improve long-term outcomes for people living with IPF.
