In this episode, Dr. Leonard Zwelling speaks with Dr. Tim Connolly of Houston Methodist Hospital and Texas A&M EnMed School of Medicine about obstructive sleep apnea—a common but often overlooked condition that affects breathing during sleep. They discuss how sleep apnea develops, why it is frequently first noticed by bed partners, and how it can impact overall health if left untreated. The conversation also explores who is most at risk, how new home testing options are making diagnosis easier, and the treatments—from CPAP therapy to nerve-stimulating devices—that can prevent serious complications such as heart disease, stroke, and dementia. This episode highlights why recognizing and treating sleep apnea is critical for long-term health.
