Primary Ciliary Dyskinesia (PCD) is a rare genetic disorder that affects the tiny hair-like structures called cilia found on the surface of cells. These cilia help move mucus and other substances out of the lungs and other organs. In people with PCD, the cilia do not function properly, leading to problems like chronic respiratory infections, sinus issues, and fertility challenges. Because the cilia are essential for clearing mucus, individuals with PCD often experience persistent coughs and difficulty breathing. Early diagnosis and treatment are crucial to manage symptoms and improve quality of life. Regular check-ups with healthcare providers can help monitor and address complications associated with this condition.
