Idiopathic Pulmonary Fibrosis (IPF) is a chronic lung disease characterized by the progressive scarring of lung tissue, which makes it difficult for the lungs to function properly. The term "idiopathic" means that the exact cause of the disease is unknown. Symptoms often include shortness of breath, a persistent dry cough, and fatigue, which can significantly impact daily life. As the disease progresses, the lung tissue becomes increasingly stiff, leading to reduced oxygen levels in the bloodstream. Diagnosis typically involves imaging tests like CT scans and lung function tests. While there is no cure for IPF, treatments are available to help manage symptoms and slow disease progression.
