Overview

Idiopathic pulmonary fibrosis, often called IPF, is a serious lung disease where the tissue deep inside the lungs becomes scarred and stiff over time. The word 'idiopathic' means doctors do not know the exact cause. As the scarring (called fibrosis) builds up, the lungs lose their ability to stretch and move air in and out properly. This makes it harder and harder for oxygen to pass from the lungs into the bloodstream. IPF is sometimes also referred to as cryptogenic fibrosing alveolitis, especially in older medical records from the United Kingdom. The most common symptoms are a dry, persistent cough and shortness of breath, especially during physical activity. Over time, even simple tasks like walking across a room or climbing stairs can feel exhausting. Some people notice their fingertips or toes become rounded and wider, a sign called 'clubbing.' Fatigue and unintentional weight loss are also common as the disease progresses. There is no cure for IPF, but two medications — nintedanib (Ofev) and pirfenidone (Esbriet) — are approved by the FDA and have been shown to slow the scarring process. Oxygen therapy, pulmonary rehabilitation, and in some cases lung transplantation are also important parts of care. Early diagnosis and treatment give patients the best chance of maintaining quality of life for as long as possible.
