Interstitial Lung Disease (ILD) refers to a group of disorders that cause inflammation and scarring of the lung tissue. This damage affects the lungs' ability to transfer oxygen into the bloodstream, leading to symptoms such as shortness of breath and a persistent cough. ILD can result from various factors, including exposure to environmental pollutants, certain medications, and autoimmune diseases like rheumatoid arthritis. Diagnosis of ILD typically involves imaging tests like chest X-rays or CT scans, along with lung function tests. Treatment options may include medications to reduce inflammation, oxygen therapy, and in severe cases, lung transplantation. Early detection and management are crucial for improving quality of life.
