Lung fibrosis, also known as pulmonary fibrosis, is a condition characterized by the scarring and thickening of lung tissue. This can lead to difficulty breathing, coughing, and reduced lung function. The cause of lung fibrosis is often unknown, but it can be associated with certain environmental exposures, autoimmune diseases, and genetic factors. Research in the field of lung fibrosis focuses on understanding the underlying mechanisms of the disease, developing effective treatments to slow its progression, and ultimately finding a cure. This research often involves studying the role of inflammation, immune response, and fibrotic pathways in the development of lung fibrosis. Current treatment options for lung fibrosis include medications to reduce inflammation and scarring, oxygen therapy, and lung transplant in severe cases. Ongoing research aims to improve these treatments and discover new approaches to better manage and potentially reverse lung fibrosis.
