Lung scarring is minimized through pulmonary rehabilitation, breathing through a mask, and taking pirfenidone, states NHS Choices. Young patients with lung scarring, but who otherwise have good health, can qualify for a lung transplant. There is no cure for lung scarring, so treatment involves easing the symptoms and reducing progression.
Also known as idiopathic pulmonary fibrosis or pulmonary fibrosis, lung scarring is a rare disease that causes scar tissue to grow in the lungs, according to WebMD. The term "idiopathic" means the condition is unknown or not understood well. This condition slows the circulation of oxygen from the lungs to the blood, leading to poor functioning of the body. Doctors are not sure about the cause of the condition. Smoking, breathing metal or wood dust, or suffering from acid reflux increases the chances of experiencing the condition.
Symptoms of lung scarring include breath shortness, fatigue, persistent dry cough, shallow breathing and aching muscles, notes the American Lung Association. A person may also experience unexplained weight loss and clubbing. As of 2015, the U.S. Food and Drug Administration has approved two medications for treatment for pulmonary fibrosis: nintedanib and pirfenidone. These medications help to prevent the worsening of mild-to-moderate cases of lung scarring.
