This disease comes under the broad heading called ” Diffuse Pulmonary ILD” (DPILD), meaning affecting many parts of lung. It is a disease of interstitial tissue in the lung ( between air sacs and broncheal tubes) causing progressive breathlessness over the years with dry cough. If not detected early, it will lead to a chronic interstitial scarring, thickening and holes in the lung (called ‘honey combing’) that is irreversible. There are several causes for this disease. It includes a variety of Connective tissue disorder, Sarcoidosis, Chronic Hypersensitivity pneumonitis and Idiopathic Pulmonary Fibrosis (IPF).
IPF, usually affect elderly people which is progressive and fatal with no definitive cure so for. IPF can be diagnosed solely based on HRCT(High Resolution CT scan) of the chest alone. ILD patients if not diagnosed early will end up using continuous oxygen and may require lung transplantation.
