👉 Hansen's disease, also known as idiopathic pulmonary fibrosis or idiopathic pulmonary hypertension, is a chronic lung disease characterized by progressive airway narrowing and obstruction due to inflammation of the airways, which leads to the development of multiple airways.

This condition typically affects people who are genetically predisposed to the disease or have a family history of it
