IPF is the acronym and abbreviation for idiopathic interstitial pulmonary fibrosis, a clinically serious disease that is a change in end-stage lung disease, which manifests mainly as chronic progressive interstitial fibrosis. The specific cause of the disease is unknown and is therefore called idiopathic interstitial fibrosis. The clinical symptoms of the disease are mainly dyspnea after activity, with progressive exacerbation, dry cough and generalized weakness and weight loss. On chest radiographs or lung CT, the disease may appear as a diffuse reticular or lattice-like blurring of both lungs and may appear as a honeycomb pattern. The diagnosis of the disease requires a lung biopsy to obtain a pathological diagnosis, and lung transplantation is required for poor results of medical treatment, with an average survival time of about 3 years.
