What are the causes of interstitial pneumonia? Urgent! Urgent!

Interstitial pneumonia is one of the lung diseases, and there are many causes of interstitial pneumonia, and the following is a summary of the eight common ones.

**1. Chronic diseases of rheumatism and immunity: systemic sclerosis, polymyositis, dermatomyositis, systemic lupus erythematosus, rheumatoid arthritis, mixed connective tissue disease, ankylosing spondylitis.

4. Inhalation of inorganic dust: talc, iron pneumoconiosis, tin pneumoconiosis.

**5. Inhalation of organic particles (allergic alveolitis): pigeon breeder's lungs, farmers' lungs.

**6. Surgery for primary diseases (not classified into types), neoplastic diseases: pulmonary lyocneduct carcinoma, bronchoalveolar carcinoma, pulmonary lymphoma, Kaposi sarcoma.

**7. Idiopathic fibrosis diseases are prominent: physical-onset fibrosis, familial idiopathic pulmonary interstitial fibrosis, acute interstitial pneumonia, desquamative interstitial pneumonia, non-specific interstitial pneumonia, lymphocytic interstitial pneumonia, autoimmune pulmonary interstitial fibrosis.

8. Others: neurofibromatosis, tuberous sclerosis, sarcoidosis, eosinophilic pneumonia, pulmonary alveolar protein precipitation, diffuse alveolar hemorrhage, alveolar microstone disease, metastatic calcification.

Interstitial pneumonia** includes infectious factors, environmental factors, drug or**related factors, connective tissue diseases, and other factors;

Interstitial pneumonia refers to a group of interstitial lung diseases with inflammation and pulmonary fibrosis.

1.Infectious factors: Can be caused by mycoplasma, chlamydia, bacteria, viruses, or Pneumocystis.

2.Environmental factors: long-term exposure to undesirable environments such as dust, such as metal dust such as brass and lead, or organic dust such as animal hair and feathers.

4.Connective tissue diseases: patients with systemic scleroderma, rheumatoid arthritis, Sjögren's syndrome, etc.

5.Others: Smoking, genetics, etc. can increase the risk of developing the disease.

If you feel unwell, go to the hospital as soon as possible to clarify**, and formulate an individualized diagnosis and treatment plan according to the specific condition.

Interstitial pneumonia is an interstitial inflammatory and fibrotic disease of the lungs caused by a variety of causes, and the lesions are mainly in the bronchi, bronchioles and perivascular areas, as well as in the connective tissues of the interlobular septum, with lymphocyte and monocyte infiltration as histological features. The clinical manifestations of interstitial pneumonia are nonspecific, and early signs are often milder than symptomatic, often presenting with fever, dry cough, sputum production, chest pain, and progressive dyspnea.
