What causes recurrent pneumonia?

The main causes of recurrent pneumonia include immune system problems, structural lung diseases, airway diseases, etc. In addition, aspiration pneumonia, iatrogenic factors, genetic factors, etc. may also lead to the occurrence of recurrent pneumonia. Recurrent pneumonia refers to a period of time 3 or more episodes of pneumonia (usually 1 year). The main causes are as follows: 1. Immune system problems: A weak or abnormal immune system may lead to recurrent pneumonia. For example, primary immunodeficiency disease, acquired immunodeficiency syndrome (AIDS), long-term use of immunosuppressants, etc., may make patients susceptible to pneumonia. 2. Structural lung diseases: Some structural lung diseases, such as bronchiectasis, cystic fibrosis, pulmonary fibrosis, etc., affect the normal structure and function of the lungs, leading to lung infection and inflammation. 3. Airway diseases: Airway diseases such as chronic obstructive pulmonary disease (COPD), bronchial asthma, etc., can lead to airway stenosis and secretion retention, increasing susceptibility to pneumonia. 4. Other factors: Aspiration pneumonia: swallowing dysfunction, consciousness disorders and other reasons lead to food or secretions inhaled into the lungs, can cause repeated pneumonia. Iatrogenic factors: long-term hospitalization, use of ventilators, receiving chemotherapy and other medical procedures, may increase the risk of pneumonia. Genetic factors: Certain genetic mutations or genetic disorders may lead to abnormal lung development or immune system problems, increasing the risk of recurrent pneumonia. It should be noted that recurrent pneumonia may be the result of a combination of factors. For patients with recurrent pneumonia, doctors often conduct detailed medical history, physical examination, laboratory tests, and imaging tests to determine the cause and determine treatment options. Treatment options include treatment for the cause, use of immunomodulators, and measures to prevent infection.

In addition, personal hygiene habits, nutritional support, rehabilitation exercise, etc. are also important for disease control and recovery. If you or someone close to you has recurrent pneumonia problems, it is recommended to seek medical attention in time for professional diagnosis and treatment. At the same time, follow the doctor's advice for treatment and management, maintain good living habits and personal hygiene, and help improve the quality of life and prevent recurrence of pneumonia.
