What are the causes of enlarged pulmonary and mediastinal lymph nodes?

In general, mediastinal lymphadenopathy may be caused by conditions such as pneumonia, lymph node tuberculosis, chronic lymphadenitis, pulmonary tuberculosis, or systemic lupus erythematosus. It is recommended to seek medical attention promptly to determine the underlying cause and receive appropriate treatment. Specific analyses are as follows:

1. Pneumonia

This is usually caused by bacterial infection, which may damage lung tissue and lead to symptoms including mediastinal lymphadenopathy, fever, and cough. Under medical guidance, medications such as ambroxol hydrochloride oral solution, thymopeptin enteric-coated tablets, and ibuprofen granules may be used for treatment.

2. Lymph Node Tuberculosis

This is generally caused by Mycobacterium tuberculosis infection, which may lead to enlarged lymph nodes and result in the aforementioned symptoms, possibly accompanied by chest pain and difficulty breathing. Under medical supervision, medications such as rifampicin capsules, pyrazinamide tablets, and isoniazid tablets may be used for treatment.

3. Chronic Lymphadenitis

This may be caused by prolonged stimulation of lymph nodes due to bacteria, viruses, or other pathogens, easily affecting mediastinal lymph nodes and causing enlargement. It is often accompanied by discomfort such as fever and pain. As directed by a physician, medications such as amoxicillin capsules, amoxicillin and dicloxacillin sodium capsules, and cefixime tablets may be used for treatment.

4. Pulmonary Tuberculosis

This is usually caused by Mycobacterium tuberculosis infection. The inflammation may spread to mediastinal lymph nodes, leading to enlargement, along with symptoms such as sputum production, low-grade fever, night sweats, and fatigue. It is recommended to use medications such as Shenling Baizhu Powder, Hecheda Zao Pills, and Baihe Gujin Pills under medical guidance.

5. Systemic Lupus Erythematosus

This is generally caused by genetic factors and may lead the immune system to attack mediastinal lymph nodes, resulting in the above-mentioned condition, along with symptoms such as rashes and joint pain. Medications such as hydroxychloroquine sulfate tablets, azathioprine tablets, and prednisone acetate tablets may be used under medical supervision.

Maintaining healthy lifestyle habits is important in daily life—going to bed early and waking up early, trying to sleep before 11 p.m. each night, avoiding staying up late, and ensuring sufficient sleep—all of which contribute to overall health.
