At which stage does night sweats occur in pulmonary tuberculosis?

Tuberculosis (TB) is a common disease; its incidence has increased recently due to environmental pollution and deteriorating atmospheric conditions. Patients with weakened immunity are particularly susceptible to TB and require prompt treatment. Coughing often worsens following a diagnosis of pulmonary tuberculosis.

At what stage does night sweats occur in pulmonary tuberculosis?

Night sweats in pulmonary tuberculosis typically occur during the evening or while sleeping. Night sweats are a classic symptom of pulmonary TB, commonly affecting areas such as the neck, forehead, axillae, trunk, back, and inguinal region. With timely and consistent anti-tuberculosis therapy, night sweats usually improve significantly. Pulmonary tuberculosis is a common respiratory disease caused by pathological changes in the body—particularly involving the alveoli and interstitial tissue of the tracheobronchial tree. Some patients continue smoking after being diagnosed with pulmonary TB, which exacerbates coughing. Persistent coughing increases intrapulmonary pressure, predisposing patients to vascular rupture and hemoptysis—posing a serious threat to life and health.

Pulmonary tuberculosis requires symptomatic treatment. Under medical supervision, physical cooling methods or antipyretic-analgesic agents may be appropriately used, especially in cases of hematogenous disseminated pulmonary TB. For patients with cough, antitussive and expectorant therapy is recommended. When minor hemoptysis occurs, small doses of sedatives and antitussives may be administered under professional guidance. However, antitussive medications should be used cautiously in elderly, frail patients or those with compromised pulmonary function.

In daily life, patients should maintain regular, balanced dietary habits—avoiding spicy, irritating foods and refraining from overeating or staying up late. We hope this information is helpful to you.
