Does tuberculosis cause night sweats?

Tuberculosis is an infection that can affect the lungs or other parts of the body. Night sweats may happen as the immune system responds to infection, and they can be especially noticeable when sleepwear or bedding becomes damp. Other explanations include a warm bedroom, medicines, hormonal changes, anxiety, or other infections. Tuberculosis may also cause a cough that persists, fever, tiredness, reduced appetite, or weight loss. The pattern of symptoms and your exposure history matter more than one symptom.

Arrange a clinical assessment if night sweats keep returning, soak your clothes or bedding, or occur with a persistent cough, fever, reduced appetite, or unusual tiredness. A clinician may ask about close contact with tuberculosis, previous illness, travel, and immune health. Assessment can include an examination, a chest image, and tuberculosis tests chosen for your situation. Do not start or stop tuberculosis medicine without medical guidance, because treatment requires a planned combination and follow-up.

Seek urgent help for severe breathing difficulty, chest pain, confusion, fainting, coughing blood, or marked weakness. Contact a clinician promptly if you have ongoing night sweats with fever or cough, or if you have had close contact with someone who has infectious tuberculosis. Until assessed, follow local medical advice about masking and close indoor contact if tuberculosis is suspected.

Ask whether your symptoms fit tuberculosis or another cause, which test is appropriate, whether you need a chest image, and how to reduce possible spread while waiting for results.
