When to worry about night sweats with tuberculosis

Tuberculosis is an infection that can affect the lungs and other parts of the body. Night sweating may occur as the immune system responds. A cough lasting several weeks, fever, reduced appetite, tiredness, or weight loss makes assessment more important. Night sweats alone have many possible causes and do not establish tuberculosis.

Contact a clinician promptly if you have ongoing night sweats with cough, fever, chest discomfort, poor appetite, or unusual fatigue. Mention close contact with someone diagnosed with tuberculosis, previous tuberculosis, travel or residence in an area where it is common, and any immune-system condition or treatment. Follow advice about testing and reducing close exposure until assessed.

Seek same-day medical advice for coughing blood, breathing difficulty, chest pain, confusion, severe weakness, or inability to keep fluids down. If tuberculosis is confirmed or suspected, take prescribed treatment exactly as directed and attend follow-up appointments; stopping early can allow illness to return or spread. Emergency services are appropriate for severe breathlessness or heavy bleeding.

Which tests are appropriate for my symptoms and exposure history? Could I pass an infection to household members? When can I safely return to work or close contact, and how should treatment side effects be handled?
