Sweating during the course of tuberculosis treatment is usually due to incomplete cure of tuberculosis, and patients can continue to follow the doctor’s instructions for treatment. Tuberculosis is one of the more common infectious diseases of the respiratory system, and night sweats are a typical clinical symptom of the disease, often leading to unexplained sweating. Sweating in the course of treatment is usually due to night sweats, suggesting that the patient’s condition has not yet been cured. Patients who sweat during treatment should continue to be treated with isoniazid, rifampicin, ethambutol, pyrazinamide and other chemotherapy regimens as prescribed by the doctor, and should be followed up regularly to adjust the treatment regimen according to their actual condition. Meanwhile, for patients with poor chemotherapy effect or serious condition, such as tuberculous pyothorax, surgery such as lobectomy may be needed. To summarize, sweating during tuberculosis treatment is a normal phenomenon, and patients do not need to be overly nervous. After active and standardized treatment, the condition of most patients will start to improve in 2~3 weeks and gradually be cured, after which the patients will no longer have sweating symptoms.
