Night sweats

Night sweats refer to episodes of excessive sweating during sleep that can soak clothing and bedding, often occurring without an obvious external cause. Clinically, they are significant as they can indicate underlying conditions such as infections, malignancies, or hormonal imbalances, necessitating further investigation. A key association is with tuberculosis, where night sweats are a classic symptom alongside fever and weight loss, highlighting the need for thorough evaluation in affected patients.
