Symptoms and Signs of Night Sweats in Men and Women

Doctor's Notes on Night Sweats in Men and Women

Night sweats refers to excessive sweating during sleep. Nights sweats are a common symptom of several different medical conditions and can happen in both women and men. Examples of conditions that can cause night sweats include the menopausal transition in women, other hormonal problems such as hyperthyroidism, neurological problems, taking certain medications, and low blood glucose levels. Less common causes include certain infections and cancers such as lymphoma.

True night sweats may be so severe as to drench bed sheets and sleepwear. Other signs and symptoms associated with night sweats depend on the exact cause of the problem. These can include fever, chills, mood changes, hot flashes, vaginal dryness, headache, sleep disturbances, flushing, weight loss, shaking or trembling, anxiety, fatigue, problems with concentration, or weakness.
