Night sweats often occur as a side effect of certain medications, diseases and medical conditions such as bacterial infections, anxiety and sleep disorders, according to Mayo Clinic. Night sweats occur due to an underlying problem, and are different from normal sweating caused by using numerous blankets or sleeping in an environment with hot temperatures.
Night sweats refer to unusual, excessive sweating during the night that causes a person’s clothes or bedding to get wet, explains Mayo Clinic. Medications than can cause the conditon are antidepressants, hormone therapy drugs and hypoglycemic agents, which are medications that decrease blood sugar levels. Anxiety, autonomic neuropathy and a bacterial infection called brucellosis are other medical conditions that lead to night sweats.
Doctors study an individual’s medical history and perform tests to determine if the night sweats are caused by a medical condition, notes WebMD. Menopausal women often experience night sweats due to hot flashes. People with idiopathic hyperhidrosis sweat excessively without a known medical reason. Tuberculosis is the most common type of infection that causes night sweats. Heart valve inflammation, bone inflammation and abscesses are bacterial infections that also lead to night sweats.
Aspirin, acetaminophen and other drugs that reduce fever sometimes cause night sweats, says WebMD. Sweating also occurs due to low blood sugar. Diabetics who are taking insulin or oral diabetes medicines tend to have low blood sugar, and thus experience sweating. Night sweats are also associated with hormone disorders and cancers.
