Often night sweats are caused by an issue that can be easily managed. However, there are some serious illnesses and other diseases that may be the cause as well. One disease that can cause night sweats is tuberculosis.
Tuberculosis is a highly contagious and potentially fatal disease that infects the lungs and can cause severe night sweats. Night sweats are one of the more mild symptoms of tuberculosis and are often brought on by a fever. Other symptoms of tuberculosis include chest pain, difficulty breathing, and coughing up blood.
