10. Bacterial Infection
Certain infections may cause you to wake up in a sweat during the nighttime. Tuberculosis (TB) is one such infection. Tuberculosis is caused by a bacterial infection that is spread through the air. The TB bacteria grow in the lungs and cause symptoms such as chest pain, an aggravating cough lasting more than three weeks, and the coughing up of blood and mucus. Other symptoms may include weight loss, fever, chills, and night sweats. Bacterial endocarditis is a bacterial infection that affects the heart valves or the lining of the heart. In addition to night sweats, symptoms may include chest pain, shortness of breath, and swollen ankles.
9. Certain Cancers
The American Cancer Society lists “drenching night sweats” as one symptom of non-Hodgkin lymphoma. Non-Hodgkin lymphoma is a cancer that begins in the white blood cells of the immune system. Other symptoms of non-Hodgkin lymphoma include enlarged lymph nodes, weight loss, chest pain, and frequent infections. Acute lymphocytic leukemia is a cancer of the blood and may also result in night sweats. Other symptoms include weakness, recurring infections, severe bleeding, and bruises on the skin. Check with your doctor if you notice any of these symptoms.
8. Diabetes Mellitus
Diabetes is another autoimmune disorder that may result in night sweats. Other signs and symptoms of either type 1 or type 2 diabetes are increased thirst, frequent urination, unexplained weight loss, and frequent infections. As the body is unable to utilize glucose, it may turn to breaking down muscle and fat to use as energy. This breakdown of muscle and fat can result in excess ketones in the urine. Depending on the type of diabetes, blood sugar levels may respond to dietary and lifestyle changes. In other cases, insulin treatment may be required.Related: 7 Most Common Symptoms of Diabetes
