Brief Answer: Clinical examination and investigations will help. Detailed Answer: Hi, Thanks for writing your query. It will be helpful if you give more information about any medicine you are taking or any history of recent illness. After reading your post, I would like to advise that you should get yourself clinically examined and investigated. Night sweats can occur due to different causes.If you are not using excessive bed clothing and the room temperature is not very hot, you can consider following investigations to be helpful :- 1. Blood sugar levels. 2. Complete Blood Count(CBC). 3. ELISA test for tuberculosis. 4. Thyroid profile. 5. Urine examination. Also record your temperature regularly, especially at nights. If night sweats are not due to any underlying medical condition, they are harmless. I hope this is helpful to you. Thanks.
