<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, Ive noticed that Ive been experiencing fluid retention, hot flashes, and mouth dryness lately. What could be causing these symptoms?  <response>: Based on your symptoms, its possible that you have aplastic anemia. This is a rare condition in which your body doesnt produce enough new blood cells, causing such symptoms. I advise you to come in for a proper checkup and diagnosis.
