Hi I Am A 23 Year Old Male. For The

Hi I am a 23 year old male. For the past week in a half I have been experiencing symptoms of less appetite than usual (my wife keeps commenting), I'm quite thirsty, I have a bit less energy than unusual. In the morning I wake up sweating profusely (soaked through). I am wondering if this is concerning?
(I had fever right before this which dr said is viral began and so I at first thought perhaps it was just viralike symptoms continuing?)
