Just after door closed; Passenger X came back and asked to use the restroom.  He said that he was about to start coughing.  Once inside the lav; we (myself and other passengers) could hear him coughing so hard that he was gagging.  2 passengers expressed concern.  When he came out; I asked if he was feeling alright.  He told me that it was just allergies and he didn't want to start coughing in front of everyone.  Twice; during taxi; I had to ask him to put his mask back on. (Note: if someone is eating or drinking; I leave them alone.  But he was reading and/or digging through his bags.)  In flight; as soon as I went upfront; we went into the lav again after 2 more lav visits; I went back and asked him again if he was alright.  He told me that he 'Wasn't feeling well;' but that it was because he hadn't eaten breakfast. We provided everyone with snack bags and I kept an eye on him.  After several more lav trips; I called the PIC and informed him of what was going on.  The PIC asked us if we had a way of taking his temp. We said no and suggested he call for a [customer service agent] to meet the flight.  Throughout the flight; Passenger X came back to use the restroom a total of 5 times and had to be told 3 times to; please; put his mask back on.  Just after we had taken our seats for landing; he came back for a 6th time and asked me to move so that he could use the restroom.  I told him that we were about to land and that he needed to return to his seat.  He wasn't happy; but complied.  After arriving at the gate; he came back to use the lav again.  The PIC called and asked if we (the FAs) would ask him to stay seated until everyone else had deplaned so someone to talk with him.  I asked him and he was very unhappy and agreed while yanking off his mask. I must have looked surprised because; after looking back at my face; he quickly put his mask back on.  He deplaned last and a [customer service agent] was there to meet him.  The other FA informed me that; when he first boarded the plane; he had immediately used the forward restroom.  That totaled 9 trips to the lav in 1.5-2 hrs and many requests to keep his mask on.
Flight Attendant reported a passenger using the restroom numerous times; coughing and having to constantly be reminded to wear a mask.
