About 15 miles west of ORD on arrival we were exposed to a laser beam from the left front of the aircraft.  I was Pilot Monitoring; my First Officer (FO) was flying; and I reported the location to ATC.  About 5 minutes later I experienced an intense nauseous feeling.  I thought I was going to be sick.  The intense nauseous lasted maybe 5 minutes and then I started feeling somewhat better. My FO [advised ATC]; we landed and taxied in without incident.  Medical personnel met our flight and checked my vitals; all being normal.  The upset stomach was still present but not as bad as it was in the air.  Side note...The flight was X hours and 10 minutes; about 90 minutes into the flight we ate a crew meal.  I'm not sure whether the nauseous feeling could be food related or if it was because of the laser.
Experience a laser event followed by a pilot incapacitation followed by an inflight [urgency situation] on approach into ORD. Arrived at the gate and was evaluated by EMS. Had to wait an hour for crew transportation to the hotel. Arrived at the hotel after midnight. Stayed up to record the details of the flight. Called [operations] around XA:00 to say I was not rested physically or emotionally to operate the flight tonight that had a hotel pickup time of XB:00 followed by a X hour flight.
Air Carrier Pilot Crew encountered a laser while on final approach; reported that the Captain became ill after the event. First Officer completed a normal landing.
