Yes, Medicine comeds under Emergency Services like Police, Fire etc which needs to operate 24*7. So, not only Doctors but all staffs have night shift as well as morning shift. For a extra info, a doctor during his residency works 18 hrs a day and sometimes 48 hrs at a stretch !
Only passion and love for medicine can drive such force . Hence while choosing Medicine as profession one must be fully affectionate towards it !
Good Luck !
