Bell's palsy occurs more often in people who:

  • Are pregnant, especially during the third trimester, or who are in the first week after giving birth
  • Have an upper respiratory infection, such as the flu or a cold

Also, some people who have recurrent attacks of Bell's palsy, which is rare, have a family history of recurrent attacks. In those cases, there may be a genetic predisposition to Bell's palsy.
