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