Persons with diabetes have a 29% higher risk of being affected by Bell palsy than do persons without diabetes. Thus, measuring blood glucose levels at the time of diagnosis of Bell palsy may detect undiagnosed diabetes. Diabetic patients are 30% more likely than nondiabetic patients to have only partial recovery; recurrence of Bell palsy is also more common among diabetic patients. [32]

Bell palsy is also more common in people who are immunocompromised or in women with preeclampsia. [33]
