Bell’s palsy is a sudden and temporary condition that causes weakness or paralysis on one side of the face. It affects people of all ages but is most common between 15 and 45. The exact cause is unknown, but it may be triggered by infections, high blood pressure, diabetes, obesity, pregnancy, or autoimmune disorders. Symptoms include difficulty closing an eyelid, a drooping eye or mouth, or paralysis of an entire half of the face. Diagnosis involves a physical examination, and treatment options may include steroidal medications, antivirals, and eye care. Fortunately, most people recover within a few weeks to six months.
