Stress and lack of sleep: two of the possible causes behind facial paralysis
Bell's facial paralysis is a condition that causes sudden weakness in the muscles on one side of the face. Although it is short-term and improves in a few weeks, it causes one half of the face to droop, making smiles lopsided and making it difficult to close the affected eye.
TL;DR
- Bell's facial paralysis causes sudden weakness on one side of the face, leading to a drooping appearance and difficulty closing the affected eye.
- It is believed to be caused by swelling and irritation of the facial nerve, with symptoms improving over weeks and full recovery typically occurring within six months.
- While exact causes are unknown, it's often linked to viral infections such as herpes, chickenpox, flu, and respiratory illnesses.
- Risk factors include pregnancy, obesity, high blood pressure, diabetes, and upper respiratory tract infections, with stress, lack of sleep, and physical trauma also being potential triggers.
- Complications can include irreversible nerve damage, irregular nerve fiber growth, and partial or complete blindness due to excessive dryness.
- Treatments consist of medications like corticosteroids, antivirals, pain relievers, eye drops, and physiotherapy.
