The cause of Bell’s palsy isn’t exactly known, but it can be triggered by dental treatment, virus, or injury and inflammation of the nerve that controls the muscles of the face.ĭue to the nerve injury, changes occur in the muscle it controls and the cells in the nerves. Bell’s palsyīell’s palsy is a condition where the muscles suddenly become weak on one side of the face. Some cases of lip twitching can be associated with Parkinson’s disease, but this association is rare. In many people, there is no apparent cause for the twitching of the lips.īotulinum toxin injections have been seen to improve the condition in 95% of patients with HFS. Sometimes, lip twitching is caused by abnormalities in blood vessels, injuries to the nerves, or tumors in the brain. The facial nerve on the same side of the twitching is the culprit. One condition that causes forceful muscle spasms on one side of the face is called hemifacial spasm (HFS). Several neurologic movement disorders can also cause lip twitching. The pregnant mother is passing her calcium to her fetus during pregnancy, and there is an uptick of this transfer in the final trimester. In pregnancy, low calcium is fairly common. The condition is treated with intravenous calcium and oral calcium supplements. Low calcium in the blood, or hypocalcemia, can result in lip twitching. Several other common and uncommon conditions can lead to involuntary twitching of the lips: 1. (1) Other Conditions That May Cause Lip Twitching Having the issue diagnosed and treated can solve the problem.

Sleep apnea is also considered a trigger for lip twitching. (3)Įxposure to corticosteroids, certain medications, and heavy metal pollutants can also cause lip twitching due to fasciculations. Too much potassium can be dangerous, so it is not a good idea to overload with it. Some foods that are rich in potassium are dried figs, seaweed, nuts, bananas, spinach, and beef.

If there is a potassium deficiency in a person’s blood, muscles in the lip and elsewhere in the body can start to twitch. Potassium is needed to conduct and transmit nerve impulses to the muscles. Fasciculations can also be caused by an imbalance in electrolytes.
