Lip twitches are unusual and often irritating. They occur when the nerve in your lip struggles to communicate effectively with the muscle controlling it, according to Medical News Today. The facial nerve governs the muscles in the lips, and interestingly, either the upper or lower lip may twitch.
Some causes of lip twitching are benign and can be addressed with simple dietary changes. For instance, excessive caffeine intake might cause your lip to twitch. Caffeine acts as a nervous system stimulant, and consuming over three cups of coffee daily may lead to caffeine intoxication. Symptoms like restlessness, insomnia, or a rapid heartbeat coupled with lip twitches may improve by reducing caffeine consumption. Another possible cause is a potassium deficiency, as potassium facilitates nerve message delivery. A lack of this nutrient can lead to muscle twitches and cramps. Healthline recommends increasing potassium-rich foods if you suspect this to be the cause of your lip twitches.
Other Causes of Lip Twitching
Lip twitches might also indicate other nerve-related issues. Excessive stress may cause facial muscles to become tense.
Prolonged alcohol consumption can also result in a twitching lip, as it may cause nerve damage known as alcoholic neuropathy. This condition can be managed by reducing alcohol intake and using specific medications and vitamins, according to Healthline. Hemifacial spasms and trauma to the brain stem may trigger spasms in facial muscles, including lip twitching. Additionally, medical conditions like Tourette syndrome, amyotrophic lateral sclerosis (ALS), and Parkinson’s disease can contribute to lip twitching (as reported by Medical Health Today).
If you experience additional concerning symptoms alongside lip twitches or if the twitches persist despite trying suggested treatments, consult your doctor without delay.
