Eye spasms, also known as eyelid twitches, occur when a muscle in your eyelid causes your eyelid to make small, uncontrollable movements. The spasms do not necessarily indicate a serious medical condition, but if you have low levels of magnesium in your system, an eyelid twitch may occur. Talk to your doctor if you have frequent episodes or a twitch that does not resolve, and she will help you determine the cause and formulate a treatment plan if necessary.
Causes
Low magnesium levels in your blood may contribute to eyelid twitches, but other factors may have a role as well. If you consume a significant amount of caffeine or alcohol or if you smoke, this may result in twitches. Also, eye irritation from conditions such as dry eye or an eye infection could contribute to an eyelid spasm, and fatigue and stress also play a role in twitching.
Magnesium
Magnesium plays essential functions throughout your body by aiding in chemical reactions, maintaining your heart rhythm and promoting a healthy immune system. This nutrient also helps your muscles function properly and low levels could result in muscle spasms, including the muscles of your eyelids and eyes. Other signs of a deficiency include upset stomach, weakness, tingling and numbness and seizures.
The average adult requires between 310 and 420 mg of magnesium each day. Food sources include halibut with 90 mg in a 3-oz. serving and potatoes, which average around 50 mg. Other foods include nuts, beans, rice, lentils and milk.
Treatment
An eyelid spasm from low magnesium levels requires you to increase your magnesium intake. Your doctor may recommend a daily goal for magnesium, and he may recommend that you use supplements or diet depending on the severity of your deficiency.
Eyelid twitches from other causes typically resolve on their own within a few days, but the spasms could last for a few weeks. This does not typically indicate a serious condition, but if you have a spasm that causes your lid to close completely or if you have twitching elsewhere or that causes pain or other symptoms, contact your doctor immediately.
Considerations
You should not begin taking magnesium supplements or increasing your intake without first consulting your physician. High intakes of nutrients could interfere with medications or health conditions you have, and your doctor will determine a safe intake level based on your general health.
