The neurologist listed the causes of involuntary muscle contraction

Physical overexertion, lack of sleep, an abundance of caffeine – all this can cause involuntary muscle contractions. In an interview with MedikForum, neurologist Vladimir Erokhin spoke in more detail about the causes of uncontrollable muscle twitches or spasms.

Physical overload. According to the doctor, physical overexertion can cause electrolyte imbalance due to profuse sweating. The loss of electrolyte in the muscle fibers causes them to contract, contributing to the characteristic sensation in the muscles.

Lack of sleep. Brain chemicals (neurotransmitters) carry information from the brain to the nerves that control muscle contraction. Lack of sleep can affect the functioning of neurotransmitter receptors, resulting in less control over muscle contractions. Very often, with a lack of sleep, muscle spasms of the eyelids occur.

Caffeine. Drinking too much coffee, tea, or caffeinated energy drinks can also lead to muscle twitches and spasms. Caffeine is a stimulant, and. when too much of it accumulates in the human body, it can stimulate muscle contractions in almost any part of the body.

Calcium deficiency. The human body physiologically needs calcium to maintain proper muscle function. Its deficiency (hypokalemia) is a common cause of muscle cramps.

Magnesium deficiency. Magnesium also plays an important role in healthy nerve and muscle function by helping transport calcium across cell membranes. Its deficiency can cause muscle spasms almost anywhere in the body, including the heart.

Vitamin D deficiency. Nerves need this vitamin to carry messages from the brain to the muscles. One of the consequences of vitamin D deficiency is muscle weakness and cramps.

Medicines. Some medications cause involuntary muscle contractions, which may occur as a side effect or be due to interactions with other medications.

In addition, muscle twitches can be the result of dehydration, anxiety, and stress.
