Imagine trying to tell your muscles what to do but it does what it wants instead, muscles have a mind of their own also, A muscle twitch or spasm is an involuntary contraction of the fibers that make up a muscle. Nerves control muscle fibers. When something stimulates or damages a nerve, it causes the muscle fibers to contract, resulting in a twitch. A person can most times see or feel these twitches below skin.
Twitches and spasms are highly observed in the thighs, calves, hands, arms, belly, ribs, and the arches of your foot. It can occur on part of a muscle, group of muscles or all of it. Doctors are not sure what the causes of twitches are, but a few common things set them off as Fasciculation is the major cause of most twitches.
Strain or muscle overexertion cause spasm and are very common after intense exercises. Muscle fatigue triggers twitching and cramping in overworked muscle fibers, as ion electrolyte balance is altered through excess sweating during exercise. Electrolytes play a key role in stimulating contractile fibers. As ion loss may trigger twitch activities.
The arms and legs are the most likely body regions to experience such muscle twitches especially the calf, biceps and thighs due to exercise over work. However eyelids also feel such spasms when a person is sleep deprived, as brain chemicals send signals from brain to nerves which cause such contractions, also in some cases triggers range from stress and smokes from wind, bright light and excessive caffeine intake but are harmless and soon go away on its own. Twitches in eyelids that don't do away can be due to eye disorders such as glaucoma or a sign of brain and nervous disorders such as Bell's palsy and multiple sclerosis and should be checked upon.
Your muscles in the body depend on minerals, like potassium and magnesium, to work properly. If depleted levels of them, your body sends signals as cramps and spasms. Excess sweating can deplete you as well as certain medications also excess alcohol intake, diarrhea or vomiting can also depletes body electrolyte levels and could cause twitches. Lower body levels of magnesium is referred to as hypomagnesemia, as magnesium helps membrane transport of calcium in the body. The body needs calcium to support proper muscle function, calcium deficiency may cause muscle twitching. and condition is known as hypocalcemia.
Dehydration or diuretics cause loss of body fluid and electrolytes which could cause spasms, When a person does not drink enough water, they develop dehydration which may result to muscle twitching. Muscles also feel weak when there is a limited supply of Vitamin D and this could cause twitching, Causes of vitamin D deficiency include lack of exposure to sunshine and poor diet.
The good news about muscle twitching is it can be managed by energy management, diet, rest as well as medications.
