What reason is limb spasm

First: fatigue: during the day, excessive exercise or exertion of the legs causes fatigue. At night, the state of muscle tension has not been improved. Too many metabolites can not be consumed in time. Its stimulation can cause leg cramps.

Second: cold: when sleeping at night, cold feet and legs can cause leg muscle spasm. Blood flow factors: for patients with varicose veins or deep venous thrombosis in the legs, if they stay in a certain position for a long time during sleep, the veins in the legs will be compressed and the backflow will be blocked, resulting in blood stasis. When the blood stasis reaches a certain degree, it will cause leg muscle spasm.

Third: hypocalcemia: when hypocalcemia occurs in the body, the excitation threshold of neuromuscular junction is reduced, which is lower than the stimulation intensity under normal conditions. That is to say, it can make neuromuscular excited, so it is very easy to produce abnormal contraction, causing leg cramps. This situation is more common in pregnant women and the elderly with calcium deficiency.
