Leg cramps may be caused by strenuous exercise, cold stimulation, hypocalcemia, arterial stenosis and other reasons.
1. Strenuous exercise: prolonged over-strenuous exercise leads to long-term tension in the leg muscles, which can cause leg cramps.
2. Cold stimulation: in a cold environment or swimming in the summer when the water temperature is too low, easy to cause leg cold, cold stimulation will lead to leg muscle tonic contraction and cause spasm.
3. Hypocalcemia: the lack of calcium in the body will lead to a decrease in the concentration of calcium in the blood and an increase in the excitability of the muscles, which may lead to spasms in the legs.
4. Arterial stenosis: atherosclerosis, stenosis, and occlusion of the lower limb arteries may lead to ischemia and hypoxia in the legs, causing damage to the local nerves due to loss of nutrients, and causing spasms in the legs.
There are many reasons for leg cramps, it is recommended to consult a doctor in time to identify the cause and then targeted treatment.
