Both men and women can have problems with foot cramps. Foot cramps are actually due to muscle spasms called cramps, and the lower extremities are indeed more prone to muscle spasms. The reason for muscle cramps is that this one muscle, which has undergone ischemia or hypoxia, because the muscle contraction is affected by calcium, or there is a fluctuation of calcium ions, can lead to cramps in this muscle. There are various reasons for foot cramps, such as ischemia, poor blood circulation after staying in one position for a long time may lead to leg cramps, or after strenuous exercise, sometimes changes in the local blood supply can also occur leg cramps, medical more common because of calcium ion deficiency can also lead to cramps. It is generally more common in menopausal women or older men and women because calcium absorption is affected and there is more bone loss at the same time. Overall, the body’s calcium reserves are reduced and may be more prone to cramping. So if it happens in older women you need to be especially alert and go to the hospital to check for osteoporosis.
