It is not surprising that calcium deficiency is a common cause of leg cramps in the morning, especially among the middle-aged and elderly, who gradually lose calcium as they grow older. You can take oral calcium tablets and consume calcium-rich foods, such as soy products and eggs, which are good for replenishing calcium. In addition to calcium deficiency can cause leg cramps, but also pay attention to the environment and temperature changes, the temperature is too low or lack of sleep quality may also trigger leg cramps. It is best to go to the hospital for a leg checkup to rule out leg cramps caused by inflammation as soon as possible. Leg cramps can be relieved by massaging the legs every day, while keeping warm and increasing calcium substances also need to be done simultaneously.
