The symptoms of calf cramps in pregnant women are mostly caused by strain, cold and calcium deficiency. Especially with the increase of pregnancy, the weight of pregnant women will gradually increase, which will lead to the gradual increase of the force on the calf area, thus causing muscle cramps in the calf area. Especially after the cold, it is easy to cause the spasm to aggravate, resulting in the symptoms of calf cramps. Therefore, you can usually do more hot compresses on the calf area and avoid excessive activities on the ground. If the calf cramps are caused by calcium deficiency, pregnant women can eat more calcium-containing foods such as shrimp, soy products, dairy products, fresh fruits, vegetables, sesame and other foods to promote the absorption of calcium, and more outdoor activities. At the same time, you can take oral calcium tablets and vitamin D to relieve the symptoms of leg cramps.
