Foot cramps during pregnancy can be relieved by calcium supplementation, paying attention to warmth, avoiding prolonged standing and appropriate activities. 1. Patients can usually consume more milk and other foods containing calcium and iron, and sunbathe to promote the absorption of calcium, while calcium supplements can be taken under the guidance of the doctor. 2. Pay attention to the warmth of the lower limbs while sleeping, and soak your feet in warm water. 3. Avoid sitting or standing for a long time. If you are lying down, raise your feet slightly and stretch your toes upward to stretch the muscles at the back of the calf. 4. If you are having cramps, you can slowly hook your toes back and slowly straighten your knees to relieve the cramps. It is recommended that patients with persistent foot cramps should go to the regular hospital in a timely manner, and follow the doctor’s instructions for symptomatic treatment.
