10 Causes of Calf Cramps
Reviewed: Dr. Gromatzky
Cause #1: Pregnancy
While the exact cause of why leg or calf cramps occur during pregnancy is still unclear, it is thought to be due to fatigue. When the growing fetus causes enlargement of the uterus, this presses on nerves, leading to decreased blood circulation in the legs. This can be a contributing factor for calf cramps.
Another possible explanation would be due to dehydration, calcium deficiency, or magnesium deficiency. Mostly harmless, those affected can try massaging the calf and flexing the foot by lifting the toes up. It may also be preventable by avoiding standing or sitting for an extended duration, taking calcium or magnesium supplements under the guidance of your healthcare provider overseeing your pregnancy, and staying hydrated.
