Foot pain in pregnant women may be caused by calcium deficiency, weight compression, and impaired circulation during pregnancy. It can be treated by adjusting lifestyle habits and medication. 1. Calcium deficiency during pregnancy: Calcium needs increase during fetal development, and insufficient calcium intake by pregnant women leads to low calcium levels in the body, causing pain in the face. It can be treated with calcium supplementation under doctor’s guidance. 2. Weight compression: Pregnant women gain weight during pregnancy, especially in the second trimester, which puts greater pressure on the feet after exercise and causes foot pain. It can be solved by reducing walking and using a wheelchair. 3. Obstruction of blood circulation: The obvious increase in fetal size during pregnancy will compress the inferior vena cava and the nerves of the lower limbs, causing obstruction of blood circulation in the lower limbs and resulting in foot pain. It can be relieved by bed rest and other means. During pregnancy, pay attention to rest more, at the same time should relax, avoid tension, anxiety, any discomfort should be timely to the hospital, by the doctor to clarify the diagnosis, and cooperate with the doctor to deal with the symptoms.
