The Office on Women’s Health lists the following symptoms for this condition: fatigue; weakness; dizziness; headaches; low body temperature; pale skin; rapid or irregular heartbeat; shortness of breath; chest pain with physical activity; brittle nails; and unusual cravings for ice, very cold drinks, or non-food items such as dirt or paper.
