Iron deficiency anemia signs and symptoms may include:
Extreme fatigue
Weakness
Pale skin
Chest pain, fast heartbeat or shortness of breath
Headache, dizziness or lightheadedness
Cold hands and feet
Inflammation or soreness of your tongue
Brittle nails
Unusual cravings for non-nutritive substances, such as ice, dirt or starch
