SymptomsBy Mayo Clinic staff
Initially, iron deficiency anemia can be so mild that it goes unnoticed. But as the body becomes more deficient in iron and anemia worsens, the signs and symptoms intensify.
Iron deficiency anemia symptoms may include:
- Extreme fatigue
- Pale skin
- Shortness of breath
- Dizziness or lightheadedness
- Cold hands and feet
- Inflammation or soreness of your tongue
- Brittle nails
- Fast heartbeat
- Unusual cravings for non-nutritive substances, such as ice, dirt or starch
- Poor appetite, especially in infants and children with iron deficiency anemia
- An uncomfortable tingling or crawling feeling in your legs (restless legs syndrome)
When to see a doctor
If you or your child develops signs and symptoms that suggest iron deficiency anemia, see your doctor. Iron deficiency anemia isn't something to self-diagnose or treat. So see your doctor for a diagnosis, rather than taking iron supplements on your own. Overloading the body with iron can be dangerous because excess iron accumulation can damage your liver and cause other complications.
