How to Spot Iron Deficiency

How to recognize the signs of iron deficiency?

Symptoms

• Symptoms of iron deficiency include fatigue and a lack of stamina. This is the result of fewer and paler red blood cells and a reduced ability of these cells to hold and carry oxygen.

• Iron deficiency in children has been reported to produce psychological problems, learning disabilities, hyperactivity, decreased attention span, and a lowered IQ as well as anemia.

• Other common iron deficiency symptoms are headaches, dizziness, decreased appetite, weight loss, constipation, and a weakened immunity.

• Anemia manifests itself as pallor of the skin, cheeks, lips, and tongue.

• Canker sores in the mouth, hair loss, brittle nails, and itching are other common symptoms.

• People who suffer from iron deficiency will sometimes have unusual food cravings, which promptly disappear after iron supplementation is successful.

• In children, iron deficiency may cause a strange symptom called “pica,” a term which refers to the eating or chewing of inedible objects such as toys, clay, or ice. Iron treatment stops the behavior.

Iron deficiency can be confirmed by blood tests, the most sensitive of which is the serum ferritin level.
