Signs and Symptoms of Iron Deficiency
Too little iron can impair body functions, but most physical signs and symptoms do not show up unless iron deficiency anemia occurs. Someone with early stages of iron deficiency may have no signs or symptoms. This is why it is important to screen for too little iron among high risk groups.
Signs of iron deficiency anemia include:
- Feeling tired and weak
- Decreased work and school performance
- Slow cognitive and social development during childhood
- Difficulty maintaining body temperature
- Decreased immune function, which increases susceptibility to infection
- Glossitis (an inflamed tongue)
