Overview
History
Symptoms
Symptoms of iron deficiency can occur even before the condition has progressed to iron deficiency anemia.
Symptoms of iron deficiency are not unique to iron deficiency (i.e. not pathognomonic). Iron is needed for many enzymes to function normally, so a wide range of symptoms may eventually emerge, either as the secondary result of the anemia, or as other primary results of iron deficiency. Main symptoms of iron deficiency include:
In severe cases, dyspnea can occur. Unusual obsessive food cravings, known as pica, may develop. Hair loss and lightheadedness can also be associated with iron deficiency anemia
Other symptoms patients with iron deficiency anemia have reported are:
- Constipation
- Tinnitus
- Palpitations
- Seeing bright colors

- Depression

- Twitching nerves, tingling, numbness

- Slow social development
