Because the signs and symptoms of iron deficiency (also termed anemia, iron deficiency anemia, sideropenia, and hypoferremia) can be very subtle, only a blood test can tell you for sure if your iron levels are too low. Anemia, which has several definitions, including a depletion of functioning red blood cells, can result from iron deficiency as well as other causes. However, some people with iron deficiency anemia have no recognizable symptoms at all. If the iron deficiency develops over a long time, causing an anemia that develops gradually, the body can adjust to the new state and you may not feel any symptoms.
Even when symptoms of chronic, or long-term, iron deficiency are present, the symptoms are nonspecific and could be caused by a number of different problems.
- Symptoms such as pallor, fatigue, and shortness of breath are characteristic of anemia but can also occur with a range of different medical problems.
- Some individuals can exhibit muscle weakness, a decline in motor skills and mental changes such as memory loss.
