How can you tell if you have iron deficiency?
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.
On the other hand, if iron deficiency develops suddenly (such as the result of profound blood loss) the body has less time to compensate, and you may notice symptoms of iron deficiency listed below right away.
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.
