Brief Answer:
Increased demand, increased loss & decreased absorption- causes of iron deficiency

Detailed Answer:
Hello,
Thanks for posting your query on Health Care Magic.

Iron depletion from body can occur due to various causes:
1. Increased demand for iron
2. Increased loss of iron from body
3. Decreased absorption of iron from intestines

Iron deficiency leads to iron deficiency anemia which is characterized by tiredness, fatigue, decreased concentration etc.

Preliminary investigations are required if iron deficiency is suspected - Complete hemogram, Reticulocyte count and Iron studies.

Management of iron deficiency includes iron supplements till iron stores are replenished.
The underlying cause for iron deficiency needs to be identified and thus cured.

Let me know if you have any further queries..

Thanks and take care
Dr Shailja Puri
