Why iron binding increases in microcytic hypochromic anemia?

Iron-binding capacity (IBC) is a measure of the amount of iron that can be bound to transferrin in the blood. In microcytic hypochromic anemia, the red blood cells are smaller than normal and have less hemoglobin, which is the oxygen-carrying protein. This can be caused by a number of factors, including iron deficiency.

When the body does not have enough iron, it can't make enough hemoglobin. This leads to microcytic hypochromic anemia. The body tries to compensate for this by increasing IBC, which allows it to bind more iron to transferrin. This increased IBC can help to increase the amount of iron that is delivered to the red blood cells, which can help to improve the symptoms of anemia.

However, increased IBC is not a cure for microcytic hypochromic anemia. The underlying cause of the anemia must be treated in order to correct the condition. In most cases, this means taking iron supplements.
