What does a low hemoglobin level mean? i was told that my 3 year old sons hemoglobin is low because he drinks to much milk. is this true or is something else wrong. and if so what would it possible be?

Hemoglobin : Hemoglobin is the oxygen carrying component of red blood cells, the main function of red blood cells. A low hemoglobin count means that the hemoglobin count is below average. The body needs iron to produce hemoglobin. Cow's milk is low in iron, which is a necessary element for growth and development. Also, milk decreases the body's ability to absorb iron. Lots of milk means decreased iron decreased iron means decreased hemoglobin levels and decreased oxygenation needed for healthy body growth.

Blood loss vs iron: Kids who consume more than 24-30 oz of milk/day can experience tiny amounts of blood loss thru the intestine due to irritation caused by the cow milk protein on the gut wall. Smaller amounts or boiled milk , don't seem to cause this problem. Blood loss, paired with the kids avoidance of other iron containing foods leads to low hemoglobin production & anemia.Other causes are also possible.
