Causes, incidence, and risk factors
Iron deficiency anemia is the most common form of anemia . About 20% of women, 50% of pregnant women, and 3% of men do not have enough iron in their body.
Iron is a key part of hemoglobin , the oxygen-carrying protein in the blood. Your body normally gets iron through diet and by recycling iron from old red blood cells. Without iron, the blood cannot carry oxygen effectively. Oxygen is needed for every cell in the body to function normally.
The causes of iron deficiency are:
Poor absorption of iron by the body
Too little ir...
Definition Anemia is a condition in which the body does not have enough healthy red blood cells. Red blood cells bring oxygen to body tissues. There are many types of anemia. Iron deficiency anemia is a decrease in the number of red blood cells in the blood due to a lack of iron. This article focuses on iron deficiency anemia in children. Alternative Names Anemia - iron deficiency - children Causes, incidence, and risk factors Iron deficiency anemia is the most common form of anemia . You get iron through certain foods, and your body also reuses iron from old red blood cells. Iron deficiency (too little iron) may be caused by: An iron-poor diet (this is the most common cause) Body not being able to absorb iron very well, even though you're eating enough iron Long-term, slow blood loss -- usually through menstrual periods or bleeding in the digestive tract Rapid growth (in the first year of life and in adolescence), when more iron is needed Babies are born with iron stored in their bodies.

Iron deficiency is a problem for fifty percent of those who have had gastric bypass surgery and is connected to anemia in one third of the cases. A 1998 study found that women were more than two times more likely than men to have an iron deficiency after weight loss surgery.
Women who are pregnant or having heavy menstruation are most susceptible.
Iron is a critical part of the hemoglobin that carries oxygen in red blood cells. Lack of iron will lessen the production of hemoglobin and cause anemia.
Causes of Iron Deficiency After Gastric Bypass Surgery
Iron deficiency can occur after gastric bypass surgery because the duodenum is bypassed in the procedure. Iron is partially absorbed in the duodenum. Stomach acids draw iron from food and make it more easy to absorb. The small stomach pouch that has been created reduces the amount of acid that is produced which in turn decreases iron ab sorption.
Iron deficiency begins with the exhau...
