Iron deficiency anemia is a condition characterized by a lack of sufficient iron in the body, leading to a decrease in the production of hemoglobin, which is crucial for transporting oxygen in the blood. This type of anemia is the most common nutritional deficiency and can result from inadequate dietary intake, absorption issues, or increased iron demands during periods like pregnancy. Addressing this condition typically involves the use of specific drugs and dietary modifications to replenish iron levels and restore healthy red blood cell production.
