Iron-deficiency anemia is anemia caused by a lack of iron. [3] Anemia is defined as a decrease in the number of red blood cells or the amount of hemoglobin in the blood. [3] When onset is slow, symptoms are often vague such as feeling tired, weak, short of breath, or having decreased ability to exercise. [1]
Latent iron deficiency (LID), also called iron-deficient erythropoiesis, [1] is a medical condition in which there is evidence of iron deficiency without anemia (normal hemoglobin level). [2] It is important to assess this condition because individuals with latent iron deficiency may develop iron-deficiency anemia.
Nutritional anemia can be caused by a lack of iron, protein, vitamin B12, and other vitamins and minerals that are needed for the formation of hemoglobin. However, Iron deficiency anemia is the most common nutritional disorder. [7] Signs of anemia include cyanosis, jaundice, and easy bruising. [7]

Nearly half of all anemia cases are due to iron deficiency as it is the most common nutritional disorder. [4] Although it is a common nutritional disorder, most causes of iron-deficiency anemia (IDA) are due to blood loss. [4] It occurs most commonly among children and females who are menstruating but can happen to any individual of any age. [3]
Individuals with TEC have a median age of presentation of 18–26 months; however, the disorder may occur in infants younger than 6 months and in children as old as age 10 years. Because of the gradual onset of the anemia, children are often healthier than expected from their low hemoglobin levels. [citation needed]
