Which of the following is a symptom of iron deficiency anemia?

Pica is a notable symptom associated with iron deficiency anemia. It refers to the compulsive craving and consumption of non-nutritive substances, such as dirt, clay, or chalk. This behavior is often observed in individuals with iron deficiency and reflects an underlying disruption in the body's craving mechanisms, potentially due to a lack of essential nutrients like iron.

In the context of iron deficiency anemia, the body may drive individuals to seek out these non-food items in an attempt to compensate for nutritional deficiencies. While fatigue and dizziness can also occur with iron deficiency anemia, they are more general symptoms that may be linked to various other conditions as well. Therefore, pica stands out as a distinctive symptom specifically associated with iron deficiency anemia, highlighting the unique physiological response to iron deficiency.
