In case of iron-deficiency anemia, which of the following might be expected in a patient?

In the context of iron-deficiency anemia, koilonychia, or spoon-shaped nails, is a classic physical finding that may be observed in affected patients. This abnormality occurs as a result of the structural changes in the nails due to insufficient iron, which is critical for various bodily functions, including the development of healthy cells and structures. Koilonychia is specifically characterized by nails that have a concave shape and often feel soft and thin, which reflects an underlying nutritional deficiency.

While other conditions could cause thinning of hair or frequent headaches, these are not specific indicators of iron-deficiency anemia. Normal nail structure would also not be expected in the presence of iron deficiency, making koilonychia a specific and recognizable manifestation of this condition. Thus, identifying koilonychia provides valuable insight into potential iron deficiency and can assist healthcare providers in further evaluating and managing the patient's anemia.
