Which is NOT a common symptom of iron deficiency?

Question

BlackTom AI · Accepted Answer

The question asks which option is NOT a common symptom of iron deficiency, so we will evaluate each choice against typical iron deficiency presentations.

Option a: impaired cognitive function. In many cases, iron deficiency, especially in children and adolescents, is associated with cognitive and developmental challenges, making impaired cognitive function a plausible and commonly discussed symptom. Therefore this option could be considered a common symptom.

Option b: growth retardation. While iron deficiency can affect growth, growth retardation is not typically listed as a direct, common symptom across general populations. It is more of a potential consequence or associated outcome in chronic cases, rather than a classic, immediate symptom like fatigue or pallor. This makes it the best candidate for NOT being a common symptom.

Option c: weakness and fatigue. Fatigue and weakness are among the most frequently reported and classic symptoms of iron deficiency due to reduced oxygen transport in the blood. This is a common symptom.

Option d: concave fingernails. Koilonychia (spoon-shaped or concave nails) is a well-known physical sign associated with iron deficiency, particularly in longer-standing cases, and is commonly described in clinical references.

In summary, among the options, impaired cognitive function, weakness and fatigue, and concave fingernails are commonly linked to iron deficiency, whereas growth retardation is less consistently described as a direct, common symptom and tends to reflect longer-term, developmental concerns rather than an immediate, typical symptom. Therefore, growth retardation is the NOT common symptom in many standard listings of iron deficiency signs.
