12 Hidden Signs of Iron Deficiency You Shouldn't Ignore

Pale Skin and Dark Circles

Pale skin is another indicator of iron deficiency, as hemoglobin in red blood cells gives skin its rosy color. When hemoglobin levels drop, your skin can lose its healthy hue, appearing paler than usual. This symptom is often more noticeable in people with lighter skin tones, but it can also be detected in the paleness of the inner eyelids, gums, and nails. Additionally, dark circles under the eyes can become more pronounced due to reduced oxygenation and circulation, leading to a tired and worn-out appearance. These visual cues can serve as a warning sign of an underlying deficiency that needs attention.
