13 Subtle Signs of Iron Deficiency You Might Be Ignoring
3. Pale Skin and Pallor

Pale skin, particularly in areas like the face, inner eyelids, and nails, can be a telltale sign of iron deficiency. Hemoglobin gives blood its red color, so low levels can result in a noticeable paleness. This isn't just limited to the skin; it can also affect the color of your gums and the inside of your lips. In some cases, the change in skin tone might be subtle, but it's an important indicator that should not be ignored. If you or someone you know is experiencing unexplained paleness, it may be worth investigating further to rule out iron deficiency.
4. Heart Palpitations
Heart palpitations, or the sensation that your heart is pounding, fluttering, or beating irregularly, can be alarming. While there are many potential causes, low iron levels can be a contributing factor. When iron is deficient, the heart must work harder to deliver oxygen to the body's tissues, which can result in an increased heart rate and palpitations. This is particularly concerning because it can lead to more serious cardiovascular issues if left untreated. If you're experiencing palpitations along with other symptoms of iron deficiency, it's important to seek medical advice to determine the underlying cause.
