4. Pale or Lifeless Skin Tone
The skin is the largest organ in the body, and it requires sufficient oxygen flow within the body to maintain a healthy appearance. With diminished hemoglobin production, the skin loses its luster and glow, and begins to take on a lifeless, grey tone.
Iron deficiency affects the skin in many different ways. Blotchy, discolored, or dry skin are all examples of skin disorders that occur due to a lack of iron and low hemoglobin production. Check the inside of your gums and lips; they should be a natural red color. If you notice that the coloring is less red and looks grey or ashen, you could be suffering from low levels of iron.
The skin is a useful marker to monitor the treatment of your iron deficiency. In the first place, you will notice the recovery is in your face and skin tone as levels of the iron rise to a healthy balance and hemoglobin production restored to optimal levels.
