Summary

Story summary

Iron deficiency affects over one in four Americans and impairs oxygen transport.
Symptoms include fatigue and weakness as the body prioritizes blood flow to vital organs.
Hair thinning, cold extremities, brittle nails, pale skin, and mood changes occur because iron supports neurotransmitter production.
In severe cases, iron deficiency can lead to pica, a craving for non-nutritive substances.
Rarely, it can result in Plummer-Vinson syndrome, which complicates swallowing.
