The signs you may be iron deficient

Iron deficiency is a widespread but often underrecognized health issue that can cause symptoms like fatigue and brain fog, even in the absence of anemia. New diagnostic recommendations from the American Society of Hematology aim to improve early detection and treatment.
Why it matters
Increased awareness of iron deficiency is critical for public health, as many patients suffer from symptoms for years before receiving a proper diagnosis.
More people are low in iron than in any other micronutrient, according to the American Society of Hematology. But many live with fatigue, weakness, brain fog and other symptoms for months or years before a deficiency is caught. Nearly one-third of adults in the United States may be iron deficient, according to a 2024 study. And routine screening among children and pregnant women — who are at high risk — may miss more than 70% of cases. Some people online are self-diagnosing, citing dark under-eye circles and pale skin as evidence that they are low in iron. Social media influencers call the look “ferritin face,” named after a protein that stores the element in the body. Iron deficiency is common, prevalent and underrecognized, said Dr. Ariela Marshall, associate professor of medicine at the University of Minnesota.
