A third of young U.S. women now classed iron deficient

Original: 34% of U.S. women under age 50 have iron deficiency under new guidelines

New clinical thresholds for ferritin, the key marker of iron stores, would classify about 34% of U.S. women under 50 as iron deficient. Under older, looser cutoffs many of these cases went undiagnosed despite symptoms like fatigue. Discussion online centres on how lab reference ranges have masked a widespread, underrecognised deficiency and what the revised standards mean for screening and treatment.

Why now: The finding that roughly one in three young women may be iron deficient challenges long-standing diagnostic thresholds, prompting debate among clinicians and patients.
