| Iron Deficiency and Anemia May Be More Common Than We Know | 06 Dec 2024 | 00:10:59 | |
Low iron levels can cause fatigue and impact mental health, but doctors often miss cases of iron deficiency and anemia. Pediatric hematologist Angela Weyand, a clinical associate professor at the University of Michigan Medical School in Ann Arbor, points to one population that could be at a higher risk—young women with heavy menstrual bleeding. In one study from a national database, nearly 40 percent of otherwise healthy adolescent women were iron-deficient, and 6 percent were additionally anemic. Awareness and self-advocacy could help people receive accessible and inexpensive treatments for low iron levels.
