Can Iron Deficiency Cause Heavy Periods?

Iron deficiency doesn't cause heavy periods, but heavy periods commonly cause iron deficiency. This creates a problematic cycle where heavy menstrual bleeding depletes iron stores, leading to anemia. Studies show that 20-60% of women with heavy periods develop iron deficiency anemia. Heavy periods are defined as bleeding lasting more than 7 days or requiring pad/tampon changes every hour. Iron deficiency symptoms include fatigue, weakness, pale skin, and shortness of breath. If you experience both heavy periods and these symptoms, blood tests can measure your iron levels, hemoglobin, and ferritin to confirm deficiency.
