Do women with menorrhagia need iron?
British Medical Journal (Clinical Research Ed.)
|April 17, 1982
Summary
Women with heavy menstrual bleeding (menorrhagia) often have low iron stores (serum ferritin) but not necessarily anemia. Prophylactic iron supplements are not routinely needed for these patients.
Area of Science:
- Hematology
- Iron Metabolism
- Women's Health
Background:
- Menorrhagia is a common gynecological complaint.
- Iron deficiency is a frequent complication of heavy menstrual bleeding.
- Anemia is a potential consequence of untreated iron deficiency.
Purpose of the Study:
- To compare hematological indices and serum ferritin levels in women with and without menorrhagia.
- To determine the prevalence of iron deficiency and anemia in women experiencing heavy menstrual loss.
Main Methods:
- Cross-sectional study comparing two groups of women: 42 with menorrhagia and 34 with normal menstrual loss.
- Measurement of hematological parameters including hemoglobin concentration, mean corpuscular volume (MCV), and mean corpuscular hemoglobin concentration (MCHC).
- Assay of serum ferritin concentrations to assess iron stores.
Main Results:
- No significant differences were observed in hemoglobin concentration, MCV, or MCHC between the menorrhagia and normal menstrual loss groups.
- Serum ferritin concentrations were significantly lower in women with menorrhagia compared to those with normal menstrual loss (p < 0.001).
- Despite reduced iron stores, only a small proportion of women with menorrhagia presented with anemia.
Conclusions:
- Women with menorrhagia frequently have depleted iron stores (low serum ferritin) but are often not anemic.
- Routine prophylactic iron supplementation is not indicated for all women complaining of heavy menstrual loss.
- Further investigation into individual iron status may be warranted for women with menorrhagia.
