Fluctuations and interrelationship of oxidative stress and hepcidin during the menstrual cycle.

Summary: Women lose iron during their monthly periods. This natural process can cause stress on the body's cells, known as "oxidative stress." A hormone called hepcidin helps control the body's iron levels. This study looked at 12 women to see how cell stress and hepcidin change during the menstrual cycle. Researchers found that cell stress goes up during the bleeding and early phases of the cycle, especially in women with low iron. However, hepcidin levels did not change much over the month. Ultimately, the study showed no direct link between cell stress and hepcidin levels in the blood.
