Anemia does not usually cause women to miss their periods. Menstruation is a physiological manifestation of female physiology and is related to changes in estrogen and progesterone levels in the female body. At the end of ovulation, the corpus luteum atrophies, resulting in a decrease in estrogen and progesterone production, which leads to vasoconstriction of the blood vessels under the uterine lining and necrosis of the uterine lining, i.e., the formation of menstrual discharge. Anemia is a decrease in the number of red blood cells in the human blood, with iron deficiency anemia being the most common in women, which usually does not cause changes in the levels of androgen and progesterone in the female body, and therefore does not affect the absence of menstruation. Women with anemia need to go to the hematology department in time to improve the blood routine, erythropoietin measurement, bone marrow aspiration and other related examinations to identify the cause of the disease, and then correct the anemia by treating the cause of the disease. If women have menstrual disorders, they need to go to the gynecology department in time to improve the sex hormone six, gynecological ultrasound and other related examinations to identify the cause of the disease, and then treat the cause of the disease.
