Anemia may cause a decrease in menstrual flow as well as delayed menstruation, and in severe cases it may lead to amenorrhea. However, if the anemia is caused by nutritional disorders, excessive menstruation may occur.
Anemia is a state in which the body’s peripheral blood red blood cells are reduced below the normal range and thus accompanied by clinical symptoms. It may affect the hypothalamic-pituitary-ovarian axis, and in some cases may lead to decreased menstrual flow, or delayed menstruation or amenorrhea.
However, some anemias have a tendency to bleed, such as megaloblastic anemia, which can cause thrombocytopenia and the possibility of bleeding, leading to increased menstrual flow.
Therefore, anemia may decrease or increase the menstrual flow. It is recommended to consult a doctor in time to find out the cause of the decrease in menstrual flow and actively cooperate with the doctor for treatment.
