Will the hemoglobin level during menstrual examination be low

Menstrual physical examination may result in low hemoglobin levels, but in most cases it is a normal physiological phenomenon. During menstruation, women may experience a temporary decrease in red blood cell and hemoglobin levels due to shedding of the endometrium accompanied by bleeding. This decrease is usually within the range of 10-20g/L and can recover on its own within 1-2 weeks after the end of menstruation. If the menstrual flow exceeds 80ml (approximately soaked in 16 ordinary sanitary pads) within 3 days before the physical examination, or the hemoglobin value is below 110g/L, pathological anemia may be considered. The hemoglobin test value during menstruation is greatly affected by the day of the menstrual cycle. It is recommended to avoid the peak period of menstrual flow (usually 2-3 days) for physical examination. For those who have a significant decrease in hemoglobin during menstruation for a long time, it is recommended to improve serum ferritin, vitamin B12 and other tests to exclude iron deficiency anemia or megaloblastic anemia.

During menstruation, attention should be paid to increasing the intake of iron rich foods such as animal liver and lean meat, avoiding strong tea and coffee that affect iron absorption, and maintaining 7-8 hours of sleep per day. If there are obvious anemia symptoms such as dizziness and fatigue, or if the hemoglobin level is below normal for three consecutive menstrual cycles, it is recommended to seek medical attention at the hematology department in a timely manner.
