A high blood sedimentation rate of 23mm/h can be caused by menstruation, nephritis, endocarditis and other diseases. Sedimentation value should be less than 15mm/60min for men and less than 20mm/60min for women. Therefore, sedimentation value of 23mm/h is on the high side, which can be caused by physiological and pathological reasons. 1. If a woman is in the menstrual period, the blood sedimentation may be physiologically elevated due to the relative concentration of blood caused by massive bleeding. After menstruation is over, the blood sedimentation value will gradually return to normal. No special treatment is needed in this case. 2. If the blood sedimentation value is high for a long time, it is considered to be caused by pathological factors, such as suffering from nephritis, endocarditis, cirrhosis, rheumatic fever, tuberculosis, cholecystitis, sepsis and other diseases. In this case, the patient can follow the doctor to conduct other tests to clarify the cause of the disease. When the condition gradually improves, the blood sedimentation value will then return to normal. If the blood sedimentation value is high, it is recommended to go to the hospital in time for relevant examinations to clarify the diagnosis, and actively treat under the guidance of the doctor.
