High platelet count, wide distribution and small size during menstruation are mostly normal phenomena. 1. High platelet count: Due to the shedding of endometrium during menstruation, which is manifested as bleeding, platelets will reactively increase to avoid excessive bleeding, which is a normal phenomenon, and if there is no obvious uncomfortable symptom, there is no need for special treatment, and it is recommended to closely monitor the blood routine. 2. Platelet distribution width: Platelet distribution width is the discrete degree used to indicate the volume size of platelets in the blood. If the menstrual period is too long, causing chronic blood loss, it will lead to inconsistent distribution of platelet size, resulting in high platelet distribution width, which is a physiological phenomenon. If the patient is worried, it is recommended to review the routine blood test again after the menstrual period. 3. Small platelet volume: due to hormonal imbalance during menstruation, platelets are slightly affected. Low platelet volume alone has no special clinical significance and requires regular rechecking of routine blood tests. During menstruation, there will be slight abnormality in the indicators. If the indicators are too high and you feel unwell, you should go to the hospital for examination in time so as not to miss your condition, and it is recommended that you have a timely recheck after menstruation.
