In most cases, the menstrual flow will be small, but if the patient has a concurrent blood disorder or is taking anticoagulant medication, this may lead to an increase in menstrual flow.
The essence of menstruation is the cyclic shedding of the uterine lining leading to bleeding, so when the endometrium is thin, the amount of bleeding may be less, but if the menstrual flow is 20-60ml is normal.
However, the relationship between the thickness of the endometrium and the amount of menstruation is not absolute. If the patient has a blood system disease, such as hemophilia, or if the patient has been taking anticoagulant drugs for a long time, such as aspirin, etc., when such patients have their menstrual period, even if the endometrium is thin, they may still have heavy bleeding.
Patients who have abnormal menstrual flow need to seek regular medical treatment, complete relevant examinations, identify the cause of the disease under the guidance of a professional doctor, and follow the doctor’s instructions for targeted treatment.
