Menstruation is very long not clean how to do

First of all, the menstrual volume between 5-80ml belongs to the normal range, and personal physical differences. If it does not belong to the category of oligomenorrhea, and there is no sudden reduction process, it may belong to the normal physiological volume, and does not necessarily need treatment. For patients with really little menstruation, or sudden significant decrease compared with the previous period, it is necessary to investigate the cause, evaluate the endometrial condition and systemic endocrine condition, and suggest that the hospital should see a doctor for systematic examination, instead of using blood-activating drugs by themselves, treating the symptoms but not the root cause.
