If the amount of menstruation is small each time, it can generally be solved through diet or medication. First, you can go to the hospital for vaginal color ultrasound to observe the thickness of the endometrium. If the thickness of the endometrium is normal, you can drink some brown sugar ginger water or motherwort granules before menstruation and recuperate 7 days before menstruation. If it is caused by stagnation of liver qi, high pressure and depression, you can relax your mood and live a regular life. At the same time, you can take Xiaoyao Pill orally for treatment. If the B-ultrasound indicates that the endometrium is too thin, you can use natural estrogen treatment according to the course of treatment. After regular conditioning, the endometrium will gradually repair and thicken, and the amount of bleeding during menstruation will gradually increase. You can also eat more blood tonic food before and after menstruation to increase the amount of menstruation. If B-ultrasound indicates cervical adhesion, cervical orifice dilatation can be performed due to intrauterine adhesion, and patients with intrauterine adhesion can be treated by hysteroscopy.
