Rattan tablets, bromocriptine and other drugs can also cause reduced menstruation, and should consult the relevant medical history in detail at the time of consultation.

(2) Gynecological examination: whether there are special abnormalities in the internal and external genitals.

Sexual, adhesion to the uterus, uterine body fixed and backward, uterine isthmus and palpable nodules.

(4) Blood endocrine examination: Inspection items such as T, PRL, FSH, LH, E2, P, etc. are of reference value in the diagnosis of polycystic ovary syndrome, premature ovarian failure, and anovulatory dysfunction. If taking sex hormones, it can affect the blood endocrine report results. ^[6]

Clinical examination with low menstrual flow

Too little menstrual blood is usually drawn for blood tests to check for follicle stimulating hormone, luteinizing hormone, estrogen, prolactin, and progesterone to determine whether the ovarian or pituitary hormone is defective. Secondly, the basal body temperature is plotted to observe whether ovulation or progesterone deficiency occurs. Ultrasound can also be used to detect endometrial thickness and whether ovulation occurs. If it is caused by cervical occlusion due to factor uterine adhesions, it can be separated by hysteroscope and placed in a contraceptive device, and then treated with hormones for 3 months. If progesterone is insufficient, you can add progesterone or use ovarian treatment. Relaxing and reducing stress in your life also helps with normal menstruation.

Distinguishing menstrual flow

Menstruation is a physiological response to periodic uterine bleeding. Generally, the amount of 30 ml per menstrual period is too little, and 180 ml is too much. Normal should be 60 ml each time. This requires us to pay attention to the amount of sanitary napkins used, no more than two packs per cycle. If it is not enough to use three packs of sanitary napkins at a time, each sanitary napkin is soaked, it is too much menstrual flow; on the contrary, if one pack of menstruation is not used up every time, it is too little menstruation, you should go early See a doctor. ^[7]
