What's wrong with the amount of menstruation every time?

Each menstrual flow is less, this situation is not normal, normal menstrual flow within 20 ml to 60 ml is normal, if the menstrual flow is obviously too small, you must do an examination. If less than 20 ml is too little menstruation, you can go to the hospital to do color ultrasound, do sex hormone 6, do thyroid function examination, find out the cause of too little menstruation, and then symptomatic treatment. The cause of menorrhagia is mostly due to ovarian secretion dysfunction, clinical polycystic ovary syndrome, amenorrhea lactation syndrome, or premature ovarian failure, or ovarian secretion of estrogen and progesterone levels will show menorrhagia, need to go to the hospital to do endocrine related testing, and then symptomatic treatment. If it is caused by qi stagnation and blood stasis or qi and blood deficiency, it may also show too little menstruation, need to go to the hospital for syndrome differentiation, and then symptomatic treatment, and then intrauterine adhesions will also show too little menstruation.
