If the low menstrual flow is due to anovulation, in this case, progestogen withdrawal treatment is needed during the second half of the menstrual period. If the low menstrual flow is caused by damage to the endometrium, such as abortion, hysterectomy, hysterosalpingography or hysteroscopy, further hysteroscopy is needed to clarify the diagnosis and estrogen can be considered to grow the endometrium if necessary. If the low menstrual flow is caused by the destruction of Mycobacterium tuberculosis, in this case, further consultation with the tuberculosis department is needed for treatment. If the menstrual flow is low and the patient does not have fertility requirements, no special treatment may be required for this condition, but only if the basal body temperature is monitored to be biphasic.
