Irregular menstruation refers to abnormal changes in menstrual period, menstrual volume and menstrual cycle of women compared with the past. Patients with irregular menstruation should first go to the hospital for consultation and examination, including checking the hormone level in the basic state, monitoring the basic body temperature, doing ultrasound examination to determine the cause, and then seeking different treatment methods of Chinese and Western medicine.

From the perspective of western medicine, if it is premature ovarian failure, hormone replacement therapy can be used. If polycystic ovary causes menstrual cramps for a period of time, progesterone should be given first. From the perspective of traditional Chinese medicine, the most basic principle is TCM syndrome differentiation and treatment.
