Menstruation is a complex and coordinated physiological phenomenon performed by women under the domination of the cerebral cortex, and is most closely related to the nervous and endocrine systems. Acupuncture during menstruation is prone to discomfort due to changes in the symptoms of the above systems, and therefore acupuncture treatment is not recommended during menstruation. During menstruation, due to the discharge of large amount of menstrual blood, the relative lack of qi and blood in the relevant organs and meridians, the reduced adaptability to external stimuli and weakened resistance, the combined sensations of soreness, numbness, swelling, heaviness, pain and wandering produced by acupuncture make it difficult for patients to adapt, thus causing mental tension and emotional instability, breaking the inherent balance and normal rules of menstrual physiological phenomena, leading to menstrual disorders, such as early menstruation or delayed menstruation. In addition, because the action of acupuncture can unblock the meridians and promote the flow of qi and blood, it may cause excessive menstrual flow and anemia, etc. Also, acupuncture treatment sometimes exposes certain parts of the body, which can easily catch the wind and cold and lead to colds. If the menstrual cycle, color and volume are very abnormal, or if you suffer from gynecological conditions such as amenorrhea, dysmenorrhea or menorrhagia, in order to regulate menstruation and relieve pain, menstrual acupuncture treatment needs to be strictly regulated under the guidance of a professional doctor if necessary.
