The effect of acupuncture induced weight reduction on menstrual activity is definitely not a negligible issue. By analyzing the existing materials about the mutual influence of neuroendocrine system and clinical trails, it is known that there exists a close interrelation between acupuncture-induced weight reduction and menstruation. Acupuncture treatment can achieve the effects of weight reduction and menstrual improvement via regulating activities of leptin, thyroid gland system and hypothalamus-pituitary-adrenal cortex axis. Clinical practice has demonstrated that acupuncture stimulation of some commonly-used acupoints for weight reduction also has a favorable regulation on menstrual activity in obesity women.
