Irregular Menstruation (月经不调)

Irregular menstruation refers to abnormality of the menstrual cycle, volume and color, accompanied by other symptoms. It is mostly due to endocrine disorder. Preceded menstruation is called if menstrual cycle is more than 7 days earlier than usual or menstruation occurs twice a month; delayed menstruation is called if menstruation is more than 7 days later than usual or even occurs every 40~50 days; while disorder means menstruation occurs either preceded or delayed without cycle. It is believed in Chinese Medicine the disease is caused by exogenous contraction of cold and heat or seven affects, excessive sexual activity and frequent labor, which lead to dysfunction of qi and blood and impairment of the Chong and Ren meridians.

月经不调是指月经周期，量及颜色异常，伴有其他症状。这主要是由于内分泌紊乱。如果月经周期是比往年提前7天以上或月经一个月出现两次月经之前被调用;如果月经超过7天，比平常晚，甚至出现每40〜50几天之后才月经调用;而紊乱月经意味着无论发生之前或无周期延迟。它在中国医学认为本病是由冷，热，七个影响外源性收缩，过度的性生活，频繁的劳动，这导致冲任经脉气血受损的功能障碍所致。
