Normal menstruation has a regular cycle (26-32 days) with bleeding that lasts 4-6 days and a consistent flow pattern without clots. An irregular period is any type of bleeding that is abnormal when compared to usual menstrual cycle. This can include an early period, a late period or bleeding between periods. It can also appear as particularly heavy bleeding (menorrhagia) or scanty bleeding. Many women also experience irregular periods in the form of a missed period, continuous periods, or periods that occur twice in one cycle.

Normal period is regulated by woman hormones and irregular menstruation generally related to disruptions in the balance of hormones. A wide variety of factors can be responsible for irregular periods, among them:

  • Significant weight gain or loss
  • Over-exercise
  • Poor nutrition (or a diet too high in carbohydrates)
  • Smoking
  • Drug use
  • Caffeine
  • Excessive alcohol use
  • Eating disorders
  • Increased stress
  • Polycystic ovarian syndrome/estrogen dominance
  • Uterine abnormalities (fibroids/cysts/polyps/endometriosis)
  • Hormonal imbalance related to perimenopause
  • Medications such as hormonal birth control methods
  • Chemotherapy
  • Radiation therapy
  • Recent childbirth, miscarriage, or Diltion and Curettage (D&C)
  • Breastfeeding

Conventional treatment
Hormonal contraceptives are often used to help regulate menstrual cycles. These contraceptives combine estrogen and progesterone and they are available by prescription and come in oral, patch, ring, and injectable forms. If you have a specific hormone problem, such as overproduction of testosterone, hormonal supplements may be able to help regulate your periods. Carbohydrate metabolism abnormalities are often treated with a combination of diet and medications.

Chinese Medicine
Chinese medicine has a long history in the management of irregular period. It a natural approaches to encourage your body to re-establish regular ovulation and to get your hormones back in balance. Although its primary basis rests on empirical evidence, more and more basic researches and clinical trials support its therapeutic modalities in many fields including gynecology. Researches show that acupuncture:

  • Reduce stress hormones responsible for irregular periods
  • Impact on blood levels of follicle-stimulating hormone (FSH), luteinzing hormone (LH), estradiol (E2), and progesterone (P)
  • Accelerate the release of brain and pituitary ß-EP, which inhibits the over-production of GnRH and LH
  • Normalize the hypothalamic-pituitary-ovarian axis, a key process of normal menstruation
  • Promote the function of hypothalamic pituitary-adrenal axis (HPAA) leading to increase in the synthesis and secretion of adrenal steroid hormones, which resets the negative feedback of estrogen to HPOA

In a clinical study, four hundred and five patients with irregular menstruation were enrolled and treated with Chinese herbal formulae Tiaojing Zhixue (n=304) or Fuxuening (n=101). 78.3% and 97.4% of the patients in the two treatment groups restored regular menstruation. Over 80% of patients showed improved clinical symptoms, including reductions in weakness, insomnia and pain. No harmful effects, toxicity or side effects were noticed (Ma K, et al. 2003). Chinese herbal medicine (Xiaoyan Zhixue Capsule) was further reported to treat abnormal uterine bleeding caused by intrauterine devices (IUD) with a 90.3% effectiveness rate, significantly higher than the rate (43.5%) in a control group (Ren JF, et al 2004).
