Acupuncture for Menopause
The menopause, defined as the end of the last menstrual period, occurs at a median age of 53 years (Hardy 2005). The change in hormone levels during the perimenopause and menopause, particularly the decline in levels of oestrogen, can cause acute menopausal symptoms; for example, about 30-70% of women in Western countries will experience vasomotor symptoms, such as hot flushes and night sweats (Freeman 2007; Melby 2005).
Some women also report vaginal dryness and psychological symptoms, including tiredness, sleep disturbances, mood swings, forgetfulness and loss of libido (Melby 2005; Bachmann 1999). The median duration of menopausal vasomotor symptoms is about 4 years but, in around 10% of women, they last longer than 12 years (Polity 2008).
The most commonly used conventional medical treatment for such symptoms is hormone replacement therapy (HRT), comprising an oestrogen alone (in women who have had a hysterectomy) or in combination with a progestogen. HRT is now only indicated for short-term treatment of menopausal symptoms in the UK (MHRA 2007).
