Period pain is a common complaint
|
Acupuncture may be an effective way of easing
severe period pain, a South Korean review of 27 studies suggests.
Researchers said there was "promising evidence" for
acupuncture in treating cramps, but that more work was needed.
In the British Journal of Obstetrics and Gynaecology, they
noted two studies found little difference between real and sham
acupuncture in treating pain.
Acupuncture is a less contentious form of complementary
medicine than some, but its value is still disputed.
Period pain can be severe in some women and may be accompanied
by nausea, diarrhoea, migraine and backache. Common treatments
include pain killers, applying heat and exercise - although a
recent study questioned the efficacy of the latter.
This latest review involved 27 studies - which included nearly
3,000 women. They addressed a variety of forms of acupuncture -
from classical to acupoint injection.
Traditional acupuncturists insert needles in acupuncture points
located along what they describe as "energy meridians" -
a concept for which many scientists say there is no evidence. Sham
acupuncture places needles away from these points.
It is not clear whether either form alleviates pain as a result
of the placebo effect - the very ritual of undergoing acupuncture
- or cause subtle changes in the nervous system and brain activity
which can be beneficial.
Nice backs needles
The analysis by the team from Kyung Hee Medical Centre found
that patients with severe period pain reported a greater reduction
in their symptoms when using acupuncture compared with
pharmacological treatments.
But they stressed there were methodological flaws in some
studies, and that the findings did need to be interpreted with
caution. Nevertheless, there was "promising evidence",
they wrote.
In the UK, the National Institute for Health and Clinical
Excellence (Nice) has backed the use of acupuncture in the
treatment of low back pain - a move welcomed by some but
criticised by those who say there is little evidence for its
efficacy.
The editor-in-chief of the BJOG, Professor Philip Steer, noted
that some women had period pain, also known as primary
dysmenorrhoea, so badly they were "unable to function
normally".
"Women with primary dysmenorrhoea should consult their GPs
or gynaecologists on the best treatment available to them.
Complementary therapies should not be used exclusively, at the
expense of conventional treatment, unless significant improvements
have been made and your doctor tells you otherwise."
