Complementary therapies
C |
There is evidence
from two systematic reviews suggesting that high frequency TENS,
acupuncture, vitamin B1 and magnesium may help to relieve dysmenorrhoea
( Proctor et al., 2002;
Proctor and Murphy, 2001).
One RCT has shown that vitamin E may relieve primary dysmenorrhoea
and reduce blood loss ( Ziaei
et al., 2005). Whether such treatments are effective in endometriosis
associated dysmenorrhoea and heavy bleeding is unknown. |

Many women with
endometriosis report that nutritional and complementary therapies
such as homeopathy, reflexology, Traditional Chinese Medicine,
herbal treatments, etc, do improve pain symptoms. Whilst there
is no evidence from RCTs in endometriosis to support these treatments,
they should not be ruled out if the woman feels that they could
be beneficial to her overall pain management and/or quality of
life, or work in conjunction with more traditional therapies. |
Many consumers are now seeking complementary therapies
over conventional medicine. In the field of menstrual disorders, there
is some support for this approach from a systematic review suggesting
that nutritional intake and metabolism may play an important role in
the cause and treatment of such problems (Proctor
and Murphy, 2001).
In three double-blinded, but small, RCTs it was shown
that magnesium was more effective than placebo for pain relief and the
need for additional medication was less (Davis,
1988; Fontana-Klaiber and
Hogg, 1990; Seifert et
al., 1989). The largest of these trials (n=50) also reported that
women taking the magnesium therapy had substantially lower levels of
PGF2-al in their menstrual blood than those on placebo (p<0.05),
which mirrored the therapeutic decrease in pain experienced by the participants
(Seifert et al., 1989).
Overproduction of PGF2 has been shown to be a substantial contributing
factor to the painful cramps associated with dysmenorrhoea. This emphasises
the potential biological rationale behind magnesium therapy for dysmenorrhoea,
as magnesium inhibits the biosynthesis of PGF2-a as well as having a
role in muscle relaxation and vasodilation (Altura
and Altura, 1985; Reavely,
1998).
Vitamin B1 plays an important role in metabolism and
deficiency can result in fatigue, muscle cramps, various pains, and
a reduced tolerance to pain, which are all factors that can be associated
with dysmenorrhoea (Reavely,
1998). This may be why one large trial (n=556) showed a daily intake
of 100mg of vitamin B1 for two months to be an effective treatment for
dysmenorrhoea, with none of the women taking placebo experiencing complete
pain relief (Gokhale, 1996).
In a randomised controlled trial 278 girls aged 15-17
with primary dysmenorrhoea were given 200 units of vitamin E or placebo
twice a day, beginning two days before the expected start of menstruation
and continued through the first three days of bleeding over four consecutive
menstrual periods. At four months, the vitamin E group had lower pain
severity assessed by visual analogue scale (0.5 vs. 6, p>0.001),
shorter pain duration (1.6 hours vs. 17 hours, p>0.0001) and reduced
blood loss assessed by pictorial blood loss assessment chart (46 vs.
70, p>0.0001). (Ziaei et al.,
2001).
Another systematic review concluded that transcutaneous
electrical nerve stimulation (TENS) and acupuncture can be effective
in the treatment of dysmenorrhoea. Though there was insufficient evidence
to determine and assess the treatments accurately, the reviewers concluded
that TENS represents a suitable alternative for women, who prefer not
to use medication or wish to minimise their intake of NSAIDs (Proctor
et al., 2002).
Whether any of these treatments are effective in endometriosis
associated dysmenorrhoea has not been shown.
Proctor et al highlight that one small but methodologically
sound trial of acupuncture suggests benefits for this modality (Helms,
1987), and in a retrospective study of 47 families with paediatric
pain patients (median age 16, 6 of whom were diagnosed with endometriosis)
70% felt the treatment helped their symptoms (Kemper
et al., 2000).
A randomised controlled trial of 90 women with endometriosis
compared Shu-Mu acupuncture (n=30), routine needling acupuncture (n=30)
and oral Danazol (n=30). The total effective rate was similar in the
three groups, however the Shu-Mu point combination group was superior
to the other two groups in improvement of dysmenorrhoea and irregular
menstruation, and serum CA125 in the Shu-Mu point combination treated
group was significantly decreased (Sun
and Chen, 2006).
Extending the therapeutic network
Given the chronic and stubborn nature of endometriosis,
there may be times when it can be beneficial to extend the therapeutic
network beyond the medical mainstream; especially when women report
that nutritional and complementary therapies, such as homeopathy, reflexology,
Traditional Chinese Medicine (TCM), herbal treatments, physiotherapy,
etc, improve their pain symptoms.
Whilst there is no evidence from any of the above
to support these treatments in endometriosis related symptoms these
should not be ruled out if the woman feels that they are beneficial
to her overall pain management and/or quality of life.
Nutritional therapy/dietry modification
Nutritional therapy/dietry modification has shown
promising effects on dysmenorrhoea in three small RCTs, specifically
supplementation with omega-3 fish oil combined with vitamin B12 and
a diet high in vegetables and low in animal fats (Harel
et al., 1996; Deutch et
al., 2000; Barnard et al.,
2000). Parazzini et al found that intake of fruit and green vegetables
decreased the risk of endometriosis, whereas ham, beef and other red
meat increased the risk (Parazzini
et al., 2004), Several studies also link fibre intake to an increased
oestrogen excretion (Rose et al.,
1997; Kaneda et al., 1997).
An RCT of 80 women with endometriosis demonstrated
that two months of high-dose vitamin E and C therapy was associated
with significant improvement in endometriosis pain and a reduction in
inflammatory markers (Santanam
et al., 2003). Another two randomized, double-blinded, placebo controlled
trials have demonstrated significant decrease in median pain scores
in the groups treated with vitamin E compared to placebo for primary
dysmenorrhoea (Butler et al.,
1955; Ziaei et al., 2001;
Ziaei et al., 2005).
Homeopathy
In a very small, non-randomised, study in eight patients
diagnosed with endometriosis, five out of seven, who had dysmenorrhoea,
reported relief from symptoms (and two had intermittent relief) following
individualised homeopathic treatment (Hunton,
1993).
Herbal remedies/Traditional Chinese Medicine
A systematic review (Proctor
and Murphy, 2001) concluded that there was insufficient evidence
to recommend the use of the herbal remedies considered in the review.
One small trial, however, showed that a herbal combination was more
effective for pain relief than placebo and that less rescue medication
was needed by the treatment group (Kotani
et al., 1997).
A randomised controlled trial, which compared Yiweining
(YWN) with Gestrinone post-operatively showed a recurrence rate of 5.0%
and 5.3% respectively compared with a 30.7% in the placebo group, however,
the adverse reaction rate in the YWN was lower (10.0%) than that in
the Gestrinone group (31.6%) (Yang
et al., 2006).
Furthermore, Qu et al have demonstrated in endometriosis model rats
that the Chinese herb Yiweining (YWN) can prevent the growth of ectopic
endometrium by inhibiting the synthesis and secretion of TNF-alpha,
IL-6, and IL-8 (Qu et al., 2005),
and can reduce the positive expressions of MMP-2 and COX-2 mRNAs (Qu
et al., 2006).
Exercise
Whereas physiotherapy, yoga, Pilates, and gentle exercise
may assist the body in getting back into shape during/after prolonged
periods of pain and/or after surgery to strengthen compromised pelvic/abdominal/back
muscles, and whereas reflexology has anecdotally been reported to relieve
pain symptoms, there is no evidence published relating to their therapeutic
effect on dysmenorrhoea or endometriosis-related symptoms.
Patient support groups
GPP |
Patient self-help groups can provide
invaluable counselling, support and advice. The website www.endometriosis.org/support.html
provides a comprehensive list of all the self-help groups
in the world. Self-management programmes may prove beneficial in
providing the woman with tools to enable her to live with a chronic
disease. |
Patient support groups and self management
Physical and psychological trauma can contribute to
a negative self-image and negative internal dialogue (Stones,
2000). Thus some women with endometriosis may benefit from working
with a counsellor/psychologist, in particular a pain psychologist, to
develop strategies on how to cope with endometriosis including breaking
the pain cycle, dealing with stress and anxiety, and resolve feelings
about infertility.
Self-management (also called the Expert Patients Programme)
is a rigorously researched patient led programme developed by Stanford
University in the United States. Coventry University has researched
self-management in the United Kingdom and their findings support the
Stanford research.
The underlying basis of the course is the symptom/pain cycle, showing
the interaction between disease, fatigue, depression, anger/fear/frustration,
stress/anxiety and tense muscles. The aim of the course is to provide
tools to break the cycle at any given point through weekly sessions
with tutors, who also have chronic diseases (see: http://www.endometriosis.org/best-practise-falconer.html
for more information).
For some women, all they need is to talk to others
with the disease - to share mutual experiences, coping techniques, and
discuss treatment methods. Patient organisations play an important role
in providing women and girls with emotional support, and collaborate
closely with physicians and legislators in providing guidance and information
about the disease. A list of current global resources for support can
be found at: www.endometriosis.org/support.html
