Two researchers (Lund I & Lundeberg T) have published an article in the March edition of Acupuncture in medicine : journal of the British Medical Acupuncture Society that discusses pain from a biological and gender perspective.
The researchers noted in their abstract that:
“Pain is a unique personal experience showing variability where gender and sex related effects might contribute. The mechanisms underlying the differences between women and men are currently unknown but are likely to be complex and involving interactions between biological, sociocultural and psychological aspects.”
They say in their article that painful experimental stimuli are generally reported to produce a greater intensity of pain in women than in men, and that clinical pain is often reported with higher severity and frequency, longer duration, and present in a greater number of body regions in women than in men. Women are also more likely to experience a number of painful conditions such as fibromyalgia, temporomandibular dysfunction, migraine, rheumatoid arthritis and irritable bowel syndrome. With Fibro, 80-90% of sufferers are women.
The researchers note that with regard to biological factors, quantitative and qualitative differences in the endogenous pain inhibitory systems have been implicated as possible causes of these differences, as well as an influence of gonadal (sex) hormones. Psychosocial factors like sex role beliefs, pain coping strategies, and pain related expectancies may also contribute to the differences. The researchers also note that “being exposed to repeated painful visceral events [e.g. period pains and childbirth] during life may contribute to an increased sensitivity to, and greater prevalence of, pain among women.”
The researchers concluded that:
“When assessing the outcome of pharmacological and non-pharmacological therapies in pain treatment, the factors of gender and sex should be taken into account as the response to an intervention may differ. Preferably, treatment recommendations should be based on studies using both women and men as the norm. Due to variability in results, findings from animal studies and experiments in healthy subjects should be interpreted with care.”
Other research has suggested that repeated or severe exposure to pain can cause a change in the way the brain works, leading to a lower pain threshold and hypersensitivity to pain. It is one of, or part of, the theories about what causes Fibro – the traumatic trigger event causes the brain to effectively “re-write” how it works. It is an interesting idea that the reason more women get Fibro and other chronic pain conditions may be because women are exposed to much more pain from their own bodies throughout their lives. Possibly in the future, it could lead to options of trying to prevent the onset of Fibromyalgia in girls & women who have been found to have a genetic susceptibility to the condition by aggressively managing period pains and the pain from injuries from puberty onwards.
