Acupuncture

What is Acupuncture? How does it work?

Acupuncture involves inserting thin needles into specific acupuncture points on the body.

According to Traditional Chinese Medicine theory, the body has a network of energy channels called meridians, and acupuncture helps to balance the flow of energy, or Qi, through these meridians. There are 12 meridians and 8 extra ordinary meridians. There are over 364 acupuncture points along the meridian points, which have their own names and functions. 

There are also modern theories about how acupuncture works. One theory is that the needles stimulate nerve fibres, which sends signals to the brain to release natural pain-relieving chemicals, such as endorphins [1, 2]. Acupuncture may also stimulate the release of other substances that promote healing, such as serotonin and dopamine [1, 2].  Therefore, by stimulating specific points, acupuncture may help to regulate the flow of these signals, which can promote healing and relieve pain.

While the exact mechanisms behind acupuncture are still being studied, there is growing evidence to support its effectiveness for a range of conditions [2].

What can Acupuncture help with?

Acupuncture can support a wide range of conditions and symptoms, from pain management, musculoskeletal, neurological and digestive disturbances to mental health [3].

In fact, the World Health Organisation (WHO) [3] has a list  31 symptoms, conditions and symptoms that have been shown in randomised controlled trials to be treated effectively by acupuncture:

  • Pain Management: low back pain, neck pain, sciatica, tennis elbow, knee pain, facial pain, sprains, and pain due to endoscopic procedures. 

  • Musculoskeletal: frozen shoulder, osteoarthritis, and rheumatoid arthritis. 

  • Neurological: bell's palsy, post-herpetic neuralgia, and stroke rehabilitation. 

  • Gastrointestinal: nausea and vomiting (inc. morning sickness), epigastralgia, acute bacillary dysentery, and biliary colic.

  • Other: adverse reactions to radiotherapy and/or chemotherapy, allergic rhinitis (hay fever), essential & primary hypotension, and depression (including depressive neurosis and depression following stroke).​
