Acupuncture: a doctor’s approach

Fascia and the body’s electrical network

The most interesting recent development in acupuncture research has been the work on fascia.

Fascia is the connective tissue that encases every nerve, muscle, and organ in the body. It was largely ignored in conventional medicine for decades, treated as inert packaging. We now know it is anything but inert. Fascia is composed largely of collagen, which has piezoelectric properties, meaning it generates electrical charge when mechanically stressed.² This matters because the body’s processes are fundamentally electrical, from nerve impulses, to the heart’s pacemaker, to the membrane potentials that keep cells alive.

Fascia, in other words, is an electrical web that connects the entire body.

A significant finding for acupuncture came from work showing approximately 80 percent correspondence between traditional meridians and connective tissue planes. The connective tissue planes that overlap with meridians have lower electrical resistance, meaning they conduct electricity more efficiently than surrounding tissue.³ This is one plausible mechanism by which inserting needles at specific points can produce effects far beyond the local site of insertion.

Anatomical characterisation of acupuncture points has also shown distinctive features at the cellular and biophotonic levels.⁴ The body, viewed through this lens, looks much more like the integrated electrical network ancient medicine described, and much less like the collection of separate organs conventional medicine tends to assume.

The evidence base for acupuncture is now broad enough to be unambiguous in several areas.

Anxiety. Multiple systematic reviews have shown that acupuncture reduces anxiety symptoms, with mechanistic evidence linking the effect to autonomic nervous system regulation.⁵

Depression. Systematic reviews and meta-analyses have shown meaningful improvement in depressive symptoms, with effect sizes comparable to or exceeding several pharmacological options.⁶

Insomnia. Meta-analyses have shown clinically meaningful improvement in sleep quality and sleep latency.⁷

Fibromyalgia. Meta-analyses have shown acupuncture reduces pain and improves quality of life in fibromyalgia patients, where conventional pharmacological options often reach a ceiling.⁸ Most people I see with fibromyalgia have been on several medications without resolution.

Chronic fatigue syndrome. A network meta-analysis has demonstrated benefit for chronic fatigue syndrome, including improvements in fatigue scores and quality of life.⁹

Chronic pain. A large individual patient data meta-analysis covering over 20,000 patients across multiple chronic pain conditions found acupuncture produces clinically meaningful effects beyond placebo, sustained over 12 months.¹⁰ This is one reason NICE in the UK recommends it for chronic primary pain.

Cancer-related fatigue. Effective enough that it has been integrated into many oncology supportive care protocols.¹¹

Some people in the same setting also ask about intravenous vitamin C.

Other documented areas. Weight regulation,¹² chemotherapy-induced nausea and vomiting,¹³ ischaemic stroke rehabilitation,¹⁴ primary dysmenorrhoea,¹⁵ menopause-related symptoms,¹⁶ and immune function.¹⁷

These are mainstream meta-analyses in mainstream journals, accumulated over the last fifteen to twenty years.

How acupuncture works mechanistically

The mechanistic picture is now well documented.

Autonomic nervous system regulation. Acupuncture modulates the autonomic nervous system, increasing parasympathetic tone, improving heart rate variability, and shifting the body out of sympathetic dominance.¹⁸ This is one of the central mechanisms by which it influences digestion, hormonal regulation, and the stress response.

Blood flow and circulation. Acupuncture stimulates nitric oxide production, which produces vasodilation and enhances circulation in the skin, muscles, and brain. Improved cerebral blood flow has been demonstrated in studies of stroke rehabilitation and cognitive recovery.^{19, 20}

Endogenous opioids and neuropeptides. Acupuncture stimulates the release of endorphins, enkephalins, and dynorphins, alongside non-opioid compounds including serotonin, norepinephrine, oxytocin, and ATP. These contribute to pain modulation and mood regulation, and help explain why effects can be felt in parts of the body distant from the needle site.²¹

Anti-inflammatory effects. Acupuncture promotes anti-inflammatory cytokine production, reducing systemic inflammation in both acute and chronic conditions.²¹

These mechanisms are not exclusive. Acupuncture often works through several pathways at once, which is part of why it can help conditions that span more than one body system.

I read the body through conventional medicine, Traditional Chinese Medicine, and Ayurveda together. Pulse diagnosis helps show which meridians are involved. Modern physiology helps explain which points act on which system. Ayurveda adds the marma points, which were needled in their own tradition long before the West paid attention. That combined picture decides where to needle and why, rather than simply treating the site of pain.
