Autoimmune Dysautonomia

What is Autoimmune Dysautonomia?

Autoimmune dysautonomia is a failure or disturbance of the autonomic nervous system caused by an immune response directed against it. The immune attack can target autonomic ganglia (relay stations), autonomic nerves, or autonomic pathways in the brain.^[1] The autonomic nervous system controls blood pressure, heart rate, breathing, digestion, sweating and pupil size without conscious effort.^[2]

The best-known example is autoimmune autonomic ganglionopathy, in which antibodies against the ganglionic acetylcholine receptor are found in some patients.^{[1, 3]}

Common symptoms

Symptoms depend on which autonomic functions are affected, and can come on over days to months.^[1] Peripheral forms tend to cause loss of function, while central forms tend to cause overactivity.^[1]

• Light-headedness or fainting when standing (orthostatic hypotension)
• Fast, slow or irregular heart rate
• Nausea, early fullness, constipation or diarrhea from slowed digestion
• Too little or too much sweating, and heat or cold intolerance
• Dry eyes and mouth, blurred vision, or pupils that react poorly to light
• Fatigue and trouble concentrating

Some patients also have symptoms outside the autonomic system, including sensory changes and mood or psychiatric symptoms.^[3]

Causes and risk factors

The immune system produces autoantibodies or other immune responses against autonomic structures, but why this happens is not fully understood.^[4] It can occur on its own, alongside another autoimmune disease, or as a paraneoplastic effect of an underlying cancer.^{[1, 4]}

Some autoantibodies carry a high predictive value for cancer, which is one reason a specialist work-up matters.^[1]

How it is diagnosed and treated conventionally

Diagnosis starts with a careful history of how and when symptoms began and progressed, followed by autonomic function testing and blood tests for autoantibodies.^[5] Several other conditions can look similar, including postural orthostatic tachycardia syndrome, chronic fatigue syndrome and long COVID, so a specialist is needed to tell them apart.^[5]

Treatment combines symptom measures with immune therapy when appropriate. Some patients improve with intravenous immunoglobulin, corticosteroids or plasma exchange.^[3] Recognizing an autoimmune cause matters because the disabling symptoms may respond to immune treatment alongside symptomatic care.^{[1, 4]}

Why Autoimmune Dysautonomia calls for a whole-person approach

Autoimmune dysautonomia affects several body systems at once, so symptoms rarely come from one place. Heart rate, blood pressure, gut movement, sweating, energy and mood all depend on autonomic signals.^[2]

Care that pays attention to more than one factor is therefore reasonable, as long as the immune disease itself stays under specialist management.

The immune system and the autonomic nervous system influence each other

The autonomic nervous system regulates immune function, and autonomic symptoms occur in many systemic autoimmune diseases.^[4] This two-way link is one reason researchers look at autonomic balance in immune conditions.

Blood pressure and heart rate control

When autonomic failure is present, blood pressure and heart rate cannot adjust quickly to changes in position.^[2] This produces dizziness and fainting, which carry a risk of falls and injury.

Digestion

The gut has its own nervous system, which is also part of the autonomic network.^[2] Slowed stomach emptying and bowel changes can follow, with nausea, bloating and reduced appetite.^[1]

Fatigue, mood and non-autonomic symptoms

Fatigue and psychiatric symptoms are overrepresented in patients with autoimmune autonomic ganglionopathy.^[3] Stress, sleep and mood therefore deserve attention alongside the physical symptoms.

Acupuncture as supportive care in Autoimmune Dysautonomia

What the research shows

No clinical trials of acupuncture in autoimmune dysautonomia were found in PubMed. Any statement about benefit has to rely on studies of other groups of people, and these apply only loosely.

Two systematic reviews looked at acupuncture and heart rate variability, a measure of autonomic activity, mostly in healthy volunteers or people without autoimmune disease. The earlier review of 12 sham-controlled trials found inconsistent results and no clear evidence of a specific effect.^[6] A later meta-analysis of 9 trials found that real acupuncture increased a marker of parasympathetic activity more than sham acupuncture, but the authors said the quality of the studies and the differences between them called for cautious interpretation.^[7]

A small randomized study in 14 healthy men on bed rest found that daily electrical acupoint stimulation at one point on the wrist partly preserved tolerance of standing up. It does not show an effect in people with autonomic disease.^[8]

For digestive symptoms, a Cochrane review of 32 trials in gastroparesis, nearly all in diabetes, found very low-certainty evidence of short-term benefit compared with drugs, and low-certainty evidence of no difference from sham acupuncture on a validated symptom scale at three months.^[9] This is a different disease, and the results cannot be assumed to carry over.

How acupuncture may work

Researchers propose that acupuncture influences immune function through nerve reflex pathways that connect the body surface with the autonomic nervous system.^[10] This comes from a review of laboratory and clinical work and remains a hypothesis. It has not been tested in people with autoimmune dysautonomia.

What treatment involves

Acupuncture uses fine, sterile, single-use needles placed at points on the body, usually left in place for about 20 to 40 minutes. A short series of visits is followed by reassessment of how you feel. If you are prone to dizziness, fainting or blood pressure drops, tell the practitioner before treatment.

In prospective studies, about 9 in 100 patients had a minor reaction such as bleeding, soreness or redness at a needle site, and serious events occurred in about 1 in 10,000 patients.^[11] Tell the practitioner first if you have a bleeding disorder, take blood thinners, are pregnant, or have a pacemaker (relevant to electroacupuncture). If you take immunosuppressant medicines, mention this too, since your skin may heal differently and your infection risk may be higher.

Ayurvedic medicine as supportive care in Autoimmune Dysautonomia

The Ayurvedic view

Ayurveda has no classical name for autoimmune dysautonomia. Practitioners may describe symptoms such as dizziness, irregular digestion and fatigue as imbalances of Vata, the principle said to govern movement and the nervous system, sometimes with weak digestive fire (agni). These are traditional frameworks, not biomedical diagnoses.

Therapies that may be used

Care is chosen for the individual and, in this setting, is gentle and supportive. It may include:

• Regular meals, sleep and daily routine, and warm, easily digested food
• Gentle oil massage and breathing practices
• Yoga-based practices adapted to your tolerance of standing and movement
• Individually prescribed herbs, subject to the cautions below

Panchakarma, the traditional cleansing program, is not appropriate during pregnancy, acute illness or frailty. Many people with significant autonomic failure, dehydration or low blood pressure are not suitable for it, and it should not be considered without your physician's agreement.

What the research shows

No studies of Ayurvedic treatment in autoimmune dysautonomia were found. Evidence from related areas is limited. In a randomized trial of 97 patients with recurrent vasovagal syncope, a common fainting disorder, those taught yoga had fewer fainting episodes over about a year than those given guideline-directed treatment alone.^[12] A meta-analysis of four studies, two randomized, reported fewer syncope and presyncope episodes with yoga and called for higher-quality trials.^[13] Vasovagal syncope is not autoimmune dysautonomia, so these findings are indirect.

A review of 14 randomized trials of yoga and heart rate variability found mixed results and no convincing evidence of a benefit, and only two of the trials were of acceptable methodological quality.^[14]

Herbal medicine as supportive care in Autoimmune Dysautonomia

Herbs and formulas that have been studied

No clinical trials of Chinese or Ayurvedic herbs in autoimmune dysautonomia were found. Ashwagandha (Withania somnifera), traditionally used in Ayurveda, has been studied for stress and anxiety in general adult populations.^[15] That is a symptom-level question, not a treatment for the immune disease.

What the research shows

A meta-analysis of 12 randomized trials with 1,002 participants found that ashwagandha lowered anxiety and stress scores compared with placebo. The authors rated the certainty of the evidence as low and noted large differences between the studies.^[15] Nothing here shows that herbs affect the course of autoimmune dysautonomia.

Safety and herb-drug interactions

Herbs are active substances, and many people with this condition take immunosuppressants, steroids, blood pressure medicines or heart rate medicines. Herb-drug interactions are documented, including reduced blood levels of ciclosporin and tacrolimus with St John's wort, and extra bleeding when some herbs are combined with warfarin or aspirin.^[16] Herbs can also affect blood pressure and heart rate, which matters when these are already unstable.

Ashwagandha has been linked to liver injury in case series, usually cholestatic with jaundice and itching, and severe outcomes were reported in people with existing liver disease.^{[17, 18]} More broadly, herbal and dietary supplements account for a notable share of drug-induced liver injury in the United States.^[19] Because ashwagandha is also described as an immune-modulating herb in traditional use, and its effect in people with autoimmune disease has not been studied, it should not be used without your specialist's agreement.

In one study, about one fifth of Ayurvedic products bought online contained detectable lead, mercury or arsenic.^[20] Herbs should come from tested sources and be prescribed individually. Tell us if you are pregnant or breastfeeding, or have liver or kidney disease.

Translating traditional medicine into modern biological language

The links drawn here are interpretation, not equivalence. Chinese medicine may describe dizziness, fatigue and poor digestion as qi deficiency or a disharmony of the spleen and heart, and Ayurveda may describe a Vata imbalance. Researchers study things that loosely parallel these ideas: autonomic balance, often measured as heart rate variability, and reflex pathways linking the body surface to the autonomic and immune systems.^{[7, 10]}

No study has shown that a traditional pattern corresponds to a specific autoantibody or autonomic test result.

How this care fits with your medical care

Complementary care for autoimmune dysautonomia is supportive only. For a condition like this, we ask that you are under a physician's care for it and that your treating team knows you are receiving complementary care. Do not stop or change prescribed medicines, including immune therapy and medicines for blood pressure or heart rate, without your prescriber. We do not diagnose or manage the disease itself.

Please bring your diagnosis, recent autonomic and antibody test results, a full list of medicines and supplements, and any recent blood pressure readings. Tell us if you have a history of fainting or falls.

When to seek urgent medical care

Autonomic symptoms can signal a dangerous change in heart, blood pressure or nerve function and should be reported promptly to your treating physician.^[2]

• Fainting, or a fall with injury
• Chest pain, a racing or very slow heartbeat, or palpitations with light-headedness
• New weakness, trouble breathing, trouble swallowing or trouble speaking
• Severe vomiting or inability to keep fluids down
• Sudden confusion, seizures or severe headache
• Symptoms that are quickly getting worse

If any of these occur, call 911 or go to the nearest emergency department.
