SGB for Dysautonomia and POTS: How It Helps Reset The Autonomic Nervous System

Living with Dysautonomia or POTS can feel confusing and exhausting. Many patients describe a constant sense of being “stuck” in a fight or flight response, even when nothing stressful is happening. Stellate Ganglion Block, or SGB, is an image-guided injection that can help calm this overactive system. Although best known for its use in PTSD, it is becoming an emerging option for autonomic dysfunction, including Dysautonomia and POTS.

This guide walks you through how SGB works, why it may help, what the procedure is like, realistic expectations, safety, and how to know if it could be the right step for you.

What SGB Is and Why It May Help POTS and Dysautonomia

SGB is a precise injection that temporarily numbs the stellate ganglion, a bundle of nerves in the lower neck that helps regulate the sympathetic nervous system. By calming this “fight or flight” center, SGB may reduce symptoms like rapid heart rate changes, dizziness, temperature swings, flushing, sleep disruption, and sensory sensitivity.

Off-Label But Promising Approach

SGB is not FDA approved specifically for POTS or Dysautonomia. However, early case studies and clinical experiences from specialty clinics show encouraging improvements in autonomic stability. At IOW, the procedure was performed with careful screening and medical oversight.

What Patients Commonly Report

Patients often describe improvements such as:

• steadier heart rate responses

• fewer surges of adrenaline

• better sleep

• improved temperature control

• lower fatigue and fog over time

Results vary, but many people notice changes within hours to days.

What Is SGB for Dysautonomia and POTS?

How It Targets the Autonomic Nervous System

Your autonomic nervous system has two main branches: sympathetic and parasympathetic. The sympathetic system creates alertness and regulates heart rate, blood pressure, blood flow, digestion, and temperature control. Dysautonomia and POTS often involve excessive sympathetic activity.

SGB quiets this overactivity by temporarily blocking nerve signaling at the stellate ganglion. For some patients, this creates a reset effect, making the system less reactive and more balanced.

Why Image Guidance Matters

Safety and precision rely on real-time visualization. At Interventional Orthopedics of Washington, SGB is always performed under ultrasound guidance to ensure the anesthetic is placed exactly where it needs to be. This decreases risk and improves consistency of results.

Does SGB Help POTS Symptoms?

What Early Studies and Case Reports Show

Research is still developing, but several small studies and growing clinical case reports (reference Suarez M, Ibidunni L, Jevotovsky DS, Chopra H, Marascalchi BJ. Use of Stellate Ganglion Block in the Treatment of Postural Orthostatic Tachycardia Syndrome: A Novel Case Report. Pain Med Case Rep. 2025 Oct;9(6):329-333. PMID: 41135025.) & Lee M, Bartuska A, Chen J, et al Stellate ganglion block catheter for paroxysmal sympathetic hyperactivity: calming the ‘neuro-storm’Regional Anesthesia & Pain Medicine 2023; 48:522-525. Demonstrate meaningful symptom improvement for some patients. These benefits tend to relate to heart rate stability, reduced hyperadrenergic surges, decreased fatigue, and better quality of life.

It is important to note that SGB is not a cure and not everyone responds. It is best viewed as part of a broader treatment strategy.

How Long Results May Last

Many people experience relief for weeks to months. Some require follow-up or booster sessions if symptoms slowly return. Responses vary based on:

• severity of dysautonomia

• chronicity of symptoms

• baseline inflammation

• coexisting conditions

• stress or illness triggers

Your care team will look at your response to help guide next steps.

What To Expect During the SGB Procedure

Before Your Visit

Your visit begins with a medical review, symptom assessment, and discussion of your goals. Your provider will explain the procedure in detail and make sure there are no contraindications.

During The Procedure

You will lie comfortably on your back with your head slightly turned. After cleansing the area, a small amount of local anesthetic is used to numb the skin. Using ultrasound, the physician places the needle next to the stellate ganglion at the C6 or C7 level and injects local anesthetic around the nerve bundle.

Most Dysautonomia and POTS patients start with the right side. The left side may be treated either during a second session or later if needed.

The entire appointment usually lasts 45 to 60 minutes.

Aftercare and Recovery

Mild effects are normal shortly after the injection. These can include:

• warmth in the arm

• eye redness or tearing

• a droopy eyelid

• mild throat tightness with discomfort with swallowing

• temporary voice changes

These signs are expected and typically fade within hours. Most patients resume daily activities the same day, while strenuous activity may be delayed until cleared by the provider. You will also receive follow-up instructions and symptom tracking questionnaires.

Is SGB Safe for Dysautonomia and POTS?

Rare Complications

Although uncommon, potential complications include:

• bleeding

• infection

• vascular puncture

• nerve injury

• pneumothorax

• local anesthetic reaction

Choosing an experienced ultrasound-guided practitioner significantly reduces these risks.

How IOW Ensures Safety

At IOW, every SGB is performed with:

• live ultrasound guidance

• sterile technique

• real-time needle visualization

• safety checks before and after injection

• post-procedure monitoring

This approach emphasizes precision and patient comfort.

Who Is a Good Candidate for SGB?

Good Fit

SGB may be an appropriate option for patients who:

• have diagnosed or suspected Dysautonomia or POTS

• struggle with persistent symptoms despite lifestyle and medication strategies

• experience significant sympathetic overactivity

• want a non-pharmaceutical treatment option

• have been medically cleared and evaluated by a specialist

Not Ideal Fit

Patients with the following may not be eligible:

• active infections near the injection site

• bleeding disorders

• uncontrolled cardiovascular issues

• allergy to anesthetics

• certain neck or nerve conditions

A consultation is essential to confirm safety.

How SGB Compares to Other Dysautonomia Treatments

Works Alongside Lifestyle and Medication

SGB is not intended to replace foundational treatment. Instead, it often enhances the effectiveness of:

• salt and fluid strategies

• compression therapy

• physical conditioning

• beta blockers or other medications

Many patients find that when the autonomic system is calmer, these standard strategies become easier to tolerate.

Why It Is Different

Most Dysautonomia and POTS treatments address symptoms. SGB acts upstream at the level of the sympathetic nervous system, providing a physiologic reset that can improve overall system regulation.

IOW’s Approach and Why Technique Matters

Image-Guided Expertise

Interventional Orthopedics of Washington specializes in precision medicine and ultrasound-guided procedures. The team has extensive experience with targeted nerve injections, including SGB, and prioritizes accuracy and patient comfort.

Personalized Follow-Up Care

Your response is monitored over days to weeks with check-ins and symptom scales. For some, booster sessions or bilateral treatment are considered based on their progress.

What We Still Do Not Know

As with many emerging therapies, there is more to learn. Ongoing research continues to explore:

• which patients respond best

• how long benefits can last

• ideal treatment frequency

• long-term effects

• applications in long COVID, fatigue syndromes, and overlapping conditions

This transparency is important, because it helps set realistic expectations.
