Autonomic Neuropathy

When nerve damage reaches the systems on autopilot.

Autonomic neuropathy is damage to the nerves that run your automatic functions — digestion, blood pressure, heart rate, sweating, and bladder control. It often travels alongside peripheral neuropathy in the feet and hands, and it deserves careful, coordinated care.

Understanding Autonomic Neuropathy

What It Is & Why It Happens

Most people think of neuropathy as a feet-and-hands problem. But the same processes that damage the long sensory nerves can also affect the autonomic nervous system — the network that quietly runs everything you don't think about. When those fibers struggle, the symptoms are strange and easy to misattribute: feeling dizzy or lightheaded when you stand, food sitting heavy long after meals, sweating too much or hardly at all, a heart rate that doesn't respond the way it used to.

Autonomic involvement matters for two reasons. First, some of its symptoms — especially blood-pressure drops, fainting, and heart-rate changes — need proper medical evaluation to rule out conditions that require direct medical management. We take a physician-first posture here: if your history suggests anything that needs a cardiologist, gastroenterologist, or your primary doctor's attention, that referral comes before anything else. Second, autonomic symptoms often ride along with the burning and numbness of peripheral neuropathy, because the same underlying drivers — blood-sugar problems, inflammation, poor circulation — affect both systems.

Our role is supporting overall nervous-system health alongside your medical team: objective testing to understand how your nerves are functioning, care that targets circulation, inflammation, and structural stress on the nervous system, and honest coordination with the physicians managing the medical side. Autonomic neuropathy is a team sport, and we're comfortable saying so.

Common Symptoms

Signs You May Be Dealing With Autonomic Neuropathy

  • Dizziness or lightheadedness when standing up
  • Digestive trouble — early fullness, bloating, food that 'just sits'
  • Sweating changes — too much, too little, or in unusual patterns
  • A heart rate that stays high at rest or doesn't adjust with activity
  • Bladder changes — urgency, hesitancy, or incomplete emptying
  • Heat intolerance or trouble regulating body temperature
  • Often paired with numbness, tingling, or burning in the feet

How We Help

Our Treatment Approach

Dr. Logan Swaim, MS, DC has spent years specializing in peripheral neuropathy. Every program begins with a comprehensive nerve function assessment before any treatment is recommended.

  • Careful history and screening first — symptoms that need direct medical evaluation get referred before any care is recommended
  • Comprehensive nerve function assessment: sensory exam, circulation assessment, and balance testing to map how the wider nervous system is doing
  • Care focused on the shared drivers — circulation, inflammatory load, and structural stress on the nervous system
  • Red light therapy where circulation support is indicated by your evaluation
  • Nutritional guidance for the deficiencies that commonly accompany autonomic dysfunction
  • Ongoing coordination with your primary doctor and specialists — we share findings and progress with your permission

Common Questions

Frequently Asked Questions

Some of its symptoms deserve real medical attention — especially fainting, significant blood-pressure drops on standing, or heart-rate abnormalities. Those need evaluation by your physician or a cardiologist first, and we'll tell you that plainly at your consultation. Many other autonomic symptoms are quality-of-life problems that respond to addressing the underlying drivers. The honest answer starts with a careful history.
Diabetes is the most common cause — long-term blood-sugar elevation affects the autonomic fibers just as it affects the sensory ones. Other contributors include autoimmune conditions, certain infections, and in some cases no identifiable cause. Because the drivers overlap with peripheral neuropathy, many people have both at once.
Autonomic fibers respond to the same fundamentals other nerves do: better circulation, lower inflammatory load, and management of the underlying cause. How much improvement is realistic depends on how long the damage has been present and what's driving it — which is why we measure first and speak honestly about what your evaluation shows.
We support nervous-system health as a whole — circulation, inflammation, structure, and nutrition — alongside whatever medical management your physicians have in place. We are not a replacement for cardiology, gastroenterology, or your primary doctor, and we coordinate with them gladly. Think of our program as working on the environment your nerves live in while your medical team manages the medical side.
Physicians use tests like tilt-table testing, heart-rate variability studies, and gastric-emptying studies depending on the symptoms. At our clinic, the evaluation focuses on the functional picture: your history, sensory and circulation testing, and balance — plus flagging anything in your story that warrants specialist workup before care begins.
