The Gut’s Nerve Network: Enteric & Autonomic Neuropathies

Enteric & Autonomic Neuropathies Made Simple (El Paso Patient Guide)

---

Key takeaways

• Your gut has its own nerve system (the enteric nervous system, ENS) that works with your body’s autonomic nerves to move food, absorb nutrients, and keep everything coordinated.

• When these nerves are damaged—called enteric neuropathy or autonomic neuropathy—people can develop gastroparesis (slow stomach), constipation, diarrhea, bloating, and nausea (Stanford Health Care, n.d.; NIDDK, 2018/2025).

• Diabetes is the most common cause worldwide, but autoimmune, infectious, nutritional, toxic, and medication-related factors also play important roles (Azpiroz & Malagelada, 2016; Carlotta et al., 2018; Camilleri, 2021).

• Effective care pairs cause-directed treatment (e.g., blood-sugar control, correcting deficiencies) with symptom relief and functional rehab.

• Chiropractic integrative care at Dr. Jimenez’s clinic supports medical plans by improving posture, rib and spinal motion, breathing mechanics, soft-tissue balance, and strength—helping you move, recover, and manage daily life more comfortably.

What are enteric and autonomic neuropathies?

Your enteric nervous system (ENS) sits inside your digestive tract and contains millions of neurons and supportive glial cells. It runs “on autopilot,” coordinating muscle contractions, enzyme release, and blood flow. The autonomic nervous system (ANS) connects your brain and spinal cord to the gut and other organs to manage “automatic” functions like heart rate, blood pressure, and sweating.

When these nerves are impaired, the gut’s timing and coordination break down. Common results include slow emptying of the stomach, irregular small-bowel movement, constipation or diarrhea, and bloating (Stanford Health Care, n.d.; NIDDK, 2018/2025; Camilleri, 2021). Research shows that enteric glia help protect the intestinal lining and signal with neurons; inflammation or immune triggers can change how these cells behave, shifting motility and sensitivity (Patankar et al., 2025; Vicentini et al., 2022).

How these problems show up day to day

• Gastroparesis (slow stomach): Early fullness, nausea, vomiting of undigested food, loss of appetite, and weight changes (Stanford Health Care, n.d.; Azpiroz & Malagelada, 2016).

• Small-bowel dysmotility: Bloating, distension, pain, and sometimes small intestinal bacterial overgrowth (SIBO) with gas and diarrhea (Camilleri, 2021; “Small intestine dysfunction…,” 2024).

• Colon/rectum dysmotility: Constipation, diarrhea, or alternating patterns; urgency or accidents if rectal sensation/coordination are affected (NIDDK, 2018/2025).

• Whole-body autonomic clues: Lightheadedness on standing, sweating changes, or heart-rate swings may travel with GI symptoms (NIDDK, 2018/2025).

Symptoms can fluctuate. Many people report worse bloating after bigger meals, during stress, or when they are inactive (Camilleri, 2021).

Why it happens: major causes

Diabetes (most common)

Long-term high blood glucose damages small blood vessels and nerves serving the gut, disturbing gastric and intestinal motility (Azpiroz & Malagelada, 2016; NIDDK, 2018/2025). Better glucose control helps prevent progression and may ease symptoms (NIDDK, 2018/2025).

Autoimmune & inflammatory drivers

Immune reactions can target nerve receptors, ion channels, or other components of enteric/autonomic pathways, changing reflexes and motility (Camilleri, 2021). Emerging data also tie small-fiber neuropathy and barrier dysfunction to GI symptoms in some patients (Massachusetts General Hospital—Pathways, 2022).

Infections and post-infectious changes

Some viral or bacterial infections temporarily (or sometimes persistently) change ENS signaling and motility. Immune activity can alter glia-neuron communication and tight-junction integrity, affecting transit and sensitivity (Massachusetts General Hospital—Pathways, 2022).

Nutritional deficits & malabsorption

Deficiencies in vitamin B12, vitamin E, and other nutrients can injure nerves. Malabsorption disorders also carry neurological risks (Carlotta et al., 2018).

Toxins, medications, and chemotherapy

Certain drugs and toxic exposures can injure autonomic and peripheral nerves, producing both limb symptoms and new bowel patterns (Piedmont Healthcare, n.d.; Camilleri, 2021).

How clinicians make the diagnosis

1. History & exam: Map GI symptoms, meals, hydration, weight change, glucose control, medications, and red flags (NIDDK, 2018/2025).

2. Lab tests: A1c/glucose; thyroid; B12, folate, vitamin E; iron studies; inflammatory and autoimmune markers as indicated (Carlotta et al., 2018).

3. Motility & autonomic testing:

   • Gastric emptying study (or breath test) for suspected gastroparesis (Azpiroz & Malagelada, 2016).

   • Manometry or wireless motility capsule for small bowel/colon (Camilleri, 2021).

   • Autonomic testing in broader dysautonomia (NIDDK, 2018/2025).

4. Imaging & specialized studies: Abdominal imaging as needed; in complex cases, evaluation of barrier function or small-fiber neuropathy may be considered (Massachusetts General Hospital—Pathways, 2022).

Treatment strategy: fix the driver + calm the symptoms + rebuild function

A) Address the cause

• Diabetes care: Tight glucose control; coordinate meds and nutrition (NIDDK, 2018/2025).

• Autoimmune/inflammatory: Tailored therapy by specialists (Camilleri, 2021).

• Deficiencies: Replete B12, vitamin E, and other nutrients (Carlotta et al., 2018).

• Post-infectious/SIBO: Treat appropriately and monitor responses (Camilleri, 2021).

B) Relieve symptoms

• Gastroparesis: Small, more frequent meals; softer textures; more liquids; low-fat/low-fiber during flares; prokinetic and anti-nausea medications as appropriate (Stanford Health Care, n.d.; Azpiroz & Malagelada, 2016).

• Constipation: Fluids; fiber as tolerated; osmotic laxatives; short-term stimulant agents; pelvic-floor rehab if outlet dysfunction (NIDDK, 2018/2025).

• Diarrhea: Hydration/electrolytes; antidiarrheals when appropriate; evaluate for malabsorption/SIBO (Camilleri, 2021).

• Bloating/pain: Trigger review, gentle activity, breathing drills, and targeted meds per clinician (Camilleri, 2021).

C) Rebuild function with daily habits

• 5–10 minutes of easy walking after meals to promote gas transit and comfort (Camilleri, 2021).

• Meal pacing: smaller portions, chew well, sip fluids through the day.

• Breathing practice: quiet nasal, low-tension diaphragmatic breathing to reduce abdominal wall guarding and stress reactivity.

• Sleep and stress routines to steady autonomic tone.

Where chiropractic integrative care fits at Dr. Jimenez’s clinic

Important: Chiropractic integrative care does not claim to cure enteric/autonomic neuropathy. It supports your medical plan so you can move, eat, and rest with less strain. At Dr. Jimenez’s El Paso clinic, the team blends chiropractic care with nurse practitioner medical evaluation to address the musculoskeletal and nervous-system foundations that influence comfort and function.

What this looks like:

• Spinal and rib mobilization/manipulation (as appropriate) to restore motion that supports breathing mechanics and reduces abdominal wall tension.

• Soft-tissue therapy for paraspinals, diaphragm attachments, hip flexors, and abdominal wall to decrease pressure and guarding.

• Rehabilitation exercises: posture practice, gentle core endurance, hip stability, and graded walking so you can tolerate meals and daily tasks better.

• Breathing re-training to lower sympathetic (stress) drive that can aggravate gut symptoms.

• Education & pacing to prevent over-exertion and flare-ups while building strength.

How dual-scope care helps:

• The APRN (FNP-BC) side coordinates labs, imaging, and referrals (e.g., neurogastroenterology, motility testing) and co-manages medications with your primary team.

• The DC side evaluates biomechanics, mobility limits, and soft-tissue patterns, then sequences safe progressions.

• When appropriate, the clinic uses advanced neuromusculoskeletal imaging (X-ray, ultrasound, MRI) to clarify pain generators, tailor loading, and document objective changes over time—useful both clinically and, when needed, for work, sports, personal, and MVA documentation.

A typical care pathway in our clinic (example)

1. Intake & screening: We chart GI symptoms, diet, hydration, glucose metrics, sleep, stress, and daily activity. We also screen for urgent signs (e.g., persistent vomiting, rapid weight loss, GI bleeding).

2. Testing & referrals: Based on findings, we coordinate bloodwork, imaging, or GI motility studies, and we communicate results clearly with you and your other clinicians.

3. Integrated plan:

   • Medical steps (e.g., glucose optimization, nutrient repletion, SIBO treatment).

   • Chiropractic steps (mobility + soft-tissue + breathing + graded activity).

   • Nutrition and pacing strategies customized to your tolerance.

4. Progress tracking: We track outcomes you can feel (meal tolerance, bloating ratings, step counts, sleep) and objective markers (strength, range, and imaging as indicated). Plans adjust as your capacity grows.

What you can start doing this week

• Shrink meal size and increase frequency; blend or soften foods during flares.

• Sip fluids all day; add electrolytes during diarrhea bouts.

• Walk 5–10 minutes after meals; keep the pace relaxed.

• Practice 5 minutes of slow nasal breathing twice daily.

• Ask about labs: A1c; B12; vitamin E; thyroid; iron studies—if not checked recently.

• Keep a simple log of meals, symptoms, movement, and sleep to help your care team map patterns.

---

When to call your clinician urgently

• Persistent vomiting, signs of dehydration, or inability to keep liquids down

• Black or bloody stools, severe abdominal pain, or unexplained rapid weight loss

• Severe dizziness or fainting on standing (possible serious autonomic involvement)

(Stanford Health Care, n.d.; NIDDK, 2018/2025)

The bottom line

Enteric and autonomic neuropathies are real, common, and manageable. Most patients do best with a combined plan: treat the cause, calm the symptoms, and rebuild function step by step. At Dr. Alex Jimenez’s El Paso clinic, dual-scope care (APRN + DC) and advanced imaging support a practical, patient-centered path forward—so you can eat, move, work, and rest with greater confidence.
