Is Arthritis Really Just Wear and Tear? The Gut, Hormone, and Diet Connection Your Doctor Misses

Cole Siefer (co-founder, host), Colin Renaud, DC, PA-C (Med Matrix provider)69:32Pain & RecoveryFebruary 18, 2026

Episode Summary

Colin Renaud (DC, PA-C) challenges the conventional "wear and tear" explanation for arthritis, arguing that arthritis is primarily an immune-mediated and inflammatory condition rather than a mechanical one. The episode covers the gut-joint axis, the role of hormonal decline in joint vulnerability, hidden infections like Lyme disease as contributors to joint pain, and how dietary choices perpetuate the inflammatory cycle that drives arthritic conditions. The conversation contrasts the conventional approach of anti-inflammatory medications and surgery with the functional medicine approach of identifying and turning off the root causes of inflammation.

Key Topics

  1. 1

    Why "wear and tear" is a misleading explanation for arthritis

  2. 2

    The gut-joint axis: how gut dysbiosis and leaky gut drive systemic inflammation and joint pain

  3. 3

    Hidden infections (Lyme disease) as a cause of migratory joint pain

  4. 4

    How sex hormones protect joints and why hormonal decline worsens arthritis

  5. 5

    The self-perpetuating inflammation cycle and why NSAIDs don't break it

  6. 6

    Nightshade vegetables and other dietary triggers of joint inflammation

  7. 7

    Nutritional deficiencies (omega-3s, zinc, magnesium, vitamin D) that prevent the body from turning off inflammation

  8. 8

    Peptides for inflammation reduction and soft tissue repair

  9. 9

    BPC-157: oral vs. injectable, when it works and when it won't

  10. 10

    Fibromyalgia and polymyalgia rheumatica as diagnoses that may reflect unaddressed root causes

Quotable Moments

Arthritis is not caused by wear and tear. People have arthritis in their hands and they're not Olympic runners. This whole wear and tear notion is just not the way arthritis works. Arthritis is really an immune-mediated issue.

The problem isn't necessarily just inflammation. It's a failure for the inflammation to turn off. You have dysfunction in your body that's driving inflammation, but then you also are deficient in things that is not bringing your inflammation down.

How many primary care doctors are talking to their patients about how their diet could be influencing their hip or back pain? Very little.

Colin Renaud, DC, PA-C

We have adapted in this country this sense that the body is just so unresilient and just this sack of deteriorating thing. We might be living longer, but people are living longer sicker. That's the sad part.

Colin Renaud, DC, PA-C

Pain is not normal. Pain is not a natural thing. If you live in pain and you're suffering or you can't work or you can't mobilize, do not accept that as a norm. That's not natural. It's not normal. It's not optimal.

Pain & Recovery FAQ

No. Arthritis is primarily immune-mediated and inflammatory. People develop arthritis in their hands without ever being athletes. The real drivers include gut dysbiosis, systemic inflammation, hormonal decline, and impaired tissue repair.

Leaky gut allows bacteria to enter the bloodstream, triggering immune responses that drive systemic inflammation and joint damage. Specific bacteria are linked to specific conditions: Prevotella copri with rheumatoid arthritis, Klebsiella with ankylosing spondylitis.

Yes. Testosterone reduces inflammatory signaling. When low, pain receptors that would normally be dampened become activated. Multiple patients with chronic pain became nearly pain-free within weeks of starting testosterone replacement therapy.

Chronic NSAID use damages the gut lining and liver. The NSAID temporarily suppresses pain but does nothing to address the inflammation source. The gut damage can actually worsen the intestinal permeability driving systemic inflammation.

Nightshade vegetables (tomatoes, eggplants, peppers), modern gluten, sugar, processed foods, seed oils, and dairy are all pro-inflammatory. Many patients eat these daily while relying on pain medication, creating a cycle that never resolves.

Yes, when root causes are addressed. This includes correcting nutritional deficiencies (omega-3s, zinc, magnesium, vitamin D), optimizing hormones, healing the gut, and eliminating inflammatory foods. Patients told they needed joint replacement have avoided surgery through functional medicine.
