Peripheral Neuropathy: Why Your Toes Are the First to Feel It

If your symptoms started in your toes, that isn't random. The nerve fibers that reach your big toe are among the longest cells in your body, running roughly three feet from beside your spine to the tip of your toe, and almost everything the far end needs, including mitochondria, has to be shipped down that line. In this video, Dr. Fitz explains how that long supply line fits the typical toes-to-shins-to-fingertips pattern, why small fibers are often affected first, why a standard nerve conduction test can come back normal, and why the whole metabolic picture matters, not just blood sugar. He also covers what the research says about exercise and supplements, and where the evidence is still limited.

What you'll learn in this video

  • Why the nerve fibers to your toes have the longest energy supply line in your body
  • The typical length pattern: toes, then shins, then fingertips, and why fingertips often join in around the time leg symptoms reach the knee
  • Which symptom patterns don't fit the length pattern and deserve their own evaluation
  • Large vs. small nerve fibers, and why small fibers are usually affected first
  • Why a standard nerve conduction test can be normal when small fibers aren't, and which tests look at them
  • How insulin resistance, triglycerides, and HDL load the same system, even before diabetes
  • What a small University of Utah exercise study found, and its honest limits
  • What the research does and doesn't show for alpha-lipoic acid and "mitochondrial" supplements
