Types & Causes

Neuropathy isn’t a single disease. It’s an umbrella term covering dozens of distinct conditions that all share one thing in common: damaged or dysfunctional peripheral nerves. The type you have — and its underlying cause — matters enormously, because it shapes everything from how your symptoms feel to which treatments are most likely to help.

When someone tells me they have neuropathy but aren’t sure why — or their doctor hasn’t given them a clear answer — this is where I send them first. Understanding your specific type isn’t just satisfying academically. It can genuinely change your treatment path.

The most common form is diabetic neuropathy, affecting roughly half of all people with diabetes over time. But there are many others:

• Neuropathy caused by chemotherapy
• Autoimmune attacks on nerve fibers
• Infections like shingles
• Nutritional deficiencies
• Medications — including some commonly prescribed statins
• Thyroid dysfunction
• Hereditary forms like Charcot-Marie-Tooth disease
• Idiopathic neuropathy — where no cause can be identified

If you’ve been told you have idiopathic neuropathy, that doesn’t mean you’ve hit a dead end. It means more investigation may be warranted. Some of the articles below dig into causes that are frequently missed.

Small fiber neuropathy deserves special mention because it’s frequently underdiagnosed — standard nerve conduction tests often come back normal even when something is clearly wrong. If you have burning pain, temperature sensitivity, and autonomic symptoms but your EMG was “fine,” please read that article.
