Why Neuropathy Doesn't Have to Be a Life Sentence: Inside the Conversation With Dr. Mo Karim

Released on the site as "A Conversation with Dr. Mo Karim," this episode turned into something more specific: a plain-language breakdown of why chronic nerve pain isn't automatically a life sentence, even for patients who've been told exactly that. Dr. Mo Karim, DC, of Iowa Wellness Center joined host Mark Anthony — the two have known each other for years — to walk through what's actually happening inside a nerve when neuropathy sets in, and why he believes so many patients end up stuck on medication instead of getting at the underlying cause.

Karim is board certified in chronic intractable pain and neuropathy through the American College of Physical Medicine, and in functional neurology through the American Functional Neurology Institute. In the conversation, he was direct that his patients are often people who've already been told by other doctors that neuropathy "can't be healed" — and that he disagrees with that framing.

Why Neuropathy Doesn't Have to Be a Life Sentence, According to Dr. Karim

Karim said the "you'll just have to live with it" message is what he hears from new patients constantly — and that it's often wrong. He noted that neuropathy doesn't only show up as pain; some patients arrive with numbness, tingling, or unusual cold or hot sensations in the hands and feet and no pain at all. His starting point is that nerves are living cells, the same as any other tissue that heals when it gets what it needs. "Nerves are cells," he said. "If you get a cut and it heals, that's the same thing — you cut your muscle, you cut your skin, that heals. Those are cells that start to heal. Well, that's the same thing with the nerves." He added that nerves are more complex, but the basic requirement is the same: oxygen and nutrients delivered through circulation.

To explain why that circulation fails, Karim used a plant analogy — thick roots feed thinner roots, which feed microscopic root hairs, and when the smallest hairs die off, the next size up follows, then the next. He described the same pattern with blood vessels: the micro vessels that directly feed the nerves are the first to lose supply, and larger vessels degrade after them. He also described nerves as having a normal firing rate — he put it at around 270 miles an hour — that can drop to well below 50 miles an hour once circulation to the area declines, which is part of why the brain stops registering the area as active and reduces blood flow to it further. He tied this to the myelin sheath, the coating around a nerve fiber, which he said thins as the nerve's signal weakens, and framed treatment as rebuilding the micro-vessel network and re-coating that sheath so the nerve can fire normally again.

The Three Components Behind Chronic Nerve Pain

Karim's framework for treating neuropathy centers on three components he says have to be addressed simultaneously, or symptoms come back: the nerves themselves (the actual symptoms — burning, numbness, tingling), circulation (specifically the micro blood vessels, not the larger vessels doctors typically check), and metabolic health, which for him centers on gut-driven inflammation. He described the gut as "your second brain" and the source of a large share of chronic disease and inflammation in his patients, listing diabetes, Crohn's disease, ulcerative colitis, fibromyalgia, restless leg syndrome, and thyroid problems as conditions he sees tied back to it. Inflammation, he said, tends to target the joints first — back, neck, shoulder, and elbow pain — before moving to the nerves as burning, numbness, and tingling.

He was emphatic that treating only one or two of the three components doesn't work. "If we're not addressing all three, it's never going to heal," he said. "If I'm just doing the nerve and the circulation and not doing the metabolic, then we're never going to get rid of that inflammation — so it's going to come back."

Inside a Neuropathy Evaluation at Iowa Wellness Center

Karim walked through his evaluation process in some detail. New patients go through a full history and consultation, then a hands-on exam that he said takes about an hour — no diagnostic machine, just direct sensory testing. He checks sharp sensation, light touch, cold, heat, and vibration in the hands and feet to map how much sensory loss a patient has in each limb, and in more severe cases, he said patients sometimes can't identify which toe or finger is being touched without looking. He also runs tests aimed at the brain side of the equation — checking whether one side of the brain is registering signals differently than the other. Because of how much data the exam generates, he has patients return for a second visit, once he's had time to put the findings together into what he described as a customized plan specific to that patient — including whether the clinic is even a fit for their case.

Rethinking Medication — and Who This Conversation Is For

Karim was candid about his view of long-term medication use for neuropathy. He noted that over-the-counter medications are generally labeled not to exceed about 15 days of continuous use, and that going beyond that window is where the body starts building tolerance — doses get increased, new symptoms appear, and new medications get layered on to mask them. He said it's common for new patients to arrive on 20 or more prescriptions, often unable to say why they're taking each one. Where appropriate, he described weaning patients off certain medications over roughly three months, always with the instruction to follow up with their own medical doctor for blood work and to review dosages — and he was clear that medications for conditions like diabetes or heart disease aren't something patients should stop on their own. He also said he has reversed type 2 diabetes in a number of patients primarily through diet changes, monitored through the patients' own blood glucose testing.

If you've been told a chronic nerve issue is simply something to manage for life — or you're weighing whether long-term medication is really solving the underlying problem — this conversation is a useful, plain-language look at how one practitioner thinks about circulation, inflammation, and the nervous system together.
