Why I Started Looking at Root Causes Instead of Just Symptoms — A Functional Medicine Perspective

I made a medical decision years ago that I can’t undo.

At the time I made the best choice I could with the information I had. But now — years later, deeper into functional medicine, with a completely different lens on how the body works — I find myself wondering. What if someone had looked deeper first? What if there was another option worth trying?

That question lives with me. And honestly it’s part of why I practice the way I do now.

The problem with treating the diagnosis instead of the person

Let me give you an example I see often — thyroid disease.

Two patients walk in. Both diagnosed with hypothyroidism. Both prescribed the same medication. Both told their levels are “normal” on follow up.

But they’re not the same patient.

One has an autoimmune condition silently attacking her thyroid. The other has nutrient deficiencies — low selenium, low zinc, low iodine — that are disrupting how her body produces and converts thyroid hormones. Another might have chronic stress driving inflammation that’s interfering with the entire process.

"Same diagnosis. Completely different root causes. Completely different solutions."

When we only check TSH and T4 we’re looking at the end result of a very complex process. We’re not asking why. And in medicine why is everything.

What root cause medicine actually looks at

Functional medicine starts with a simple but radical question — what is actually causing this?

For thyroid health alone that means looking at antibodies to rule out autoimmune disease, nutrient levels that support hormone production and conversion, inflammatory markers, toxic load, gut health, and stress hormones. It means looking at the whole person not just the lab value that’s out of range.

This isn’t anti-conventional medicine. I trained in internal medicine. I believe in evidence based care. But I also believe that conventional medicine is often designed to manage disease — not prevent it or reverse it.

Root cause medicine asks a different question from the start.

What this means for my patients

At KIWI MED every patient gets a deeper look. Not just what’s wrong but why it’s happening and what we can actually do about it — through nutrition, lifestyle, advanced testing, and when appropriate, targeted treatment.

Just because two people share a diagnosis doesn’t mean they share a solution.

You deserve care that sees you as an individual. Not just a set of lab values.
