Gut-Brain Medicine
Your gut is talking to your brain, your immune system, and your thyroid. When it's off, everything is off.
Microbiome Restoration for Mood, Immunity, and Metabolism
Opening
Sequencing did for the microbiome what the microscope did for cell biology.
In the last ten years, sequencing technology has done for the microbiome what the microscope did for cell biology. We can now read the entire genetic content of what lives in your gut, and what we've found has rewritten large parts of medicine.
Your gut produces most of your body's serotonin, and your gut bacteria shape how much. They talk to your brain through the vagus nerve and through chemical messengers. They train your immune system and decide how it responds to the outside world. They control what you can absorb from what you eat. They manufacture vitamins you can't make yourself. And when the balance is off, the consequences show up far from the gut: in your mood, your energy, your skin, your joints, your thyroid, your weight, and your brain.
Most people with a gut problem don't know they have one, because it doesn't feel like a gut problem. It feels like anxiety. Or fatigue. Or autoimmune disease. Or brain fog. Or a thyroid that won't stabilize no matter what dose you're on.
The connections most doctors don't make
Five links that change the plan.
Gut and brain
The gut has its own nervous system with more neurons than your spinal cord, and it communicates constantly with your brain. Inflammation in the gut becomes inflammation in the brain. That's why mood disorders, anxiety, and cognitive decline are increasingly understood as having a gut component, and why addressing the gut often improves them.
Gut and immune system
About 70 percent of your immune tissue lives in your gut wall. That tissue learns from your microbiome what to attack and what to tolerate. When the microbiome is disrupted, the immune system loses that calibration. That's the mechanism behind a large share of autoimmune conditions, and it's why gut restoration is central to how I approach them.
Gut and thyroid
Your gut converts a meaningful share of inactive thyroid hormone into its active form. Gut inflammation impairs that conversion. It also drives the immune dysregulation behind Hashimoto's, the most common cause of hypothyroidism. If your thyroid won't stabilize, I look at your gut.
Gut and nutrients
You are not what you eat. You are what you absorb. A damaged gut lining and a disrupted microbiome mean nutrients pass through without being taken up. You can eat perfectly and still be deficient. This is why I often see people on excellent diets with low B12, low iron, low vitamin D, and no idea why.
Gut and metabolism
The bacteria in your gut influence how many calories you extract from food, how your body handles blood sugar, and how much inflammation you carry. Two people can eat the identical meal and one stores it while the other burns it. Part of that difference lives in the microbiome.
What I test
Everything living in your gut, not a short list.
Comprehensive stool analysis using whole-genome sequencing, which reads everything living in your gut rather than the handful of species older tests could detect. It shows me your bacterial diversity, whether the keystone species that keep the system stable are present, whether pathogens or overgrowth are crowding them out, how well your gut is producing the short-chain fatty acids that feed your gut lining and calm inflammation, and whether your gut barrier is intact.
Where indicated, I add markers of intestinal inflammation, digestive function, and gut permeability, along with a micronutrient assessment to see what you're actually absorbing.
What restoration looks like
Not a probiotic and a prayer.
It's a sequenced approach: remove what's causing harm, restore the species that should be there, repair the gut lining, and rebalance the immune response. It's built from your specific results. What I do for someone with bacterial overgrowth is different from what I do for someone with low diversity, and both are different from someone with a compromised barrier.
It takes three to six months. The changes are durable when they're done properly.

FAQ
Questions I get asked most.
I don't have digestive symptoms. Could my gut still be the problem?
Yes, and this is common. Gut dysfunction often shows up first as fatigue, anxiety, skin issues, joint pain, or thyroid problems, not as bloating or bowel changes. If you have a persistent problem that hasn't responded to the obvious treatment, the gut is worth checking.
I already take a probiotic. Isn't that enough?
Usually not. A probiotic adds a few species without knowing what's missing or what's overgrown. It's like adding random plants to a garden without looking at the soil. Testing shows me the actual state of your microbiome, and restoration is built from that.
How is this different from the gut tests I can buy online?
The test I use is whole-genome sequencing, which reads the complete genetic content of your microbiome. Many consumer tests use older methods that see far less. And the test is only half of it. The other half is a physician reading it, connecting it to your symptoms and your other labs, and building a protocol. That's not something a consumer test provides.
Can gut restoration help with autoimmune disease?
The immune system learns from the gut what to attack and what to tolerate. Restoring gut health is a central part of how I approach autoimmune conditions, alongside conventional treatment where it's needed. I don't promise remission. I can tell you that addressing the gut is often the piece that's been missing.
How do I get started?
Book a free consultation. Tell me what you're dealing with and what you've already tried. I'll tell you honestly whether I think the gut is where to look, and what testing would actually answer the question.
