Health Conditions
A diagnosis names the pattern. It does not explain how you got here.
Seventeen guides to the conditions people actually arrive with, written to explain the physiology underneath the label. Understand the pattern first. Investigate it second.

What sits under a label
The diagnosis
Names the pattern
What sits underneath it
Pattern, physiology, timeline.
A diagnosis is a useful thing. It gives a name to a pattern, connects you to other people who have it, and points toward treatments that have been studied. What it does not always do is explain how the pattern developed in you, why it appeared when it did, or which parts of your physiology are keeping it going.
Two people can carry the same label and arrive there by completely different routes.
These guides are about the route.
The idea behind every page here
A diagnosis names the pattern. It does not always explain how the pattern developed.
Beyond the label
What a careful evaluation actually considers.
Symptoms and diagnoses are the starting point of an evaluation rather than the end of it. Once the pattern has a name, the useful questions are about what produced it and what is still feeding it. That means looking at physiology, at the order events happened in, and at the systems that sit underneath the presenting complaint.

None of that replaces a diagnosis. It explains what is holding it in place.
How this library works
From a symptom to a decision.
These pages and the testing pages answer different halves of the same question. A condition page helps you understand the pattern you are living with and which systems are involved. A testing page explains how that pattern is investigated and what a given laboratory result can and cannot say. Read across both and the sequence becomes clear.
Condition pages
Testing pages
The two libraries overlap in the middle, which is where most of the useful thinking happens.
Condition pages help you understand the pattern. Testing pages explain how we investigate it.
If you are not sure where to begin
Start from what you actually notice.
Most people do not arrive with a system in mind. They arrive with a sentence. Find the one closest to yours and begin there. None of this is a diagnostic tool and none of it replaces an evaluation. It is a way into the right reading.
“I feel tired all the time.”
Begin with Chronic Fatigue and Pain, then Thyroid and Nutrients.
“I have an autoimmune diagnosis.”
Begin with Autoimmune, then Gut Health and Chronic Inflammation.
“My labs are normal, but I do not feel well.”
Begin with Comprehensive Blood Chemistry, then Nutrients.
“I am preparing for pregnancy.”
Begin with Fertility and Maternal Health, then Nutrients.
“I want to understand my cardiovascular risk.”
Begin with Heart and Cardiometabolic Health, then Blood Sugar and Metabolic Health.
“I want to stay well rather than treat something.”
Begin with Longevity and Wellness, then Functional Medicine Testing.
These are reading paths, not diagnoses. Symptoms overlap across every system on this page, which is exactly why the evaluation matters more than the starting guess.
The library
Seventeen guides, grouped by system.
Each guide explains what the system does when it is working, what it looks like when it drifts, which patterns point where, and how the question gets investigated. They are written to be read on their own, and they link to each other where the physiology genuinely overlaps.
Digestion and metabolism
Gut Health
What healthy digestion actually requires, where the sequence breaks down, and how symptoms point toward the failure point rather than the diagnosis.

Blood Sugar and Metabolic Health
How glucose and insulin regulation drifts quietly, often for years, before a fasting result ever moves out of range.
Read the guide →
Nutrients and Optimal Supplementation
What the body needs, what it can actually absorb, and why taking more is not the same as having enough.
Read the guide →
Hormones, fertility and development
Thyroid
Signalling, conversion and autoimmunity are three very different stories told by one small gland.
Read the guide →
Hormone Health
How the body communicates and adapts, read in context rather than as a set of isolated numbers on a page.
Read the guide →
Fertility and Maternal Health
Preparing the physiology a pregnancy will depend on, before it is asked to depend on it.
Read the guide →
Childhood Development
The foundations laid early, what supports them, and which changes deserve attention rather than waiting.
Read the guide →
Immune and inflammatory
Autoimmune
Why immune tolerance changes, what the immune system may be responding to, and what that means for the plan.
Read the guide →
Chronic Inflammation
The low-grade smoulder that sits underneath a great deal of chronic disease, and how it is actually measured.
Read the guide →
Chronic Infections
When an organism genuinely belongs in the clinical story, and the more common situation where it does not.
Read the guide →
Respiratory and Sinus Health
Airways and barriers, and the environment they spend every day negotiating with.
Read the guide →
Brain, mood and energy
Brain Health, Mood and Neuroinflammation
How the brain is affected by nearly everything happening below it, and why mood is a physiological reading too.
Read the guide →
Headaches and Migraines
Patterns, triggers and the physiology behind them, rather than a longer list of things to avoid.
Read the guide →
Chronic Fatigue and Pain
What happens when energy production and pain signalling stop behaving, and how that is separated from everything else that causes tiredness.
Read the guide →
Heart, movement and longevity
Heart and Cardiometabolic Health
Particle-level risk and the metabolism sitting underneath it, not just a total cholesterol number.
Read the guide →
Joint and Muscle Health
Structure, load and the inflammation that changes how both of them behave over time.
Read the guide →
Longevity and Wellness
What keeps function intact as the years accumulate, which is a different question from what treats disease.

Get the Testing Roadmap
A short guide to how a functional medicine physician decides what to test, and in what order, so you can ask better questions about your own health. Educational, not a diagnosis.
Own your biology
The label is the beginning of the question.
A diagnosis earns its place. It organises what is known, connects you to real evidence, and often points to treatment that helps. What it cannot do on its own is tell you which parts of your physiology carried you there, or which of them are still carrying you.
That is the work these guides are for. Not to replace the diagnosis, and not to promise that every symptom traces to one hidden cause, but to explain the systems underneath well enough that you can ask better questions about your own body.
What is the patternWhich systems are involvedWhat changed, and whenWhat is still feeding itWhat would testing actually settleWhat changes the next decision
Read the guide that matches what you are living with. Then read how the question gets investigated. The two together are worth far more than either one alone.
Bring the pattern, not just the label.
No pressure, and nothing to buy. Come with what you have been told, what you have noticed, when it started and what has already been tried, and we can work out together which system to look at first.
