A symptom is a moment. A pattern is a message. And most of us have been trained to only pay attention to the first one.

Here's what that looks like in practice: someone comes in with fatigue. On its own, fatigue tells us almost nothing, everyone is tired sometimes. But fatigue that's worse in the afternoon, paired with sugar cravings around 3pm, paired with waking up at 2am most nights? That's not three random complaints. That's a pattern, and patterns point somewhere specific. They might point to blood sugar swings, an adrenal/cortisol rhythm issue, or something else entirely, but you don't find out by treating fatigue in isolation. You find out by asking what it's connected to.

This is the whole premise of functional medicine, and it's what we'll be unpacking all month: not "what symptoms do you have," but "what's the pattern underneath it."

If you've been collecting a list of symptoms that never quite added up to a diagnosis, that list is more useful than you think. Bring it to your next visit, or start one with us. Virtual intakes are open; link in comments. 🌿

Fasting glucose is the test most people get, and it's the last thing to change. Earlier in the process, the pancreas compensates by producing more insulin, which holds glucose in a normal range — so glucose looks fine while insulin is quietly climbing.

By the time fasting glucose is abnormal, the process has been running for a long time. Markers that reveal it earlier: fasting insulin, HOMA-IR (calculated from fasting insulin and glucose), the triglyceride-to-HDL ratio, and hemoglobin A1c, which is read as a trend rather than a single value.

Why this belongs on an autoimmune account: insulin resistance and chronic inflammation are bidirectionally linked, and blood sugar instability is one of the more consistently reported flare inputs our patients identify. One note on the CGM trend — continuous monitors give genuinely useful feedback about your individual responses, but a glucose rise after a meal is normal physiology, not a crisis, and watching the number all day produces anxiety more often than insight. Ask your physician for a fasting insulin. It's inexpensive and rarely ordered.

When people think of food reactions, they think bloating, cramping, and urgency. Those are real, but they're the obvious ones.

The less obvious presentations, and the reason connections get missed for years, include migraines, joint pain, skin changes like eczema and unexplained rashes, brain fog, mood changes, chronic congestion, and fatigue that shows up a few hours after eating rather than immediately. That delay is a big part of the problem.

A reaction 24 to 48 hours after exposure is nearly impossible to spot without structured tracking. Now the caveat: because this is a corner of our field with real quality problems: IgG food sensitivity panels are widely sold, and their diagnostic validity is not established — several major allergy organizations recommend against them. A carefully structured elimination and reintroduction, with symptoms tracked in writing, remains more informative than most panels you can buy, and costs nothing. Tag someone who's been told their symptoms have nothing to do with food.

Perimenopause content is everywhere right now and the autoimmune overlap is barely covered — so here's the nuanced version.

It isn't uniform across conditions. Lupus flare frequency tends to decline after menopause, consistent with estrogen's role in that disease.

Rheumatoid arthritis peaks in incidence between 40 and 60, and Sjögren's shows a female prevalence peak around peri- and post-menopause.

Thyroid autoimmunity is common in this window, and the symptom overlap is a genuine clinical problem — fatigue, brain fog, temperature dysregulation, sleep disruption, and mood changes belong to both perimenopause and thyroid dysfunction, which is precisely how thyroid conditions get missed in women in their forties and fifties for years.

So the practical takeaway isn't "hormones make autoimmunity worse." It's that this transition changes the immune environment in condition-specific ways, and if you're in it with a new or worsening symptom picture, "it's just menopause" deserves a full thyroid panel before it's accepted as the answer.

Intestinal permeability is a real, measurable phenomenon with a substantial research literature — increased permeability is documented in celiac disease, inflammatory bowel disease, and several autoimmune conditions.

What's less settled is the direction of causation, and whether it's driver or consequence varies by condition. Here's our actual complaint, and it's with our own field. Somebody with SIBO, somebody with low stomach acid, somebody with a food sensitivity pattern, and somebody with an inflammatory bowel condition can all present with bloating and fatigue — and all four are routinely handed the identical elimination diet plus glutamine plus collagen protocol. Sometimes it helps. Often it doesn't, and the person concludes gut work doesn't apply to them, when what really happened is they were treated for someone else's problem.

Testing first, protocol second. That order is the whole game.

This is one of the most under-discussed findings in autoimmunity. Arbuckle and colleagues, publishing in the New England Journal of Medicine in 2003, went back through stored military blood samples from 130 people who later developed lupus.

In 88% of them, at least one autoantibody was already present before diagnosis — in some cases up to 9.4 years earlier. There is now comparable data in rheumatoid arthritis and type 1 diabetes.

Why it matters: the immune process is measurable long before it becomes a diagnosis, which reframes what “early” actually means. And if you’re currently symptomatic but have been told your labs are unremarkable, that doesn’t mean nothing is happening. It may mean you’re being measured at one point on a long curve.

Hashimoto’s is an autoimmune process in which the immune system targets thyroid tissue — so the underlying process continues regardless of how well-dosed your medication is.

The triggers worth investigating: intestinal permeability, gluten reactivity in susceptible individuals, selenium and iron status, vitamin D, chronic viral load, environmental exposures, blood sugar instability, chronic stress, and hormonal transitions.

Not all nine will be relevant to you. That’s the point. A note on testing — TSH alone is a screening tool, not a full picture. Free T4, free T3, and TPO and TG antibodies tell you considerably more.

The gut lining holds the highest density of immune tissue in the body — it has to, because it’s the largest surface where the outside world meets the inside of you.

Every day, that barrier makes an enormous number of decisions about what’s food, what’s harmless resident bacteria, and what’s a threat. The microbiome participates in training that system, particularly in early life. This is the mechanistic reason gut health keeps appearing in autoimmune conversations. It isn’t a wellness trope; it’s anatomy.

What it doesn’t mean is that fixing your gut fixes autoimmunity — that’s the oversimplification we’d push back on. It means the gut is one of the most consequential inputs into immune behaviour, and it’s more modifiable than most of the others.

A reference range is built by testing a population and taking the middle 95%. That’s it.

Which means the range describes what’s common in the sampled group — including people who are unwell and including a shifting baseline as population health changes. Two consequences worth understanding.

First, a result can sit at the very bottom of a range and be meaningfully different from one at the top, with both flagged “normal.”

Second, single-point values hide trends — a marker drifting steadily across five years while staying in range is telling you something that no individual result will.

What this doesn’t mean: that reference ranges are useless, or that the “optimal ranges” you find online are validated. Many aren’t, and confidently stated optimal targets are one of the more common ways patients get oversold in this space. What it means is that lab interpretation is a clinical skill, and “everything looks normal” should be the start of a conversation rather than the end of one.

Comment with a marker you’ve been told is normal and we’ll cover interpretation in an upcoming post.

Brain fog is one of the most common complaints we hear and one of the most frequently dismissed, partly because it’s genuinely hard to describe and doesn’t appear on any standard panel. But it isn’t mysterious — it’s a nonspecific symptom, which means the work is differentiating, not guessing.

The eight above account for the large majority of what we see, and several are simple to check: a full thyroid panel, fasting insulin and A1c, B12 and ferritin, vitamin D, and hs-CRP will meaningfully narrow the field.

Several can also coexist, which is why single-cause thinking tends to fail in this context.

If it’s new, rapidly progressive, or accompanied by other neurological changes, that needs evaluation now rather than investigation over time. Otherwise, the path forward is a structured differential — not a supplement.
