Inflammatory

This type points at low-grade inflammation. It is the hardest of the four to prove with one test, so this page is mostly about excluding the treatable things that produce the same week.

This pattern describes symptoms driven by chronic low-grade inflammation — the constant, everyday kind rather than the swollen-ankle kind. It shows up furthest from the ovaries: joints, gut, skin, energy. It reaches your hormones indirectly, because inflammatory signalling makes cells less responsive to insulin, which raises insulin and androgens behind it.

Written by Sarah Collins, who is not a doctor or a dietitian, and checked against the 2023 International Evidence-Based Guideline for the Assessment and Management of PCOS. No clinician has reviewed this page. Educational only — it is not medical advice and it was written before you took the quiz.

What this result actually means

The driver: Chronic low-grade inflammation.

Inflammation is a normal repair response. The problem here is a version that never switches off — low grade, constant, driven by something ongoing rather than by an injury you can point at.

It reaches PCOS through the insulin door. Inflammatory signalling makes cells less responsive to insulin, insulin rises to compensate, and the androgen loop that follows is the same one described in the insulin-resistant result. Meanwhile the symptoms that bother you most — the aching, the gut, the skin, the fatigue — are inflammatory in their own right and need no hormonal explanation at all.

Be careful with this category, more than with the other three. "Inflammatory PCOS" describes which lever moves your symptoms. It is not something a clinician can confirm on a form, and the marker most often quoted for it, hs-CRP, tells you inflammation is present without telling you what is causing it — a cold, a bad night and a hard workout all raise it.

What it looks like day to day

You will not have all of these, and having several does not confirm anything on its own. They are here so you can check the result against your own week rather than against a label.

Aching with no injury behind it — hands, knees, lower back — worse on some mornings than others.
Recurrent headaches that do not track your cycle.
Gut symptoms you have stopped mentioning: bloating that arrives by evening, unpredictable stools, reflux.
Skin that flares — eczema, hives, redness — alongside the hormonal acne rather than instead of it.
Fatigue that a good night of sleep does not resolve.
A strong sense that symptoms swing with something you ate, without ever having pinned down what.

Three things worth changing first

In this order. Each one is chosen because it acts on the driver above rather than on PCOS in general, and because you can start it this week without buying anything.

Ask for coeliac blood tests before you cut gluten

Coeliac testing measures your immune response to gluten, so removing gluten first makes the result unreliable — and getting back on it for weeks in order to retest is genuinely miserable. Coeliac disease produces this exact symptom set and is worth excluding before you spend three months guessing.

Start with: Book it before you change anything you eat. Ask for tTG-IgA with a total IgA, and keep eating gluten normally until the blood is drawn.

Test one food group, once, for three weeks — and write it down

Cutting dairy and gluten and sugar and soy in the same week tells you nothing except that you feel different, and it usually ends in a smaller diet than you started with. One variable at a time is the only version of this that produces an answer you can act on.

Start with: Pick the one you most suspect. Remove it fully for three weeks. Score your three worst symptoms out of ten every day. Then reintroduce it properly for three days and score again. Keep it out only if the reintroduction is clearly worse — and put it back if it is not.

Add before you remove

Every food removed is a food you now have to work around at every meal, every restaurant and every family dinner, and restriction carries its own cost. The eating pattern with the most consistent evidence behind it for inflammation is additive rather than subtractive.

Start with: This week: two portions of oily fish, olive oil as the default fat, one legume-based meal. Count how many different plants you eat across a week once, as a baseline. Most people are surprised how low the number is.

What not to do first

Do not start with a long supplement stack. Half of it is doing nothing for you specifically, it costs more than the food does, and once four things start in the same week you have lost the ability to tell which one earned its place.

The bloodwork to ask for

Take this list to the appointment rather than the page. You are asking for tests, not interpreting them — the numbers only mean something next to your history, your medications and each other, which is the part a clinician does and a quiz cannot.

What to ask for if your answers point at inflammatory
Test	Why it is on this list	Worth knowing
hs-CRP	The general inflammation marker. The high-sensitivity version is the one that reads the low-grade range; standard CRP is built for infections.	Non-specific by design. Do not have it drawn during or just after an illness.
Full blood count	Picks up anaemia and the blood-cell patterns that come with chronic inflammation.	Cheap, routine, and often already sitting in your file.
Ferritin with iron studies	Low iron produces this precise fatigue. Ferritin also rises with inflammation, which is why it is read alongside the rest rather than alone.	Ask for the iron studies, not ferritin on its own.
TSH, free T4, thyroid antibodies	Autoimmune thyroid disease overlaps heavily with this symptom picture and is treatable.	Antibodies get left off. Ask for anti-TPO by name.
Coeliac serology	See the first action. Only meaningful while you are still eating gluten.	tTG-IgA with a total IgA — without the total IgA a false negative is possible.
Vitamin D	Commonly low, straightforward to correct, and worth knowing before you decide anything else is the cause.	Ask for the actual number rather than "normal".
HbA1c and fasting insulin	Because inflammation and insulin resistance travel together, and the second of the two is easier to act on.	The insulin-resistant result explains how to read these.

None of these confirms an "inflammatory" type, and no test does. What they do is rule out the treatable conditions that produce the same week — anaemia, thyroid disease, coeliac disease, low vitamin D — before you spend six months on an elimination diet for something that had a blood test.

Where this overlaps with the other three

Inflammation and insulin resistance reinforce each other in both directions, so matching both results is the expected outcome rather than a contradiction. If you recognised the afternoon crashes and the carb cravings too, read that result next and work the two together.

If two of the four sounded like you, that is the normal outcome rather than a failed quiz. Work the one whose first actions are cheapest for your life right now, give it eight weeks, and read the others when you have something to compare against.

What this result is not

PCOS is diagnosed against the Rotterdam criteria — irregular or absent ovulation, signs of raised androgens on examination or in bloodwork, and the appearance of the ovaries on ultrasound — with two of the three required and other causes excluded first. A questionnaire cannot assess any of the three.

The four types on this site are working categories for sorting advice by what is driving it. They are not a formal classification, they are not the phenotypes used in the research literature, and no blood test confirms them. They are useful because generic PCOS advice averages four different problems into one answer, and the average fits nobody.

So take the bloodwork list and the timeline. Leave the label here.
