PCOS Symptoms and Treatments: A Pre-Test Checklist

You have been Googling this for months. Every site has the same generic list, you fit some of it and not other parts, and you cannot tell if your symptoms are PCOS, a thyroid issue, plain stress, or normal life. This is the checklist I would want you to bring to the appointment, so you leave with a proper workup instead of a vague reassurance.

The clinical picture for PCOS is a pattern, not a single sign. PCOS symptoms and treatments line up against the Rotterdam criteria from the 2023 international PCOS guideline, which needs two of three features (irregular ovulation, androgen excess, polycystic ovarian morphology or elevated AMH), with all other causes ruled out first.¹ But the criteria are tested at the appointment. The symptoms come first, and the better you can describe them, the faster the right tests get ordered. I have seen the same person walk out of two different appointments with completely different plans, depending on how they described what was happening at home.

If you want the full diagnostic framework, the pillar post How PCOS Is Diagnosed: The Rotterdam Criteria Explained sits alongside this one. The post you are reading now is about what to track, what to photograph, and what to say in the room.

Why a symptom list comes before the test list

PCOS is a clinical pattern, not a single lab. Vague complaints get vague workups. If you describe "my periods are weird and I have some skin stuff," a busy clinician will reach for the screening tests in their head and may miss the targeted ones. If you describe "my last six cycles were 42, 38, 51, 29, 47, and 33 days, my acne is along my jawline and started in my mid-twenties, and I have new dark hair on my chin," the same clinician orders a specific panel and a transvaginal scan in the right cycle phase.

Tracking even two or three cycles before the visit changes the conversation. You do not need an app for this; a notes file with the date each period started and the date each period ended is enough. If you are already using ovulation predictor kits or basal body temperature, bring that too. The clinician will be able to tell more from raw data than from a summary.

The three symptom clusters

PCOS symptoms in women cluster in three buckets: menstrual and ovulatory signs, androgen-excess signs, and metabolic signs. The pattern that fits PCOS usually includes at least one from the first two groups, often with at least one from the third. Not everyone has all three.

Menstrual and ovulatory signs

These are the most specific. In an adult who is not on hormonal contraception:

• Cycles longer than 35 days or shorter than 21 days
• Fewer than 8 periods per year
• Cycles that come unpredictably (28 days, then 47, then 33)
• Heavy bleeding after a long gap, which is endometrial buildup from anovulatory cycles
• Difficulty pinpointing ovulation on OPKs (multiple LH surges across one cycle, or no clear surge at all)
• Pre-menstrual spotting that runs for several days, or breakthrough bleeding mid-cycle

Cycles between 21 and 35 days are within the normal adult range. If yours fall there, you can still have PCOS (phenotype C, the ovulatory PCOS pattern, accounts for about 15 to 20 percent of cases), but the diagnosis hinges more on the next two clusters.

Androgen-excess signs

These are the visible signs that androgens are higher than they should be. The 2012 hirsutism consensus statement from AE-PCOS is still the reference for how to score them.²

• Hirsutism: dark terminal hair (not fine, light hair) in a male-pattern distribution: upper lip, chin, jawline, chest, lower abdomen, inner thighs. Scored with the modified Ferriman-Gallwey scale, where 4 to 6 or higher is considered abnormal depending on ethnicity.²,³
• Persistent adult acne, especially along the jawline and lower face, often worse around the menstrual changes
• Androgenic alopecia: thinning at the crown of the scalp or widening of the part line
• Skin tags, particularly on the neck or in skin folds
• Oily skin or seborrhoea

Two important calibrations. First, the Ferriman-Gallwey score underestimates androgen excess in East and Southeast Asian patients, who have less terminal hair at the same hormone level.³ If you are in this group and your score is low but your skin or your lab numbers look androgenic, ask for biochemical testing. Second, if hirsutism came on suddenly, with deepening voice or other virilising features, that is not routine PCOS. It needs urgent androgen-secreting tumour evaluation, not a slow workup. The threshold I use clinically is total testosterone above 5 nmol/L (150 ng/dL) with sudden onset, but the speed of change matters more than the absolute number.

Metabolic and weight signs

The metabolic side of PCOS is real but does not announce itself the same way the first two clusters do. The signs to look for:

• Difficulty losing weight despite consistent dietary changes, particularly weight that sits around the waist (central adiposity)
• Acanthosis nigricans: velvety dark patches on the back of the neck, in the armpits, or in the groin. This is a visible marker of insulin resistance.
• Strong cravings for refined carbohydrates, and reactive hypoglycaemia (shakiness, sweating, or irritability two or three hours after a high-carb meal)
• Family history of type 2 diabetes, gestational diabetes, or PCOS in a sibling or parent

A normal BMI does not exclude PCOS. The systematic review by Lim and colleagues found a wide BMI distribution across PCOS populations, with a meaningful minority at normal weight.⁴ If you have classic symptoms but a normal BMI, Lean PCOS: When You Don't Match the Stereotype is written for you.

Symptoms that are not PCOS

A surprising number of conditions imitate PCOS, and the workup is supposed to rule them out before the label gets applied. The ASRM evaluation of amenorrhoea is still a good reference for this differential.⁵

• Hot flashes, vaginal dryness, and missing periods in your late 30s or 40s point toward primary ovarian insufficiency or perimenopause. Ask for FSH and AMH.
• Galactorrhoea (milky nipple discharge) with missing periods points toward elevated prolactin. Ask for a fasted morning prolactin.
• Fatigue, cold intolerance, dry skin, and weight gain with constipation point toward hypothyroidism. Ask for TSH with reflex free T4.
• Sudden, severe hirsutism with virilising features (deepening voice, clitoromegaly, rapid hair growth) is urgent. This is not routine PCOS and needs an androgen-secreting tumour workup.
• Loss of periods after weight loss, heavy exercise, or significant stress can be hypothalamic amenorrhoea. It looks similar to PCOS on the cycle history but has the opposite hormonal pattern (low LH, low FSH, low oestradiol).

Each of these has a separate post in this section. The PCOS workup should test for them before settling on the PCOS label, because the treatments diverge sharply.

What to bring to your appointment

Most of the value in the visit comes from what you bring, not what you ask. If you do nothing else before the appointment, bring this:

1. A simple cycle log of at least three cycles. The date each period started, the date it ended, and the cycle length. A line of text per cycle is enough.
2. A symptom checklist with onset dates. Acne since age 15 is different information from acne new in your thirties. Same for hair changes.
3. Photographs of skin changes (acanthosis, hirsutism pattern) if you are comfortable. These do not need to be clinical; phone shots from a few weeks apart are fine.
4. Family history. Type 2 diabetes, gestational diabetes, PCOS, or early heart disease in first-degree relatives matters.
5. Medication and supplement list, including any hormonal contraception you have been on in the last three months. Combined oral contraceptives suppress androgens and ovulation and mask the PCOS picture; the diagnostic workup is not interpretable on the pill.

The 2023 guideline explicitly recommends that the visit produce a full Rotterdam assessment in one go rather than a piecemeal workup over multiple visits.¹ You can hold your clinician to that.

What your clinician should do

A complete PCOS workup at the first visit, based on the 2023 international guideline, includes:

• A directed blood panel (see The PCOS Blood Test Panel for the specific tests and the cycle days)
• A transvaginal ultrasound with a high-frequency (≥ 8 MHz) probe (see PCOS on Ultrasound for what the report should contain)
• Tests to rule out alternative causes: TSH, prolactin, 17-hydroxyprogesterone
• Application of the Rotterdam criteria with a clear statement of which features you meet
• A metabolic screen: fasting glucose, HbA1c, ideally a 2-hour oral glucose tolerance test, a fasting lipid panel, blood pressure, and waist circumference¹

If the visit ends with "your cycles are just irregular, come back if you want to conceive," that is not the 2023 guideline. The recommendation now is to assess and label early, because the metabolic and reproductive consequences accumulate over years.¹

What to do this week

Three concrete things you can do before the appointment:

1. Start logging cycles. Today's date, the date of the start of your last period, and your best guess at how the last three cycles ran.
2. Photograph any skin changes you are tracking, in consistent lighting. Date the photos.
3. Write down a one-line symptom history with onset dates, so you do not freeze in the room.

If your appointment is more than two months away and your cycles are running long, ask whether a phone or video consultation can get the bloods and the scan booked in the meantime. Most of the workup can be done by the time you sit down with the clinician.
