What Is PCOS?Irregular Periods, Chin Hair, Acne and the Condition Behind Them

How polycystic ovary syndrome, now also called PMOS, links irregular periods, extra hair, acne and thinning hair, how it's diagnosed, the health risks worth screening for, and what treatment can do.

Your periods come when they want. There’s a dark hair on your chin you pluck most mornings. Your skin breaks out around your jaw, your hair is thinner at the part, and the scale hasn’t moved despite your best efforts. Each problem has its own explanation, and you’ve been given a different one every time.

What it can look like

The lists from the three sources overlap.

  • Periods. Irregular or missed periods, or long gaps, per the NHS1, OWH3 and Cleveland Clinic2. See late or irregular periods.
  • Extra hair. OWH3 says excessive facial and body hair affects up to 70% of women with PCOS. Cleveland Clinic2 lists heavy hair growth on the arms, chest and abdomen. See chin hairs.
  • Acne. All three list it. See adult acne.
  • Thinning hair. OWH3 and Cleveland Clinic2 list scalp hair thinning, and the NHS1 lists hair loss. See why your hair is thinning.
  • Weight. OWH3 lists difficulty managing weight, and Cleveland Clinic2 says obesity affects 40% to 80% of people with it.
  • Skin. Patches of dark skin, especially in folds of the neck and armpits, and OWH3 adds skin tags. See dark patches and skin tags.
  • Mood, energy and fertility. The NHS1 lists mental health issues, fatigue and fertility difficulties.

Not everyone has all of them. That’s part of why it’s missed.

Why it happens

The exact cause is unknown, OWH3 and the NHS1 say. The pieces they describe: genes, high levels of androgens, which OWH says can prevent the ovaries from releasing an egg each cycle, and insulin. Cleveland Clinic2 says insulin can cause the ovaries to make and release androgens, which suppresses ovulation, and that people with PMOS tend to have chronic low-grade inflammation. The NHS says it may be to do with hormones such as insulin and testosterone not working properly, and that Asian ancestry may raise the risk.

How it’s diagnosed

There’s no single test. OWH3 says doctors use a physical exam, pelvic ultrasound and blood tests, and that you may be diagnosed if you have at least two of several criteria: irregular periods, signs of high androgens or multiple ovarian cysts. Cleveland Clinic2 says it’s diagnosed with at least two of three features: irregular or missed periods, signs of excess androgens, or a polycystic appearance of the ovaries on ultrasound. The NHS1 says doctors check hormone and insulin levels in blood, with an ultrasound for patients 18 and older.

Why it’s worth getting diagnosed

It isn’t only about periods and hair. OWH3 says more than half of women with PCOS will have diabetes or prediabetes before age 40, and lists high blood pressure, unhealthy cholesterol, sleep apnea, depression, anxiety and endometrial cancer. The NHS1 lists type 2 diabetes, high blood pressure, cardiovascular disease, fatty liver disease and uterine cancer, and says regular monitoring is important. Cleveland Clinic2 lists diabetes, hypertension, cardiovascular disease and depression.

What treatment looks like

The NHS1 says there’s no cure, but there are treatments and lifestyle changes that can help. The treatments depend on what you need.

  • For irregular periods: hormonal birth control, per the NHS1, OWH3 and Cleveland Clinic2.
  • For extra hair: the NHS1 mentions spironolactone, an anti-androgen, and OWH3 and Cleveland Clinic2 list anti-androgen medicines. OWH also lists hair removal.
  • For insulin and weight: metformin, which Cleveland Clinic2 calls an insulin-sensitizing medicine, and lifestyle changes including weight loss, per OWH3.
  • For getting pregnant: the NHS1 and Cleveland Clinic2 mention medicines to induce ovulation, such as clomiphene or letrozole, IVF, and in some cases surgery.
The play

Try this: a symptom timeline

Write down when your periods started to change and how many cycles you’ve had in the last year.

List hair, skin and weight changes, with approximate dates, and whether anyone in your family has PCOS, diabetes or irregular cycles.

Add every medicine and supplement you take. A timeline gets you further than “everything is off.”

When to get checked

The NHS1 says to see a GP if you think you may have PMOS or your symptoms affect your everyday life, work and relationships. Cleveland Clinic2 says to contact a provider for irregular menstrual cycles, excess hair growth, acne or difficulty getting pregnant. OWH3 says to seek care for irregular periods or fertility concerns.

Book an appointment if any of these fit:

  • Your periods are irregular or you’ve missed several in a row
  • You have new hair growth on your face, chest or abdomen, or thinning at your scalp
  • Acne persists despite treatment
  • You’re gaining weight without a clear reason, or have darkened skin patches
  • You’re trying to get pregnant and cycles are unpredictable
  • You have family members with diabetes or PCOS

One thread, many symptoms. A single appointment can tie them together.

If you are trying to get pregnant, or are on any hormonal medicine, talk with your own clinician before changing your treatment.
