Polycystic ovary syndrome (PCOS) is a hormonal condition affecting 1 in 10 women of reproductive age. It is characterised by irregular or absent ovulation, elevated androgen levels, and small follicles on the ovaries visible on ultrasound. A formal PCOS diagnosis requires at least two of these three features — known as the Rotterdam criteria.
PCOS is not one condition — it presents differently in every woman. Some have classic symptoms like facial hair and acne. Others have only irregular periods or unexplained weight gain. Many women go years without a diagnosis because their symptoms seem unrelated. This checker helps you identify which symptoms align with PCOS so you can have a more informed conversation with your doctor.
Common PCOS Symptoms
PCOS affects multiple body systems. The symptoms below are driven by elevated androgens, insulin resistance, or disrupted ovulation — the three core mechanisms behind the condition.
- Irregular or absent periods — cycles longer than 35 days or fewer than 8 periods a year
- PCOS beard and facial hair — excess hair growth on the chin, upper lip, chest, or abdomen (hirsutism) caused by elevated testosterone
- Acne — particularly along the jawline, chin, and chest, linked to androgen excess
- Hair thinning or loss — male-pattern thinning at the crown or temples
- PCOS bloating — abdominal bloating linked to insulin resistance and gut dysbiosis common in PCOS
- Weight gain — particularly around the abdomen, driven by insulin resistance
- PCOS brain fog — difficulty concentrating and mental fatigue, thought to be linked to insulin dysregulation affecting the brain
- Skin darkening — patches of dark skin in skin folds (acanthosis nigricans), a sign of insulin resistance
Frequently Asked Questions
Does PCOS cause painful periods?
PCOS itself does not typically cause painful periods — in fact, many women with PCOS have infrequent or light periods due to irregular ovulation. However, when periods do occur after a long absence, the uterine lining may be thicker, causing heavier bleeding and more cramping. If you have PCOS and severe period pain, endometriosis should also be ruled out.
Can birth control cause PCOS?
No — birth control does not cause PCOS. However, coming off hormonal contraception can unmask PCOS symptoms that were previously suppressed. Many women are diagnosed with PCOS after stopping the pill when their periods become irregular or do not return. The pill does not create the condition — it masks it.
What is the best age to get pregnant with PCOS?
Women with PCOS can conceive at any reproductive age, but fertility does decline with age as it does for all women. The most important factor is not age but whether you are ovulating. Many women with PCOS conceive naturally with lifestyle changes, ovulation induction medication like letrozole, or IVF. Speaking to a reproductive endocrinologist in your late 20s or early 30s gives you the most options.
Does PCOS cause bloating?
Yes. Bloating is a common complaint in women with PCOS, driven by insulin resistance, gut microbiome changes, and inflammation. Reducing refined carbohydrates and sugar often helps. Some women find that inositol supplementation — particularly myo-inositol — improves both insulin sensitivity and bloating over time.
Can PCOS cause brain fog?
Yes. Brain fog — difficulty concentrating, mental fatigue, and memory issues — is increasingly recognised as a PCOS symptom. Research suggests that insulin resistance may impair glucose delivery to the brain, affecting cognitive function. Managing blood sugar through diet and exercise is one of the most effective ways to reduce PCOS brain fog.
Is this PCOS checker a medical diagnosis?
No. This tool is for educational purposes only. A formal PCOS diagnosis requires blood tests (LH, FSH, testosterone, AMH, fasting insulin), a pelvic ultrasound, and clinical assessment by a doctor. If your results suggest a high risk, we strongly recommend booking an appointment with your GP or a reproductive endocrinologist.
This checker does not constitute medical advice or diagnosis. PCOS is a complex condition that requires clinical evaluation. Always consult a qualified healthcare provider for an accurate assessment and treatment plan.
