PCOS: Full List of Symptoms and How to Recognise Them

PCOS: Full List of Symptoms and How to Recognise Them

Polycystic Ovary Syndrome (PCOS) is one of the most common hormonal disorders affecting women of reproductive age: it affects between 5 and 15% of women, depending on the study. Yet it remains very often undiagnosed, sometimes for years. The reason? Its symptoms are multiple, varied, and easily confused with other conditions.

Here is a comprehensive list of PCOS symptoms, categorised to help you better understand what you may be experiencing — and to start a conversation with your doctor.

Important reminder: PCOS cannot be self-diagnosed. If you recognise several of these symptoms, speak to your GP or gynaecologist. Diagnosis is based on specific criteria: blood tests (hormones, blood glucose), pelvic ultrasound, and clinical assessment.

What Is PCOS?

PCOS is a hormonal imbalance characterised by three main elements (the Rotterdam Criteria): irregular or absent cycles, excess androgens (male hormones), and/or polycystic ovaries visible on ultrasound. For a PCOS diagnosis, two of these three criteria must be present.

This hormonal imbalance triggers a cascade of symptoms affecting fertility, skin, weight, metabolism, and overall wellbeing.

Menstrual and Gynaecological Symptoms

This is often the first sign that raises concern. PCOS cycles are typically:

  • Irregular or widely spaced (oligomenorrhoea): cycles of more than 35 days
  • Absent for several months at a time (amenorrhoea)
  • Sometimes very heavy when they do occur, due to the build-up of the uterine lining
  • Accompanied by pelvic pain, sometimes similar to endo
  • Associated with difficulty conceiving (infertility linked to irregular or absent ovulation)

Skin and Hair Symptoms

Excess androgens (hyperandrogenism) often manifest visibly on the skin and hair:

  • Persistent hormonal acne, particularly on the chin, cheeks, and neck
  • Hirsutism: unwanted hair growth in typically masculine areas (upper lip, chin, abdomen, chest, back)
  • Androgenetic alopecia: hair thinning or loss at the crown of the head
  • Oily skin
  • Acanthosis nigricans: dark, velvety patches in skin folds (neck, armpits, groin) — often a sign of insulin resistance

Metabolic Symptoms

PCOS is closely linked to insulin resistance in around 70% of affected women, which produces specific metabolic symptoms:

  • Difficult-to-control weight gain, particularly around the abdomen
  • Difficulty losing weight despite a balanced diet
  • Intense cravings, particularly for sugar
  • Chronic fatigue after meals
  • Increased long-term risk of prediabetes and type 2 diabetes

Psychological Symptoms

Often underestimated, the psychological impact of PCOS is real and well documented:

  • Increased anxiety and irritability, often linked to hormonal fluctuations
  • Depressive episodes, sometimes cyclical
  • Negative body image linked to visible symptoms (acne, unwanted hair, weight)
  • Sleep disturbance and chronic fatigue
  • Amplified premenstrual syndrome (PMS)

Symptoms Vary from Woman to Woman

This is one of the defining features of PCOS: there is no single typical profile. Some women have irregular cycles with no acne or weight issues. Others are slim but have severe hirsutism. Others have no visible symptoms at all and discover their PCOS during a fertility assessment.

There are generally four PCOS phenotypes depending on the combination of symptoms present — which explains why two women with the same diagnosis can have very different experiences.

When to See Your GP

Speak to your GP or gynaecologist if you have at least two of the following signs:

  • Irregular periods (fewer than 8 cycles per year, or cycles of more than 35 days)
  • Persistent hormonal acne resistant to topical treatments
  • Excessive hair growth on the face or body
  • Difficulty conceiving after 12 months of unprotected sex
  • Unexplained abdominal weight gain with fatigue

What about painful periods?

PCOS can be accompanied by very painful periods, particularly when cycles are long and the uterine lining has built up. The Paingone Ellune can help relieve this pain without medication — it is compatible with all types of hormonal treatments prescribed for PCOS.
