PCOS symptoms diagnosis and management

What PCOS looks like in real life

PCOS produces a cluster of symptoms, though the specific combination varies between women. Recognising the pattern is the first step toward diagnosis.

Cycle issues

Irregular periods are one of the most common features. Cycles may be longer than 35 days, very irregular or absent altogether. Some women have heavy painful periods. Others have very light infrequent ones. The pattern reflects the inconsistent ovulation that defines PCOS. Some women on hormonal contraception have masked cycles, which can delay diagnosis.

Skin and hair changes

Acne that persists into adulthood or appears for the first time in adulthood is common. Excess hair growth, particularly on the face, chest or abdomen, can be distressing. Some women experience hair thinning on the scalp. These symptoms reflect higher androgen levels in PCOS. The combination can be a strong clue toward diagnosis.

Weight and metabolic issues

Many women with PCOS struggle with weight, particularly around the abdomen. Insulin resistance contributes to weight gain and makes losing weight harder than for women without PCOS. Energy crashes, intense cravings and difficulty losing weight despite reasonable effort all suggest the metabolic side of PCOS. Not all women with PCOS are overweight.

Other features

Mood changes including anxiety and depression are more common in women with PCOS. Sleep problems including sleep apnoea occur more frequently. Skin tags and darkened skin patches in body folds (acanthosis nigricans) reflect insulin resistance. Fertility difficulties may be how PCOS is first identified for some women.

How PCOS is identified

Diagnosis of PCOS uses a combination of clinical assessment, blood tests and sometimes imaging. The process can take time, partly because the symptoms overlap with other conditions.

The Rotterdam criteria

Most diagnoses use the Rotterdam criteria, which require any two of three features: irregular or absent ovulation, clinical or biochemical signs of excess androgens plus polycystic ovaries on ultrasound. Other conditions that could cause the symptoms need to be ruled out first. This means PCOS can be diagnosed in women with normal looking ovaries on scan if other criteria are met.

Blood tests

Blood tests check testosterone, SHBG (sex hormone binding globulin), prolactin, thyroid function, FSH and LH. The pattern of results helps confirm PCOS and rule out other conditions. Blood sugar, HbA1c and cholesterol may be checked to assess metabolic health. Speak to your GP about the relevant tests for your situation.

Ultrasound

Pelvic ultrasound may show polycystic ovaries, where many small follicles appear in the ovaries. The term cysts is misleading because these are not really cysts but partially developed follicles. Having polycystic ovaries on scan is not the same as having PCOS. The diagnosis requires the wider picture, not just the scan finding.

The diagnosis delay problem

Many women wait years between first noticing symptoms and getting a diagnosis. If you have symptoms suggesting PCOS, be specific with your GP about what you are experiencing. Ask directly about PCOS as a possibility. If your concerns are not being taken seriously, request a referral to a gynaecologist or endocrinologist. Persistence often pays off.

What works day to day

PCOS management depends on which symptoms matter most to you. Different priorities lead to different treatment approaches.

For irregular cycles

The combined contraceptive pill regulates cycles for most women with PCOS and provides protection for the uterine lining. Hormonal IUDs are an alternative. Metformin can help cycles become more regular by improving insulin sensitivity. For women trying to conceive, ovulation induction with letrozole or clomifene is typically the first line. Speak to your GP about your options.

For acne and unwanted hair

The combined pill helps with both acne and unwanted hair growth for many women. Anti androgen medications can be added in some cases. Topical treatments and hair removal methods address the cosmetic aspects. Effects take 3 to 6 months to become apparent and persistence is needed. Specialist dermatology input helps in difficult cases.

For weight and metabolic health

Lifestyle changes are particularly powerful in PCOS because they target the underlying insulin resistance. Strength training, walking, limiting refined carbohydrates and ultra processed foods, adequate sleep and managing stress all help. Even modest weight loss (5 to 10 percent for those who are overweight) often improves symptoms significantly. Metformin can support metabolic management.

For mental health

Anxiety and depression in PCOS warrant the same treatment approaches as in women without PCOS. The combination of medical and psychological treatment often works. Some women find that improving the physical aspects of PCOS also improves mental health. Specialist mental health support is appropriate if symptoms are significant. Speak to your GP.

PCOS through the lifespan

PCOS is lifelong, though it evolves with age. Knowing what to expect helps you plan around the condition.

Through reproductive years

PCOS symptoms vary with age. Acne and unwanted hair often peak in the twenties and gradually improve. Cycle issues may persist throughout reproductive years. Fertility challenges affect many women with PCOS, though most can conceive with appropriate support. Active management through these years pays off long term.

During pregnancy

Women with PCOS who conceive face slightly elevated risks including gestational diabetes, pre eclampsia and miscarriage. Most pregnancies go well with appropriate monitoring. The same lifestyle factors that help PCOS support pregnancy outcomes. Your antenatal team will likely monitor things more closely.

Through perimenopause

PCOS may produce slightly delayed menopause and slightly more disruptive perimenopausal symptoms. The metabolic and cardiovascular risks become more prominent in this phase. The hormonal patterns that defined PCOS through reproductive years influence the transition. Ongoing attention to metabolic health remains important.

After menopause

PCOS does not disappear when periods stop. The metabolic and cardiovascular risks continue and warrant active management. Type 2 diabetes risk remains elevated. Regular health checks with your GP help track the markers that matter. The active management that served you through reproductive years continues to pay off in later life.
