In brief 💡
Polycystic ovary syndrome (PCOS) affects around 10% of women of childbearing age, but remains underdiagnosed in 70% of cases. The symptoms of PCOS include irregular menstrual cycles, hyperandrogenism (persistent acne, excessive hair growth, hair loss), metabolic disorders, and fertility issues. The diagnosis is based on the Rotterdam criteria: two of the three criteria of anovulation, clinical or biological hyperandrogenism, and polycystic ovaries on ultrasound.
Have you noticed that your periods have been playing hide-and-seek for several months? That hair is appearing where you didn't expect it, or that your skin is giving you trouble despite all your efforts? These signals your body is sending you deserve your full attention, as they could indicate polycystic ovary syndrome. This complex hormonal condition affects one in ten women, yet it remains largely unknown and underdiagnosed, leaving millions of women uncertain about their symptoms.
At G-Heat, we support women in their daily quest for well-being with our heated belts, and we know how much hormonal imbalances can impact your quality of life, especially your temperature regulation.
This article guides you through the different symptoms of PCOS, their varied manifestations depending on phenotype, and the crucial importance of early diagnosis to preserve your long-term health. You will discover how to recognize the warning signs and regain control over your body.
Menstrual symptoms: the first warning signs of PCOS
Irregular cycles and missed periods: understanding the disruptions
Do your periods come when they want, sometimes every two months, sometimes not at all? This is often the first signal your body sends you. Irregular menstrual cycles are the most common symptom of PCOS, affecting up to 85% of women with the condition. We refer to oligomenorrhea when cycles exceed 35 days, and amenorrhea when periods disappear for three months or more. These disruptions are a direct result of hormonal imbalance, which prevents regular ovulation.
- Cycles longer than 35 days: a classic sign to watch out for during adolescence
- Fewer than 8 cycles per year: a strong indicator of ovulatory dysfunction
- Total unpredictability: impossible to predict when the next period will arrive
Heavy bleeding and dysmenorrhea: when should you be concerned?
When your period finally arrives, it can sometimes be a storm! Women with PCOS may experience heavy and prolonged bleeding because the endometrium thickens more between two widely spaced cycles. Dysmenorrhea, or intense pain that forces you to stay in bed, often accompanies these episodes. This phenomenon is explained by the accumulation of the uterine lining, which, deprived of regular ovulation, develops excessively before being suddenly shed.
Chronic anovulation: impact on fertility and diagnosis
Anovulation is when your body does not release an egg every month, and this is the heart of the problem. Without ovulation, there is no possibility of natural conception, which explains why PCOS is the leading cause of female infertility of hormonal origin. The good news is that anovulation is not inevitable, and there are treatments available to stimulate ovulation when you want to conceive. Your doctor can detect this lack of ovulation by simply measuring your progesterone levels in the middle of your cycle.
Visible signs of hormonal imbalance
Persistent acne and oily skin: understanding cutaneous hyperandrogenism
Did you think you were done with acne after adolescence? PCOS may have other ideas. Hyperandrogenism, the excess of male hormones characteristic of the syndrome, stimulates the sebaceous glands and causes persistent acne in 25 to 30% of affected women. These pimples typically appear on the chin, jawline, and neck, areas that are particularly sensitive to androgens. Unlike classic acne, acne linked to PCOS is often resistant to standard dermatological treatments.
💡 Our expert advice: If your acne persists despite appropriate care and is accompanied by other symptoms such as irregular cycles, ask your doctor for a complete hormonal assessment, including androgen levels.
Hirsutism and excessive hair growth: affected areas and assessment
Hair growing on the face, chest, or stomach can really undermine your self-esteem. Hirsutism affects around 70% of women with PCOS and is one of the most visible signs of hyperandrogenism. Doctors use the Ferriman-Gallwey score to objectively assess this excessive hair growth in nine areas of the body. Beyond the aesthetic aspect, this symptom is a sign of a hormonal imbalance that requires comprehensive treatment.
- Face: chin, upper lip, cheeks
- Body: chest, abdominal line, back, thighs
- Significant score: above 8 points on the assessment scale
Androgenic alopecia: understanding hair loss related to PCOS
While hair invades unwanted areas, it can desert your scalp—how ironic! Female androgenic alopecia manifests as gradual thinning at the center parting and the top of the head. This symptom, present in 20 to 25% of women with PCOS, results from the sensitivity of hair follicles to excess androgens. Early treatment can often slow down this hair loss and stimulate regrowth.
PCOS is not just an ovarian problem; it is a global hormonal imbalance that affects the entire body. Understanding its manifestations means giving yourself the means to take effective action.

Metabolic disorders associated with the syndrome
Unexplained weight gain and insulin resistance
Do you watch what you eat and exercise, yet still find yourself putting on weight? Insulin resistance affects 50 to 70% of women with PCOS and explains this frustrating weight gain. Your body produces more insulin to compensate for its inefficiency, which promotes fat storage and stimulates the production of androgens by the ovaries. This metabolic vicious circle is a major focus of treatment for the syndrome.
Abdominal fat distribution: understanding the mechanism
PCOS has a very specific signature: fat tends to accumulate around the waist. This abdominal adiposity, also known as android obesity, significantly increases cardiovascular and metabolic risks. A waist circumference greater than 31 inches in women is a warning sign, regardless of total weight. This fat distribution is a direct result of the excess androgens and insulin resistance characteristic of PCOS.
| Metabolic Symptom | Prevalence in PCOS | Associated Risk Factor |
|---|---|---|
| Insulin resistance | 50–70% | Type 2 diabetes |
| Overweight/Obesity | 40–80% | Cardiovascular complications |
| Dyslipidemia | 70% | Atherosclerosis |
| Hypertension | Variable | Stroke, heart failure |
Difficulties losing weight despite your efforts: tailored strategies
Do you feel like you're fighting a losing battle just to lose a single pound? That's normal, and it's not because you lack willpower! Insulin resistance makes weight loss particularly difficult for women with PCOS. Traditional diets often work less well, and strategies need to be adapted: focus on foods with a low glycemic index, split meals, and combine endurance exercise with strength training.
⚠️ The trap to avoid: drastic restrictive diets! Abruptly eliminating entire food groups can worsen insulin resistance and further disrupt hormonal balance. Opt for a gradual, balanced approach with nutritional support tailored to PCOS.
Infertility and reproductive complications
Difficulties conceiving: mechanisms and prevalence
Let's be honest, wanting a baby and having irregular cycles don't mix. PCOS is the leading cause of anovulatory infertility, responsible for 70% of cases of ovulation disorders. Without regular ovulation, the chances of natural conception decrease dramatically, but be careful: this does not mean that you will never be able to have children! With appropriate medical support, the majority of women with PCOS are able to conceive.
Recurrent miscarriages: links to PCOS
The path to motherhood can be fraught with additional obstacles when you have PCOS. Studies show an increased risk of early miscarriage, potentially linked to insulin resistance and hormonal imbalances that affect the quality of the endometrium. Close monitoring in early pregnancy and optimizing your metabolism before conception can significantly reduce this risk.
Fertility options for women with the syndrome
The good news is that medicine has made tremendous progress in helping you achieve motherhood! Ovulation-inducing treatments such as clomiphene citrate or letrozole have excellent results in women with PCOS. If these fail, in vitro fertilization (IVF) offers an effective alternative. Often, simply losing 5 to 10% of body weight is enough to restore spontaneous ovulatory cycles.
Supporting women in their daily lives also means understanding the specific challenges they face. Well-being requires a holistic approach that takes into account all aspects of their lives.

PCOS phenotypes: variability of symptoms
Phenotype A: hyperandrogenism and anovulation without cysts
Do you have signs of excess male hormones and irregular cycles, but your ultrasound shows completely normal ovaries? Welcome to PCOS phenotype A! This profile, which accounts for about 30% of cases, perfectly illustrates why the term “polycystic” can be misleading. The absence of visible cysts does not mean the absence of the syndrome, as the diagnosis is based on a combination of several criteria.
Phenotype B: all three diagnostic criteria present
Phenotype B ticks all the boxes: hyperandrogenism, anovulation, and polycystic ovaries. This is the classic and most severe form of the syndrome, affecting about 25% of women diagnosed. These women generally have the most pronounced symptoms and require close medical monitoring to prevent long-term metabolic complications.
Phenotypes C and D: atypical forms and their characteristics
PCOS does not always fit into neat categories, which is what makes it so difficult to diagnose! Phenotype C combines hyperandrogenism and polycystic ovaries without ovulation disorders, while phenotype D combines anovulation and cysts without clinical hyperandrogenism. These milder forms can go unnoticed for years, contributing to the massive under-diagnosis that affects 70% of women with the condition worldwide.
✍️ Author's opinion: What strikes me about PCOS is how different each woman's experience is. One friend may have all the classic symptoms, while another may have an almost silent form. That's why I strongly recommend that you never compare yourself to others and trust your instincts when talking to your doctor.
Long-term complications and medical monitoring
Risk of type 2 diabetes: prevention and screening
Insulin resistance doesn't just cause weight loss difficulties, it also opens the door to type 2 diabetes. Women with PCOS are four times more likely to develop this chronic disease during their lifetime. Regular screening with fasting blood sugar or glycated hemoglobin tests every one to three years allows you to take action before diabetes sets in.
High blood pressure and dyslipidemia: cardiovascular monitoring
Your heart also deserves your attention when you live with PCOS! High blood pressure and dyslipidemia (high cholesterol and triglycerides) are more common in women with this syndrome, increasing overall cardiovascular risk. Regular monitoring of your blood pressure and lipid profile, combined with a healthy lifestyle, is your best long-term protection.
Metabolic syndrome and quality of life: a comprehensive approach
Metabolic syndrome occurs when several risk factors combine: abdominal obesity, high blood sugar, high blood pressure, and dyslipidemia. Present in 30 to 40% of women with PCOS, it has a significant impact on quality of life and long-term health. Treatment must be comprehensive, combining lifestyle changes, psychological support if necessary, and appropriate medication.

FAQ
What are the three Rotterdam criteria for diagnosing PCOS?
The Rotterdam criteria require the presence of at least two of the following three elements: ovulation disorders (irregular or absent cycles), signs of clinical or biological hyperandrogenism, and polycystic ovaries on ultrasound (12 or more follicles per ovary). This diagnosis must be made after ruling out other causes of hormonal imbalance.
At what age can symptoms of polycystic ovary syndrome develop?
The first symptoms of PCOS usually appear at puberty, with irregular cycles from the first period, persistent acne, and sometimes weight gain. However, diagnosis is often delayed until adulthood, when difficulties conceiving lead to consultation.
Can G-Heat thermoregulatory clothing help with PCOS hot flashes?
Absolutely! Our JADECOOL and POLYCOOL technologies provide immediate cooling during episodes of intense heat. For those times when you feel cold, our carbon fiber heating range maintains your comfortable temperature. This dual expertise supports you in all situations.
What is the difference between isolated ovarian cysts and polycystic ovary syndrome?
An isolated ovarian cyst is a pocket of fluid that forms occasionally and often disappears spontaneously. PCOS refers to a complete hormonal syndrome with multiple small follicles (not true cysts) and associated symptoms such as hyperandrogenism and ovulation disorders.
How do G-Heat thermal solutions meet the needs of women with PCOS?
Our range offers thermoregulating thermal clothing that adapts to body temperature fluctuations caused by hormonal imbalances. Whether you need soothing warmth or cooling comfort, our technology responds in real time to your needs for optimal comfort.
Can you have PCOS without experiencing all the classic symptoms?
Yes, it's actually very common! PCOS phenotypes C and D are atypical forms with fewer visible symptoms. Some women have neither acne nor hirsutism, while others have regular cycles. This variability explains why PCOS remains underdiagnosed in 70% of affected women.
