PCOS, or polycystic ovary syndrome, is a common hormone-related condition in women of reproductive age. It can cause irregular periods, high androgen symptoms such as acne or excess facial hair, insulin resistance, weight changes, and fertility problems. Diagnosis usually requires a clinician to review symptoms, labs, and sometimes ultrasound findings 1, 2.

See if you qualify →What is PCOS in women?
PCOS means polycystic ovary syndrome, also called polycystic ovarian syndrome. It is a set of symptoms linked to hormone imbalance, not a single disease that looks the same in every person 2.
What the name means and why PCOS is not just ovarian cysts
The name can be confusing. “Polycystic” refers to many small ovarian follicles that may be seen on ultrasound, but a person can have PCOS without obvious ovarian cysts 2. Clinicians care more about the pattern: ovulation problems, androgen signs, metabolic risk, and other causes that need to be excluded.
How common PCOS is in reproductive-age women
The FDA Office of Women’s Health says PCOS affects 1 out of every 10 women of childbearing age 1. It can begin around puberty, but some people are not evaluated until they have trouble with periods, skin changes, weight, or pregnancy.
Why PCOS can affect periods, skin, metabolism, and fertility
Higher androgen levels can disrupt ovulation, which may lead to irregular menstruation, anovulation, acne, hirsutism, and scalp hair thinning 1, 2. Insulin resistance can also play a role, which is why PCOS often overlaps with weight gain, prediabetes risk, and type 2 diabetes risk 1.
Quick facts about PCOS
PCOS is a syndrome, which means it is diagnosed by a pattern of findings. There is no single blood test or ultrasound result that proves PCOS for everyone 1, 2.
- PCOS is not just a cyst problem; it can affect reproductive, metabolic, cardiovascular, inflammatory, and skin-related health features 2.
- Many people have symptoms beyond the ovaries, including acne, oily skin, excess hair growth, darkened skin patches, skin tags, and weight changes 1.
- PCOS can be managed, but it is not usually described as cured; care focuses on symptoms, pregnancy goals, and long-term risk reduction 1.
- A clinician should consider other causes of irregular periods or androgen symptoms before confirming PCOS 1, 2.
What are the symptoms of PCOS in women?
PCOS symptoms can look different from person to person. The most common pattern includes period changes plus signs of higher androgens, but metabolic and fertility symptoms may be the first clue for some people 1, 2.
Irregular, absent, or unpredictable periods
PCOS can interfere with ovulation, meaning the ovary may not release an egg regularly. That can lead to irregular menstruation, missed periods, or long gaps between periods 2.
Acne, oily skin, excess facial or body hair, and scalp hair thinning
High androgen levels can cause acne, oily skin, hirsutism, and androgenic alopecia, which means scalp hair thinning in a pattern linked to androgen sensitivity 1. These symptoms can be distressing, even when lab results are only mildly abnormal.
Weight gain or difficulty losing weight
Not everyone with PCOS has overweight or obesity. Still, insulin resistance and weight changes often overlap with PCOS, and weight management is considered first-line support when excess weight is part of the picture 1, 3. If this is your main concern, our guide to losing weight with insulin resistance may help you understand the overlap.
Darkened skin patches and skin tags
Dark, velvety skin patches and skin tags can be signs seen with insulin resistance 1. They do not prove PCOS by themselves, but they are worth mentioning during a medical visit.
Infertility or trouble ovulating
PCOS is a common cause of anovulatory infertility, meaning infertility related to not ovulating regularly 2. If pregnancy is a goal, PCOS care should be coordinated with a clinician who can address ovulation, metabolic risk, miscarriage risk, and gestational diabetes risk.
Why symptoms can look different from person to person
One person may have acne and predictable periods. Another may have few skin symptoms but long cycles and insulin resistance. That is why symptom checklists are useful for starting a conversation, but they cannot replace a clinical evaluation 1.
What causes PCOS?
The exact cause of PCOS is not fully known. Research and official guidance point to a mix of hormonal, metabolic, and genetic factors, especially higher androgen levels and insulin resistance 1, 2.
The role of high androgen levels
Androgens are sometimes called “male-type” hormones, but all women make them in smaller amounts. In PCOS, higher androgen levels can interfere with ovulation and contribute to acne, oily skin, unwanted hair growth, and scalp hair thinning 1.
The role of insulin resistance
Insulin helps move sugar from the blood into cells. With insulin resistance, the body needs more insulin to do the same job, and high insulin levels may worsen androgen-related features in PCOS 1. For a deeper plain-language explanation, read what insulin resistance is.
Genetic and family-risk factors
The FDA notes that PCOS risk may be higher when it runs in a family 1. Family history does not mean a person will definitely develop PCOS, but it can guide what a clinician asks and tests.
Why the exact cause is still not fully known
PCOS is likely not one single condition. NICHD notes that more recent genetic research suggests there may be two or more PCOS subtypes 2. That may help explain why two people with the same diagnosis can have different symptoms and different treatment priorities.
Is PCOS a big deal?
Yes, PCOS deserves medical attention, even when symptoms feel mild. It can affect quality of life, fertility, metabolic health, and cardiovascular risk factors, so the goal is not panic; the goal is timely, individualized care 1, 2.
Possible links with prediabetes, type 2 diabetes, and cardiovascular risk factors
PCOS can be linked with diabetes and heart disease risk, and insulin resistance is a key part of that concern 1. Research in women with PCOS also continues to study blood pressure, lipids, and cardiovascular protein responses, showing that PCOS is more than a period problem 7, 8.
Pregnancy and fertility considerations
Because PCOS can disrupt ovulation, it can make it harder to get pregnant 2. If you are trying to conceive, care may include ovulation-focused treatment and monitoring for pregnancy-related risks; our article on PCOS and infertility treatment explains what to ask.
Mental health and quality-of-life considerations
PCOS symptoms can affect mood, body image, relationships, and daily life. In a secondary analysis of four weight-loss trials in women with PCOS and overweight or obesity, higher baseline depressive symptoms were associated with study attrition, which shows why support and follow-up matter 3.
How is PCOS diagnosed?
PCOS diagnosis usually means looking for a pattern and ruling out look-alike conditions. Clinicians often consider ovulation problems, androgen signs or labs, and polycystic ovaries, but there is no single PCOS test 1, 2.
Why there is no single PCOS test
A period history, skin and hair symptoms, weight changes, family history, medications, labs, and sometimes ultrasound can all matter 1. A normal ultrasound does not always rule out PCOS, and polycystic ovaries alone do not always prove it 2.
The usual diagnostic features: ovulation problems, androgen signs, and polycystic ovaries
NICHD describes PCOS as usually involving at least two of three features: absence of ovulation leading to irregular or absent periods, high androgens or signs of high androgens, and growths in one or both ovaries that are often clumps of ovarian follicles that stopped developing 2.
Common lab tests and ultrasound considerations
A clinician may check hormone levels, blood sugar markers, lipids, and other labs based on the person’s symptoms and goals 1. Ultrasound may be used in some cases, but it is only one part of the evaluation 2.
Conditions clinicians may need to rule out first
Other conditions can cause irregular periods, acne, excess hair growth, scalp hair thinning, or fertility problems. That is why PCOS care starts with a careful medical evaluation rather than a self-diagnosis from symptoms alone 1.
Are there four types of PCOS?
Online lists often describe 4 types of PCOS, but those labels can be too simple. Clinicians usually focus on the person’s symptoms, metabolic risk, fertility goals, and medication safety rather than a fixed internet category 1, 2.
Why online PCOS type labels can be oversimplified
Labels such as “insulin-resistant PCOS” or “inflammatory PCOS” may describe part of a person’s picture, but they are not a substitute for diagnosis. Someone can have overlapping features, and the treatment plan may change over time.
How clinicians focus on symptoms, metabolic risk, fertility goals, and safety
A person with irregular periods and no pregnancy goal may need cycle regulation and endometrial protection. A person trying to conceive may need ovulation-focused care. A person with insulin resistance may need metabolic-risk care, including nutrition, exercise, and sometimes medication 1, 2.
What research suggests about PCOS subtypes
NICHD notes that genetic research suggests there may be two or more subtypes of PCOS 2. This is promising, but it does not yet mean most patients can be neatly sorted into one simple type.
What helps manage PCOS?
PCOS management depends on what you are trying to improve: periods, androgen symptoms, fertility, insulin resistance, weight, or long-term risk. Most plans combine lifestyle support, symptom-specific treatment, and follow-up over time 1, 2.
Lifestyle and weight management as first-line support when weight is a factor
For women with PCOS and overweight or obesity, weight management is considered first-line support in international evidence-based guidance cited by a secondary analysis of four randomized weight-loss trials 3. In that analysis of 221 premenopausal women with PCOS and overweight or obesity, about 63% achieved at least 5% weight loss, but attrition was high at 47.1%; individual results vary 3.
Cycle regulation and endometrial protection options
For people who are not trying to conceive, clinicians may use cycle-regulating treatments to reduce unpredictable bleeding and protect the uterine lining 1. The right option depends on pregnancy goals, risk factors, and medication safety.
Treatment options for acne, excess hair growth, and androgen symptoms
Androgen-related symptoms may be managed with skin-directed care, hormonal medicines, or anti-androgen medicines in some patients 1. These choices need clinician oversight because some options are not safe in pregnancy and may require monitoring.
Fertility-focused treatment options
When pregnancy is the goal, treatment focuses on ovulation and safety before and during pregnancy. PCOS is a common cause of anovulatory infertility, but it does not mean pregnancy is impossible 2.
Insulin resistance and metabolic-risk care
Metformin and other insulin-sensitizing approaches have been studied in PCOS for glycemic and lipid outcomes, but the best choice depends on the person’s labs, symptoms, pregnancy goals, and tolerance 4, 9. A 2026 randomized trial studied metformin with or without cabergoline in Iraqi patients with PCOS and hyperprolactinemia, showing how specific the study population can be 5.
Where GLP-1 research fits
GLP-1 receptor agonists have been studied in PCOS-related metabolic care, but they are not PCOS cures or fertility treatments. In a randomized clinical trial, Frøssing and colleagues studied liraglutide, a GLP-1 receptor agonist sold under brand names including Saxenda and Victoza, for ectopic fat outcomes in women with PCOS 6. Benefits must be weighed against side effects such as nausea, vomiting, diarrhea, constipation, gallbladder concerns, pancreatitis warnings, and pregnancy-related safety considerations, which a clinician should review.
| If this is your main situation | A sensible next step | Why it matters |
|---|---|---|
| Irregular or missed periods | See a clinician for pregnancy testing when relevant, hormone evaluation, and cycle-safety planning | PCOS is one possible cause, but not the only cause 1. |
| Acne, excess facial or body hair, or scalp hair thinning | Ask about androgen evaluation and symptom-specific treatment options | High androgen levels can drive skin and hair symptoms 1. |
| Weight gain or difficulty losing weight with signs of insulin resistance | Discuss nutrition, activity, sleep, labs, and whether prescription weight care fits | Weight management can support PCOS care when overweight or obesity is present 3. |
| Trying to conceive | Work with an OB-GYN, reproductive endocrinologist, or fertility-focused clinician | PCOS can cause anovulatory infertility, but treatment is goal-specific 2. |
| Blood sugar, blood pressure, or lipid concerns | Ask about metabolic screening and follow-up | PCOS can overlap with diabetes and heart disease risk factors 1. |
3-min quiz
Wondering whether weight care fits your PCOS picture?
Chia does not treat PCOS itself as a standalone diagnosis. For eligible patients, our licensed providers can evaluate whether weight-care treatment such as compounded semaglutide injection or tirzepatide tablets or injections is clinically appropriate. A prescription requires a medical evaluation and is not guaranteed. Compounded drugs are not FDA-approved.
When weight care for PCOS may fit at Chia
At Chia, weight care for PCOS-related concerns may fit when a patient has weight-management goals and a licensed provider determines prescription treatment is appropriate. This is weight-care support, not a PCOS cure, fertility treatment, or substitute for OB-GYN care.
Who may want to discuss prescription weight care with a clinician
Someone with PCOS symptoms plus overweight, obesity, insulin resistance, or difficulty losing weight may want to discuss medical weight care. That conversation should include side effects, contraindications, pregnancy plans, breastfeeding status, gallbladder history, pancreatitis history, and other medicines.
Chia’s online evaluation process and why prescriptions are not guaranteed
Chia is 100% online. Patients complete a short health questionnaire, then a licensed US provider reviews it and prescribes only where clinically appropriate. Patients can message their care team through the portal between visits, and eligible prescriptions are compounded by state-licensed US 503A pharmacies and shipped to the patient’s door.
Semaglutide at Chia: compounded injection from a state-licensed 503A pharmacy
Chia offers semaglutide as a compounded injection, with microdosing plans available when provider-guided and clinically appropriate. Plans currently start at $249/mo; the product page has current pricing.
Tirzepatide at Chia: tablets or injections, with microdosing plans available
Chia offers tirzepatide, a dual GIP/GLP-1 receptor agonist active ingredient, as compounded tablets and injections, with microdosing plans available when provider-guided and clinically appropriate. Tablet plans currently start at $249/mo, and injection plans currently start at $299/mo.
| Chia option | Forms listed in Chia’s catalog | Current starting price | How it may fit |
|---|---|---|---|
| Semaglutide | Injection | From $249/mo | For eligible patients seeking provider-guided weight care, including microdosing plans when appropriate. |
| Tirzepatide | Tablets or injection | Tablets from $249/mo; injection from $299/mo | For eligible patients who want to discuss tablet vs injection options and provider-guided dosing. |
| Weight + Energy | NAD+ injection + choice of GLP-1 | From $309/mo | For eligible patients whose clinician agrees that weight care plus NAD+ support fits their goals. |
| Weight + Muscle | Sermorelin injection + choice of GLP-1 | From $329/mo | For eligible patients whose clinician agrees that weight care plus sermorelin support fits their goals. |
Weight + Energy and Weight + Muscle protocols for eligible patients
Chia also offers Weight + Energy, which includes NAD+ injection plus a choice of GLP-1, and Weight + Muscle, which includes sermorelin injection plus a choice of GLP-1. These protocols require clinician review, and they are not right for everyone.
Why GLP-1 treatment is weight-care support, not a PCOS cure
GLP-1 and GIP/GLP-1 medicines may be discussed when weight care is clinically relevant, but they do not diagnose PCOS, cure PCOS, or replace fertility care. If you want a broader overview of medication options, see our guide to prescriptions for weight loss.
When should someone seek medical care for possible PCOS?
Seek care when PCOS symptoms are new, worsening, or affecting your life. It is especially important to get evaluated if periods are very irregular, pregnancy is a goal, or you have signs of insulin resistance or blood sugar problems 1, 2.
Irregular periods, missed periods, or heavy bleeding
Periods that are absent, very unpredictable, or unusually heavy deserve medical evaluation. A clinician may need to check pregnancy status, anemia risk, hormone patterns, and whether the uterine lining needs protection.
New or worsening excess hair growth, acne, or scalp hair loss
New or fast-changing androgen symptoms should be checked. PCOS is common, but clinicians may need to rule out other causes, especially if symptoms change quickly.
Trouble getting pregnant
If you are trying to conceive and cycles are irregular, do not wait indefinitely. PCOS can be related to anovulation, and fertility-focused care can help identify the next step 2.
Signs of insulin resistance or blood sugar problems
Darkened skin patches, skin tags, weight gain around the waist, fatigue after meals, high blood sugar, or a history of gestational diabetes are reasons to ask about metabolic screening. PCOS can overlap with prediabetes and type 2 diabetes risk 1.
Urgent symptoms that need prompt in-person care
Seek prompt in-person care for severe pelvic pain, fainting, heavy bleeding, pregnancy with pain or bleeding, chest pain, shortness of breath, or signs of severe dehydration. These symptoms should not be handled through a routine telehealth weight-care visit.

FAQ about PCOS in women
PCOS is usually managed rather than described as cured. Symptoms can improve with the right plan, but follow-up matters because PCOS can affect periods, skin, fertility, insulin resistance, and long-term metabolic risk.
Yes. Some people diagnosed with PCOS do not have obvious growths or follicles on the ovaries. Clinicians look at the full pattern, including ovulation problems and androgen signs.
Yes. PCOS can occur at any body size. Weight and insulin resistance are important for many people, but they are not required for every PCOS diagnosis.
No. PCOS can make ovulation less regular, which can make pregnancy harder for some people, but it does not always cause infertility. If pregnancy is a goal, a fertility-focused clinician can guide testing and treatment.
PCOS is linked with insulin resistance and higher concern for prediabetes and type 2 diabetes. That does not mean everyone with PCOS will develop diabetes, but blood sugar screening is often part of care.
Metformin is an insulin-sensitizing medication that has been studied in PCOS, especially for metabolic outcomes. Whether it fits depends on labs, symptoms, pregnancy goals, side effects, and clinician judgment.
GLP-1 medicines have been studied in PCOS-related metabolic care, but they are not PCOS cures or fertility treatments. Compounded formulations are not FDA-approved and do not have FDA-evaluated outcomes data; a clinician should decide whether weight-care treatment is appropriate.
Ask what else could explain your symptoms, which labs or imaging make sense, how to screen for insulin resistance, how to protect regular bleeding patterns, what to do if pregnancy is a goal, and which treatments are safe for your medical history.
