PCOS (Polycystic Ovary Syndrome): What Every Woman Should Know
One of the most common hormonal conditions, and one of the most underdiagnosed
1 in 10women of childbearing age
Last reviewed: April 2026
Polycystic ovary syndrome (PCOS) is one of the most common hormonal disorders in women, affecting roughly 1 in 10 women of reproductive age. Despite how common it is, many people go years without a diagnosis because symptoms can look like other conditions or get brushed off as "just stress."
PCOS is not just a reproductive issue. It is a whole-body hormonal condition that affects your metabolism, skin, hair, mood, and long-term health. The name is a bit misleading because not everyone with PCOS actually has cysts on their ovaries.
The causes are not fully understood, but genetics, insulin resistance, and inflammation all play a role. There is no cure, but PCOS is very manageable with the right treatment plan. Arizona has a growing number of OB-GYNs and endocrinologists who specialize in PCOS management, particularly in the Phoenix and Tucson areas.
What Is Actually Happening in Your Body?
In PCOS, the ovaries produce higher-than-normal amounts of androgens, which are sometimes called "male hormones" (though all women produce some). This hormonal imbalance can prevent eggs from developing properly or being released during ovulation.
Many women with PCOS also have insulin resistance, meaning their bodies make insulin but do not use it efficiently. This drives the ovaries to produce even more androgens, creating a cycle that feeds itself. Over time, insulin resistance can lead to type 2 diabetes, which is why early management matters.
Symptoms to Watch For
PCOS symptoms usually start around puberty but can appear later. Common signs include irregular or missed periods, heavy periods when they do come, excess hair growth on the face, chest, or back (hirsutism), acne (especially along the jawline and chin), thinning hair on the scalp, weight gain or difficulty losing weight, darkened skin patches (especially in skin folds), and skin tags.
You do not need every symptom to have PCOS. Some women have mild symptoms while others experience significant disruption to their daily lives.
How Is PCOS Diagnosed?
There is no single test for PCOS. Most providers use the Rotterdam criteria, which require at least two of the following three: irregular or absent ovulation (usually showing up as irregular periods), elevated androgen levels (confirmed by blood tests or visible signs like excess hair growth and acne), and polycystic-appearing ovaries on ultrasound.
Your provider will also rule out other conditions that mimic PCOS, such as thyroid disorders, adrenal hyperplasia, and elevated prolactin levels. Diagnosis can feel frustrating because it often takes multiple visits and tests. Bring a list of your symptoms and cycle history to your appointment.
Early Diagnosis Matters
PCOS is more than a cosmetic or reproductive concern. Left unmanaged, it increases your risk for type 2 diabetes, cardiovascular disease, endometrial cancer (from prolonged periods without ovulation), sleep apnea, and depression and anxiety. Getting a diagnosis early gives you the chance to manage these risks before they become serious problems.
Treatment Options
Treatment depends on your symptoms and whether you are trying to get pregnant. For menstrual regulation, hormonal birth control (pills, patch, or ring) is the most common first step. It regulates periods, reduces androgen levels, and protects the uterine lining.
For insulin resistance, metformin helps your body use insulin more effectively and can improve ovulation. Lifestyle changes, especially diet and exercise, are foundational. For unwanted hair growth and acne, anti-androgen medications like spironolactone can be very effective. For fertility, medications like letrozole or clomiphene citrate can stimulate ovulation.
The Role of Diet and Exercise
There is no specific "PCOS diet," but eating patterns that improve insulin sensitivity make a real difference. Focus on whole grains, lean proteins, vegetables, and healthy fats. Limit added sugars and highly processed foods. Even a modest weight loss of 5 to 10% can significantly improve symptoms and ovulation.
Regular exercise helps with insulin resistance, mood, and weight management. Aim for 150 minutes per week of moderate activity. In Arizona, swimming and indoor classes are great summer options when outdoor temperatures make exercising outside impractical.
PCOS and Fertility
PCOS is one of the most common causes of infertility, but it is also one of the most treatable. Many women with PCOS conceive with the help of ovulation-inducing medications. Letrozole is now considered the first-line treatment over clomiphene for PCOS-related infertility.
If medication alone does not work, IUI (intrauterine insemination) or IVF (in vitro fertilization) may be the next steps. Arizona has several fertility clinics with experience treating PCOS, including Arizona Reproductive Medicine Specialists and Fertility Treatment Center in Tempe and Scottsdale.
Mental Health and PCOS
Depression and anxiety are significantly more common in women with PCOS. Hormonal imbalances, body image concerns, fertility struggles, and the daily burden of managing a chronic condition all contribute. This is not "all in your head." Your mental health is a medical concern that deserves treatment.
If you are struggling, tell your OB-GYN or primary care provider. Therapy, medication, and support groups can all help. Arizona's AHCCCS program covers behavioral health services.
PCOS Management Checklist
Track your menstrual cycle and symptoms to share with your provider
Ask about bloodwork including androgens, insulin, glucose, and thyroid levels
Discuss whether hormonal birth control or metformin is right for you
Get screened for depression and anxiety at your next visit
Schedule regular check-ups for blood sugar, cholesterol, and blood pressure
Start a consistent exercise routine, even 30 minutes of walking counts
If trying to conceive, ask about letrozole as a first-line fertility treatment
Connect with a PCOS support community for ongoing encouragement

Frequently Asked Questions
Can you have PCOS without cysts on your ovaries?
Yes. The name is misleading. You can be diagnosed with PCOS without polycystic ovaries on ultrasound. The diagnosis requires meeting at least two of three criteria: irregular ovulation, elevated androgens, and polycystic ovaries. Two out of three is enough.
Does PCOS go away after menopause?
Some symptoms like irregular periods naturally resolve, but PCOS is a lifelong condition. Insulin resistance, cardiovascular risk, and metabolic concerns continue after menopause. Ongoing monitoring and healthy habits remain important.
Is PCOS genetic?
There is a strong genetic component. If your mother or sister has PCOS, your risk is higher. Researchers have identified several genes involved, but the condition likely results from a combination of genetic and environmental factors.
Can losing weight cure PCOS?
Weight loss does not cure PCOS, but it can significantly improve symptoms, especially insulin resistance and ovulation. Even a 5 to 10% reduction in body weight can make a noticeable difference. That said, many women with PCOS are at a healthy weight, so weight loss is not always relevant.
Does AHCCCS cover PCOS treatment?
Yes. AHCCCS covers diagnostic testing, medications including birth control and metformin, and specialist visits for PCOS management. Fertility treatments have more limited coverage, so ask your plan about specific benefits.
