Polycystic Ovary Syndrome
What is Polycystic Ovary Syndrome?
Polycystic Ovary Syndrome, or PCOS, is a hormonal disorder that affects 1 in 10 women of reproductive age. It causes the ovaries to produce higher levels of androgens, which are male hormones that women normally have in small amounts. This hormonal imbalance can lead to enlarged ovaries with small fluid-filled sacs, called cysts, on the outer edges.
PCOS affects more than just your ovaries. It impacts your metabolism, fertility, and long-term health. Women with PCOS often struggle with insulin resistance, which means their bodies have trouble using insulin properly. This can lead to weight gain, difficulty losing weight, and an increased risk of type 2 diabetes.
The condition shows up differently in each woman. Some experience irregular periods and fertility challenges, while others deal with unwanted hair growth or acne. Early detection and lifestyle changes can help manage symptoms and reduce long-term health risks. Understanding your hormone levels through blood testing is the first step toward taking care of your health.
Symptoms
- Irregular or absent menstrual periods, often fewer than 8 periods per year
- Excess hair growth on face, chest, back, or other areas where men typically grow hair
- Acne or oily skin, especially on the face, chest, and upper back
- Thinning hair or hair loss on the scalp, similar to male-pattern baldness
- Weight gain or difficulty losing weight, particularly around the midsection
- Dark patches of skin in body creases like the neck, groin, or under breasts
- Skin tags in the armpits or neck area
- Difficulty getting pregnant or infertility due to irregular ovulation
Some women have mild symptoms and may not realize they have PCOS for years. Others experience multiple symptoms that significantly affect their quality of life. Many women discover they have PCOS when they have trouble getting pregnant.

Causes and risk factors
The exact cause of PCOS is not fully understood, but several factors play a role. Insulin resistance is a major contributor, affecting up to 70% of women with PCOS. When your body resists insulin, your pancreas makes more insulin to compensate. High insulin levels trigger your ovaries to produce more androgens, which interfere with ovulation and cause many PCOS symptoms.
Genetics also matter. If your mother or sister has PCOS, your risk increases. Inflammation in the body may contribute to elevated androgen production as well. Excess weight can worsen PCOS symptoms by increasing insulin resistance, but women at any weight can develop this condition. Hormonal imbalances involving pregnenolone, a precursor to androgens, can indicate disrupted hormone production pathways that contribute to PCOS.
How it's diagnosed
Doctors diagnose PCOS by looking at your symptoms, medical history, and blood test results. There is no single test for PCOS. Most doctors use the Rotterdam criteria, which requires at least 2 of 3 findings: irregular periods, signs of high androgens like excess hair growth or elevated hormone levels, and polycystic ovaries seen on ultrasound.
Blood tests play a key role in diagnosis and monitoring. Testing hormone levels like pregnenolone helps identify the hormonal imbalances driving PCOS symptoms. Rite Aid offers hormone testing through our preventive health service, making it easy to track your levels at Quest Diagnostics locations nationwide. Your doctor may also check insulin, glucose, and cholesterol levels to assess related health risks.
Treatment options
- Adopt a balanced diet focused on whole foods, lean proteins, and fiber-rich vegetables to improve insulin sensitivity
- Reduce refined carbohydrates and added sugars, which can spike insulin levels
- Exercise regularly, aiming for at least 150 minutes of moderate activity per week
- Achieve and maintain a healthy weight, as even a 5% to 10% weight loss can improve symptoms
- Consider anti-inflammatory foods like fatty fish, nuts, and leafy greens
- Metformin, a medication that improves insulin sensitivity and may help regulate periods
- Birth control pills to regulate menstrual cycles and reduce androgen levels
- Anti-androgen medications like spironolactone to reduce excess hair growth and acne
- Fertility medications if you are trying to conceive
- Work with a healthcare provider to develop a personalized treatment plan based on your symptoms and goals

Frequently asked questions
The first signs often include irregular or missed periods, usually starting in the teenage years or early twenties. Many women also notice acne, excess hair growth on the face or body, or difficulty losing weight. Some women have no obvious symptoms until they try to get pregnant. Early symptoms can be subtle and easily mistaken for other conditions.
PCOS is a lifelong condition that does not go away on its own. However, symptoms can be managed effectively through lifestyle changes and medical treatment. Some women find their symptoms improve with weight loss, diet changes, and regular exercise. After menopause, some PCOS symptoms may naturally decrease, but metabolic risks like diabetes and heart disease remain important to monitor.
Blood tests measure hormone levels to identify the imbalances characteristic of PCOS. Doctors typically check androgens, pregnenolone, and other hormone precursors that may be elevated. Tests may also check insulin, glucose, and cholesterol levels to assess metabolic health. No single blood test confirms PCOS, so results are evaluated alongside symptoms and sometimes ultrasound findings.
Yes, many women with PCOS can get pregnant with the right treatment. PCOS is a leading cause of infertility, but it is treatable. Lifestyle changes, weight loss, and medications like metformin or fertility drugs can help restore ovulation. Some women may need additional fertility treatments, but most women with PCOS can conceive with appropriate medical support.
Limit refined carbohydrates like white bread, pasta, and pastries that spike blood sugar and insulin. Reduce added sugars found in sodas, sweets, and processed foods. Minimize inflammatory foods like fried foods and excessive red meat. Focus instead on whole grains, lean proteins, vegetables, and healthy fats to support insulin sensitivity and hormone balance.
Yes, PCOS increases your risk for several long-term health conditions. Women with PCOS have higher rates of type 2 diabetes, high blood pressure, and heart disease. The condition also raises the risk of endometrial cancer due to irregular periods and prolonged exposure to estrogen without progesterone. Sleep apnea, fatty liver disease, and depression are also more common in women with PCOS.
Most doctors recommend blood tests at least once a year to monitor hormone levels, blood sugar, and cholesterol. If you are starting new medications or making significant lifestyle changes, you may need more frequent testing every 3 to 6 months. Regular testing helps track your progress and catch potential health problems early. Your doctor will create a testing schedule based on your individual needs.
Exercise is one of the most effective ways to manage PCOS symptoms. Regular physical activity improves insulin sensitivity, helps with weight management, and may help regulate periods. Aim for at least 150 minutes of moderate activity per week, combining cardio and strength training. Even small amounts of daily movement can make a meaningful difference in your symptoms and long-term health.
Not exactly. Despite the name, you can have PCOS without having cysts on your ovaries. The condition is primarily a hormonal and metabolic disorder. The small cysts that may appear on ultrasound are actually follicles that did not mature and release eggs due to hormonal imbalances. Many women with cysts on their ovaries do not have PCOS, and some women with PCOS have no visible cysts.
Weight loss does not cure PCOS, but it can significantly improve symptoms and reduce health risks. Even losing 5% to 10% of your body weight can help regulate periods, improve insulin sensitivity, and reduce androgen levels. Many women find their symptoms become much more manageable with weight loss. However, women at healthy weights can also have PCOS and benefit from other treatments like medication and lifestyle changes.
