PCOS: Diagnosis, Treatment, Dietary Changes and Fitness

PCOS, or Polycystic Ovary Syndrome, is a common hormonal disorder that affects women of reproductive age. It is characterized by an imbalance in sex hormones, particularly an excess of androgens (male hormones), which can disrupt the normal function of the ovaries.

The exact cause of PCOS is not fully understood, but it is believed to involve a combination of genetic and environmental factors. Insulin resistance, a condition in which the body’s cells do not respond properly to insulin, is also often associated with PCOS.

The primary features of PCOS include:

  • Menstrual Irregularities: Women with PCOS may experience irregular menstrual cycles, including infrequent periods or prolonged periods of absence.
  • Excess Androgen Levels: Elevated levels of androgens can lead to symptoms such as acne, excessive hair growth (hirsutism), and male-pattern baldness.
  • Ovarian Cysts: Despite the name, not all women with PCOS have cysts on their ovaries. However, the condition is characterized by the presence of small cysts or follicles on the ovaries, which are seen during an ultrasound examination.

In addition to these primary features, PCOS is often associated with other health concerns, including insulin resistance, weight gain or obesity, infertility or difficulty getting pregnant, and an increased risk of developing conditions such as type 2 diabetes, high blood pressure, and cardiovascular disease.


The diagnosis of PCOS involves a combination of medical history assessment, physical examination, blood tests, and ultrasound imaging. The following steps are typically involved in diagnosing PCOS:

  • Medical History Assessment: Your healthcare provider will begin by discussing your medical history, including your menstrual cycles, symptoms (such as irregular periods or excessive hair growth), and any other relevant health concerns. They may also inquire about your family history of PCOS or other hormonal disorders.
  • Physical Examination: A physical examination will be conducted to assess signs of PCOS, such as excessive hair growth (hirsutism), acne, and weight gain. Your healthcare provider may also check for any other physical indications of hormonal imbalances.
  • Blood Tests: Blood tests are used to measure hormone levels and rule out other potential causes of your symptoms. The specific hormones that are typically evaluated include:
    • Androgens: Testosterone and other androgen levels are checked to determine if there is an excess present, which is common in PCOS.
    • Sex Hormone Binding Globulin (SHBG): This protein binds to androgens and regulates their activity. Low levels of SHBG are often observed in women with PCOS.
    • Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH): The balance between FSH and LH is disrupted in PCOS. LH levels are typically higher than FSH levels.
    • Insulin and Glucose: Insulin resistance is frequently associated with PCOS. Blood tests can assess fasting insulin and glucose levels to evaluate insulin sensitivity.
  • Pelvic Ultrasound: An ultrasound examination of the pelvis is conducted to evaluate the ovaries for the presence of cysts or follicles. However, it’s important to note that not all women with PCOS will have cysts, and the diagnosis is not solely based on ultrasound findings.

The diagnosis of PCOS is typically made if you meet specific criteria, which may vary slightly depending on the guidelines followed by your healthcare provider or country. The most widely used criteria for diagnosis are those established by the Rotterdam criteria, which require the presence of at least two out of three features: irregular periods, signs of excess androgens, and polycystic ovaries observed on ultrasound.


The treatment for PCOS aims to manage symptoms, address underlying hormonal imbalances, and reduce the risk of long-term complications. The specific treatment approach may vary depending on your individual symptoms, reproductive goals, and overall health. Here are some common treatment options for PCOS:

  1. Lifestyle Modifications: Making healthy lifestyle changes can have a significant impact on managing PCOS. These changes may include:
    • Regular Exercise: Engaging in regular physical activity helps improve insulin sensitivity, manage weight, and regulate hormone levels.
    • Healthy Diet: Adopting a balanced and nutritious diet can help manage weight, reduce insulin resistance, and improve overall hormonal balance. Focus on whole foods, lean proteins, fiber-rich foods, and low-glycemic index carbohydrates. Limit the intake of processed foods, sugary drinks, and refined carbohydrates.
    • Weight Management: If you are overweight or obese, losing weight through a combination of diet and exercise can help improve PCOS symptoms, regulate menstrual cycles, and enhance fertility.
  2. Medications: Depending on your specific symptoms and goals, your healthcare provider may prescribe medications to address hormonal imbalances and manage PCOS symptoms. These may include:
    • Oral Contraceptives: Birth control pills containing both estrogen and progestin can help regulate menstrual cycles, reduce androgen levels, and manage symptoms such as acne and excessive hair growth.
    • Anti-Androgen Medications: These medications block the effects of androgens and can help reduce symptoms like hirsutism and hair loss.
    • Insulin-Sensitizing Medications: Medications such as metformin are often prescribed to improve insulin sensitivity and help manage symptoms of insulin resistance.
    • Fertility Medications: If you are trying to conceive, your healthcare provider may prescribe medications to stimulate ovulation, such as clomiphene citrate or letrozole.
  3. Assisted Reproductive Technology (ART): In cases where fertility is a concern and medication alone is not effective, procedures such as in vitro fertilization (IVF) or intrauterine insemination (IUI) may be recommended.
  4. Psychological Support: PCOS can have a significant emotional and psychological impact. Seeking support from therapists, support groups, or counselors can help cope with the emotional challenges associated with PCOS.

It’s important to work closely with a healthcare provider experienced in treating PCOS to develop an individualized treatment plan based on your specific needs and goals.

Dietary Changes

Dietary changes can play a crucial role in managing PCOS symptoms and improving overall health. Here are some dietary recommendations that may be beneficial for women with PCOS:

  • Focus on Whole Foods: Emphasize whole, unprocessed foods in your diet. Include plenty of fruits, vegetables, whole grains, lean proteins, and healthy fats. These foods provide essential nutrients and help maintain stable blood sugar levels.
  • Choose Low-Glycemic Index (GI) Carbohydrates: Opt for carbohydrates that have a lower glycemic index, as they have a slower and more gradual impact on blood sugar levels. Examples include whole grains, legumes, and non-starchy vegetables. Limit or avoid high-GI foods such as white bread, white rice, sugary drinks, and processed snacks.
  • Balanced Macronutrients: Ensure that your meals contain a balance of macronutrients—carbohydrates, proteins, and fats. This balance helps promote satiety, stabilize blood sugar levels, and regulate hormone production. Include lean proteins like chicken, fish, tofu, or legumes in each meal.
  • Healthy Fats: Incorporate healthy fats into your diet, such as avocados, nuts, seeds, olive oil, and fatty fish like salmon. These fats support hormone production and help keep you feeling satisfied.
  • Limit Added Sugars: Minimize the consumption of added sugars, as they can lead to spikes in blood sugar levels and contribute to weight gain. Be cautious of hidden sources of added sugars in processed foods and beverages.
  • Adequate Fiber Intake: Include fiber-rich foods in your diet, such as whole grains, fruits, vegetables, and legumes. Fiber promotes healthy digestion, helps regulate blood sugar levels, and aids in weight management.
  • Portion Control: Pay attention to portion sizes to avoid overeating and promote weight management. Use smaller plates and practice mindful eating, focusing on hunger and fullness cues.
  • Stay Hydrated: Drink plenty of water throughout the day to support overall health and hydration. Limit sugary beverages and opt for water, herbal teas, or infused water instead.
  • Be Mindful of Caffeine and Alcohol: Moderate your intake of caffeine and alcohol, as they can impact hormone levels and overall health. Opt for herbal teas or decaffeinated beverages and consume alcohol in moderation, if at all.

Foods To Be Avoided

While there is no specific “PCOS diet” or a definitive list of foods to be avoided for all women with PCOS, some individuals may find that certain foods worsen their symptoms. Here are some general recommendations on foods that some women with PCOS may consider limiting or avoiding:

  • Highly Processed Foods: Processed foods are often high in added sugars, unhealthy fats, and artificial ingredients. These include sugary snacks, packaged desserts, fast food, and processed meats. They provide little nutritional value and can contribute to weight gain and insulin resistance.
  • Sugary Foods and Beverages: Foods and drinks high in added sugars can cause rapid spikes in blood sugar levels and contribute to weight gain. Limit or avoid sugary sodas, fruit juices, candy, pastries, and sweetened snacks.
  • High-Glycemic Index (GI) Carbohydrates: Foods with a high glycemic index can cause rapid increases in blood sugar levels. These include refined grains like white bread, white rice, and sugary cereals. Instead, choose whole grains and low-GI carbohydrates like whole wheat bread, brown rice, quinoa, and sweet potatoes.
  • Saturated and Trans Fats: Limit your intake of foods high in saturated fats, such as fatty meats, full-fat dairy products, and fried foods. Trans fats, commonly found in processed snacks, baked goods, and margarine, should be avoided as well.
  • Excessive Caffeine: While moderate caffeine intake is generally considered safe, some women with PCOS may find that high caffeine consumption exacerbates their symptoms. Be mindful of your caffeine intake from coffee, tea, energy drinks, and chocolate and adjust according to your own tolerance.
  • Alcohol: Alcohol consumption should be moderate or avoided, as it can affect hormone balance, liver function, and overall health. Excessive alcohol intake can also contribute to weight gain.

It’s important to note that dietary needs and sensitivities may vary among individuals with PCOS. Some foods that may worsen symptoms for one person may not have the same effect on others. It is advisable to listen to your body, track how certain foods make you feel, and work with a registered dietitian or nutritionist specializing in PCOS to determine a personalized approach to your diet.

Remember, individualized dietary guidance is important as it considers your specific needs, goals, and any underlying health conditions you may have.

Fitness Routines for Hormonal Balance

Engaging in regular physical activity and incorporating specific types of exercise into your fitness routine can help promote hormonal balance in women with PCOS. Here are some fitness recommendations that may be beneficial:

  • Cardiovascular Exercise: Aerobic activities such as brisk walking, jogging, cycling, swimming, dancing, or aerobic classes can help improve insulin sensitivity, manage weight, and boost overall cardiovascular health. Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, or 75 minutes of vigorous-intensity exercise if you can tolerate it.
  • High-Intensity Interval Training (HIIT): HIIT involves short bursts of intense exercise followed by periods of active recovery. This type of workout has been shown to improve insulin sensitivity, promote fat burning, and enhance cardiovascular fitness. Consult with a fitness professional to design a safe and suitable HIIT routine for your fitness level and health condition.
  • Strength Training: Incorporating strength training exercises into your routine can help build lean muscle mass, increase metabolism, and improve insulin sensitivity. Focus on compound exercises that target multiple muscle groups, such as squats, lunges, deadlifts, push-ups, and rows. Start with lighter weights or bodyweight exercises and gradually progress over time. Aim for two to three strength training sessions per week, allowing for adequate rest and recovery between sessions.
  • Yoga and Pilates: Practicing yoga or Pilates can help reduce stress levels, improve flexibility, and promote mind-body relaxation. These activities may also contribute to better hormone regulation. Look for classes or online resources that offer yoga or Pilates specifically designed for PCOS or hormonal balance.
  • Mindful Movement: Engaging in activities that promote mindfulness and stress reduction can have positive effects on hormonal balance. Consider incorporating activities such as tai chi, qigong, meditation, or gentle stretching routines into your fitness regimen.
  • Regularity and Consistency: Consistency is key when it comes to maintaining a fitness routine for hormonal balance. Aim for regular exercise sessions, ideally spread throughout the week, to achieve maximum benefits.

Before starting any new fitness routine, it’s important to consult with your healthcare provider, especially if you have any underlying health conditions or concerns. Additionally, working with a certified fitness professional or personal trainer who has experience working with women with PCOS can provide guidance, personalized exercise plans, and ensure proper form and technique.

Remember to listen to your body, start slowly if you’re new to exercise, and gradually increase intensity and duration over time. Be patient with yourself and focus on sustainable, long-term habits rather than quick fixes.
