Note: Polycystic ovarian syndrome (PCOS) is now called polyendocrine metabolic ovarian syndrome (PMOS). The new name emphasizes the wide-ranging hormonal and metabolic effects linked to the syndrome. The renaming aims to help improve diagnosis, since previously it was thought that the main feature of the condition was ovarian cysts, which do not present in all patients.

What Is PMOS?

Polyendocrine metabolic ovarian syndrome is a common hormonal disorder that affects women of reproductive age. Research published in 2022 indicated that approximately 5% to 15% of women in the reproductive age group worldwide are affected by PMOS. This showcases the high prevalence of this condition.

PMOS is sometimes characterized by enlarged ovaries containing multiple small cysts. That said, various endocrine anomalies and insulin resistance drive this condition. These imbalances disrupt the normal menstrual cycle, leading to health problems such as weight gain and fertility issues.

PMOS has several symptoms, including irregular menstrual cycles, excessive hair growth (hirsutism), acne, and weight gain. It can also lead to complications such as infertility, insulin resistance, type 2 diabetes, high blood pressure, sleep apnea, and an increased risk of heart disease. While it is a chronic condition without a cure, early diagnosis and effective management can help minimize its impact on overall health.

What Are the Causes and Risk Factors for PMOS?

A considerable number of women of childbearing age develop PMOS. However, while the exact cause of PMOS remains elusive, extensive studies suggest a combination of multiple internal and external factors contributing to its development.

Internal Factors

Internal factors such as hormonal imbalances, insulin resistance, obesity, oxidative stress, and inflammation can contribute to the development of PMOS.

Hormonal imbalances

This is one of the leading causes of PMOS, particularly initiated by elevated levels of androgens such as testosterone. In PMOS, the ovaries overproduce androgens, disrupting the normal balance of hormones. This hormonal imbalance can lead to irregular menstrual cycles, the development of ovarian cysts, and other symptoms associated with the condition.

Insulin resistance

Insulin resistance remains closely linked to PMOS as a cause and consequence. Insulin resistance occurs when the body's cells fail to utilize insulin, increasing insulin levels in the blood. This, in turn, triggers the ovaries to produce more androgens. This vicious cycle worsens hormonal imbalances and contributes to the development and progression of PMOS. Weight gain remains the most common manifestation of insulin resistance.

Obesity

Obesity plays a significant role in the onset and progression of PMOS. Adipose tissue produces and releases various hormones and inflammatory substances that further contribute to PMOS development. Inflammation is exacerbated by extra adipose tissue, which also affects hormonal balance and increases insulin resistance.

Recurrent oxidative stress

The imbalance between the body's antioxidant defense system and reactive oxygen species (ROS) generation causes oxidative stress. Due to increased ROS generation and decreased antioxidant capacity, women with PMOS frequently experience greater levels of oxidative stress. Oxidative stress can damage ovarian tissue, disrupt follicular development, and contribute to insulin resistance.

Inflammation

Inflammation is a key component of PMOS and its associated complications. Chronic low-grade inflammation disrupts the delicate hormonal balance, affects ovarian function, and contributes to insulin resistance. Often, women with PMOS present with elevated levels of pro-inflammatory markers.

External factors

External factors, such as genetic mechanisms, dietary intake, physical and emotional stress, and environmental factors, may also lead to the development of PMOS.

Genetic factors

Studies have shown that epigenetic modifications play a crucial role in developing PMOS. Although the fundamental genetic code is unaffected, epigenetic mechanisms entail changes to the DNA structure that affect gene expression.

Over the years, some women with PMOS have shown aberrant DNA methylation patterns and histone modifications. This affects the key genes in hormone regulation, insulin sensitivity, and follicular development. However, the specific genes involved and their interactions remain under investigation.

Dietary intake

Dietary factors play a significant role in PMOS development and progression. Consuming a diet high in sugar, trans fats, added sugar, and processed foods increases the risk of PMOS. Trans fats can lead to insulin resistance, hyperglycemia, and inflammation, all of which are common symptoms of PMOS.

Physical and Emotional Stress

Chronic physical and emotional stress can disrupt the delicate balance of hormones, potentially contributing to PMOS development. Stress triggers the production and release of stress hormones, such as cortisol. This can affect the normal functioning of the hypothalamic-pituitary-ovarian axis, which may lead to hormonal imbalances, irregular menstrual cycles, and the formation of ovarian cysts.

Environmental Factors

Exposure to poisonous environmental substances, such as endocrine-disrupting chemicals (EDCs), may also contribute to developing PMOS. They are commonly found in plastics, pesticides, and personal care products and can mimic or interfere with hormonal signaling pathways. These substances may disrupt normal hormone regulation, leading to PMOS symptoms.

Key Dietary Strategies for Managing PMOS

Diet plays a critical role in managing the symptoms and improving the overall well-being of individuals with PMOS. By adopting appropriate dietary strategies, you can effectively control your insulin levels, manage weight, reduce inflammation, and support hormone regulation. Here are the key strategies:

Focus on Whole, Unprocessed Foods

Choosing whole grains helps maintain steady blood sugar levels and provides sustained energy. These include brown rice, quinoa, and whole wheat bread. Complex carbohydrates, found in legumes, sweet potatoes, and lentils, are fiber-rich. This will aid digestion, promote satiety, and help slow down glucose absorption. Aiming for at least 25 to 30 grams of fiber daily is recommended to support overall metabolic health.

It is advised to consume healthy fats, such as avocados, nuts, seeds, and olive oil, as well as nutritious protein-rich foods without excessive saturated fats, such as skinless poultry, fish, tofu, and lentils. In moderation, they can improve insulin sensitivity, support hormone production, and promote a feeling of fullness.

Consume Specific Nutrients and Supplements for PMOS

Consuming a wide range of colorful fruits, vegetables, and herbs provides abundant antioxidants, vitamins, and phytochemicals. These compounds remain essential for managing PMOS. Vitamin D, magnesium, and chromium are particularly relevant as they help combat oxidative stress and regulate glucose metabolism. Berries, leafy greens, turmeric, and green tea are excellent sources of these antioxidants and phytochemicals.

Furthermore, omega-3 fatty acids in fatty fish (salmon, mackerel), walnuts, and flaxseeds possess anti-inflammatory properties. As a result, they support hormone regulation. You can include these sources of omega-3 in your diet to address the metabolic manifestations of PMOS. This can also alleviate short-term symptoms like menstrual irregularities and acne.

Understand the Glycemic Index/Load

Pay attention to the glycemic index (GI) on food labels. The glycemic index (GI) measures how quickly carbohydrate-containing food raises blood sugar levels. Therefore, understanding the glycemic load provides a more accurate measure of the impact on your blood sugar levels, helping you eat healthily. Low GI diets reduce both total and low-density lipoprotein (LDL) cholesterol, as well as triglycerides, according to research. As a result, they serve to reduce the risk of insulin resistance.

Balance Macronutrients for Insulin Control

The best way to balance macronutrients is by distributing them evenly across meals. You can do this by distributing carbohydrates throughout the day and pairing them with protein and healthy fats. This approach will help prevent rapid blood sugar fluctuations and maintain stable insulin levels.

Implement Strategies for Weight Management

Managing calorie intake and portion sizes is essential for weight management in individuals with PMOS. Eating nutrient-dense, lower-calorie foods and being mindful of portion sizes can help create a calorie deficit, which supports weight loss. Monitoring food intake through tracking or meal planning can be a helpful strategy in this regard.

Pivotal Lifestyle Modifications for PMOS Management

Aside from the dietary modifications mentioned above, certain lifestyle changes can be beneficial. Exercise and stress management comprise the fundamental components of PMOS management. Here are the other vital lifestyle modifications you can adopt for effective PMOS management:

Regular Physical Exercise

Additionally, regular physical activity remains crucial for the long-term management of PMOS symptoms. It increases insulin sensitivity and helps with weight loss. It is also important considering the syndrome affects your endocrine function and metabolism. You can engage in aerobic exercises, strength training, and activities to support your weight loss efforts and improve overall health.

Apply Stress Management Techniques

Practicing mindfulness and meditation techniques can help reduce stress levels. Taking a few minutes daily to engage in deep breathing exercises or following guided meditation can positively impact managing PMOS. Above all, remember that managing stress is an ongoing process. So, it is important to find techniques that work best for you.

Get Adequate and Quality Sleep

Prioritize quality sleep as it plays a vital role in managing stress. You can implement a consistent sleep routine and practice relaxation techniques before bed. To support overall well-being, you should aim for 7 to 8 hours of sleep every night.

Regulate Meal Frequency

Aim for regular meal timings to maintain stable blood sugar levels and prevent excessive calorie intake. Eating smaller, balanced meals throughout the day may be beneficial for managing PMOS symptoms.

Adequate Hydration

Normalize the habit of staying hydrated by drinking sufficient water throughout the day. Proper hydration supports overall health and can help reduce bloating and water retention, which is often experienced by women with PMOS.

Limit Caffeine and Alcohol Intake

Excessive caffeinated beverages and alcohol intake can disrupt your hormone levels and affect sleep quality. Instead, you can opt for herbal teas, water, or other non-caffeinated and non-alcoholic alternatives.

Why Seek Professional Support for PMOS Management
