Endocrine Disrupting Chemicals and PCOS

Polycystic Ovary Syndrome (PCOS) affects many women, influencing hormone levels, metabolism, and overall health. One crucial yet often overlooked factor in managing PCOS is our exposure to endocrine-disrupting chemicals (EDCs), which can significantly impact hormone health, glucose metabolism, insulin sensitivity, and body fat distribution.

What Are EDCs?

EDCs are substances that interfere with hormonal functions in our bodies. They can mimic, block, or disrupt natural hormones, leading to a range of health issues.

Common sources of EDCs include personal care products, food packaging, and household items. For many women, daily exposure to these chemicals begins in the bathroom, where a collection of products—like deodorants, shampoos, soaps, and fragrances are hiding harmful ingredients.

Common Types of EDCs

1. Phthalates: Found in many fragrances, shampoos, and lotions, these chemicals can disrupt endocrine function and are linked to reproductive issues.

2. Bisphenol A (BPA): Commonly used in plastics and food containers, BPA is known to affect insulin sensitivity and hormone regulation.

3. Parabens: Often found in cosmetics and personal care products, parabens can mimic estrogen and disrupt hormonal balance.

4. Aluminium: Present in antiperspirants, aluminium acts as a xenoestrogen, potentially increasing oestrogenic activity in sensitive tissues.

5. Triclosan: Found in some soaps and toothpaste, this chemical can disrupt thyroid hormones and contribute to antibiotic resistance.

6. Synthetic Fragrances: These can contain up to 100 different chemicals, many of which are harmful to hormone health.

7. Sodium Lauryl Sulfate (SLS): Commonly used in shampoos and cleansers, SLS can strip natural oils from the skin and allow toxic chemicals to enter the bloodstream.

The Impact of EDCs on Hormones

For women with PCOS, hormone health is paramount. EDCs can significantly affect the delicate balance of hormones like oestrogen, progesterone, and testosterone. Many personal care products contain synthetic fragrances, which can disrupt endocrine function and contribute to hormonal imbalances that are already happening in PCOS.

Additionally, aluminium in antiperspirants acts as a xenoestrogen, potentially plugging sweat glands and leading to increased oestrogenic activity in sensitive breast tissue. For anyone with breast cancer risks and family history, it’s essential to scrutinise ingredient lists when choosing personal care products.

EDCs, Insulin Resistance, and Glucose Metabolism

Research indicates that EDCs can negatively impact insulin sensitivity, a critical aspect of managing PCOS. Chemicals such as phthalates and BPA are known to disrupt insulin signaling, which can exacerbate the insulin resistance commonly seen in women with PCOS. This resistance not only affects weight management but can also lead to difficulties in regulating blood sugar levels.

Increased insulin levels can trigger higher testosterone production, worsening symptoms like hirsutism (excess hair growth), acne, and irregular periods. These hormonal imbalances can contribute to unwanted body fat distribution, often leading to increased abdominal fat—a common concern for many women with PCOS.

Fat Distribution and Body Composition

EDCs are also linked to altered body fat distribution. Women with PCOS often experience an accumulation of visceral fat, which is associated with increased risks of metabolic syndrome, type 2 diabetes, and cardiovascular disease. This fat distribution is further compounded by EDC exposure, making it crucial to be aware of what’s in our products.

Practical Steps for Minimizing EDC Exposure

1. Choose Natural Alternatives: Opt for personal care products that are free from synthetic fragrances, phthalates, and parabens. Look for organic, fragrance-free options whenever possible.

2. Ditch the Plastic: Reduce your exposure to BPA by using glass or stainless steel containers instead of plastic. Avoid microwaving food in plastic containers.

3. Mind Your Menstrual Products: Use organic cotton pads and tampons, or consider switching to a menstrual cup to reduce exposure to EDCs found in conventional products.

4. Educate Yourself: Stay informed about the ingredients in your personal care products. Knowing what to look for can empower you to make safer choices.

5. DIY Spa Days: Incorporate simple, natural ingredients into your skincare routine, such as coffee body scrubs, honey, and aloe vera. These can nourish your skin without the harmful side effects of commercial products.
