Polycystic Ovary Syndrome (PCOS) is a common condition affecting up to 1 in 8 women of reproductive age. Among its various symptoms, insulin resistance can influence both the development and management of PCOS. In this blog post I hope to help you understand what insulin resistance is, why it matters in PCOS and what lifestyle changes you can make to better manage your health.
What is Insulin Resistance?
Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels by allowing glucose from the bloodstream to enter cells, where it is used for energy. Think of insulin like a key that unlocks a cell letting glucose in. Insulin resistance occurs when the body's cells become less responsive to insulin, leading to higher levels of insulin in the blood as the body tries to compensate. Essentially, the key is not able to unlock the cells and let the glucose in. Over time, this can cause elevated blood sugar levels and an increased risk of developing type 2 diabetes.
Insulin Resistance and PCOS: What's the Connection?
Up to 70% of people with PCOS have insulin resistance. In the context of PCOS, insulin resistance not only contributes to weight gain (particularly around the abdomen) but also plays a significant role in increasing androgen (male hormone) production, which can worsen symptoms like irregular periods acne, and excess hair growth.
Insulin resistance can create a vicious cycle in PCOS. Higher insulin levels prompt the ovaries to produce more androgens, which can then exacerbate insulin resistance further. Breaking this cycle is key to managing PCOS effectively.
Lifestyle Strategies to Manage Insulin Resistance in PCOS
1. Adopt a Balanced Diet:
Focus on Low-Glycemic Index (GI) Foods: These foods cause a slower and more gradual rise in blood sugar levels. Incorporate whole grains (like oats and quinoa), legumes and plenty of non-starchy vegetables.
Include Healthy Fats: Fats from sources like avocados, nuts, seeds, and olive oil can help improve insulin sensitivity.
Prioritize Protein: Protein-rich foods like lean meats, fish, eggs, tofu, and legumes can help stabilize blood sugar levels and reduce cravings.
2. Engage in Regular Physical Activity:
Incorporate Both Cardio and Strength Training: Aerobic exercises (like walking, running, or cycling) and resistance exercises (like weight lifting or body-weight exercises) are both effective at improving insulin sensitivity.
Aim for Consistency Over Intensity: Even moderate activities, such as brisk walking for 30 minutes most days of the week, can improve insulin resistance.
3. Manage Stress:
Practice Relaxation Techniques: Mindfulness, meditation, deep breathing exercises and yoga can help lower cortisol levels, which in turn can help regulate insulin sensitivity.
Ensure Adequate Sleep: Poor sleep can increase insulin resistance. Aim for 7-9 hours of quality sleep per night and try to maintain a consistent sleep schedule.
4. Monitor Blood Sugar Levels:
Keeping track of blood sugar levels through regular checks with your doctor can help you understand how your body is responding to dietary changes and physical activity. This can provide valuable insights to fine-tune your lifestyle interventions.
The Bottom Line
Managing insulin resistance is a cornerstone of effective PCOS management. While there is no one-size-fits-all solution, adopting a healthy diet, engaging in regular exercise and managing stress can help improve insulin sensitivity and alleviate many PCOS symptoms.
Remember, small, consistent changes over time can lead to significant improvements in your health and well-being. It's essential to find a balanced approach that works for you and seek support from a healthcare professional who understands your individual needs.
