Non-Diabetics Can Improve Blood Sugar Control with a CGM for Better Health
How to Use a Continuous Glucose Monitor (CGM) for Optimal Blood Sugar
Blood sugar, or the amount of glucose in one’s blood, plays a crucial role in nearly every aspect of our body’s functioning. As the primary source of energy for our cells, glucose affects everything from our brain function and mood to our physical energy levels and long-term health outcomes.
So, regulating blood sugar is essential for overall health and well-being in everyone – not just diabetics!
Dr. Ruthie Harper is a renowned functional medicine doctor in Austin, TX who is at the forefront of using advanced technology to optimize health. One such tool she frequently recommends to her patients is the Continuous Glucose Monitor (CGM) – for monitoring blood sugar levels to optimize health, even for individuals without diabetes.
In this comprehensive guide, Dr. Harper explores the use of CGMs, defines target glucose ranges based on research, and provides steps for maintaining optimal blood sugar levels – so you can not only feel better now, but help prevent disease, and live with vitality for decades to come.
Why Blood Sugar Matters for Non-Diabetics
When blood sugar levels are well-controlled, our bodies operate efficiently, maintaining stable energy, clear cognition, and balanced hormones. However, when blood sugar fluctuates excessively or remains consistently high, it can lead to a cascade of negative effects throughout the body, even in individuals without diabetes.
Chronic high blood sugar can damage blood vessels, nerves, and organs, potentially leading to complications such as cardiovascular disease, kidney problems, and impaired vision. It can also contribute to inflammation, oxidative stress, and accelerated aging. Moreover, poor blood sugar control can affect weight management, mood stability, and sleep quality.
By maintaining stable blood sugar levels through diet, exercise, and lifestyle choices, everyone – not just those with diabetes – can optimize their health, reduce the risk of chronic diseases, and enhance their overall quality of life. This is why understanding and managing blood sugar is a fundamental aspect of preventive health care and longevity.
Dr. Ruthie Harper explains that while finding clear guidelines for what constitutes “normal” or “optimal” glucose levels can be challenging, CGMs provide valuable insights that can help individuals make informed decisions about their health. At her practice in Austin, she guides patients on how to use CGMs to gain a more detailed and dynamic understanding of their glucose fluctuations throughout the day.
What is a Continuous Glucose Monitor (CGM)?
A Continuous Glucose Monitor – usually called a CGM – is a small, wearable device that continuously tracks glucose levels in the interstitial fluid, which is the fluid between cells. Unlike traditional blood glucose tests like “finger sticks” that only capture glucose levels at specific moments, CGMs provide real-time data on glucose trends. This continuous monitoring, offers a 24-hour profile of glucose levels, giving insights into glycemic variability, fasting glucose levels, post-meal glucose spikes, and overnight trends.
This data can be incredibly valuable for optimizing diet, exercise, and lifestyle habits to improve metabolic health. Well managed, stable blood sugar levels are crucial for maintaining energy balance, cognitive function, and overall metabolic health. However, frequent spikes and dips in glucose levels, even within the normal range, can lead to inflammation, weight gain, insulin resistance, and increased risk for conditions like cardiovascular disease, type 2 diabetes, Alzheimer’s disease, and more.
What are “Normal” Glucose Levels?
As a functional medicine doctor in Austin, TX, Dr. Ruthie Harper stresses the importance of understanding one’s glucose levels. Finding clear guidelines for what constitutes “normal” or “optimal” glucose levels can be challenging, but CGMs provide valuable insights that can help individuals make informed decisions about their own blood sugar levels and fluctuations.
According to the American Diabetes Association (ADA), normal fasting glucose levels for a nondiabetic person should be below 100 mg/dL, while post-meal glucose should not exceed 140 mg/dL. However, Dr. Harper points out that continuous glucose monitoring offers more detailed data than these one-time measures.
Below, Austin, TX functional medicine doctor Ruthie Harper, MD guides you through a step-by-step process to use a continuous glucose monitor for effectively for optimal glucose control.
Step-by-Step Guide to Using a Continuous Glucose Monitor for Optimal Blood Sugar
Step 1: Set Up Your Continuous Glucose Monitor
We will provide you with a prescription for your CGM. The device consists of a sensor, typically inserted just under the skin, and a transmitter that sends glucose readings to your smartphone or monitoring device.
Once the CGM is installed, you can start tracking your glucose levels throughout the day and night.
Step 2: Understand Your Baseline Glucose Levels with a CGM
After wearing the CGM for a few days, you will review your data to understand your baseline glucose levels. Key points to focus on include:
• Fasting Glucose: This is your glucose level after not eating for at least 8 hours. Optimal fasting glucose for most people falls in the 90mg/dL range or below.
•Post-Meal Glucose Peaks: These are the highest glucose levels observed within 1-2 hours after eating. Aim for post-meal glucose peaks below 140 mg/dL which falls back to your baseline 90mg/dL within 90 minutes post meal.
Step 3: Set Your Glucose Targets on Your Phone
One of the most convenient aspects of the CGM is that it can be managed on your smartphone – without the need for a separate device!
Target glucose levels for continuous glucose monitor (CGM) usage are personalized ranges that individuals aim to maintain for optimal health. These targets can vary based on individual factors such as age, overall health, and specific health goals.
Dr. Harper or your personal doctor will work with you to establish your personal glucose target ranges, which help them make informed decisions about diet, exercise, and lifestyle to maintain stable blood sugar levels and promote long-term health.
Step 4: Monitor Post-Meal Glucose Responses
One of the most valuable insights from using a CGM is how your body responds to different foods. For example:
• Carbohydrate-heavy meals tend to spike glucose levels more than meals high in fiber, protein, and healthy fats.
• High-glycemic index foods like white bread and sugary snacks can cause rapid glucose spikes followed by sharp drops (reactive hypoglycemia), which may lead to fatigue.
• Foods high in fiber, however, or foods containing “healthy” fats can slow the absorption of glucose into the blood and keep blood glucose levels more stable.
Using your CGM continuous glucose monitor, you can experiment with different types of meals, combine different “macronutrients” together during meals (carbohydrate, fat and protein), and track your glucose responses.
By keeping track of what you eat and its effect on your blood glucose readings on your CGM, you can learn to avoid significant glucose spikes and dips.
Step 5: Adjust Your Diet & Lifestyle Based on CGM Readings
Based on your CGM data, the next step is to make adjustments to your diet and lifestyle to keep your glucose levels stable.
Here are some tips for making adjustments that avoid significant glucose spikes and dips:
• Choose Low-Glycemic Foods: Focus on low glycemic fruits and vegetables, whole grains, vegetables, and legumes, which have a gentler effect on blood glucose and combine carbohydrates with protein to balance blood sugar effects.
• Increase Fiber Intake: Fiber slows down glucose absorption and helps prevent spikes.
• Exercise Regularly: Physical activity helps improve insulin sensitivity, which can lower your glucose levels after meals.
• Time Your Meals Wisely: Avoid late-night eating, which can lead to higher nighttime glucose levels.
Step 6: Track Trends with your CGM & Make Continuous Adjustments
Remember, glucose levels fluctuate due to a variety of factors in addition to diet, including sleep, stress, and exercise. Over time, your CGM data will help you identify trends in your glucose levels and adjust your diet and lifestyle accordingly.
• Nighttime Glucose Levels: If you notice higher glucose levels at night, consider avoiding late meals and increasing physical activity during the day.
• Post-Meal Spikes: If you frequently experience post-meal spikes above 140 mg/dL, experiment with lowering your carbohydrate intake and increasing protein and fat to stabilize glucose levels.
Step 7: Share Your CGM Data with Your Healthcare Provider
Regularly review your CGM data with Dr. Harper or your healthcare provider, to discuss trends, make adjustments, and ensure you’re on track with your health goals. Always consult with your doctor to ensure that your glucose targets and strategies are appropriate for your specific needs.
With improved blood sugar management, many patients may begin to see reduced belly fat, less fatigue after meals, weight loss, less sugar cravings, and even an improved sex drive. Blood sugar management can also lower high triglycerides & improve low HDL cholesterol in some individuals.
