How cgms support hormonal balance and blood sugar control

Continuous Glucose Monitors (CGMs) are wearable devices that track your blood sugar levels in real-time. They can help you understand how diet, exercise, stress, and sleep affect your glucose—and how these factors tie into your hormonal health. Here's what you need to know:

Why It Matters: Blood sugar fluctuations impact hormones like insulin, cortisol, oestrogen, and progesterone. Stabilising glucose can help manage conditions like PCOS, menopause symptoms, or irregular cycles.

How CGMs Help: Track glucose patterns to adjust meals, workouts, and daily habits for better hormonal balance.

Key Tips:

• Spot glucose spikes after meals and swap foods accordingly (e.g., replace a bagel with eggs for breakfast).
• Align exercise with glucose stability: High-intensity workouts during stable times, low-intensity during stress.
• Use CGM data to monitor stress and sleep-related glucose trends.

‍Tools to Pair: Combine CGMs with apps like Flo for cycle tracking, Oura for sleep, and mindfulness apps to reduce stress.CGMs empower you to make smarter decisions about your health by connecting glucose data to hormonal patterns.

The connection between blood sugar and hormones

Blood sugar and hormones are closely linked, each influencing the other in significant ways. Grasping this relationship can help you make the most of your CGM to support hormonal balance.

Hormones and blood sugar regulation

Hormones play a key role in managing blood sugar levels. Insulin helps your body absorb glucose, while cortisol raises blood sugar during stress. Oestrogen boosts insulin sensitivity, but progesterone has the opposite effect, often leading to fluctuations. This is why oestrogen and progesterone shifts can cause blood sugar changes during the menstrual cycle.

Blood sugar's impact on hormonal imbalances

Unstable blood sugar levels can disrupt hormonal balance, making conditions like PCOS and menopause worse. For instance, PCOS is aggravated by insulin resistance, which raises androgen levels.

The ZOE PREDICT study also found that hormonal changes after menopause increase fasting glucose levels and lower insulin sensitivity. Stress adds another layer: cortisol triggers the liver to produce more glucose, which can throw off the balance between oestrogen and progesterone.

Using CGM data can help you spot patterns and make smarter decisions about your diet, exercise, and daily habits to manage these hormonal shifts. By tracking blood sugar fluctuations, CGMs offer a clearer picture of how your body responds to hormonal changes, empowering you to take action.

Starting with a cgm for hormonal health

A CGM gives you real-time insights into your blood sugar, helping you make smarter choices for better hormonal balance.

How cgms work and their use

A Continuous Glucose Monitor (CGM) is a small device placed on your skin that tracks your blood glucose levels around the clock. It uses a tiny sensor inserted under the skin to measure glucose in your interstitial fluid and automatically sends this data to your smartphone or a dedicated receiver.

Here’s what makes up a CGM:

• Sensor: Inserted under the skin to measure glucose levels.
• Transmitter: Sends the glucose data to your device.
• Receiver or App: Displays your readings in real time.

Choosing the right CGM is key to getting the most out of it for monitoring your hormonal health.

Choosing a CGM device

When picking a CGM, look for features that match your needs. Here are a few to consider:

For example, Vively offers a CGM program starting at $249 for a 3-month plan. This includes one sensor and personalised insights to help you understand your data better.

Once you’ve picked your CGM, the next step is learning how to interpret the data it provides.

Reading CGM data for hormonal insights

Interpreting your CGM data means spotting trends in your glucose levels and linking them to hormonal changes. This information can guide adjustments to your diet and lifestyle.

Some key metrics to pay attention to are fasting glucose levels, post-meal responses, daily glucose curves, and overnight trends. Pay close attention to how your glucose levels shift during different phases of your menstrual cycle or menopause. These patterns can reveal how your hormones are affecting your glucose and help you make targeted changes to improve balance.

Strategies for hormonal balance using CGM data

Here are a few strategies you can use to maximise the use of CGM, not just for your hormones but overall metabolic health.

Adjusting your diet with CGM insights

Your CGM (Continuous Glucose Monitor) gives you real-time feedback on how your body reacts to different foods. This data can guide you in making smarter dietary decisions to support hormonal health.

Here’s how to use CGM data to fine-tune your meals:

For example, if you notice a glucose spike after eating a bagel for breakfast, try switching to a protein-packed option like eggs and avocado. This swap can help keep your glucose levels more stable.

But food isn’t the only factor. Staying active is just as important for keeping hormones in check.

Using exercise to support hormonal health

Your CGM can also guide your workout routine. Glucose levels naturally shift throughout the menstrual cycle, with levels often peaking during the luteal phase.

Here’s how to align your workouts with your CGM data:

• Plan high-intensity workouts when your glucose is stable.
• Choose low-intensity activities during times of glucose-related stress.
• Add strength training weekly to improve insulin sensitivity.

By aligning exercise with your glucose patterns, you can maximise its impact on hormonal balance. But don’t stop there—stress and sleep play a big role, too.

Managing stress and sleep for hormonal balance

Stress and poor sleep can cause glucose levels to rise, which disrupts hormonal health. Your CGM data can highlight these issues by showing elevated overnight glucose levels or irregular trends.

As Vively’s leading dietitian, Charlotte Battle, emphasised:

“Stress and poor sleep can have a direct impact on glucose levels, which in turn affects hormonal balance. By tracking your CGM data, you can identify patterns—like elevated overnight glucose or irregular trends—and make adjustments to support better sleep, lower stress, and overall hormonal health.”

To address this:

• Look for patterns in overnight glucose levels to spot stress-related disruptions.
• Use relaxation techniques, such as deep breathing or meditation, to lower stress.
• Stick to a consistent sleep schedule to improve recovery and support hormonal health.

You can also monitor your morning fasting glucose to evaluate your sleep quality and make adjustments to your routine if needed. These small changes can go a long way in maintaining hormonal balance.

Using CGMs for specific hormonal conditions

CGM gives you a clearer picture of how blood sugar affects your hormones, helping you manage conditions like PCOS or menopause with smarter lifestyle choices.

CGMs and PCOS management

Women with PCOS often face challenges like insulin resistance and irregular cycles. CGMs offer real-time insights, helping to pinpoint glucose trends and identify foods or activities that may worsen blood sugar levels and PCOS symptoms.

Beyond PCOS, CGMs are also incredibly useful for understanding blood sugar changes during menopause.

Monitoring menopause with CGMs

The hormonal shifts of menopause can lead to unpredictable blood sugar levels. CGMs make it easier to track and manage these changes by:

• Pinpointing glucose fluctuations that might trigger hot flashes
• Monitoring nighttime glucose levels that could impact sleep quality

These tools are even more effective when paired with other health monitoring devices, offering a clearer picture of hormonal health.

Combining CGMs with other health tools

Using CGMs alongside other health tools can provide deeper insights. For women navigating PCOS or menopause, pairing CGM data with devices like sleep trackers can reveal how lifestyle choices influence hormonal balance.

Helpful tools to pair with CGMs include:

• Activity trackers: Devices like Fitbit or Apple Watch can help you see how exercise impacts glucose levels.
• Sleep monitors: Tools like Oura Ring or Whoop can shed light on how sleep patterns affect blood sugar.
• Stress management apps: Platforms like Calm or Headspace can support mindfulness and reduce stress-related glucose spikes.

‍Research also highlights that glucose levels naturally fluctuate across the menstrual cycle, with peaks often seen during the luteal phase. By combining CGM data with cycle tracking apps like Flo or Clue, women can better understand their unique patterns and make more informed decisions about managing their health.
