What are CGMs?
Continuous Glucose Monitors are small, wearable devices that track blood glucose levels in real time. Typically consisting of a sensor placed under the skin and a transmitter that communicates with a smartphone or receiver, CGMs provide a continuous stream of data on how the body processes glucose throughout the day.
How do CGMs work?
This falls nicely into two parts:
- Sensor Placement: A tiny sensor is inserted under the skin, usually on the abdomen or upper arm. This sensor continuously measures glucose levels in the interstitial fluid, providing a close approximation of blood glucose levels
- Data Transmission: The sensor transmits glucose data to a connected device, such as a smartphone or receiver, in real time. Users can access this information through dedicated apps, allowing for seamless monitoring throughout the day.

Why the sudden rise in CGM use?
In recent years, there has been a remarkable surge in the adoption of CGMs, transforming them from specialised tools primarily used in diabetes management to mainstream devices embraced by a broader audience. There’s a number of factors contributing to their increased use, such as:
- Advancements in Technology - technological advancements have led to CGMs with increased accuracy, providing users with more reliable and precise real-time data on their blood glucose levels. This enhanced accuracy has instilled confidence in the reliability of CGM readings.
- Smaller, User-Friendly Devices - technology evolution has created smaller, more user-friendly devices, making them more comfortable and less obtrusive
- Shift Towards Personalised Healthcare - the ability to receive real-time data on how the body responds to different factors allows individuals to tailor health and fitness strategies based on their unique needs
- Preventive Health Measures - CGMs empower users to take a proactive stance on their health by identifying potential issues before they escalate. This preventive aspect aligns with the growing interest in maintaining overall well-being rather than solely managing existing health conditions.
- Increasing Health Consciousness - as awareness of metabolic health and its impact on overall well-being grows, individuals are seeking tools that provide insights into how lifestyle choices affect their metabolic processes. CGMs, by offering real-time glucose data, fulfill this demand for actionable information
- Fitness Optimisation - beyond health conditions, CGMs have found a place in the fitness community. Athletes and fitness enthusiasts use CGMs to fine-tune their nutrition and exercise routines, aiming for peak performance and recovery.
How you can use a CGM for health and fitness
- Personalised Nutrition: CGMs reveal how different foods impact blood glucose levels individually. Users can tailor their diets based on real-time data, identifying foods that promote stable glucose levels and avoiding those causing spikes.
- Meal Timing: CGMs help users understand the ideal timing for meals and snacks to maintain steady energy levels and prevent fluctuations in blood sugar.
- Enhancing Physical Activity: CGMs provide insights into how the body responds to different types and intensities of exercise. Users can adjust their workout routines to optimize glucose levels during and after physical activity.
- Timing Workouts: Understanding how glucose levels fluctuate throughout the day allows users to time their workouts for maximum efficiency and effectiveness.
- Stress Impact: CGMs can reveal how stress influences blood glucose levels. Managing stress through mindfulness, meditation, or other techniques can positively impact overall health.
- Sleep Patterns: Monitoring glucose levels during sleep provides insights into how sleep quality may affect metabolic health. Users can make adjustments to improve sleep patterns and overall well-being.
Now let's take a look at the advantages and disadvantages of CGMs
Advantages of Continuous Glucose Monitors
- Personalised Insights: CGMs empower individuals with personalised data, allowing them to make informed decisions based on their unique physiological responses.
- Improved Energy Levels: By optimising diet, exercise and lifestyle choices, users can experience more stable energy levels throughout the day.
- Enhanced Accountability: Continuous monitoring fosters a sense of accountability, encouraging individuals to make healthier choices and track their progress over time.
- Real-time Insights: CGMs provide continuous, real-time data on blood glucose levels, offering individuals valuable insights into how their bodies respond to various lifestyle factors, including diet, exercise, stress and sleep.
- Optimised Nutrition: CGMs help users identify foods that have a minimal impact on blood glucose levels, enabling them to make informed dietary choices that contribute to overall health and weight management.
- Enhanced Fitness Optimisation: By understanding how the body responds to different types and intensities of exercise, individuals can optimise their workout routines for improved fitness outcomes and energy management.
- Prevention of Fluctuations: Continuous monitoring allows users to proactively address impending high or low blood sugar levels, helping prevent energy crashes, mood swings, and other symptoms associated with glycemic fluctuations.
- Motivation and Accountability: The data generated by CGMs can serve as a motivator, encouraging individuals to make healthier choices and stay accountable to their health and fitness goals.
- Improved Sleep Management: Monitoring glucose levels during sleep provides insights into how sleep quality may impact metabolic health, allowing users to make adjustments for better sleep hygiene.
Disadvantages of Continuous Glucose Monitors
- Cost: CGMs can be expensive because, not only do you have the cost of the devices, but also some apps charge a subscriptin fee
- Skin Irritation: Continuous wear of CGM sensors may lead to skin irritation or allergic reactions in some users.
- Technical Challenges: Like any technology, CGMs may experience technical issues such as sensor errors or connectivity problems.
- Inconvenient: Some find wearing a CGM continuously inconvenient or uncomfortable.

- Privacy Concerns: The continuous monitoring of health data raises privacy concerns for some users.
- Learning Curve: Understanding and interpreting the data generated by CGMs may require a learning curve. Individuals need to invest time in understanding the device and how to use the information effectively.
- Dependency: There is a risk of becoming overly reliant on CGM data. While it provides valuable insights, individuals should also maintain a holistic approach to health that considers other factors beyond glucose levels.
Advantages and Disadvantages of CGMs - Conclusion
Continuous Glucose Monitors have transcended their initial role in diabetes management and are now valuable tools for the general public seeking to enhance health and fitness.
By providing real-time insights into the impact of diet, exercise, stress, and sleep on blood glucose levels, CGMs empower individuals to make informed decisions that contribute to overall well-being.
As the integration of health technology continues to evolve, CGMs are poised to play a pivotal role in the quest for personalized and optimized health and fitness.
