Should you monitor your blood sugar if you don't have diabetes? Here's what you should know

Blood sugar monitoring is essential for managing diabetes, but its growing popularity among non-diabetics raises questions. With wearable health technology becoming more accessible, many people without diabetes are tracking their glucose levels to understand how food, exercise, and lifestyle choices affect their bodies. Advocates believe it offers insights into overall health and helps optimise diet and fitness routines. However, experts caution that constant monitoring may not be necessary for healthy individuals and could lead to unnecessary anxiety or misinterpretation of data. Before adopting this trend, it’s important to understand its real benefits, limitations, and whether it’s truly needed for you.


Understanding blood sugar in non-diabetics
In healthy people, the body usually controls blood sugar well with the help of insulin and other hormones. Fasting blood sugar and the rise after meals stay within a normal range. Because of this, most people without diabetes or prediabetes do not need to check their blood sugar often. Occasional checks during regular health check-ups are enough unless there are risk factors like being overweight, having a family history of diabetes, or metabolic syndrome.

According to a study published in PLOS ONE, regular self-monitoring of blood sugar in people with type 2 diabetes who do not use insulin shows little benefit in controlling blood sugar compared to not monitoring at all. The study found that self-monitoring may help in certain cases, such as when starting new medication or checking for low blood sugar, but it is not always necessary for everyone with type 2 diabetes.



Potential benefits of monitoring without diabetes

• Early detection: Monitoring may help identify signs of prediabetes early, especially in people with lifestyle or genetic risks.
• Better lifestyle awareness: Seeing how different foods, workouts, or sleep patterns affect glucose can motivate healthier habits.

However, these benefits often matter more to individuals aiming for optimisation rather than medical necessity.



Risks and downsides of monitoring without need

• Increased anxiety: Constant monitoring can create stress and lead to unnecessary worry over normal fluctuations.
• Expense: Glucose monitoring devices and sensors can be costly and are rarely covered for those without a diagnosis.
• Data misinterpretation: Readings can be misunderstood without proper context, leading to misguided dietary or lifestyle changes.

The rise of Continuous Glucose Monitors (CGMs)
Continuous glucose monitors, originally developed for diabetes management, have become popular among fitness enthusiasts and biohackers. These devices provide real-time insights into how food, exercise, sleep, and stress impact blood sugar. The idea of personalised health tracking appeals to many, but is it medically necessary for someone without blood sugar issues?



Smarter ways to support blood sugar without devices
If you want to maintain healthy blood sugar levels, focus on these practical strategies:

• Eat balanced meals: Include fibre, lean proteins, and healthy fats to prevent sharp spikes.
• Stay physically active: Exercise improves insulin sensitivity and supports overall metabolic health.
• Prioritise sleep and stress management: Poor sleep and high stress can raise cortisol, which influences glucose levels.
• Stay hydrated and limit alcohol: Both dehydration and excess alcohol can disrupt normal blood sugar regulation.

FAQs
1. Do healthy people need to check blood sugar regularly?
No, healthy individuals with no signs of diabetes or prediabetes do not need regular glucose checks.

2. Can monitoring blood sugar prevent diabetes?
Not directly. However, it may help people at risk identify unhealthy patterns and make lifestyle changes early.

3. Are glucose monitors accurate for everyone?
Continuous glucose monitors are generally accurate but should not replace professional medical tests and advice.

4. What is a normal blood sugar level?
For most healthy adults, blood sugar stays within a regulated range through the body’s natural processes.

5. What’s the best way to maintain healthy blood sugar?
A balanced diet, regular exercise, stress management, and routine check-ups are the most effective strategies.
