Imagine receiving a call from your healthcare provider after a routine blood test. The news isn’t catastrophic, but it’s concerning: “Your blood glucose levels are higher than normal, but not high enough to be diagnosed as diabetes. You have prediabetes.” This scenario unfolds for millions of Canadians each year, often catching them completely by surprise.
At Care& Family Health, we regularly see patients who are shocked to learn they have prediabetes despite feeling perfectly healthy. This condition—which affects approximately 6.1 million Canadians—represents a critical crossroads in your health journey, a warning sign your body is giving you before more serious problems develop.
The good news? Prediabetes doesn’t have to lead to type 2 diabetes. With proper understanding and proactive steps, you can potentially reverse this condition and prevent progression to diabetes. This window of opportunity is precisely why recognizing and addressing prediabetes is so important.
In this comprehensive guide, we’ll explore what prediabetes is, how to identify it, and most importantly, the evidence-based strategies that can help you regain control of your health.
What Exactly Is Prediabetes?
Prediabetes is a metabolic condition characterized by blood glucose (sugar) levels that are higher than normal but not yet high enough to be classified as type 2 diabetes. It’s essentially your body signaling that your glucose metabolism is becoming impaired.
The Diagnostic Criteria
In Canada, healthcare providers diagnose prediabetes based on one of these test results:
- Fasting Plasma Glucose (FPG): 6.1 to 6.9 mmol/L (110 to 125 mg/dL)
- Oral Glucose Tolerance Test (OGTT): 7.8 to 11.0 mmol/L (140 to 199 mg/dL) two hours after consuming a 75g glucose drink
- Hemoglobin A1C (HbA1C): 6.0% to 6.4% (42 to 47 mmol/mol)
These numbers represent the threshold between normal glucose metabolism and diabetes. But what’s happening inside your body when these numbers begin to rise?
The Physiological Process
Prediabetes develops when your body starts to struggle with insulin—the hormone responsible for helping cells absorb glucose from your bloodstream. This typically occurs in one of two ways:
- Insulin Resistance: Your cells don’t respond normally to insulin, requiring more insulin to achieve the same glucose-lowering effect.
- Declining Insulin Production: Your pancreas can’t produce enough insulin to overcome even mild resistance.
Over time, these issues can worsen, eventually leading to type 2 diabetes if left unaddressed.

With the Care& app, you can easily track important health metrics like blood glucose readings over time, helping you and your healthcare provider monitor your progress. Set reminders for testing, log your results, and discuss trends during your unlimited Nurse Practitioner appointments.
Why Prediabetes Often Goes Undetected
One of the most challenging aspects of prediabetes is its silent nature. Unlike many health conditions, prediabetes typically presents no obvious symptoms. This explains why approximately 90% of those with prediabetes don’t know they have it.
Some people might experience subtle signs that something is amiss:
- Increased thirst
- Frequent urination
- Unexplained fatigue
- Blurry vision
- Darkened skin areas (acanthosis nigricans), particularly around the neck, armpits, or groin
However, these symptoms are often mild enough to be attributed to stress, aging, or other factors—making regular screening the most reliable detection method.
Who Should Be Screened for Prediabetes?
Given the often symptomless nature of prediabetes, proactive screening becomes essential for early detection. Diabetes Canada recommends screening for adults who have one or more risk factors:
Risk Factors for Prediabetes
Age & Family History
- Age: 40 years or older
- Family history: Having a first-degree relative with type 2 diabetes
Ethnicity & Personal History
- Higher risk among: Indigenous, African, Arab, East Asian, Hispanic, South Asian, or Pacific Island populations
- History: Of gestational diabetes or giving birth to a baby weighing over 4kg (9lbs)
Cardiovascular & Associated Factors
- Cardiovascular risk factors: High blood pressure, elevated cholesterol, or obesity (especially abdominal obesity)
- Associated conditions: Polycystic ovary syndrome, psychiatric disorders, HIV, obstructive sleep apnea
Medical History
- Previous history: Of impaired glucose tolerance or impaired fasting glucose
- Medication use: Long-term or high-dose corticosteroid treatment
If you have multiple risk factors, discussing appropriate screening with your healthcare provider is particularly important. At our medical clinic, we help patients understand their individual risk profile and determine the right screening approach.

The Significance of Early Intervention
Learning you have prediabetes might feel discouraging, but healthcare providers often describe it as an opportunity—a chance to make changes before diabetes develops. Research confirms the power of this opportunity:
- The landmark Diabetes Prevention Program (DPP) study found that lifestyle changes reduced the risk of developing type 2 diabetes by 58% over three years.
- Even more impressive, these interventions worked better than medication (metformin), which reduced risk by 31%.
- Follow-up studies show the benefits persist long-term, with risk reduction of 34% even after 10 years.
Early intervention not only helps prevent diabetes but also reduces your risk of developing complications that can begin during the prediabetes stage, including heart disease and stroke.
Evidence-Based Strategies for Reversing Prediabetes
The cornerstone of prediabetes management involves lifestyle modifications that improve your body’s ability to use insulin and maintain healthy blood glucose levels. Here’s what the research shows works best:
1. Gradual, Sustainable Weight Loss
If you’re carrying excess weight, losing even a modest amount can significantly impact your blood sugar levels. The DPP study found that losing just 5-7% of body weight (10-14 pounds for a 200-pound person) reduced diabetes risk dramatically.
Practical approach: Rather than drastic dieting, focus on creating a small calorie deficit through a combination of dietary changes and increased physical activity. A sustainable goal might be 0.5-1 kg (1-2 pounds) per week.
2. Regular Physical Activity
Exercise improves insulin sensitivity—sometimes immediately, with benefits lasting 24-48 hours after activity. This is why consistent activity is more important than occasional intense workouts.
Recommended targets:
- Aim for 150 minutes of moderate-intensity activity weekly (30 minutes, 5 days per week)
- Include both aerobic exercise and resistance training
- Break up periods of sitting with short activity breaks
Getting started: If you’re currently inactive, begin with just 5-10 minutes daily and gradually increase. Activities like brisk walking require no special equipment and can be integrated into your daily routine.
3. Dietary Modifications
No single “perfect” diet exists for prediabetes, but certain principles consistently show benefits:
Focus on:
- Fiber-rich foods: Vegetables, fruits, legumes, and whole grains help improve blood sugar control and promote satiety.
- Quality protein sources: Fish, poultry, plant proteins, and moderate amounts of unprocessed red meat.
- Healthy fats: Olive oil, avocados, nuts, and fatty fish contain beneficial fats that can improve insulin sensitivity.
Limit:
- Refined carbohydrates: White bread, white rice, and processed cereals can cause blood sugar spikes.
- Added sugars: Especially in beverages, which provide calories without satiety.
- Highly processed foods: These often combine refined carbs, unhealthy fats, and high sodium.
The Mediterranean, DASH, and plant-focused diets all align with these principles and have shown benefits for metabolic health.
4. Adequate Sleep and Stress Management
Often overlooked factors that significantly impact blood glucose levels include:
Sleep quality and quantity: Poor sleep affects hunger hormones and insulin sensitivity. Aim for 7-9 hours of quality sleep.
Chronic stress: Stress hormones like cortisol can raise blood glucose. Incorporating stress-reduction techniques such as mindfulness, deep breathing, or gentle movement practices can help manage these effects.
5. Medication (When Appropriate)
While lifestyle changes remain the foundation of prediabetes management, some patients may benefit from medication:
Metformin: Sometimes prescribed for those with multiple risk factors or those who have not responded adequately to lifestyle interventions.
Other medications: May be considered in specific circumstances under guidance from a healthcare provider.

If someone you care about has prediabetes, your support can make a significant difference in their journey:
Participate in healthy changes
Adopt similar dietary patterns or exercise together to make changes feel more like a shared lifestyle than a restriction.
Focus on positive additions
Emphasize what can be added (vegetables, activity, relaxation) rather than what should be restricted.
Avoid judgment
Offer encouragement without criticism, recognizing that change is challenging and setbacks are normal.
Recognize effort
Acknowledge progress regardless of immediate results, understanding that health improvements aren’t always visible.
Learn together
Understand prediabetes management so you can provide informed support and engage in productive conversations about health.
Family support creates an environment where healthy choices become easier and more sustainable.
Moving Forward: Turning Diagnosis into Empowerment
A prediabetes diagnosis represents a crossroads—a moment when informed choices can significantly alter your health trajectory. By understanding this condition and implementing evidence-based strategies, many people successfully prevent progression to type 2 diabetes.
Remember that small, consistent changes often produce the most sustainable results. Whether you’re making dietary adjustments, increasing physical activity, improving sleep habits, or managing stress more effectively, each positive step contributes to better metabolic health.

Frequently Asked Questions About Prediabetes
Can prediabetes be completely reversed?
Yes, prediabetes can often be reversed, particularly when caught early. Research shows that approximately 25-30% of people with prediabetes return to normal glucose levels through sustained lifestyle changes. Even those who don’t achieve complete reversal can significantly delay or prevent progression to type 2 diabetes through proper management strategies.
How quickly can lifestyle changes impact blood glucose levels?
Many patients see improvements in blood glucose measurements within weeks of implementing lifestyle changes, although the timeline varies by individual. Some studies show measurable improvements in insulin sensitivity after just one week of increased physical activity. However, sustainable improvements typically require consistent effort over months, with continued monitoring and adjustments to your approach as needed.
Should I avoid carbohydrates completely if I have prediabetes?
No, eliminating carbohydrates completely isn’t necessary or recommended. The quality, quantity, and combination of carbohydrates matter more than complete avoidance. Focus on complex carbohydrates with high fiber content (vegetables, whole grains, legumes), consume them in appropriate portions, and pair them with proteins and healthy fats to minimize blood sugar spikes. A Nurse Practitioner can help develop an eating plan that works for your specific metabolism and preferences.
How often should someone with prediabetes be tested to monitor progression?
Diabetes Canada recommends that individuals with prediabetes have their blood glucose levels checked annually, though your healthcare provider may suggest more frequent monitoring depending on your risk factors and initial test results. At Care&, we work with patients to establish personalized monitoring schedules, with the benefit of unlimited appointments allowing for appropriate follow-up without access barriers.
