Diabetes and Prediabetes: What’s the Difference?
Causes and Risk Factors
Risk factors for insulin resistance and diabetes are influenced by both lifestyle choices and genetics. Recognizing these factors can help you take proactive steps to manage your health before blood sugar levels reach unsafe levels.
How Insulin Resistance Works
Insulin acts like a key, allowing cells to absorb glucose. With insulin resistance, cells in your muscles, fat, and liver stop responding effectively to insulin's signal, making it harder for glucose to enter. This happens because cell receptors change, reducing insulin's effectiveness.
"The two are very closely related. Insulin resistance can lead to prediabetes and most people with prediabetes have insulin resistance." - Sydney Blount, MD, Nebraska Medicine endocrinologist
Here’s how the process unfolds:
At first, your pancreas compensates by producing more insulin. But over time, it can’t keep up, leading to rising blood sugar levels. When sugar levels stay high, your body stores the excess. It starts with the liver and muscles, but once those are full, the liver converts the extra sugar into fat. This explains why weight gain is often linked to insulin resistance.
This cycle creates additional health risks. Dr. Anika Anam from Yale Medicine notes, "Prediabetes goes hand in hand with metabolic syndrome, the term for a condition that includes hypertension, obesity, and high cholesterol". These factors combine over time, increasing the risk of serious complications.
One of the most critical changes involves the pancreas's beta cells, which produce insulin. Over time, these cells lose the ability to release insulin quickly after meals. This decline in first-phase insulin secretion is a key driver in the development of Type 2 diabetes.
This sets the stage for how lifestyle choices and genetic predispositions interact to affect diabetes risk.
Lifestyle and Genetic Factors
Controllable Risk Factors:
- Weight and body composition: Obesity significantly raises the risk of Type 2 diabetes. A 2020 study found that individuals with obesity were about six times more likely to develop the condition compared to those at a healthy weight. Even small weight losses can make a big difference. For example, losing just 11 pounds (5 kg) has been linked to a 58% reduction in diabetes risk.
- Physical activity: Regular exercise improves insulin sensitivity. Studies show that high energy intake can increase diabetes risk by 11% to 26%, while staying active reduces it by 8% to 30%. Activities like brisk walking for 2.5 hours a week are associated with a 27% lower risk, regardless of body weight.
- Diet: What you eat plays a major role. Consuming more than one sugar-sweetened drink a day raises diabetes risk by 26%, while a diet rich in fiber, whole grains, and low in saturated fat can lower the risk of both obesity and diabetes.
Uncontrollable Risk Factors:
Genetics also play a role, but they don’t act alone. Research indicates that both Type 1 and Type 2 diabetes require a genetic predisposition and an environmental trigger to develop. Type 2 diabetes is more strongly linked to family history than Type 1, but lifestyle choices can still influence outcomes.
Other contributors to insulin resistance include certain medications, hormonal imbalances, chronic stress, and aging. For instance, as of 2012, 37% of adults over 20 had prediabetes.
The good news is that early intervention can make a big difference. By adopting healthier habits, you can prevent or even reverse insulin resistance and prediabetes. Regular physical activity improves insulin sensitivity, while weight loss reduces strain on your body. A balanced diet featuring non-starchy vegetables, fruits, whole grains, and lean proteins can help manage blood sugar levels.
Understanding these risk factors gives you the tools to make informed choices. Without intervention, people with prediabetes are at a high risk of progressing to Type 2 diabetes within 5 to 10 years.
Blood Sugar Tests and Diagnosis
Knowing the thresholds for normal blood sugar, prediabetes, and Type 2 diabetes is key to understanding your health. These tests provide measurable benchmarks that help healthcare providers assess your current condition and risk factors.
A diagnosis typically requires two separate tests on different days, unless your blood sugar levels are extremely high or you show classic symptoms of diabetes. This method ensures accuracy and reduces the chance of misdiagnosing temporary blood sugar spikes.
Blood Sugar Level Ranges
Familiarizing yourself with the specific numbers that define each condition can help you better understand your test results and keep track of your progress. Here's a quick look at the thresholds:
Test | Normal | Prediabetes | Type 2 Diabetes |
---|---|---|---|
A1C | Less than 5.7% | 5.7% to 6.4% | 6.5% or higher |
Fasting Plasma Glucose (FPG) | Less than 100 mg/dL | 100 to 125 mg/dL | 126 mg/dL or higher |
Oral Glucose Tolerance Test (OGTT) | Less than 140 mg/dL | 140 to 199 mg/dL | 200 mg/dL or higher |
Prediabetes acts as a warning sign - your blood sugar levels are higher than normal but not yet in the diabetes range. This stage provides a critical window to make changes that could prevent progression to Type 2 diabetes.
Next, let’s explore the tests used to determine these levels and evaluate how your body handles glucose.
Common Diagnostic Tests
Three main tests are used to diagnose prediabetes and Type 2 diabetes. Each one offers unique insights into your blood sugar trends and metabolic function.
A1C Test (Hemoglobin A1C)
The A1C test provides a snapshot of your average blood sugar levels over the past 2–3 months. It doesn’t require fasting, making it convenient and reducing the need for multiple lab visits. By measuring how much glucose has attached to your red blood cells, it gives a stable view of your long-term blood sugar control. However, it’s worth noting that some people may have a normal fasting glucose level while their A1C falls into the prediabetes range.
Fasting Plasma Glucose Test (FPG)
The FPG test measures your blood sugar after you’ve fasted for at least 8 hours. Often done in the morning, this test is a reliable and cost-effective way to check how well your body regulates blood sugar when you’re not eating. It’s particularly useful for identifying early signs of glucose metabolism issues.
Oral Glucose Tolerance Test (OGTT)
The OGTT involves checking your blood sugar before and two hours after drinking a glucose solution containing 75 grams of sugar. Though it’s more expensive, this test provides valuable information about how your body responds to a sugar load, making it especially useful for diagnosing conditions like gestational diabetes or early Type 2 diabetes.
Testing Frequency and Follow-up
For those with prediabetes, doctors recommend screening for Type 2 diabetes every 1–2 years. Adults with normal blood sugar levels should get tested every 3 years, according to the United States Preventive Services Task Force (USPSTF). Your healthcare provider will tailor your testing schedule based on your age and personal risk factors.
Regular testing is critical. Around 13% of U.S. adults have diabetes, and 34.5% fall into the prediabetes category. Shockingly, 21.4% of people with diabetes don’t know they have it, and only 15.3% of those with prediabetes have been informed by a healthcare provider.
If your doctor strongly suspects prediabetes but your initial test comes back normal, they may suggest repeating the test or using another type of screening. This ensures that subtle changes in your metabolism aren’t overlooked, giving you the chance to take action early.
These guidelines are the foundation for effectively managing your metabolic health and staying ahead of potential complications.
Symptoms and Health Risks
Recognizing the signs of prediabetes and Type 2 diabetes can mean the difference between catching the condition early or facing serious complications. The tricky part? Prediabetes often flies under the radar, while Type 2 diabetes tends to come with more noticeable symptoms.
How Symptoms Differ
The key difference between prediabetes and Type 2 diabetes lies in how symptoms show up - or don’t. Prediabetes is often silent at first, with over 80% of Americans who have it completely unaware of their condition.
When prediabetes does cause symptoms, they’re usually mild. You might experience things like increased thirst, occasional blurry vision, or more frequent urination. Type 2 diabetes, on the other hand, tends to bring on more obvious and persistent symptoms as it develops. These include:
- Constant thirst and frequent trips to the bathroom, as your body works to flush out excess sugar
- Feeling tired all the time, no matter how much rest you get
- Being hungry even after eating
- Blurred vision that doesn’t seem to go away
- Losing weight unexpectedly, even if you’re eating normally
- Cuts or sores that heal slower than usual
- Frequent infections, especially skin or urinary tract infections
Here’s a side-by-side look at how symptoms compare:
Symptom | Prediabetes | Type 2 Diabetes |
---|---|---|
Excessive Thirst | Occasionally, due to higher blood sugar | Very common, as the body loses fluids |
Frequent Urination | May happen now and then | Frequent, often at night |
Fatigue | Mild and easy to dismiss | Persistent and hard to ignore |
Blurred Vision | Sporadic episodes | More frequent and concerning |
Weight Changes | Rare | Common, with unexplained weight loss |
This silent nature of prediabetes is why nearly 38% of U.S. adults have it, yet most remain undiagnosed. The Centers for Disease Control and Prevention (CDC) highlights that a prediabetes diagnosis is a critical opportunity to prevent Type 2 diabetes.
Health Problems from Untreated Type 2 Diabetes
While prediabetes might seem harmless at first, ignoring it can lead to serious health risks. And if Type 2 diabetes goes untreated, the complications can be life-altering.
Prediabetes Health Risks
Even without noticeable symptoms, prediabetes can quietly impact your health. It significantly raises the risk of heart disease and stroke. Without intervention, many people progress to Type 2 diabetes within five years. Alarmingly, about one-third of individuals with undiagnosed prediabetes already show signs of cardiovascular issues. For those around age 45 with prediabetes, the chance of developing Type 2 diabetes within a decade ranges from 9% to 14%.
Type 2 Diabetes Complications
When Type 2 diabetes is left untreated, it can wreak havoc on multiple organs. Dr. Vidya Aluri from UnityPoint Health explains:
"Diabetes is a condition expected to gradually progress over time. If type 2 diabetes goes untreated, the high blood sugar can affect various cells and organs in the body. Complications include kidney damage, often leading to dialysis, eye damage, which could result in blindness, or an increased risk for heart disease or stroke. Unfortunately, the effects of high blood sugars are not limited to this".
Some of the most severe complications include:
- Kidney Damage (Diabetic Nephropathy): High blood sugar harms the delicate blood vessels in your kidneys, potentially leading to kidney failure and dialysis.
- Eye Issues (Diabetic Retinopathy): Damage to the retina’s blood vessels can lead to blindness. Regular eye exams are a must for anyone with diabetes.
- Nerve Damage (Diabetic Neuropathy): High glucose levels can harm nerves, often starting in the feet and legs, causing pain, tingling, or numbness.
- Heart and Stroke Risks: People with diabetes face a much higher likelihood of heart attacks and strokes compared to those without the condition.
- Mental Health Challenges: Diabetes doubles the risk of depression, creating additional hurdles for those managing the condition.
- Acute Emergencies: In severe cases, untreated diabetes can lead to life-threatening conditions like diabetic coma.
The transition from prediabetes to Type 2 diabetes is a crucial period for intervention. With over one-third of U.S. adults affected by prediabetes, early detection and lifestyle changes can delay or even prevent diabetes, improving long-term health. Dr. Frederick Lim, an endocrinologist at AdventHealth Dade City, stresses:
"Diagnosing diabetes early is vital to lowering your risk of developing complications related to the disease".
Diabetes doesn’t just affect blood sugar - it impacts nearly every organ. Spotting it early and taking action can make all the difference in preventing these serious complications.

Treatment and Management Options
When it comes to managing prediabetes and Type 2 diabetes, early action is a game-changer. While prediabetes often improves with lifestyle adjustments alone, managing Type 2 diabetes usually requires a combination of lifestyle changes and medical treatments. Let’s break it down.
Treating Prediabetes
Lifestyle changes are the cornerstone of prediabetes treatment. As the Centers for Disease Control and Prevention wisely put it:
"Life doesn't always give you the time to change the outcome. Prediabetes does".
This is a critical opportunity to prevent diabetes from progressing further, and studies show that timely intervention can make a huge difference.
Weight Loss: Small Changes, Big Impact
Even modest weight loss can significantly lower the risk of developing diabetes. Dropping just 5% to 10% of your body weight can cut the risk of diabetes by more than half. For someone weighing 200 pounds, losing just 10-20 pounds could be enough to make a meaningful difference.
The Power of Exercise
Exercise is another powerful tool for controlling blood sugar. Just one session of moderate-intensity exercise can improve glucose uptake into muscles by at least 40%. Aiming for 150 minutes of moderate to vigorous activity per week - or roughly 10,000 steps a day - can work wonders.
Interestingly, research shows that even without weight loss, exercise alone can reduce the risk of diabetes. In the Diabetes Prevention Program (DPP), participants who exercised 150 minutes a week reduced their diabetes risk by 46%, even if they didn’t hit their weight loss goals.
Eating Smarter, Not Harder
Tara Seymour, M.S., R.D., L.D.N., C.D.C.E.S., offers this practical advice:
"People with prediabetes do not have to eliminate entire food groups. All foods can fit in the meal plan, and patients should steer clear of fad diets and other strategies that promise quick fixes, since their claims are not supported. We encourage making gradual behavior changes. Small changes can lead to big results".
The Mediterranean diet is often recommended for prediabetes. It emphasizes fiber-rich foods - like fruits, vegetables, and whole grains - with a goal of 25 to 30 grams of fiber per day. Maintaining a healthy body weight is also key: a body mass index (BMI) of 25 or lower is ideal, and waist circumference should stay under 35 inches for women and 40 inches for men.
When Medication Becomes Necessary
If lifestyle changes alone don’t yield results, medication may be prescribed. However, the focus remains on diet and exercise as the foundation of treatment.
Managing Type 2 Diabetes
Managing Type 2 diabetes requires a more involved approach, combining lifestyle changes, medications, and regular monitoring.
Monitoring Blood Sugar Levels
Blood glucose monitoring (BGM) is an essential part of diabetes management. It’s particularly important for individuals using insulin, as it helps guide dosage and prevents hypoglycemia. Monitoring also helps assess how noninsulin medications and lifestyle changes are affecting blood sugar levels.
A certified diabetes care and education specialist can teach you how to interpret your blood sugar numbers and adjust your treatment plan accordingly.
Medications: Starting with Metformin
Metformin is often the first medication prescribed for Type 2 diabetes. It’s affordable, well-researched, and works by improving how your body responds to insulin while reducing the amount of glucose produced by your liver.
For more severe cases, basal insulin might be introduced initially, alongside metformin, to quickly bring blood sugar levels under control. Over time, as β-cell function deteriorates, treatment plans may need to evolve to address these changes.
Lifestyle Adjustments Still Matter
Even with medication, lifestyle changes remain vital. Adults with diabetes are encouraged to get at least 150 minutes of moderate-to-vigorous aerobic exercise each week, spread over at least three days, along with two to three sessions of resistance training on nonconsecutive days.
Studies show that exercise can lower HbA1c levels by 0.67%, whether it’s aerobic, resistance, or a combination of both. All forms of exercise are effective at improving blood sugar control.
Nutrition: A Balanced Plate
Nutrition plays a critical role in managing Type 2 diabetes. Focus on:
- Whole-grain, high-fiber starches
- Non-starchy vegetables
- Proper portion sizes for fruits
- Lean meats and low-fat dairy
- Healthy fats like those found in nuts and olive oil
- Heart-healthy fish
At the same time, limit saturated fats, trans fats, sodium, and added sugars. Eating regular, balanced meals is key to keeping blood sugar levels stable. Consistency in carbohydrate intake across meals also helps maintain target sugar levels.
Medical nutrition therapy has been shown to lower HbA1c levels by 0.3–2.0%, proving how impactful dietary changes can be when combined with medication.
While prediabetes can often be managed with lifestyle changes alone, treating Type 2 diabetes usually requires a combination of medication, lifestyle adjustments, and consistent monitoring. Early action and a steady commitment to your plan are essential for managing both conditions effectively.
Disease Progression and Outlook
Understanding the progression of prediabetes and Type 2 diabetes can help you make informed health decisions. While prediabetes doesn’t have to lead to diabetes, Type 2 diabetes, though a lifelong condition, can be effectively managed with the right strategies.
Can Prediabetes Be Reversed?
Yes, prediabetes can be reversed through lifestyle changes, giving you the chance to alter its course. Currently, 98 million adults in the U.S. - about one in three - are living with prediabetes.
The Role of Modest Weight Loss
The CDC’s Diabetes Prevention Program (DPP) highlights how impactful structured lifestyle changes can be. People with prediabetes who lost just 5% to 7% of their body weight reduced their risk of developing Type 2 diabetes by 58%. That means if you weigh 180 pounds, shedding as little as 9 to 13 pounds could cut your risk by more than half.
Dr. Sonia Caprio, a pediatric endocrinologist at Yale Medicine, explains:
"Often only minor changes in dietary intake and minimal weight loss, together with more physical activity, will help chase diabetes away".
Act Quickly - Time Matters
Without intervention, 37% of people with prediabetes will develop diabetes within four years. However, lifestyle changes can lower that number to around 20%. For a 45-year-old with prediabetes, the 10-year risk of developing Type 2 diabetes is estimated to be between 9% and 14%.
Your HbA1c levels also play a critical role. Individuals with an HbA1c of 6.0% or higher face a 25% to 50% chance of progressing to diabetes within five years.
Why Early Action Is Key
Taking action early, especially for younger individuals, is essential. The CDC reports that 18% of adolescents have prediabetes, and this number is growing. Dr. Anam emphasizes the benefits of starting early:
"I've had patients achieve tremendous things", she says, noting that early intervention makes a big difference.
Key steps to reversing prediabetes include regular physical activity (aiming for at least 150 minutes per week), following a balanced diet similar to the Mediterranean diet while cutting back on added sugars and refined carbs, and keeping a close eye on your blood glucose levels.
These measures also set the stage for long-term management of Type 2 diabetes.
Living with Type 2 Diabetes Long-Term
While prediabetes can often be reversed, managing Type 2 diabetes requires ongoing care and dedication. With the right approach, people with diabetes can lead full, healthy lives and reduce their risk of complications.
The Long-Term Impact on Health
The risk of all-cause death is 60% to 100% higher for people with diabetes compared to those without it. However, this statistic largely reflects cases of poorly managed diabetes. With effective treatment and lifestyle adjustments, outcomes can improve significantly.
Type 2 diabetes can affect almost every major organ, leading to complications such as kidney failure, blindness, and nerve damage. Additionally, individuals with diabetes are two to three times more likely to experience depression and are 20% more likely to develop anxiety than those without the condition.
The Need for Consistent Management
Managing Type 2 diabetes effectively means staying consistent. This includes monitoring blood glucose levels regularly, taking prescribed medications, eating a balanced diet, staying active, and attending routine medical checkups. Early detection and treatment are crucial, as many complications develop over years or even decades.
Weighing the Risks
The risks associated with prediabetes are notably lower than those of full-blown diabetes. For example, while people with prediabetes face an 18% to 47% higher risk of dementia compared to those without the condition, individuals with diabetes face a much higher risk - between 60% and 130%. This comparison highlights the importance of preventing the progression to diabetes.
Both conditions offer a chance to take control. Prediabetes provides a critical window to prevent diabetes entirely, while Type 2 diabetes, when managed well, allows you to maintain an active and fulfilling life. By understanding these conditions, you can make informed choices about your health and adopt the strategies outlined in this guide.
Side-by-Side Comparison: Pre-Diabetes vs Type 2 Diabetes
Understanding the differences between prediabetes and Type 2 diabetes can help you see where you stand and decide on the next steps. Both conditions involve elevated blood sugar levels, but they vary greatly in severity, symptoms, and long-term health risks.
Here’s a breakdown of the key differences:
Aspect | Prediabetes | Type 2 Diabetes |
---|---|---|
A1C Test | 5.7% to 6.4% | 6.5% or higher |
Fasting Plasma Glucose | 100 to 125 mg/dL | 126 mg/dL or higher |
Oral Glucose Tolerance Test | 140 to 199 mg/dL | 200 mg/dL or higher |
Random Plasma Glucose | Not applicable for diagnosis | 200 mg/dL or higher (with symptoms) |
Symptoms | Typically no symptoms | Frequent urination, excessive thirst, extreme hunger, fatigue, blurry vision |
Awareness | Over 80% are unaware they have it | Symptoms may be mild or unnoticed |
Reversibility | Often reversible with lifestyle changes | Requires lifelong management |
Health Risks | Higher risk of heart disease, stroke, and diabetes | Impacts major organs; risks include kidney failure, blindness, nerve damage |
Mortality Risk | 18% to 47% higher risk for dementia | 60% to 130% higher risk for dementia |
Cardiovascular Risk | Moderate increase in heart disease risk | Much higher risk of heart complications |
Cancer Risk | Slightly increased cancer risk | 1.1 to 1.4 times higher cancer incidence |
The Numbers Speak Volumes
Diagnostic thresholds make the distinction clear. For instance, an A1C of 6.3% falls within the prediabetes range, but at 6.5%, you’re officially in the diabetes category. That small 0.2% difference signals a major shift in health risks and treatment strategies.
Health Risks Amplify with Diabetes
The jump in risks from prediabetes to diabetes is dramatic. Prediabetes increases health risks, but diabetes compounds them significantly. For example, while prediabetes raises dementia risk by up to 47%, diabetes can more than double it.
Different Approaches to Treatment
The treatment goals for these conditions also vary. Prediabetes management is centered around lifestyle changes - adjusting your diet, increasing physical activity, and managing weight. The aim is to reverse it and prevent progression to diabetes. On the other hand, managing Type 2 diabetes often involves a combination of lifestyle changes, regular blood sugar monitoring, and medications like metformin to keep the condition under control.
Acting During the Prediabetes Stage
The prediabetes stage offers a critical opportunity for intervention. Without changes, many individuals with prediabetes may develop Type 2 diabetes within five years. The good news? Taking action now - through diet, exercise, and other lifestyle adjustments - can often reverse prediabetes and help you avoid the more severe consequences of diabetes.
Next Steps for Better Health
Understanding how diseases progress is just the beginning. The next step is taking action to protect your health moving forward. If you've been diagnosed with prediabetes or Type 2 diabetes, making immediate lifestyle changes is crucial to avoid complications.
Even small changes can make a big difference. For example, losing a modest amount of weight can significantly reduce your risk of diabetes. Plus, just one session of moderate exercise can boost glucose uptake in your muscles by at least 40%.
To get started, focus on three key areas: diet, exercise, and weight management. Here’s a solid foundation to build on:
- Fiber intake: Aim for 25–30 grams of fiber daily.
- Exercise: Commit to at least 150 minutes of moderate activity each week.
- Weight management: Work toward maintaining a BMI of 25 or lower.
For a more personalized plan, seek advice from healthcare professionals. Joining a CDC-recognized National Diabetes Prevention Program can provide structured support for making lifestyle changes [52, 53]. A registered dietitian nutritionist can also help you design a meal plan tailored to your tastes and schedule.
Monitoring your progress is just as important as making changes. Keeping track of how your food choices, physical activity, and any medications affect your glucose levels can offer valuable insights. If you have prediabetes, annual check-ups are essential to catch any changes early. These regular screenings complement your daily efforts and help you stay ahead of potential complications.
Here’s an eye-opening statistic: 81% of people with prediabetes don’t know they have it. If you’re over 35 and have risk factors like being overweight, it’s time to schedule a screening. Early detection empowers you to take control before more serious issues arise.
"Life doesn't always give you the time to change the outcome. Prediabetes does."
– CDC
The path to better health is built on small, consistent steps. Whether you’re aiming to reverse prediabetes or manage Type 2 diabetes, the choices you make today can shape your future. By focusing on diet, staying active, and monitoring your progress, you can take control and set yourself up for long-term success.
FAQs
How can I find out if I have prediabetes, especially if there are no clear symptoms?
Prediabetes often sneaks in without any obvious symptoms, making it tricky to spot without a blood test. If you're carrying extra weight, have a family history of diabetes, or lead a mostly inactive lifestyle, it's wise to consider getting tested. Here are the most common tests used to diagnose prediabetes:
- A1C test: Results in the range of 5.7% to 6.4% indicate prediabetes.
- Fasting blood glucose: Levels between 100 and 125 mg/dL suggest prediabetes.
- Oral glucose tolerance test: A reading of 140 to 199 mg/dL two hours after drinking a glucose solution signals prediabetes.
Catching prediabetes early is key. Small changes - like eating better, moving more, and keeping your weight in check - can make a big difference in reversing it and lowering your risk of developing Type 2 diabetes.
What are the most effective lifestyle changes to reverse prediabetes?
Reversing prediabetes is achievable with a few focused lifestyle adjustments:
- Lose extra weight: Dropping just 5–10% of your body weight can significantly enhance insulin sensitivity and help stabilize blood sugar levels.
- Get moving: Aim for at least 150 minutes of moderate physical activity each week - think brisk walking, swimming, or cycling - to support better blood sugar management.
- Choose better foods: Center your meals around whole, nutrient-packed options like vegetables, lean proteins, whole grains, and healthy fats. Cut back on processed foods and added sugars.
- Prioritize sleep: Aim for 7–9 hours of quality sleep every night. Restful sleep plays a key role in maintaining healthy blood sugar and overall metabolic function.
- Tackle stress: Chronic stress can interfere with blood sugar control, so try incorporating relaxation techniques like meditation, yoga, or breathing exercises into your routine.
Making steady, intentional changes in these areas can play a crucial role in reversing prediabetes and reducing the risk of Type 2 Diabetes over time.
What role does insulin resistance play in the progression from prediabetes to Type 2 diabetes?
Insulin resistance plays a major role in the shift from prediabetes to Type 2 diabetes. Essentially, when insulin resistance occurs, the body’s cells stop responding properly to insulin - the hormone that helps manage blood sugar levels. In response, the pancreas steps up, producing extra insulin to temporarily keep blood sugar under control.
But this increased workload isn't sustainable. Over time, the pancreas can become overburdened, struggling to produce enough insulin. When that happens, blood sugar levels begin to rise, paving the way for Type 2 diabetes. The good news? Early action can make a big difference. Eating a balanced diet, staying active, and managing weight are all powerful tools to slow - or even stop - this progression.
