What Prediabetes Is and Why It Matters

Prediabetes is a condition where blood sugar levels are higher than normal but not yet in the type 2 diabetes range. Most people with prediabetes have no symptoms, which means many don't know they have it until a doctor runs a blood test. Understanding what prediabetes is forms the foundation for exploring how to reverse or manage it.

Blood sugar, also called glucose, comes from the food you eat. Your pancreas produces insulin, a hormone that helps cells absorb this glucose for energy. In prediabetes, your body either doesn't produce enough insulin or doesn't use insulin effectively—a problem called insulin resistance. This causes glucose to build up in your bloodstream instead of entering your cells.

The numbers matter. A normal fasting blood sugar is below 100 mg/dL. Prediabetes is diagnosed when fasting blood sugar is between 100 and 125 mg/dL. Type 2 diabetes begins at 126 mg/dL or higher. Another test, the A1C, measures average blood sugar over three months. Normal A1C is below 5.7%, prediabetes is 5.7% to 6.4%, and diabetes is 6.5% or higher.

According to the Centers for Disease Control and Prevention, more than 96 million American adults have prediabetes—about one in three. Despite these high numbers, only about 11% of people with prediabetes know they have it. This matters because prediabetes significantly increases the risk of developing type 2 diabetes within five to ten years if left unaddressed.

The important thing to know is that prediabetes is not a permanent diagnosis. Research shows that changes in lifestyle and weight can prevent or delay type 2 diabetes. People who lose 5% to 7% of their body weight and increase physical activity can reduce their risk of developing diabetes by about 58%. For adults over 60, the reduction in risk was even greater—71%.

Practical takeaway: Get your blood sugar tested if you haven't recently. A simple fasting blood test or A1C test can tell you where your numbers stand. Knowing your numbers is the first step toward understanding your options.

Lifestyle Changes That Can Reverse Prediabetes

The most well-researched path to reversing prediabetes involves changes to diet, physical activity, and weight. These changes work because they reduce insulin resistance and help your pancreas function more effectively. The good news is that you don't need extreme changes to see results.

Diet modifications focus on the types and amounts of food you eat. People reversing prediabetes benefit from eating more whole grains, vegetables, lean proteins, and healthy fats while reducing refined sugars and processed foods. Specific strategies include choosing brown rice over white rice, eating the skin on apples and potatoes for fiber, and picking grilled chicken instead of fried. Portion control matters too—eating appropriate serving sizes helps manage calorie intake and blood sugar levels.

Research shows that certain dietary patterns work well for blood sugar management. The Mediterranean diet, which emphasizes olive oil, fish, whole grains, and vegetables, has shown benefits in multiple studies. The DASH diet, originally designed to lower blood pressure, also helps improve insulin sensitivity. Neither requires extreme restriction or special foods—both focus on whole foods you can find in any grocery store.

Physical activity reverses prediabetes by making your muscles more sensitive to insulin. When muscles contract during exercise, they pull glucose from your blood without needing as much insulin. The goal is 150 minutes of moderate-intensity activity per week—that's about 30 minutes on five days. Moderate-intensity means you can talk but not sing during the activity. Walking, swimming, cycling, and dancing all count. In addition, muscle-strengthening activities like lifting weights or bodyweight exercises two or more days per week provide additional benefits.

Weight loss amplifies these benefits. Losing just 5% to 7% of your starting weight—roughly 10 to 15 pounds for a 200-pound person—can prevent diabetes from developing. This isn't about reaching an "ideal" weight; it's about reducing the load on your insulin-producing system. Each pound lost improves how your body handles blood sugar.

Sleep and stress management play supporting roles. Poor sleep and chronic stress both raise cortisol, a hormone that increases blood sugar and insulin resistance. Aiming for seven to nine hours of sleep and using stress-reduction techniques like deep breathing, meditation, or time in nature helps your body regulate blood sugar more effectively.

Practical takeaway: Start with one change rather than trying everything at once. Pick either adding a 20-minute walk three days per week or swapping one sugary drink daily for water. Small, sustainable changes compound over time and are far more likely to stick than overhauls.

Medications and Medical Treatments for Prediabetes

While lifestyle changes are the first-line treatment, medications can play a role in managing prediabetes, particularly for people at very high risk of developing diabetes or those unable to make sufficient lifestyle changes. Understanding what medications are available and how they work helps you have informed conversations with your healthcare provider.

Metformin is the primary medication used for prediabetes. It works by reducing the amount of glucose your liver produces and improving how your cells respond to insulin. The medication doesn't cause weight loss, but it doesn't typically cause weight gain either. Metformin is well-tolerated by most people, though some experience digestive side effects like nausea or diarrhea, usually temporary and manageable by taking it with food or adjusting the dose.

Clinical trials, particularly the Diabetes Prevention Program (DPP) study, showed that metformin reduced diabetes risk by 31% in people with prediabetes over three years. However, lifestyle changes—diet and exercise—reduced risk by 58%, making them significantly more effective. The combination of metformin plus lifestyle changes provides even greater benefit than either alone. Cost is also a consideration: metformin is inexpensive, often costing just a few dollars per month with insurance or at discount pharmacies.

GLP-1 receptor agonists are a newer class of medications that increase insulin production and help people feel full longer. Medications in this category include semaglutide (Ozempic, Wegovy) and tirzepatide (Zepbound, Mounjaro). These drugs have shown impressive results for weight loss and blood sugar control. A recent trial showed that tirzepatide reduced the risk of developing diabetes by 94% in people with prediabetes. However, these medications are expensive—often $1,000 or more per month—and insurance coverage for prediabetes specifically is limited, though this is changing.

Other medications sometimes used include acarbose, which slows carbohydrate digestion, and thiazolidinediones, which improve insulin sensitivity. These are less commonly prescribed for prediabetes than metformin but may be options in specific situations.

Important considerations about medication: medications work best combined with lifestyle changes rather than as replacements for them. They also require ongoing use—stopping medication often allows blood sugar to return to prediabetic levels. Your doctor can discuss which medication, if any, might make sense based on your individual risk factors, other health conditions, and preferences.

Practical takeaway: Ask your doctor whether metformin might benefit you. If discussed, questions to ask include: How long would I take it? What side effects are possible? Could it be combined with lifestyle changes? What's the cost with my insurance?

Monitoring Your Progress and Understanding Test Results

Tracking your progress toward reversing prediabetes requires understanding the tests your doctor uses and learning to monitor patterns in your daily blood sugar. Regular testing provides concrete evidence that your efforts are working and helps adjust your approach if needed.

Medical tests measure your blood sugar status at specific points in time and over longer periods. The fasting blood glucose test measures your blood sugar after not eating for eight hours—typically done in the morning. The A1C test reflects your average blood sugar over the previous two to three months by measuring how much glucose has attached to hemoglobin, a protein in red blood cells. The oral glucose tolerance test involves drinking a sugary liquid and measuring blood sugar response over two hours
