Your Questions, Answered
Getting a prediabetes diagnosis often raises more questions than it answers. What does it really mean? Will it turn into diabetes? Do you need medication? This FAQ covers the questions that come up most often, with clear, straightforward answers you can use to make informed decisions about your health.
What exactly is prediabetes?
Prediabetes means your blood sugar levels are higher than normal but not high enough to be classified as type 2 diabetes. It is a warning stage that indicates your body is becoming less efficient at processing glucose. The good news is that prediabetes is reversible with the right lifestyle changes.
How do I know if I have prediabetes?
Prediabetes is diagnosed through blood tests. The most common ones are the hemoglobin A1C test (5.7 to 6.4 percent indicates prediabetes), the fasting blood glucose test (100 to 125 mg/dL), and the oral glucose tolerance test (140 to 199 mg/dL two hours after drinking a glucose solution). Many people have prediabetes without any noticeable symptoms, which is why regular screening is so important.
Will prediabetes always turn into type 2 diabetes?
No. Prediabetes does not automatically progress to type 2 diabetes. With lifestyle changes such as improved diet, regular exercise, and modest weight loss, many people are able to bring their blood sugar levels back to normal. Without intervention, however, studies suggest that a significant number of people with prediabetes will develop type 2 diabetes within five to ten years.
Do I need to take medication for prediabetes?
In most cases, lifestyle changes are the first line of treatment for prediabetes. However, some doctors may prescribe metformin, particularly for people who are at higher risk due to factors like obesity, a strong family history of diabetes, or very high fasting glucose levels. Talk to your healthcare provider about whether medication is appropriate for your situation.
What foods should I avoid?
There are no foods you must completely eliminate, but limiting certain types can help keep blood sugar under control. Sugary drinks, white bread, pastries, candy, and heavily processed snacks cause rapid blood sugar spikes and should be reduced. Instead, focus on whole grains, lean proteins, vegetables, and healthy fats. Our Diet and Nutrition section has detailed guidance on building a prediabetes-friendly eating plan.
How much exercise do I need?
Health guidelines recommend at least 150 minutes of moderate-intensity exercise per week. That translates to about 30 minutes a day, five days a week. Brisk walking, cycling, swimming, and dancing all count. Adding two to three sessions of resistance training (like light weights or bodyweight exercises) per week provides additional benefits for blood sugar management.
How much weight do I need to lose?
Even modest weight loss makes a real difference. Losing 5 to 7 percent of your body weight has been shown to significantly reduce the risk of developing type 2 diabetes. For a person weighing 200 pounds, that is only 10 to 14 pounds. The goal is gradual, sustainable weight loss rather than rapid results from extreme diets.
Can children get prediabetes?
Yes. Prediabetes is becoming more common in children and teenagers, often related to excess weight, sedentary lifestyles, and family history. If your child has risk factors for prediabetes, talk to their pediatrician about screening and healthy lifestyle strategies.
How often should I get tested?
If you have been diagnosed with prediabetes, your doctor will likely recommend retesting your A1C every three to six months to monitor your progress. If you have risk factors but have not been diagnosed, the American Diabetes Association recommends screening starting at age 35, or earlier if you are overweight and have additional risk factors.
Is prediabetes the same as insulin resistance?
They are closely related but not identical. Insulin resistance means your cells do not respond well to insulin, which is the underlying mechanism behind prediabetes. However, you can have some degree of insulin resistance without meeting the blood sugar thresholds for a prediabetes diagnosis. Prediabetes is essentially the point where insulin resistance has progressed enough to show up in your blood sugar numbers.
