Prediabetes
Blood sugar levels higher than normal but not yet diabetes.
Overview
Prediabetes is a condition where blood sugar levels are elevated but not high enough to be classified as type 2 diabetes. It's a warning sign that you're on the path to diabetes. About 1 in 3 adults has prediabetes, but most don't know it. The good news: prediabetes is reversible with lifestyle changes. Without intervention, it typically progresses to type 2 diabetes within 5-10 years. Prediabetes also increases risk of heart disease and stroke.

Detailed Treatment & Solutions
1WEIGHT LOSS
Losing just 5-7% of body weight (10-14 lbs for a 200 lb person) can prevent progression to diabetes. Focus on sustainable changes rather than crash diets.
2EXERCISE
150+ minutes per week of moderate activity (brisk walking). Both aerobic exercise and resistance training improve insulin sensitivity. Any movement is better than none.
3DIETARY CHANGES
Reduce refined carbs and added sugars. Increase fiber (vegetables, legumes, whole grains). Choose protein and healthy fats to stabilize blood sugar. Mediterranean diet is well-researched.
4MONITOR BLOOD SUGAR
Track fasting glucose and/or A1c regularly. Some people use glucose monitors to see how foods affect their blood sugar.
5SLEEP AND STRESS
Poor sleep and chronic stress worsen insulin resistance. Prioritize 7-8 hours of sleep. Practice stress management techniques.
6MEDICAL SUPPORT
Some doctors prescribe metformin for prediabetes prevention. Regular follow-up to catch progression early. Treat related conditions (high blood pressure, cholesterol).

Frequently Asked Questions
QCan prediabetes be reversed?
Yes! Prediabetes is often reversible with lifestyle changes. Studies show that losing 5-7% of body weight and exercising regularly can reduce diabetes risk by 58%. Some people return to completely normal blood sugar levels. The key is making changes before progression to diabetes.
QHow do I know if I have prediabetes?
Prediabetes usually has no symptoms—you need a blood test. Fasting glucose of 100-125 mg/dL or A1c of 5.7-6.4% indicates prediabetes. Get tested if you're over 45, overweight, have family history of diabetes, had gestational diabetes, or have PCOS.
