Introduction
Pre-diabetes is a condition where blood sugar levels are higher than normal but not yet high enough to be diagnosed as diabetes. This stage is crucial for preventing the progression to type 2 diabetes. Understanding the concept of prediabetes and recognizing early symptoms can help take effective measures to prevent the condition from worsening.

Understanding the Three Stages: Normal, Pre-diabetes, and Diabetes
The progression from normal blood sugar levels to diabetes typically occurs in three stages: normal, Pre-diabetes, and diabetes.
- Normal Blood Sugar Levels: A healthy individual typically has fasting blood sugar levels below 100 mg/dL and post-meal blood sugar levels below 140 mg/dL.
- Prediabetes: Blood sugar levels are elevated but not yet in the diabetes range. Fasting blood sugar levels range from 100-125 mg/dL, and post-meal blood sugar levels range from 140-199 mg/dL.
- Diabetes: Diagnosed when fasting blood sugar levels are 126 mg/dL or higher, or post-meal blood sugar levels are 200 mg/dL or higher.
What is Prediabetes?
Prediabetes is a metabolic condition indicating higher-than-normal blood sugar levels, but not high enough to be classified as diabetes. People with prediabetes have a significantly increased risk of developing type 2 diabetes in the future.
- Blood Sugar Level Range: Fasting blood sugar of 100-125 mg/dL, or post-meal blood sugar of 140-199 mg/dL.
- Risks: Without intervention, about 70% of individuals with prediabetes will progress to diabetes within a few years.
Early Symptoms of Prediabetes
Prediabetes often has no obvious symptoms, but some people may experience mild signs that indicate elevated blood sugar levels.
- Fatigue: Persistent fatigue can result from fluctuating blood sugar levels.
- Increased Thirst and Frequent Urination: Elevated blood sugar levels increase urine output, leading to frequent thirst and urination.
- Blurred Vision: Changes in blood sugar levels can temporarily affect the lens of the eye, causing blurred vision.
- Weight Changes: Some individuals may experience unexpected weight loss.
How to Identify Prediabetes?
Identifying prediabetes requires medical testing, particularly blood sugar tests.
- Fasting Blood Sugar Test: Measures blood sugar levels after an overnight fast.
- Glucose Tolerance Test: Measures blood sugar levels two hours after consuming a sugary drink.
- Hemoglobin A1c Test: Reflects average blood sugar levels over the past 2-3 months.
Conclusion
Prediabetes is a critical window for diabetes prevention. Regular screening and early symptom recognition can lead to early intervention, significantly reducing the risk of developing diabetes.
