Prediabetes: Causes, Symptoms, and Prevention
What is Prediabetes?
Prediabetes means your blood sugar levels are higher than normal but not high enough to be classified as diabetes. Think of it like a warning light on your car’s dashboard—it signals you to take action before a bigger health issue arises.
How Does Prediabetes Happen?
When you eat food, your body breaks it down into sugar (glucose), which travels through your bloodstream to provide energy to your cells.
Your body produces insulin, a hormone that acts like a key to unlock your cells and let sugar enter.
With prediabetes, this process starts to break down:
✅ Your body might not make enough insulin
✅ Your cells become resistant to insulin (called insulin resistance)
As a result, excess sugar stays in your bloodstream instead of moving into your cells, where it belongs.
How Common is Prediabetes?
📍 In the United States
- About 96 million American adults have prediabetes
- That’s 1 in 3 adults
- 50% of people over 65 have prediabetes
📍 The Awareness Gap
- 8 out of 10 people with prediabetes don’t know they have it
- That’s about 78 million Americans unaware of their condition
📍 Worldwide
- 541 million adults globally have prediabetes
- That’s about 1 in 10 adults worldwide
Signs and Symptoms of Prediabetes
Most people with prediabetes don’t experience any symptoms, which is why it’s often called a “silent condition.”
Possible Warning Signs:
✔ Dark skin patches in neck folds, armpits, or groin
✔ Feeling unusually tired or fatigued
✔ Increased thirst
✔ Frequent urination
🔹 If you have blurry vision, numbness in your feet, or extreme fatigue and thirst, prediabetes may have progressed to diabetes.
What Causes Prediabetes?
Risk Factors You Can’t Change:
❌ Age: Risk increases after age 35
❌ Family History: Higher risk if parents or siblings have type 2 diabetes
❌ Race & Ethnicity: Higher risk for Black, Hispanic/Latino, Asian, Pacific Islander, and Native American communities
❌ Medical History: Women with gestational diabetes or PCOS (Polycystic Ovary Syndrome) have a greater risk
Risk Factors You Can Change:
✅ Weight: Excess weight, especially around your belly, is a major risk factor
✅ Physical Activity: Lack of exercise makes your body less effective at using insulin
✅ Diet: Sugary drinks and processed foods increase prediabetes risk
✅ Sleep: Poor sleep or sleep apnea affects how your body processes sugar
✅ Smoking: Tobacco use can cause insulin resistance
