Overview

Prediabetes is a condition in which blood sugar levels are higher than normal but not yet high enough to be classified as type 2 diabetes. It affects more than 96 million American adults — and the majority don't know they have it. Prediabetes is a critical warning window: with the right lifestyle changes, it is possible to reverse prediabetes and prevent or significantly delay the onset of type 2 diabetes.

Key Points

Prediabetes is defined as a fasting glucose of 100–125 mg/dL or an A1C of 5.7–6.4%.
Without intervention, up to 30% of people with prediabetes develop type 2 diabetes within 5 years.
Losing just 5–7% of body weight reduces the risk of progressing to diabetes by 58%.
Prediabetes typically has no symptoms — it is found on routine blood work.
Metformin may be prescribed for high-risk individuals in addition to lifestyle changes.

Signs & Symptoms

Usually no symptoms — prediabetes is detected through fasting glucose or A1C blood tests
Darkened skin in body folds (acanthosis nigricans) — a sign of insulin resistance
Mild fatigue or increased thirst in some individuals
Identified on routine screening at annual wellness exam
Often discovered alongside other metabolic findings: high blood pressure, high triglycerides, low HDL

Causes & Risk Factors

Insulin resistance — the body's cells don't respond efficiently to insulin
Excess body weight, especially abdominal obesity
Physical inactivity and a diet high in refined carbohydrates and sugar
Family history of type 2 diabetes
History of gestational diabetes, polycystic ovary syndrome (PCOS), or metabolic syndrome

Treatment Options

1Structured lifestyle program: 150 minutes of moderate exercise per week and dietary changes

2Weight loss of 5–7% of body weight — the most effective intervention for reversing prediabetes

3Low-glycemic, high-fiber diet with reduced refined carbohydrates, sugar, and processed foods

4Metformin for high-risk individuals (BMI ≥35, age <60, or history of gestational diabetes)

5Regular monitoring: A1C or fasting glucose every 6–12 months to track progress

When to See a Doctor

Ask about prediabetes screening at your next annual exam, especially if you are overweight, over 35, or have a family history of diabetes. If you have already been told you have prediabetes, schedule a follow-up to build a structured prevention plan — the window to reverse it is real and worth acting on.
