ConditionICD-10: R73.03

Prediabetes

Prediabetes is elevated blood sugar that has not yet reached the diabetes threshold (A1c 5.7–6.4% or fasting glucose 100–125 mg/dL). ~96 million Americans have prediabetes and 80% don't know it. The good news: with diet, exercise, and sometimes medication, progression to type 2 diabetes can be slowed or reversed entirely.

Key facts

•96 million US adults have prediabetes (CDC)
•15–30% progress to type 2 diabetes within 5 years without intervention
•Lifestyle intervention reduces progression risk by 58% (DPP study)
•GLP-1 medications reduce progression risk by 60–70% in clinical trials
•Insurance coverage for prediabetes is limited — most plans require T2D diagnosis

Why GLP-1 medications

For high-risk prediabetes patients (BMI ≥ 25, family history, gestational diabetes history), GLP-1 medications combined with diet + exercise can normalize blood sugar. Wegovy 2.4 mg has FDA approval for weight management — secondary effect lowers A1c and improves insulin sensitivity. Off-label use in pure prediabetes is increasing.

Common symptoms

Usually asymptomatic — detected only on lab work
Skin tags or dark patches (acanthosis nigricans) in some patients
Some patients report fatigue or mild thirst (rare in prediabetes)

How prediabetes is diagnosed

A1c 5.7–6.4% OR fasting plasma glucose 100–125 mg/dL OR 2-hr OGTT 140–199 mg/dL. CDC recommends screening every 3 years starting at age 35, or earlier if overweight + risk factors. Many primary care visits now include automatic A1c screening.

Treatment options

Diabetes Prevention Program (DPP)

CDC-recognized lifestyle program — 22 weekly group sessions + 1-year maintenance. Goal: 5–7% body weight loss + 150 min/wk exercise. Reduces T2D risk by 58%. Now covered by Medicare and most insurance.

Metformin

Off-label for prediabetes prevention. Reduces T2D risk by ~31% (less than DPP but easier to maintain). Best for BMI ≥ 35, age < 60, gestational diabetes history.

GLP-1 medications

Off-label for pure prediabetes. Reduces progression by 60–70%. Cost barrier — most insurance excludes for prediabetes-only diagnosis.

Lifestyle changes alone

For low-to-moderate risk: targeted diet + exercise without formal DPP. Less effective but appropriate for younger, slimmer patients.

Lifestyle & self-care

Lose 5–7% body weight if overweight (most powerful intervention)
150+ min/week moderate exercise (walking briskly counts)
Reduce sugary drinks, refined carbs, ultra-processed foods
Increase fiber (25g/day women, 38g/day men)
Limit alcohol — empty calories that destabilize blood sugar
Re-test A1c every 6–12 months to track progress

When to see a doctor

Make an appointment if you have:

→Age ≥ 35 (CDC screening recommended)
→BMI ≥ 25 + sedentary lifestyle
→Family history of T2D
→Gestational diabetes during pregnancy
→Polycystic ovary syndrome (PCOS)
→High blood pressure or cholesterol
