Prediabetes is a warning sign that the body's blood sugar regulation is starting to slip. The good news is that it's often a turning point where changes can make a real difference.
What prediabetes means
Prediabetes is a state where blood sugar is higher than normal but not high enough to be classified as type 2 diabetes. It reflects growing insulin resistance — the body's cells responding less well to insulin, so glucose lingers in the blood. It's typically identified through blood tests a doctor orders, such as fasting glucose or A1C.
It's common and quiet
Prediabetes is strikingly widespread — by some estimates over a third of American adults have it, and most don't know, because it usually causes no symptoms. That silence is why routine check-ups and screening matter, especially for people with risk factors like excess weight, family history, or a sedentary lifestyle.
Why it's a pivotal moment
Prediabetes doesn't always progress to diabetes — and that's the encouraging part. Research on lifestyle programs has shown that modest, sustained changes can substantially cut the risk of developing type 2 diabetes, sometimes more effectively than medication. Those changes typically include:
- Losing a modest amount of weight if overweight.
- Cutting back on sugary drinks and refined carbohydrates.
- Getting regular physical activity.
- Eating more fiber from whole foods.
The role of drinks
Because sugar-sweetened beverages spike blood sugar and contribute to weight gain, swapping them for water or unsweetened drinks is one of the highest-impact changes for someone with prediabetes — one reason knowing a drink's real sugar content is so useful.
