More than "a little high sugar"
When a doctor says "prediabetes," many people hear "my sugar is a little high" and move on. But prediabetes is an important warning sign. It means your body is starting to struggle with how it handles blood sugar.
It's also more common than most people realize. The CDC estimates that about 115 million American adults, more than 2 in 5, have prediabetes, and most of them don't know it.
The good news: prediabetes is a stage, not a sentence. Understanding what's happening inside your body is the first step to changing it.
How your body uses blood sugar
When you eat, your body breaks carbohydrates down into sugar, called glucose. Glucose travels through your blood and fuels your cells.
To get inside those cells, glucose needs help from insulin, a hormone made by your pancreas. Insulin works like a key. It unlocks your cells so sugar can move out of your blood and be used for energy or stored for later.
When the lock gets sticky
With insulin resistance, the key still exists, but the lock gets sticky. Your muscles, liver, and fat cells stop responding well to insulin.
At first, your pancreas works overtime and makes extra insulin to force the door open. Because of that, blood sugar can look normal for years while the problem quietly builds. Eventually, the pancreas can't keep up, and blood sugar starts to rise. That's prediabetes.
Dr. Kalra often compares it to two people who each earn $5,000 a month. One manages the money well: bills get paid and savings grow. The other watches it slip away. Same income, very different outcome. Blood sugar works the same way. The real question isn't only how much sugar is in your blood. It's how well your body puts it to work.
The path from normal to diabetes
Prediabetes usually develops in stages:
- Normal blood sugar control
- Insulin resistance, often with no change in blood sugar yet
- Prediabetes, when blood sugar rises above normal
- Type 2 diabetes
Insulin resistance can build for 5 to 10 years before a type 2 diabetes diagnosis. That long runway is exactly why prediabetes is such an important window. The earlier you step in, the more you can change.
Signs your body may be asking for attention
Most people with prediabetes have no obvious symptoms. Some notice:
- Low energy that doesn't lift
- Weight gain around the midsection
- Strong sugar cravings or foggy thinking
- High blood pressure or high blood fats (triglycerides)
- Skin tags or darker skin on the neck
None of these proves anything on its own. But if several sound familiar, it's worth a closer look.
What drives insulin resistance?
Insulin resistance usually comes from a mix of factors, including:
- Deep belly fat around the organs, which causes inflammation that makes the lock even stickier
- Low muscle mass, since muscle is one of the body's biggest users of blood sugar
- Inactivity and long stretches of sitting
- Poor sleep and ongoing stress
- Fatty liver disease, which is closely tied to insulin resistance
- Family history and age
Two people can weigh the same and have very different metabolic health. That's why the scale alone doesn't tell the full story.
Prediabetes is a window, not a verdict
Prediabetes doesn't mean you will get type 2 diabetes. It means you have time to act. Better nutrition, more movement, stronger muscles, better sleep, and less stress can all help your body respond to insulin again. For some patients, medication is also part of the right plan.
