A patient sits across from me holding a lab printout, and one word on it has already done its damage: prediabetes. They heard "diabetes" and stopped listening. In their head they are already picturing insulin, finger sticks, and a list of foods taken away. So the first thing I tell them is the part the printout leaves out. Prediabetes is not a verdict, and for most people it is not permanent. It is a warning light that switched on early enough to do something about. That is the whole reason we measure it. We want to catch it right here, while it can still be turned around.
Roughly 1 in 3 American adults have prediabetes, and more than 8 in 10 of them have no idea they do. It rarely causes symptoms. Most people find out at a routine physical, and plenty never find out at all. That is exactly why a yearly visit with the right bloodwork is worth the trouble.
What the number actually means
The clearest way we measure this is the A1C, a single blood test that estimates your average blood sugar over the past two to three months. Unlike a one-time glucose reading, you cannot game it by skipping breakfast that morning. It shows the trend, not the moment.
- An A1C below 5.7% is in the normal range.
- An A1C of 5.7% to 6.4% is prediabetes. Elevated, but not yet diabetes.
- An A1C of 6.5% or higher, confirmed, is in the diabetes range.
Prediabetes means your body has started to struggle with insulin, the hormone that moves sugar out of your blood and into your cells for energy. Your cells have grown a little resistant to it, so sugar lingers in the bloodstream. Left alone, that resistance usually gets worse. Caught now, it can often be slowed or reversed.
The window is mostly made of small things
When patients imagine reversing prediabetes, they picture a punishing diet and an hour at the gym they will never keep up. The research points somewhere gentler and more lasting. The two things that move the number most are losing a modest amount of weight, often around 5 to 7% of what you weigh now, and moving your body regularly. Neither one asks for perfection.
On the plate, we are not chasing a trendy diet. We cut back on the things that spike blood sugar fastest, like sugary drinks, white bread, and packaged snacks, and we build meals around vegetables, fiber, and lean protein. For a lot of people, just trading soda and juice for water moves the needle on its own. The goal is a way of eating you will still be doing a year from now, not a two-week sprint.
Movement helps in its own right. When you walk, your muscles pull sugar straight out of your blood without needing as much insulin to do it. A brisk 30-minute walk on most days is genuinely powerful, and even a short walk after dinner can soften the spike that meal would otherwise cause. You do not need a gym membership or a running habit. You need something that fits your joints and your schedule well enough that you actually keep doing it.
Sleep and stress belong in this conversation too. Both short sleep and ongoing stress push blood sugar up through hormones like cortisol, and both are things we can usually do something about once we name them.
When lifestyle is not the whole answer
Sometimes lifestyle changes are not enough on their own, or your risk is high enough that we do not want to wait and see. For some patients, especially those with a higher A1C or a strong family history, a medication like metformin is a reasonable, well-studied option alongside everything above. We decide that together, based on your whole picture, and it is never automatic. Taking metformin does not mean you failed at the lifestyle part. It is one more tool when the situation calls for it.
How we work through it at Divine Care Services
A prediabetes result is the start of a conversation, not a leaflet handed to you on the way out. We confirm the number, look at the rest of your bloodwork like your cholesterol and kidney function, and talk honestly about what is realistic given your life. Then we build a plan you actually have a shot at following and recheck the A1C in a few months. If it is working, you see the proof in your own numbers. If it is not, we change the plan.
That recheck loop is what chronic care really is, and it is why seeing the same provider matters. I am not reading your chart cold every visit. I remember what we tried, what stuck, and what got in the way, so we can adjust one thing at a time instead of starting from scratch.
A prediabetes result is a head start. Let us build the plan while the window is still open.
