15 Complications Linked To Prediabetes

Prediabetes doesn’t come with flashing signs or obvious symptoms—that’s what makes it so dangerous. Often called a silent precursor to type 2 diabetes, it means your blood sugar levels are higher than normal but not quite in the diabetic range. Many people dismiss it as a “not yet” diagnosis, but prediabetes is far from harmless. In fact, it can quietly set the stage for serious health issues long before diabetes is officially diagnosed. Studies show that up to 90% of those with prediabetes don’t even know they have it. That’s why early detection and lifestyle shifts are critical. Testing is especially important if you’re over 45, have a family history of diabetes, or struggle with high blood pressure or weight. To help you understand what’s really at stake, we’ve expanded our list to 15 Complications Linked to Prediabetes—each one a powerful reason to take action now, not later.

1. Progression To Type 2 Diabetes

Progression to type 2 diabetes is the most common complication of prediabetes. While prediabetes doesn't normally produce symptoms, several symptoms may develop in patients who are progressing to type 2 diabetes. For example, patients may experience darkened skin on their knuckles, knees, neck, or elbows. If increased thirst, blurred vision, fatigue, or frequent urination (more than eight times per day) develop, this suggests patients have most likely progressed to the diabetic range. To slow down or eliminate the risk of progression to type 2 diabetes, patients should speak with their healthcare provider about weight loss, dietary changes, and exercise plans that may help. Some communities have special support groups dedicated to preventing diabetes in patients struggling with prediabetes.
