Complications

The most serious consequence of prediabetes is progression to type 2 diabetes. That's because type 2 diabetes can lead to:

• High blood pressure
• High cholesterol
• Heart disease
• Stroke
• Kidney disease
• Nerve damage
• Vision problems, possibly loss of vision
• Amputations

Prediabetes has been linked with unrecognized (silent) heart attacks and can damage your kidneys, even if you haven't progressed to type 2 diabetes.
