The Bottom Line

Nighttime symptoms can sometimes provide clues that your blood sugar deserves attention.

Frequent urination, excessive thirst, restless sleep, sweating, nerve symptoms, unusual hunger, blurry vision, leg discomfort, and persistent fatigue can all occur in people with diabetes—but none of these symptoms proves the diagnosis on its own.

If several symptoms are happening together or getting worse, a simple blood test can provide much more useful information than trying to diagnose diabetes based on symptoms alone.
