The Bottom Line
Nighttime symptoms can sometimes provide clues that 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 them 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 guessing from symptoms alone.
