Nighttime can make blood sugar changes easier to notice because the body is resting and there are fewer distractions. Waking up to urinate, feeling extremely thirsty, sweating during sleep, tossing and turning, feeling tingling in the feet, or waking up exhausted may all be clues that blood sugar is not well balanced.
These symptoms do not automatically mean diabetes. Many other conditions can cause similar problems, including dehydration, caffeine, urinary tract infections, menopause, sleep apnea, stress, medication effects, kidney problems, and hormonal changes. Still, if these signs happen repeatedly or appear together, it is wise to speak with a healthcare professional and ask whether blood sugar testing is needed.
