4. A sudden, gnawing hunger in the middle of the night
If your stomach is rumbling and you feel hungry in the middle of the night, your body may be having trouble regulating glucose. Unstable blood sugar can cause feelings of hunger, even after a large, balanced dinner.
5. Insomnia that becomes chronic
Do you have trouble falling asleep or do you keep waking up? Excess sugar disrupts the secretion of melatonin, the sleep hormone, preventing your body from entering restorative rest.
6. Persistent morning fatigue
Do you wake up exhausted after eight hours of sleep? That's not normal. Poor blood sugar balance prevents your body from recovering properly, leaving you feeling tired and fatigued throughout the day.
7. Pain or tingling in the legs
Tingling, numbness, or nighttime pain in the lower limbs can signal nerve damage caused by chronic excess sugar. This symptom is common in people with diabetes.
8. Blurred vision upon waking
If your vision is blurry at night or first thing in the morning, it could be a sign of fluctuating blood sugar levels. High sugar temporarily changes the shape of the lens of your eye, which impairs the sharpness of your vision.
