Unexpected sweating at night may relate to nocturnal hypoglycemia episodes or peripheral nerve dysfunction.
9. Nighttime Hypoglycemia Symptoms
For those on insulin or certain diabetes medications, blood sugar may dip too low overnight. Signs include nightmares, sweating, rapid heartbeat on waking.
10. Nausea or Gastrointestinal Discomfort
Hyperglycemia or erratic blood sugar levels can lead to nausea or an unsettled stomach—even mid-sleep or upon waking.
11. Dry or Itchy Skin at Night
High blood sugar can dehydrate your skin, causing itchiness, especially overnight when temperature and humidity change.
12. Recurrent Infections or Yeast Growth
Nighttime thrush or fungal irritation (e.g., around feet or genital area) can occur due to elevated glucose creating a breeding ground for yeast.
13. Nighttime Restless Legs Syndrome (RLS)
A neurological symptom sometimes associated with diabetes, RLS can surface as an uncomfortable urge to move the legs—especially at rest or during sleep.
14. Confusion or Difficulty Concentrating Upon Waking
Both severely high overnight glucose and hypoglycemia can cause cognitive symptoms upon waking: confusion, fogginess, or irritability.
15. Waking with Dry Mouth or Dehydration
Even mild dehydration from nocturnal urination or poor overnight hydration may manifest as dry mouth upon waking.
