Diabetes Symptoms at Night: Top 7 Signs of High Blood Sugar That Get Worse After 10 PM
Many people with diabetes or prediabetes notice that their symptoms become more intense during the night. After 10 PM, hormonal changes, late meals, and reduced activity can cause blood sugar levels to rise. Recognizing these warning signs early can help prevent serious complications.
1. Frequent Urination During the Night
High blood sugar causes excess glucose to spill into the urine. This forces the kidneys to work overtime, leading to repeated trips to the bathroom after bedtime.
2. Extreme Thirst Before or During Sleep
If you feel very thirsty late at night or wake up needing water, it may be due to dehydration caused by high blood sugar levels.
3. Night Sweating
Unusual sweating during sleep can be linked to blood sugar imbalances. Both high and fluctuating glucose levels can trigger this symptom.
4. Difficulty Falling or Staying Asleep
High blood sugar can overstimulate the body, causing restlessness, frequent waking, or poor sleep quality.
5. Burning, Tingling, or Numbness in Feet
Nerve damage (diabetic neuropathy) often feels worse at night. Symptoms may include burning pain, pins-and-needles, or numbness in the feet and toes.
6. Dry Mouth and Throat
Waking up with a dry mouth, cracked lips, or throat irritation is a common sign of nighttime dehydration caused by high glucose levels.
7. Morning Fatigue and Brain Fog
Poor blood sugar control at night can leave you feeling exhausted, unfocused, or weak the next morning, even after a full night of sleep.
