If there are 4 conditions when sleeping, or diabetes are approaching you

1. Numbness: High blood sugar affects circulation and nerves, causing numbness in the hands and feet, especially when sleeping.

2. Thirst: Despite sufficient fluid intake during the day, dry mouth and thirst occur at night due to fluctuations in blood sugar levels. High blood sugar stimulates the mouth, leading to dryness, and also disrupts metabolism, causing itchy skin during sleep.

3. Hunger: Feeling hungry even after a sufficient dinner may indicate elevated blood sugar levels. Excess glucose in the bloodstream cannot be digested and utilized by the body, resulting in insufficient energy supply and hunger.

4. Frequent urination: Normally, night-time urination occurs 0-2 times. However, high blood sugar levels can lead to frequent urination.
