High blood glucose can cause the kidneys to excrete more glucose and water, increasing urine production.
Persistent nighttime urination can also be caused by urinary tract problems, prostate enlargement, medications, sleep disorders, or excessive evening fluid intake.
2. Unusual Thirst During the Night
Some people wake up with an extremely dry mouth or a strong desire to drink water.
If this happens repeatedly alongside frequent urination, elevated blood glucose is one possible explanation.
The body may be losing more water through urine than usual, causing thirst to increase.
However, persistent thirst can also occur because of dehydration, certain medications, high-salt meals, fever, or other medical conditions.
3. Night Sweats
Waking up drenched in sweat is another symptom that should not simply be attributed to diabetes.
For people taking insulin or certain glucose-lowering medications, low blood glucose during the night can trigger sweating, shaking, a racing heartbeat, hunger, anxiety, or nightmares.
Night sweats can also have many other causes, including menopause, infections, medications, alcohol, anxiety, and sleep disorders.
If someone with diabetes repeatedly wakes up sweating or confused, checking glucose levels and discussing the episodes with a healthcare professional is important.
