Room temperature, medications, hormonal changes, infections, alcohol, and several other factors can contribute to night sweats.
However, episodes of sweating can also occur when blood glucose becomes too low, particularly in people who use certain diabetes medications.
Repeated unexplained night sweats should therefore be evaluated rather than automatically attributed to diabetes.
4. Restless or Interrupted Sleep
Changes in blood glucose can affect how a person feels throughout the night.
Thirst, frequent urination, sweating, hunger, or other symptoms may repeatedly interrupt sleep.
As a result, someone may wake up several times and feel exhausted the following morning.
5. Feeling Hungry During the Night
Unusual nighttime hunger can sometimes accompany changes in blood glucose.
Some people may wake up feeling intensely hungry even after eating dinner.
There are many possible explanations for nighttime hunger, so this symptom alone does not mean someone has diabetes. But when it occurs alongside other warning signs, it is worth mentioning to a healthcare professional.
6. Tingling or Numbness in the Feet
Persistently elevated blood glucose can damage nerves over time.
One possible consequence is peripheral neuropathy, which may cause sensations such as tingling, burning, numbness, or pain in the feet and legs.
These sensations can become particularly noticeable when a person is lying still in bed.
