Skip to content One of the most common nighttime warning signs is waking up again and again to use the bathroom. When blood sugar is high, the kidneys try to remove extra glucose from the blood. This can pull more fluid into the urine and increase urination.
This may show up as one bathroom trip becoming two, three, or more. The sleep disruption can then leave you tired the next day. The CDC lists frequent urination among common diabetes symptoms, along with increased thirst, hunger, fatigue, blurry vision, and numbness or tingling in the hands or feet.
Occasional nighttime urination can happen after drinking a lot before bed. But if it becomes a pattern, especially with strong thirst or morning fatigue, it should be checked.
