Occasional nighttime urination can happen to anyone, especially after drinking a lot before bed. But if it becomes a regular pattern, especially with thirst or fatigue, it should be checked.

Waking up with a dry mouth or strong thirst may happen when the body loses extra fluid through frequent urination. Some people keep water beside the bed because they wake up thirsty again and again.
