Then there was the guy who told his doctor the light came on automatically every time he went into the restroom at night. The doctor talked to the man’s wife about it and she said, “Darn! That means he is peeing int he refrigerator again!”

Other factors...waking up to use the bathroom can be connected to sleep apnea if you aren’t using a machine. Kidneys shut down based on sleep as per my therapist
Waking up and not being able to go to sleep can be insulin issue even for non diabetics. I wore a continuous monitor. I woke up when my insulin moved down. If I got up and ate something I could go back to sleep.
