Night Emotional Eating

I would like some insight into this situation.
Waking up in the middle of the night and binge or eat.
It makes her stomach feel better, she says.
Now I am familiar with the triggers and urges, but if you are getting up every night and stuffing your face, what could be going on?
She goes back to sleep after the binge.
It’s about 2 am in the morning.
Thank you!
