I almost got sent IP for an ED in 2020 and I'm not underweight and the only reason she didnt admit me was because I was drinking water. And I was still eating too just restricting and eating safe foods which they thought was enough to send me for an assement. They were just being jerks. I got sent to IOP instead.
The dumb thing is my surgeon was really happy with my weight loss and said we could hold off on a surgery until I lost more.
