Is taking laxatives considered an eating disorder?

Last year around Christmas time, my sister was bulemic. She lives in another state, but when she came home for Christmas, she had to hide it, and it was really hard to, because we could hear her. This Christmas, I noticed she is not throwing up, but I was thinking she could be taking laxatives. She is in the bathroom every night going #2 and sometimes she is in there for a while. What do you think?

If she was making herself vomit on purpose and now she's taking laxatives on a regular basis..yes...most definitely another stage of her eating disorder.

It's used as a method of purging for bulimics...yes.
she could be. taking laxatives could be considered part of an eating disorder if they are being abused. especially if she has a history of bulemia.
If she's abusing laxatives, yes.
If she simply can't go to the washroom, no need to prance on her like a tiger.
Yes, it's part of an eating disorder if you take them daily to control weight loss.
