I went to the gym earlier and noticed a girl there who I have seen a few times in the past two weeks. She's painfully thin, but I obviously cannot diagnose any kind of eating disorder because I don't know her.
The past few times I've seen her push herself quite hard (I admit I do watch her only because the first time I noticed her I was shocked by the size of her frame) running to the point of exhaustion on the treadmill.
The same happened today, and when I finished, I ended up walking behind her toward the changing rooms. She looked quite unsteady and almost 'collapsed' onto a bench in the changing rooms. I got unchanged (kept looking over at her as we were the only two in there) and the whole time she was leant forward with her head between her legs, like you'd do if you were feeling faint. As I left, I touched her shoulder and asked if she was ok, but she just waved me away. She looked dreadful, no colour in her face and obviously struggling to even speak.
I didn't want to meddle, but have been thinking about it all afternoon. Should I have said something to the gym staff? I assume they do some kind of induction/fitness assessment when new people join to ensure they're healthy enough to work out.
WIBU to not say anything?
