Dizziness....
 

I have been struggling with eating for a while. Have issues with laxatives/diuretics/being sick.
Today for the first time after I made myself sick, I nearly fainted. Im not sure if it's lack of food - I dont think so though, im not eating a lot, but I am eating - or if it's more likely the action of making yourself sick? I didnt faint, just felt like I might and went dizzy and feel okay now, just wondered if anyone else had experience with this?

It could be something to do with the position you was in when you was making yourself sick, ever heard of a head rush?

If it passed pretty quickly it could have something to do with that. Technically a head rush is a brief fall in blood pressure, when you stand up quickly or change position too quickly - does that sound like it could be the cause?

i agree with grace i get this all the time i get head rushes quite alot at the moment and im eating regular amounts

Really it's likely to do with you not breathing at the same time and therefore you having a lack of oxygen going to your brain (which is worsened by your head position) along with vomitting casing your electrolytes to become imbalanced which can case severe damage and make you feel really ill along with you also not having enough energy in you too.

Really I'd recommend you reading the ED Article. That may help you much more.
