So i fainted at work, and now i'm scared that people might think that i have an eating disorder.?

the thing is that i didn't have breakfast on the morning and when i got to work there were like a zillion people and running around place made me tired and my blood pressure dropped down and i fainted in the kitchen, People were asking me if i hadn't eaten for a long time and stuff like that, if they ask me again what should i say i don't want them to think that i am sick with an eating disorder or anything like that.?

Have you given them any reason to even suspect before fainting that you may have an eating disorder?

Because if not then I would always ask when the last time someone had eaten if they fainted when I was around?

It is just a natural thing to ask as most people will faint due to a drop in BP due to not eating breakfast or lunch.

If you are really worried about the fact they may think you have an eating disorder then tomorrow when you go into work say "Thank you so much for yesterday. I have learnt my lesson. Eat breakfast!"
That should put their concerns at rest. And your's as then they know it was a once off thing.

just tell them the truth.
they should believe you, unless you were to faint again.

Tell them the truth.

It can be caused by low blood sugar and if you drink something with sugar will be fine.Say forgot my caffeine rush

tell them you don;t if they ask explain what happened
