Are nose bleeds, random bruising, and skipping lunch intrinsically linked?

For maybe about the last month, i've stopped eating lunch or snacking completely. I eat a small breakfast and a mediumish dinner and thats it. Recently, I've started getting bruises on my body for no reason at all. And they really hurt too but I haven't done anything to cause them. I also have been getting really bad nose bleeds, lots of blood... ewww.. And I never get nose bleeds, only a couple times in my life time until now. are these in anyway linked? Is it because of my eating?
