Easy bruising Anemia?

Curious if anyone knew anything about this. My girlfriend bruises quite easily and they are dark deep bruises. Most of the time she doesn't even know where they came from. At times she gets dark circles under her eyes which i believe is contributed to low blood pressure. If she gets too hot her blood pressure drops. Kinda has me worried so just wondering what could be done to help. Thanks

It sounds like she has autonomic dysfunction. The bruising could be unrelated and due to a deficiency, but there's a chance it is related to the other problems, in which case the underlying issue could be a connective tissue disorder. Autonomic dsyfunction is somewhat treatable.
