Why is it that when I run or exert myself, I can taste blood in my mouth, I feel shaky and out of breath?

It could be a couple of things you may have low blood sugar another thing is you may have low blood pressure and you are over exerting yourself. Or you could have something totally different.

Feeling out of breath isn't very abnormal when you're exerting yourself greatly. If you feel shaky as in trembling muscles, that could be ordinary fatigue. You could also be experiencing some hypoglycemia.
