can it be to low??

hi all
i had my 8th month check up yesterday with Dr.Mac, my blood pressure was 94/59
his nurse asked if i had any light headiness or feeling dizzy.. i said every so often but nothing to worry about..I also said my blood sugars have been droping like crazy, she said up my protien with snacks again..
but i was wondering could my blood pressure be to low for my body... i do get dizzy a lot and have the feeling of oh my gosh i'm going to black out..but never worried..
so i spoke to my mom and she said add salt to my diet.. WHAT i hate salt if its not in the food i'm not adding it.. i quite eating salt when i was like 14... so like i said if its not on my food before i buy it, its not going to make it on there..
but will this help, if i  add a little bit of salt? i don't want to feel spacey, so i'm not sure what to do..
just wondering is there  a to low for anyone? what dangours?
thanks
Annmarie

I would continue to monitor it daily..can you do that at home? That is boarderline of what is considered low...90/60. Maybe you should have a visit to see your PCP but I would want to see a weeks worth of #'s take am/pm first...JMO
