Dehydration?

I thought I was drinking enough liquids. Then yesterday, I almost fainted at work and my blood pressure was 160/108. I was hot, sweaty, shaking and the world was getting fuzzy. I am going to the doctor today but could it really be dehydration?

it could also be lack of b12 do you take your b12? I only have to take once a week sublingual. Some people take it everyday. did you eat before this happened it could of been the dumping if you had rny. My doctor say at least 64oz of water a day. Do you have diarreah that could cause dehydration. glad you are going to the dr. make sure you let us know how you are doing.

I had this same problem a few different times, less the sweat. My doctor said I wasn't eating enough. Yes I was getting my protein in but my body still needed to eat more carbs, sugars, etc.....I started eating more and it went away....Anyways just my experience, everyone is different!
