Dizziness, lightheadedness, and dehydration

I also have spells with lightheadedness.  It usually happens when I stand up.  Sometimes my vision goes completely black and and my head feels like it's going to spin right off my head!!  I journal my food and fluid intake everyday.  I always get my 64 oz of fluids and most times even more.  I aim for 100 grams of protein per day but some days I barely manage 70.
When I was in the hospital having my colon surgery my bp ran real low.  They could barely get it to register.  I just had all my labs done and everything was normal.
Glad you brought this up Bob because I hadn't really thought about it being dehydration.  My husband tells me I should be blonde sometimes so I thought I was just playing the part!! LOL!
Seriously, Great topic!!
