Great info, Just1More! I had not seen low BP associated with floaters. I have some type of floaters chronically, but have occasionally been experiencing bright light "floaters." I wonder if it's related. They're definitely not a HIGH BP issue because mine has been lower than ever before in my life!
Low BP is very relative, as even when you're at a "safe" level, you could be at a sub-optimal level for you. My sister has been fighting dangerously low BP (and heartrate - she ended up with a pacemaker at 30) due to cardiac issues. She would work very hard to keep her BP above whatever number the doctors said, but still felt awful. Now, she's figured out where her *optimal* levels are (a good bit higher), and feels SO much better when she's at the right spot. Even in the last few months, I've figured out that when it gets sub-optimal I feel rotten, even though it's still above 90/60.
I have read that anemia can be a factor in low BP issues - both iron and B-vitamin anemia. Taking Floradix will give you good sources of both iron and b-vitamins and may help a lot. Also, salt is definitely important with low BP. When my sister feels bad, she drinks a full-salt V8 or full-sodium bouillon to help it get back up. Rest is also important. I know I accidentally mixed up the perfect low-BP storm the other day by being very hungry, a bit dehydrated, being on my feet for a long time, and, of course, being pg on top of it. I felt very woozy and a few minutes later my BP was 102/69 - super low for me, and I was already feeling better because I was sitting down. Resting and eating helped and I felt fine.
I know my sister has adrenal fatigue which also causes low BP, and I also have the adrenal issues (hers are worse). I'm not sure if that's why my BP is so low this pregnancy (but it's better than it being too high!). If you continue to experience problems with it post-pregnancy, keep in mind that the adrenals can get totally shot in pregnancy and long-term effects could be adrenal fatigue.
