Did you know that when you are not drinking enough water, you are straining your heart and vascular system, and depriving your brain of good blood flow?
Low blood volume can cause orthostatic hypotension. This is when there isn't enough blood getting to the brain when you change position from lying down to upright. This can lead to dizziness, confusion and falls, and often happens in the elderly. But it can happen in people with MS, too. Orthostatic hypotension is well-documented in MS and has been a mystery for researchers.
When women are pregnant, their blood volume increases dramatically. This sends blood pumping throughout the body.
Thinking about blood volume in terms of CCSVI treatment and restenosis of veins has been very interesting to me. If angioplasty is returning good, open routes of flow, but the body is not able to compensate by providing adequate blood volume, then these opened vessels will not have the necessary pressure to remain opened. And the areas of prior stenosis might re-collapse, just like an old garden hose with low flow.
I hope to bring this avenue of discussion to the doctors. Perhaps aftercare needs to include additional hydration, salt intake, maybe even intravenous fluids--all to keep blood levels adequate. Inactivity and remaining in the supine position increase hypovolemia--therefore, movement, exercise and upright activities would encourage blood flow and blood volume. Something to think about as we move forward with CCSVI research in 2011.
With wishes for good flow in the New Year!
