Once upon a time is how I'd like to start this, but it isn't a cinderella story. Not long after getting married, but before having kids I was diagnosed with Orthostatic Hypotension. Huh, what? Mayo Clinic says:
Orthostatic hypotension — also called postural hypotension — is a form of low blood pressure that happens when you stand up from sitting or lying down. Orthostatic hypotension can make you feel dizzy or lightheaded, and maybe even faint.
Orthostatic hypotension is often mild, lasting a few seconds to a few minutes after standing.
The thing is that it only took numerous doctor visits and three specialists in different areas to diagnose. It took a while to figure out how to maintain my blood pressure high enough so I wouldn't white out or faint when I stood up. First there was medication then I altered my diet so I could do it without medication (eat more salt, eat more salt...and after over a decade I still have to remind myself daily to eat more salt). I was fine for years and years.
Now, all of a sudden it's happening again. Only it is happening not only when I change positions, but also when I run. Talk about frustrating! I had my blood work done to eliminate some medical-type-things that could be causing the light headedness. I'm healthy with all my numbers in the normal range except vitamin-D. So, now I'm taking vitamin-D. I have a follow-up doctor appointment in March and I hope to figure out what is going on.
This doesn't affect my life all that much, but I don't want to push myself running (distance or speed) until I get some answers. If last weekend's race is any indicator, I'm fine with a few miles, but once I start adding on more miles I have more troubles keeping my electrolytes level, which in turn allows my blood pressure to drop enough so I get light headed. FRUSTRATING!!! So, who knows what my running will be like this year. Once I get some answers and stop getting light headed while I run then I'll get back to longer distances.
FWIW, I was fine running my 2 miles this morning on my squeaky treadmill.
