I cannot tell if you are currently pregnant or postpartum: My documented labile b/ps started at 26 weeks, although i had symptoms about 8 weeks prior to that. Postpartum labile b/ps: I delivered April 2010 and although I am not on Nifedipine or Labetalol anymore, I was for the first post partum year and still have labile b/ps. I started pregnancy at 90s/50s (a place I had been for as long as I can remember, because I ran 40 miles a week - 20 miles a week up until 26 weeks gestation and my PE), and now my "normal" is about 124/84 with elevations to the 140s/90s, when I am tired especially. My cardiologist asks me to keep track of my b/ps and to be careful about estrogen containing medications (eg. birth control pills for the most part, but later, if I wanted to help my menopause symptoms once I arrive there). He cannot tell me whether or not I will end up with permanent hypertension further down the line, but he will treat it aggressively knowing that i had PE (once we do decide to go down that road). He is not willing to treat the labile b/ps until we don't really call them labile anymore (meaning once I permanently elevate my blood pressures) - most of the reason being how labile hypotensive I was on 50mg (a half of the smallest dosage they make) of Labetalol. I definitely do feel my blood pressure changes, but am very aware of my body. I wonder in general how much of the population is labile (even at rest), and if because of our histories we are much more in tune and much more aggressive about treating it?
