Blood pressure still high almost 2 years postpartum?

I got preeclampsia and was induced at 37 weeks.

Last year at 9 months postpartum, I had my annual physical. I was still overweight at 5’5, 160 lbs. Prior to pregnancy, my BP was always 115-120/70-75. Very normal. At the physical, it was still 140/85. I figured it was probably because of my weight.

I’ve lost 12 lbs since (I’m 148, still working on it) and eating better, but my diastolic isn’t improving at all. My systolic is around 125ish but the diastolic remains at 85+.

Is this just a preeclampsia thing? Am I stuck with this?
