Pre-eclampsia risk due to low BMI?

[ruruuu99]

Hello, so I'm pregnant with my second and registered myself with the same hospital where I had my first. On the first appointment, all the routine tests were done and my blood pressure was checked - everything was fine. They found me on the system so have all of my records.

Minutes after leaving the hospital, my midwife called to say that she forgot to mention that because my BMI is on the low side (18), I'm apparently at risk of pre-eclampsia?

This really stunned me because I was literally the same weight when I had my daughter and no one ever mentioned the risk of pre-eclampsia.

I searched online and could not find anything that mentioned a correlation between low BMI and pre-eclampsia - it's only associated with a high BMI.

She also advised that due to this risk, I should start taking aspirin. I definitely don't feel comfortable doing that as it seems completely unnecessary, bearing in mind all of my tests were fine. Nothing has changed weight or health-wise since the first pregnancy, so am not sure where this is coming from.

Has anyone experienced this, where they've had a low BMI and were told that they're at risk of this condition?

Thanks!

I assume they've discovered a new link.

What exactly do they want you to do with this info though? You get tested on every visit.

I had pre eclampsia with a mid range bmi.

The guidance and advise changes constantly but that's all it is 'guidance and advice' no-one will force you to take aspirin if you don't want to.

@ruruuu99 you seem to be well informed and have done your research.

This study shows, as you have seen;

1. Conclusions

Class I and II obesity are significantly associated with preeclampsia with severe features. Class I obesity is significantly related to late-onset severe preeclampsia, whereas class II obesity is associated with both early- and late-onset preeclampsia.

Perhaps, if you wanted to, challenge her and ask for her evidence?

Sounds odd to me. I would have thought the main risk in early pregnancy would be low blood pressure and feeling faint. Mine was 90/45.
