Kim Kardashian Calls in a Pro to ... Avoid Pregnancy Health Risk

6/7/2015 1:00 AM PDT

Kim Kardashian is doing everything she can to avoid a serious complication with her second pregnancy ... including bringing in someone to keep her on a strict diet.

We're told Kim suffered from a high-blood pressure disorder called preeclampsia when North was in the oven. Only 5-8% of pregnant women get it, but doctors say its likely to reoccur ... so, Kim's taking action. 

Our Kardashian sources tell us she hired a nutritionist to devise a weekly meal plan with two key rules – lots of water and a low sodium intake. One big change -- KK started each day of her first pregnancy with a donut, but this time she’s reaching for protein shakes.  

Kim's hoping to avoid symptoms like swelling, headaches and changes in vision ... by sticking to the plan.

Sounds like Kanye might be off the hook for those late night craving runs.
