What are some of the nutritional modifications with pregnancy?
Baby needs you to consume a MINIMUM of 100g of carbs a day for neural tube development, so if you've been following the high protein/ low carb diet as most of us have, now's the time to stop. Continue to get plenty of protein and water in and add healthy fats if you've been avoiding those as well.
As for vitamin changes, I kept up my bariatric vitamin routine and simply added a prenatal on top of it, though I have the malabsorption factor where you do not, so that may not work for you.
Congrats on your pregnancy and best wishes for a happy, healthy 9 months!
I got pregnant with my first post op baby when I was 6 months out from my sleeve. I was mostly done losing, so I just kept eating what I already was plus I added in a few snacks. As pregnancy progressed, hydration became more of a struggle for me (this has been the case with all my pregnancies) so I needed a gatorade every evening just to keep the braxton hicks tolerable. Yes, it is lots of carbs, but my weight gain was fine, so it seemed like a fair trade off for the hydration. As for vitamins, I took two chewable target brand multi vites (generic flintstones) which have as much or more of everything in a prenatal, so I checked with my doc and they were fine with me continuing with that. I also took a calcium/D supplement. I'm currently 30 weeks into my 2nd post op pregnancy and this time my iron is low, so I've simply added an extra iron supplement to my routine. Otherwise, all my levels have remained fine despite an early post op pregnancy, nursing, and another pregnancy. Good luck!
