As a sleeve patient, my doc had me crushing pills and/or taking chewables for 3 weeks post surgery to prevent anything from getting stuck in the stitches. Not going to lie, this was the worst, most horrific, disgusting and vile aspect of the entire process. The only saving grace was the multi vitamin gummies - they are yummy and a nice reward for gagging down the pills tasting of mouthfulls of battery acid laced with cat urine. I'd double check with your doc to see if you also need to crush or use chewables, and/or if you can use gummy varieties.
And in my case, I immediately took vitamins & continued my regular medication post surgery. Your doc will also be very specific on this.
