L.Z.
Hi L. - I had my gallbladder out when I was 23, which was odd because I didn't fit any of the profile characteristics the dr. told me about, but regardless, it was emergency surgery as I had gallstones and the gallbladder was inflamed and needed to come out! It's good that you have some foresight that this might be happening soon, making it easier to plan. Anyway, assuming you have laproscopic surgery (when they insert a thin tube in two or three small incisions and basically suck the gallbladder out), recovery time os not bad at all, about 10 days total in my experience. I have three very small incision areas, one on my belly button, one on my side, and one halfway between my chest and belly button. The fact that it wasn't a huge amount of "going under the knife" makes the recovery a lot quicker. It was hard to stand up straight the first few days, and there was some general pain and discomfort in my abdomen, but after about a week I was walking around normally and driving with no issue. I'd give yourself 10 days - 2 weeks or so to go back to work so you can fully chase the toddler you care for and pick her up, etc. I have a 3-year old too and I know how active she can be.
One last thing - I saw that you live in Cambridge. I had my surgery and both my kids at Mt. Auburn. If you are going there, you will be in great hands! Good luck!
