DebLW 7 Posted January 15, 2013 I started my pre-op diet yesterday in anticipation of my 1/23 surgery. Today, I had a Protein shake for Breakfast and another for lunch. Beginning late this afternoon, I have had absolutely miserable diarrhea! I have never had a problem with dairy in my life, so I don't think it's lactose-related. I'm actually hoping that it's a brief bout of flu and not an intolerance to Protein shakes and powders......has anyone ever had this happen to them?

JerseyGirl68 1,172 Posted January 15, 2013 I seemed to have less of a tolerance for milk after surgery. I switched to Smart Balance/Lactose free and it has gotten much better. Share this post Link to post Share on other sites
kmb4me 4 Posted January 15, 2013 Hi, I seem to have this problem when I am drinking more than one shake a day. I think it is your bodies reaction to the sugar substitutes in a lot of these shakes. The same thing happens when I am at my mom's and I eat more than a few pieces of their sugar free candy.< /p> Share this post Link to post Share on other sites
clk 3,519 Posted January 15, 2013 Artificial sweeteners or yes, dairy. There's a huge amount of dairy in your diet if you're drinking two or more shakes a day - between the shakes and the fact that most people mix them with milk you can have a real issue. You can try finding a shake that has nothing artificial in it and see if that helps, or try mixing with a different liquid like Water, hemp milk, tea or coffee to see if that helps cut some of the reaction. Too many artificial sweeteners can cause dumping, especially if we're not used to eating them. ~Cheri Share this post Link to post Share on other sites
