I had my surgery one week ago today. (sleeved dec. 6th) I had some yogurt for breakfast. about a half hour later-watery stools. This is the 3rd time this has happened after having dairy. Since I have never had this problem before-am I becoming lactose intolerant?

Could definitely be lactose intolerant. I was able to still eat yogurt and some cheeses, but milk and whey protein were out. At 1-3 weeks out, I still had watery bms, so I couldn't attribute it to anything I was "eating". I also got horrific gas, and cramping when the lactose intolerance kicked in.
