I have recently been trying to drink a protein shake in the morning. I get about 4-5 sips down and I cannot get to the bathroom fast enough. They are causing extreme diarrhea. Do you think Im lactose intolerant??

I don't think 4-5 sips of a drink are enough to cause that, but that's just my guess. It hasn't had the time to move through your digestive system, if that makes any sense. Perhaps your body is taking it as a signal that you're finally eating more so that it better make some room? I'm not really a digestive system expert, though.

sounds like a good answer though!

You would feel symptoms of lactose intolerance anywhere from 30 minutes to 2 hours after eating or drinking dairy. This sounds like something else. Would definitely recommend you have it checked out by a gastroenterologist before you consider surgery.

surgery already complete....three weeks postop

Ah. Sorry - did not see that in your profile. Try using almond milk (unsweetened and unflavored) instead of regular milk in your shake. Lots of people find themselves lactose intolerant after surgery. If that does not help, you might need to use a different protein shake, such as egg- based instead of whey. Everyone has such individual reactions to surgery. Still good to bring up with your surgeon.

Thanks...I tried egg this morning..two bites and got that sick feeling...Im going to talk to NUT today.....
