Diarrhea from protein shakes?

I'm doing my pre-op diet right now and am on day 9 of drinking the (Unjury) protein shakes.  My surgeon's office requires us to purchase the pre-op protein shakes from them, so that's why I am specifically using the Unjry. 

I never had a reaction or intolerance of dairy/whey products in the past, but it sure does seem like I've had a lot of diarrhea since I've been using the protein shakes 3x a day.

Anyone else experience this?

Liquid in, liquid out. Just be happy for being able to go without the assistance of pills. That will be your post in a few months haha.

Liquids in. Liquids out.

Never trust a fart. Seriously.

 Ditto the past responses. Be happy you are getting it out now. That will change soon enough.

 i am experiencing it now too  ugh

It's normal.  My surgeons nurse also said it was related to the amount of protein you are taking in at one time with the shakes.

I would not totally discount the intolerance to the dairy/soy/whey. I have to use a plant based protein called PlantFusion, it is gluten free, soy free and dairy free. If the issue continues after surgery when you take in less of the protein drink, I would think about switching what type of protein drink you use. But I think we all had the same bathroom issue during the liquid phase of things. I was allowed to add Metamucil clear to mine to help. And it did help. Also helps now for the opposite problem. Fiber is good in so many ways.

I have been doing great on the myoplex during my pre-op liquid diet this week.... but last night I had the unjury chix soup (tasted amazing ) and have had the runs and cramps >.

Soy & dairy do that to me.  Sometimes it is just trial and error.  I would try a soy and dairy free protein and see if it helps.  The Pre-op diet tends to give you the runs.  It did me, just not a lot of fiber.  As you get to the solid food phase, you will probably have the opposite problem, as most of us do.  I finally figured out what a stool softener does.  :O).  I now use Colace, 3 a day, and that works for me.  Your body will go through tons of changes over the next months.  Take one day at a time, listen to your body and take notes of what works and what doesn't.  Blessings on your journey.
