Post op question here: I am sampling some of the Meal Replacement shakes that my doctor provided for after surgery, but they produce a lot of bubbles and foam when I mix them in a shaker cup. i know we're advised against carbonated drinks, but are these bubbles and foam okay for after surgery? It's enough to produce burping for me.

Should I shake it and let it sit in the refrigerator until the bubbles dissipate before consuming?

the bubbles in carbonated drinks have a pressure to them that can do things to your stomach. (hence burping if you drink them too fast) the bubbles you are seeing in the shakes are non pressurized air trapped so should be fine!

Can’t see an issue. Those bubbles & foam are different to carbonated bubbles & will dissipate way more quickly than you’ll be able to drink your shake anyway. You can always give it a little stir to release some of the bubbles. Just ensure you’re sipping slowly - no gulps or mouthfuls & leave a couple of minutes between each sip.

I don't think it is the same thing.

What you are talking about it caused by froth from shaking it up. Carbonation bubbles have gas in them.

I will say if you let your shake sit a few minutes, most of the bubbles and foam go away. I use an electric blender cup when I use powder because I think it mixes better. It literally doubles in the cup with foam and froth but if I let it sit for a few minutes it is pretty much gone.

Thank you all so much for the replies!! ?

Idk. I would say it’s not the same thing and not to worry but if it’s enough to produce burping I think I would let it sit just to be on the safe side. Or like arabesque suggested stir it until the bubbles dissipate.

As others have mentioned, I don’t think shaker-cup bubbles are an issue (I sure hope not too!). With soda and other carbonated beverages, it’s the release of the dissolved gas in your stomach that creates the issue.
