Do shakes make you full of gas?

Hi I am new to post but have been here everyday. I am having my RNY in the morning and I feel real bad the last two days. Can the liquid shakes do this. I feel full of gas.

It did for me. I couldn't wait to be off the shakes.

Yes, if you use a blender to make them, the shakes can simply have too much air whipped into them.  Try letting the shake sit for a while before drinking or try using a blender ball container rather than a blender.
