Hello, I'm one week out from my gastric sleeve. I feel great, have had zero complications. I just finished the mandatory in-home nurse check up appointment. I had asked her if it was okay that I drink more than 4oz at a time because I have no pain or problems doing so, and my meal plan only calls for 4oz of protein shake 5x a day right now.

Today was the first day I could have anything other than clear fluids, so I did drink 8oz of protein shake this morning, over about 20-30 minutes without issues.

She said I'd stretch my sleeve out if I didnt follow the 4oz rule. I didn't question her, just said Okay well I wont do that again..

But I am wondering... is it really possible to stretch my sleeve out already from just fluids like protein shakes?

It is possible to stretch your sleeve, but that is usually once it has healed and about years out. However, some people are able to drink or eat more than others due to the size of their sleeve. Not everyone's sleeve is the same size.

One week out, I could only drink water at 2oz a time. However, now I can drink about 6oz a time without a problem. However, food is different.

I would suggest following your nurse's orders as you are still fresh out of surgery. Do not push yourself because the worst thing that can happen is damage to your staple line.
