I've heard two things:

1) It fills up your stomach and you need the room for nutrition.

2) It washes the food through, making you eat more.

Okay, which is it??

I heard #2

It's actually both. Sometimes I just can't stand it though. I get so thirsty, I have to have a sip of water when I eat.

Also, at least in the early days:

#3. It hurts.

Why does it hurt? Because your stomach gets too full?

My husband's information book from his surgeon says that it pushes the food through too fast and that it could possibly stretch the sleeve. So it's probably a combination of all these things.

Yes, it hurts because there isn't room. It hurts the same way that eating too much food hurts.

It doesn't really "push through" the food. That's a RnY thing because they have no pylorus valve. However, the pylorus valve is designed to open up when liquid and mush hits it. Adding Water to your food turns it to mush faster so the pylorus valve opens up faster.

This was true pre-op as well. My son, who is underweight, constantly gives his dad a hard time about drinking with dinner. He says the only reason to do that is to fit in more food. Smart boy. :001_smile:
