Ana Eats

Remember too you’re only eating very small portions at this stage. If you keep to your portion size recommendations you likely won’t feel your restriction unless something is sitting more heavily in your tummy, you’re drinking while you eat or eating to quickly. (I was advised 1/4 - 1/3 cup from purées gradually increasing to about a cup by 6 months but check with your team for what they suggest for you & your needs.)
Many of us find our signals are different now too & it can take time to work out what they are for you. The goal should not be to eat until you feel full. It takes 20+ minutes for that message to get through to our brains. (One of the reasons we’re told to eat slowly.) So by the time you feel full you likely have eaten way past full. Try to work out your ‘I’ve had enough’ signals. I ask myself do I need another bite or just want it. If I just want it I stop.
Oh & it would take a concentrated effort of eating large quantities of food over a long period of time to stretch your tummy.

When we have surgery a lot of nerves are cut that take months to regenerate. The ones that send the message that you are "full" haven't healed yet, that's why you aren't getting the signals. Odds are in two to three months you will notice your signals for fullness are different from what they are now. "Just because you can, doesn't mean you should." definitely applies here. Don't worry, your restriction is there, you just can't feel it. And fluids are way different than restriction from solids...

You may have been lucky this time but I wouldn’t push it. There are a lot of sutures & staples holding your tummy together & the staged return to eating is in place to protect your wounds & support your healing & recovery.
Generally we’re told to avoid Pasta - not just during the staged eating phase. It, like rice & bread, are more highly processed, nutrient poor food that will swell & feel heavy in your tummy. It fills your much smaller tummy restricting you from eating the nutrient dense foods you need to be eating like your Protein. In a while you may be able to add carbs back into your diet, but then the rule usually is eat your protein first, then any vegetables & finally if you’re able any carbs you are allowed.

OP - 1) the above commenter is correct about nerves not being healed yet. 2). liquids go right through you, so you're not going to feel full on those, healed or not. You'll start feeling some restriction once you move to solid foods.

I have the same thing, and I'm 5.5 weeks post-op. I've never yet felt that "Stop! You're full now!" warning. And like you, it does worry me. I hadn't heard about the nerves being cut and that's why I'm not receiving the signals. Very interesting. And it makes sense. I just wish they'd hurry up and heal because I really don't want to stretch my stomach.

I'm currently on the liquid part of the pre-op diet. I haven't had any accidents. In fact, if anything, I'm a little on the constipated side... I have to pee more but that's normal with more Fluid intake and as long as I listen to those messages in enough time I don't have to run to the bathroom! LOL
Catwoman7 is right, if you can drink blends you can get those at Amazon, Target, or even costco. Pre-surgery I'm supposed to drink the Premier Protein ready to drink ones, but after surgery it is only whey Protein isolate so I bought some sample packs here on BariatricPal, as well as some from Unjury, and a bag of unflavored GENEPRO since I can put that in anything. Make use of the sample sizes!! That will save you a lot of money in the end!

My post-surgery pain has been quite minimal. A little pain on my right side, especially when I need to use those abs. And the rear roof of my mouth feels really badly bruised from the intubation I guess -- I've never had that before after surgery so it is not likely to be related to WLS, just my particular experience this tie. I'm basically able to do most of what I did before, but already with less pain. 3 days out, 5 pounds down from surgery weight.
