I have basically been hungry since day 2 after surgery. I am 9 days post op and have started getting shaky and light headed, kind of a hypoglycemic feeling. I am getting in my protein and water and have set a timer to remind me to eat every 3 hours. I handle liquids, yogurt and some mushy foods with no issues. I will stop when I feel at little pain at the bottom of my stomach. That might be my "full" but I can't say for certain. Since I am unsure about being full I am portioning out 1/4 to 1/2 cup per meal (depending on consistency).

This might sound stupid but I'm not sure what my body is telling me I need. I know when I would feel like this pre-sleeve I would eat everything I could to make the feeling go away and was rarely successful.

Any suggestions are greatly appreciated.

If you can get a blood glucose meter that would be good. When you feel that way, you could test your sugar to see if it is the culprit.

But, because you have a history of feeling that way, and eating didn't remedy it, it doesn't sound like hypoglycemia.

You might have a sensitivity to something you are consuming. Dairy (including whey in the shakes) and artificial sweeteners are common problem-causers.

That feeling of hunger is usually acid. Make sure to take your acid meds religiously.

And, of course, feel free to mention this stuff to your surgeon.

Thank you for the feedback.
I bought some Fairlife milk today and a sample of a non-whey protein.
I made the shake this afternoon and was surprised that I could only drink 2-3 oz comfortably over 20 minutes.
I was able to drink the whey protein shakes much faster.
I currently take a Prilosec every morning. Is there something else I can take in addition for acid?
I'm slowly moving on to soft foods starting tomorrow so I hope to be able to consume much less artificial sweeteners. I hated them pre-op and still hate them now.

The prilosec should be good, but you could ask your surgeon if you could try a liquid antacid for when you feel hungry (immediate relief). If you still feel hungry after taking the liquid, then maybe it is actual hunger (or just the healing of your tummy).
