Almost 7 weeks post bypass. I have been able to eat and drink without much issue. Last night I had about 2 ounces of salmon. Felt ok but full, drank some water about an hour later and it felt full compared to my normal to the point that I skipped my Chewable vitamin. But not painful.

Then this morning I had some water, later went to have a shake and it’s uncomfortable. I tried about 4 oz over 30 min and switched to water.

Then I got 12 ounces of the water in about an hour without issue.

I went back to the shake and it was really painful with one sip. I even got a little nauseous. So water only the rest of the day. It feels kind of tight. I later tried a few ounces of the shake and it seemed ok.

So now I tried a quarter of a piece of cheese (had it before without issue). Now I have an ache in the middle of my back like I did earlier today.

I don’t have any sign of a leak no fever high heat rate etc.

Could trying salmon make me feel ok initially but 12 hours later feel bad.

Today when I drink I do burp some occasionally.

I have no idea what’s going on and I’m worried something is wrong.
Any ideas??

I know , not very helpful but call your surgeon if your symptoms continue .

I agree - call your surgeon. It could be something simple, like progressing too fast in your diet, or it could be the beginning of a stricture. Just monitor it and also let your surgeon know what's going on.

Do you have your gall bladder? Could be stones? Just a thought.
