So, for the last 3 weeks, I have been plowing through all of the pre-op checklist and appointments. I have completed the "required" items and the patient advocate has told me that we are waiting for the approval for VSG. One of the "needed" items from the doc was/is an abdominal ultrasound.

I'd told the doc that I had been in the hospital a few summers ago and all sorts of tests were run and that I am pretty sure that the ultrasound was done already. The advocate called me today and said that I need another scan done as there was inflammation on my gallbladder during the test from when I was hospitalized. I was hospitalized for an intestinal issue and no one ever mentioned that there was any inflammation. I have done some research today and I understand the relationship of gallbladder/stones and weight loss, but I am wondering if it's possible that I have been living with some sort of gallbladder issue and not realized it.

I will admit that from time to time I have had some intermittent pain in the right upper area just below the ribcage, but always just thought that it was normal based on my eating habits and size.

so my questions are this: Is it possible that I have had some sort of gallbladder/stone issue for a couple of years without having had a "major" attack?

And is it common (or encouraged_) to have the GB removed during the VSG? Also, is there any chance that this GB issue is going to delay my surgery?

Definitely possible to not know you have an issue. I had no symptoms for years. Lab tests tipped off that I had stones, ultrasound confirmed it. i knew about them for about 3 years until I became symptomatic. And trust anyone who has had a full blown attack, you don't want to keep the gall bladder. My doctor was going to remove my gall bladder when I got sleeved, so if it needs to come out, ask if they can come out together. Good luck! Much better to know now that its an issue than after.
