Another one here who has found no issue with high fat after gall bladder removal.
The advice they gave me was not to switch to a low fat diet, but to go easy on the fats the first couple of days after the OP, and build it up again to see how I'd react.
I didn't listen, because I accidentally ran into a very high fat meal on the 4th day after the OP, which happened to be the first day I was hungry again so I was ravenous.
Decided to ignore the advice and just get it over with and see what would happen with a large plate of very fatty food, and nothing happened.
I guess building it up slowly makes more sense though, but just to show many people don't experience issues with fatty foods at all, hope you're one of them as well!
The advice to eat low fat after removal is because some get stomach trouble if they go too fast too soon. So it's to save you from discomfort, not because anything bad can happen (apart from feeling rubbish for a couple of hours).
Good luck and hope you'll have a swift recovery!
