My favourite temperature for an appendectomy is 21 Celsius, dry air.

Anyone else experience that? — TiredThinker

Mine was removed in 1949. No aftereffects I know of.

Hmm. I heard of one other person that had long term changes in tastes.

I had my gall bladder removed about 20 years ago, Things tasted the same afterwards but the desire to eat certain things was gone. No idea why and it took me a couple of years to note the change.

How do you know you're being objectively correct in attributing the change in taste to your appendectomy?

It's not a matter of negative symptoms from eating fatty foods but purely down to taste?

Edit: They say there is a connection between taste and your microbiome and so it stands to reason if you were given a broad spectrum antibiotic for your surgery, maybe your change in taste is a result of a change in your GI flora. But that was 15 years ago, so what has sustained your opinion that you dislike fatty foods?

I think my digestive system physically can't comfortably handle fatty meats like it could before. The taste in my mouth is the same, but causes a nausea instead of affinity towards those flavors.
