The first documentation of gout was in Egypt, in a description of an arthritic big toe with unique symptoms, around 2,600 BC.
Hippocrates knew of gout, and noted its absence in eunuchs and pre-menopausal women.
The realization that the urate crystals found in the urine and joints of gouty patients (first noted by Leeuwenhoek in 1679) was directly related to the symptoms caused wasn’t reached until Alfred Baring Garrod proposed the mechanism of pain in 1848.
Humans and other great apes lost the ability to produce uricase, which is part of the reason that we develop gout, and most other animals don’t…though if the ability to produce that enzyme is interfered with, gout CAN occur. Sue the Tyrannosaurus rex is thought to have been gouty, after all. It’s not known if some larger reptiles did not have the ability to produce uricase in general, or if Sue simply had a genetic defect.
