What's "GI"?

Please don't use acronyms that people might not understand.




GI is a pretty common acronym for 'gastro intestinal'

'The GI Doc', 'I have GI issues', etc


First time I've seen it. If it weren't for this discussion, my first thought on a GI Doc might be that it's a doctor in a military zone or is otherwise related to the military.

The first 5 results on

https://www.urbandictionary.com/define.php?term=gi

say that it's either "Government Issue" or "General Infantry". Gastrointestinal isn't even among the results.

Google's first few results are likewise about the military.

Keep in mind that HN is a global community.



It took me some time to figure it out, but I think it's "gastrointestinal".


Gastro-intestinal.


General Infantry.
