Depends on the size of the hernia and how lucky the horse is. If it's a very small one, then a horse can theoretically
live a very full and productive life without ever getting it fixed. If it's larger, that's when you run into the risk of a part of the intestine getting trapped in there and turning gangrenous.
I'm sure that there are some horses out there with larger ones that have full lives, but IMHO, it's not something I'd risk.
