Enteropathic arthropathy or enteropathic arthritis refers to acute or subacute arthritis in association with, or as a reaction to, an enteric (usually colonic) inflammatory condition.
Causes and associations
Note that reactive arthritis can also occur secondary to urethral infection. In that case, the term enteropathic arthropathy would not be used.
