Equine grass sickness, or equine dysautonomia causes a paralysis of the gastro-intestinal tract, by disruption of the autonomic nervous system.  This leads to a pooling of ingesta throughout all parts of the gastro-intestinal tract.  The condition may occur acutely, or progress chronically over several weeks, but all cases will eventually die.  A definitive diagnosis is obtained by taking an ileal biopsy, and inspecting the intrinsic myenteric plexus.  There is no effective treatment, although in the short to medium term, horses can be successfully managed by informed and attentive owners.
