Gastric Dilation in Rabbits Gastric dilation is a syndrome in
which the stomach expands (dilates) due to excess gas and fluid,
resulting in complex local and systemic changes in the digestive
tract. In most cases, it occurs due to foreign body obstruction.
In rare instances, the stomach dilates in the absence of a
foreign body. In either case, a mechanical or functional
obstruction occurs at the opening of the stomach into the
intestine, and fluid or semi-digested food accumulates in the
stomach. Twisting of the stomach, a condition called gastric
volvulus, is rarely seen in concurrence with distension, but has
been reported. More commonly, the pressure due to distension
will result in a lack of blood supply and pressure on the
nerves. These changes may account for acute (sudden and severe)
clinical signs, such as severe abdominal pain, shock, and even
heart failure. Symptoms and Types Although weakness and/or
collapse are the most common historical findings associated with
gastric dilation, rabbits may also
