Gastrointestinal stasis

Gastrointestinal stasis, GI stasis, GI hypomotility or ileus is a serious condition that requires immediate attention. The condition occurs when the gut stops moving, is blocked, or is full of gas.

Symptoms

 * Loss of appetite (anorexia) or changes in eating habits. A good way to test this is to offer fresh herbs or a favorite treat.
 * Small to no stool, loose or mucous covered stool or diarrhea.
 * Sitting in a hunched position or pressing stomach against the floor.
 * Loud tooth grinding which is an indication of pain. This is different than the "tooth purr" that indicates pleasure or contentment.
 * Loud GI sounds or complete silence in the stomach. You can use a stethoscope or listen with your ear pressed against the stomach.

Causes

 * Stress
 * Pain from an underlying condition (e.g. gas, dental problems, infections, or urinary tract disorders)
 * Dehydration
 * Lack of dietary fiber
 * Intestinal blockage

Diagnosis
Gastrointestinal stasis can be usually diagnosed as non-obstructive or obstructive ileus.

Treatment
You should seek immediate veterinary assistance if your rabbit has not eaten or passed stools in the past 12 hours or is exhibiting other symptoms of GI stasis. Your vet will provide proper treatment and care. If left untreated, GI stasis can be fatal in 48 hours.

For at-home initial treatment when you first notice symptoms, you can do the following:


 * For an acute gas attack, feed 0.5cc to 1cc of infant simethicone (20 mg/mL suspension) to your rabbit every hour for the first three hours, then every three to eight hours. This product is easily obtainable in the baby sections in a drugstore, pharmacy, or supermarket. Simethicone has no known drug interactions and is not absorbed through the intestinal lining. It acts only on a mechanical principle: it changes the surface tension of the frothy gas bubbles in the gut, joining them into larger, easier-to-pass bubbles.
