Treatment and Outcomes

Bloat is always an emergency.  Rapid treatment is essential.  If you suspect your dog is bloating find veterinary treatment as soon as possible.

Emergency treatment for bloat centers on untwisting and relieving pressure in the stomach, plus treating for shock.  When the stomach swells and twists there is often blood flow loss and damage to other organs including tissue death.  Therefore, even after the stomach is relieved there can still be very serious problems to manage.  Hospitalization, IV fluids and close observation are routine.  About 25% of dogs who bloat will die within seven days.  Dogs who are physically depressed when they arrive for treatment are three time more likely to die.  Dogs who are comatose are 36 times more likely to die.

Risk Factors


A surgical procedure where the stomach is tacked to the body wall (called prophylactic gastropexy) prevents the stomach from twisting.  This is commonly done for dogs who have had one episode of bloat and are  therefore at grater risk of another.
