Overview of Gastric Dilatation Volvulus (GDV or Bloat) in Dogs

Gastric dilatation volvulus (GDV), often referred to as “bloat”, “twisted stomach” or “gastric torsion,” is a serious condition caused by abnormal dilation and twisting of the stomach. The condition is initiated by an abnormal buildup of swallowed air, fluid, food, or foam in the stomach. Bloat can occur with or without “volvulus”(twisting), occurring between the esophagus and the upper intestine.

Prognosis for Dogs with Gastric Dilatation Volvulus (GDV)

The first four days postoperatively is the most critical time frame for dogs suffering from GDV. The mortality rate is approximately 15% for dogs treated surgically. The mortality rate is more than 30% for dogs treated surgically for which gastric resection is required. With surgery, recurrence rates are less than 10%.
