GDV

Gastric dilatation volvulus (GDV), also known as gastric dilation, twisted stomach, or gastric torsion, is a medical condition that affects dogs and rarely cats and guinea pigs, in which the stomach becomes overstretched and rotated by excessive gas content. The condition also involves compression of the diaphragm and caudal vena cavae. The word bloat is often used as a general term to mean gas distension without stomach torsion, or to refer to GDV.
