Signalment
Description
There are many disease associations including:
| Disease Type | E.g. |
| Hypotension | Shock, Sepsis |
| Drug - induced | Non-steroidal anti-inflammatory drugs (NSAIDs) |
| Idiopathic | Stress, exercise induced |
| Inflammatory | Gastritis |
| Neoplastic | Adenocarcinoma, lymphosarcoma, leiomyoma |
| Metabolic/endocrine | Hypoadrenocorticism, liver disease, uraemia, disseminated intravascular coagulation, mastocytosis and hypergastrinaemia |
Gastric ulceration is caused by damage to the gastric mucosa through the above mechanisms. NSAIDs directly damage the mucosa and interfere with the prostaglandin synthesis. Gastric ulceration is worsened by the use of NSAIDs in combination with corticosteroids. This risk can be minimised by using cyclooxygenase-1 (COX-1) sparing NSAIDs (carprofen, meloxicam and deracoxib.
Gastric acid hypersecretion following mast cell degranulation of histamine and gastrin secretion from gastrinomas is a major cause of gastric ulceration. Sled dogs and equine race horses are prone to gastric ulceration.
