What are the symptoms of gastric obstruction in a dog? - in detail
Gastric obstruction, also known as gastric outflow obstruction or pyloric stenosis, is a serious condition in dogs that requires immediate veterinary attention. The symptoms of gastric obstruction can vary depending on the severity and duration of the blockage, but they typically include a combination of the following:
-
Vomiting: This is often the most noticeable symptom. Dogs with gastric obstruction may vomit repeatedly, sometimes bringing up undigested food or foamy liquid. The vomit may contain blood if the obstruction has caused damage to the stomach lining.
-
Abdominal Distension: Due to the buildup of gas and fluid in the stomach, the abdomen may appear distended or swollen. This is often most noticeable when viewed from the side.
-
Loss of Appetite (Anorexia): Despite their hunger, dogs with gastric obstruction often refuse to eat due to discomfort and nausea. They may also show a lack of interest in treats or favorite foods.
-
Dehydration: Prolonged vomiting can lead to dehydration, which is characterized by dry gums, decreased skin turgor (the ability of the skin to return to its normal state after being pinched), and lethargy.
-
Salivation or Drooling: Excessive salivation can occur as a result of nausea caused by the obstruction. This may be accompanied by lip smacking, licking of the lips, or swallowing repeatedly.
-
Abdominal Pain (Abdominal Distress): While dogs cannot verbally communicate their pain, they may show signs of discomfort such as restlessness, whining, or attempting to hide or escape. Some dogs may also exhibit a hunched posture with their hindquarters raised.
-
Weakness and Lethargy: Due to dehydration, electrolyte imbalances, and the body's response to the obstruction, affected dogs may appear weak, lethargic, or unusually tired.
-
Changes in Bowel Habits: While less common, some dogs with gastric obstruction may experience diarrhea or constipation.
If you notice any of these symptoms in your dog, it is crucial to seek veterinary care immediately. Gastric obstruction is a medical emergency that requires prompt diagnosis and treatment to prevent serious complications such as shock, electrolyte imbalances, and even death. Early intervention can significantly improve the chances of a successful outcome.
