Bilious Vomiting Syndrome

Bilious Vomiting Syndrome (BVS) is a condition observed in dogs, characterized by the vomiting of bile, typically occurring in the early morning or late at night. This syndrome is often seen in otherwise healthy dogs and is believed to be caused by an accumulation of bile in the stomach, leading to irritation and subsequent vomiting.

Pathophysiology[edit]

Bile is a digestive fluid produced by the liver and stored in the gallbladder. It is released into the small intestine to aid in the digestion of fats. In some dogs, bile can reflux into the stomach, especially when the stomach is empty for prolonged periods. This can irritate the gastric mucosa, leading to vomiting. The vomitus is typically yellow or greenish in color due to the presence of bile.

Clinical Presentation[edit]

Dogs with Bilious Vomiting Syndrome often present with:

Vomiting of yellow or greenish fluid, usually occurring in the early morning or late at night.
Otherwise normal appetite and behavior.
No significant weight loss or other systemic signs of illness.

Diagnosis[edit]

Diagnosis of BVS is primarily based on clinical history and ruling out other causes of vomiting. A thorough physical examination and diagnostic tests such as blood work, abdominal ultrasound, and endoscopy may be performed to exclude other gastrointestinal disorders.

Management[edit]

Management of Bilious Vomiting Syndrome typically involves dietary modifications and medical therapy:

Dietary Changes: Feeding small, frequent meals throughout the day and providing a late-night snack can help prevent the stomach from being empty for long periods, reducing bile accumulation.
Medical Therapy: Medications such as proton pump inhibitors (e.g., omeprazole) or H2 receptor antagonists (e.g., famotidine) may be prescribed to reduce gastric acidity and protect the gastric mucosa.

Prognosis[edit]

The prognosis for dogs with Bilious Vomiting Syndrome is generally good, especially with appropriate dietary management and medical treatment. Most dogs respond well to treatment and can lead normal, healthy lives.

-The exact cause of bilious vomiting syndrome is unknown. However, it is believed to be due to a buildup of bile in the stomach overnight, which irritates the stomach lining and leads to vomiting. This is more common in dogs that are fed once a day, as the stomach is left empty for a longer period of time.
