Bilious vomiting syndrome

From WikiMD's Food, Medicine & Wellness Encyclopedia

Bilious vomiting syndrome is a medical condition that primarily affects dogs, particularly those of small breeds. It is characterized by vomiting on an empty stomach, often in the morning, due to an excess of bile in the stomach. The vomit is typically yellow or green in color, indicating the presence of bile.

Causes[edit | edit source]

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.

Symptoms[edit | edit source]

The main symptom of bilious vomiting syndrome is vomiting on an empty stomach, often in the morning. The vomit is typically yellow or green in color, indicating the presence of bile. Other symptoms may include loss of appetite, weight loss, and lethargy.

Diagnosis[edit | edit source]

Diagnosis of bilious vomiting syndrome is typically based on the dog's symptoms and history. Other conditions that can cause similar symptoms, such as gastrointestinal diseases, should be ruled out. This may involve blood tests, imaging studies, and possibly endoscopy.

Treatment[edit | edit source]

Treatment for bilious vomiting syndrome typically involves dietary changes. This may include feeding the dog smaller, more frequent meals, particularly before bedtime. Medications to reduce stomach acid and protect the stomach lining may also be prescribed.

Prognosis[edit | edit source]

With appropriate treatment, the prognosis for dogs with bilious vomiting syndrome is generally good. However, it is important for owners to monitor their dog's symptoms and seek veterinary care if they worsen or do not improve.
