The most common cause of Bilious vomiting syndrome in dogs

Bilious vomiting syndrome in dogs is a fairly common phenomenon .

This is a reaction to an overproduction of bile in the digestive system that causes this type of vomiting.

Dogs with bilious vomit syndrome vomit on an empty stomach several hours after eating .

Often this symptom is neglected, but I advise you to fix it as soon as possible to avoid your dog’s other health concerns (ulcer,chronic gastritis,…).
Bilious vomiting syndrome is a form of gastritis

Gastritis is characterized by the fact that the lining of the stomach is inflamed.

In the case of bilious vomiting syndrome, this inflammation is produced by the bile which is naturally secreted. The mucous membrane of the stomach becomes more fragile and the level of acidity increases.Bile and acids thus increase irritation and inflammation of the stomach and when they reach a certain degree, the reacting dog vomits.
Symptoms of bilious vomiting syndrome

Dogs with bilious vomiting syndrome will tend to vomit in the morning, on an empty stomach, several hours after eating their last meal.When the stomach is empty, the acids cause irritation.

The symptoms of this condition are::

Vomiting in the morning or late evening
Vomiting yellow (bile)
Previous signs of distress or pain vomiting

Treatment of bilious vomiting syndrome

1) the first tip is to reduce the waiting time between meals .As it is the empty stomach that is responsible for this syndrome and well multiply the number of meals in the day( small quantities) and especially give him one last small meal before going to sleep.

2) at the level of medicinal products :

there are some medications that can help treat this syndrome.
To decrease the acidity of the stomach, :

1)Antihistamines H2

H2 means histamine receptors: in fact these drugs prevent the activation of these receptors and thus fight against the acidity of the stomach .

as a molecule :

Cimetidine (Tagamet*): 5-10 mg / kg, 3x / day
ranitidine (AZantac*, Raniplex*): 0.5-2mg / kg twice daily

2) proton pump inhibitors

Also, it is a family of medicines that reduces the acidity in the stomach and is even more effective than antihistamines .

They work by inactivating the “pumps” that produce hydrochloric acid.

as a molecule : omeprazole (Mopral*):0.7 mg / kg taken alone in the evening .

here you need a prescription !!

3) antacids

These are products that neutralize the acid in the stomach, which relieves the pain!!

Maalox*: 0.5 to 1 mg / kg 2-4 times daily
Gaviscon*: 25 mg/kg 2-4 times a day
Phosphalugel* or phoshaluvet: 145 mg / kg orally 3-4 times per day

4) anti-emetic( against vomiting)

metoclopramide (Primperan * Primperid*): 0.2-0.5 mg/kg orally

So in a nutshell :

1) split the meals during the day and give one last small meal before going to sleep to your dog .

2) if repeated bilious vomiting diet for 12 hours, only water per small amount
give her Tagamet * + an antacid (Phospaluvet*) to relieve the pain .
Eventually, give PRIMPERAN one day to flush the stomach

If no improvement or blood in the vomit, consult your veterinarian for an examination of the digestive system ( ulcers ,….)

When a dog vomits bile, it usually does so after a prolonged period of fasting. If your pet has spent hours on an empty stomach, bile, along with other digestive fluids, accumulates in the stomach without the presence of food.

These fluids are prepared to facilitate digestion of food, but without the presence of these in the stomach, they are very aggressive to the gastric mucosa.

Bile irritates and inflames the gastric mucosa, therefore, as a defense response of the digestive tract, vomiting occurs. In this context, vomiting occurs only in the form of a yellow and greenish liquid.
