Is Vomiting Bile in the Morning an Emergency?

Persistent, projectile or bloody vomiting is an emergency. Unproductive retching is an emergency. If a dog vomits bile in the morning every now and then, it is not an emergency.

However, it’s not something I’d ignore if it happened to my dog more often than once in a blue moon.

Is Vomiting Bile in the Morning an Emergency?

What is bile?

Bile is a fluid which is secreted by the liver and stored in the gallbladder. When a dog eats, bile is released into the first part of the small intestine to aid digestion and removal of waste materials from the body.

A dog will vomit bile when it makes its way into the stomach, causing irritation and vomiting. There are theories why this happens but the exact reason(s) have not been determined.

Empty stomach?

A popular theory is that it happens when a dog’s stomach remains empty for a prolonged period of time.

Which would make sense as bilious vomiting commonly happens in dogs fed only once a day and a popular remedy is feeding more frequent, smaller meals, and/or giving a snack before bed.

On the other hand, in nature, canines often go for prolonged periods of time without eating and their systems should have developed to handle such things.

Is that a thing?

Here is what in my opinion doesn’t add up:

  1. bile is released into the intestine after ingestion of food
  2. bile accumulates when the stomach is empty

See the problem there? If it is food that triggers the release of bile, why would an empty stomach foster excess accumulation? Logically, those two statements don’t work together.

Inflammatory conditions

Diseases involving inflammation of the intestine and changes in gastrointestinal motility can be at the root of this problem.

Now, that makes much more sense. Something other than the absence of food in the stomach must be triggering this. Intestinal reflux perhaps? Except the GI tract is designed to keep moving food and fluids forward, not backward. When things are moving in the opposite of intended direction, something is causing it. And that something is what, ideally, should be identified and addressed.

With her IBD, Jasmine would get stomach upsets during which she sometimes would vomit bile. Her intestine was, however, chronically inflamed, and her motility was slow. The better we managed her IBD, the less frequent her stomach issues.

Bedtime snacks

More frequent meals and/or bedtime snacks usually help. However …

Is it solving the issue? While getting rid of the morning vomiting seems satisfactory, what about the problem that might be brewing under the surface? Such as perhaps IBD or other inflammatory processes in the GI tract?

Morning bilious vomiting is not an emergency but it warrants investigation.

I am a graphic designer, dog health advocate, writer, and author. Jasmine, the Rottweiler of my life, was the largest female from her litter. We thought we were getting a healthy dog. Getting a puppy from a backyard breeder was our first mistake. Countless veterinary visits without a diagnosis or useful treatment later, I realized that I had to take Jasmine's health care in my own hands. I learned the hard way that merely seeing a vet is not always enough. There is more to finding a good vet than finding the closest clinic down the street. And, sadly, there is more to advocating for your dog's health than visiting a veterinarian. It should be enough, but it often is not. With Jasmine, it took five years to get a diagnosis. Unfortunately, other problems had snowballed for that in the meantime. Jasmine's health challenges became a crash course in understanding dog health issues and how to go about getting a proper diagnosis and treatment. I had to learn, and I had to learn fast. Helping others through my challenges and experience has become my mission and Jasmine's legacy. I now try to help people how to recognize and understand signs of illness in their dogs, how to work with their veterinarian, and when to seek a second opinion. My goal is to save others the steep curve of having to learn things the hard way as I did. That is the mission behind my blog and behind my writing. That is why I wrote Symptoms to Watch for in Your Dog, which has turned out being an award-winning guide to dog owners. What I'm trying to share encompasses 20 years of experience.
