Chronic Emesis, Chronic Vomitus (Chronic Vomiting) in Dogs

Occurrence: common
Location of illness: Abdomen/pelvis

Chronic emesis, also known as chronic vomiting, is a condition in dogs characterized by repeated vomiting over a period of more than two weeks. It is a symptom that can indicate a variety of underlying health problems, rather than being a disease in itself.

The most important facts at a glance

Chronic vomiting in dogs is a complex reflex mechanism triggered by various stimuli. It can be caused by gastrointestinal disorders such as gastritis or enteritis, systemic diseases such as kidney failure or liver disease, as well as infections, poisoning, or medications. Dietary changes, poor quality food, or stress can also play a role. An accurate diagnosis requires a comprehensive examination by the veterinarian, including blood tests and imaging procedures. Treatment depends on the cause and may include medications, dietary changes, or fluid therapy. The prognosis depends on the cause but is often favorable with timely treatment.

For the prevention of chronic vomiting, a balanced diet is important, and sudden changes in feed should be avoided. Regular veterinary check-ups help to detect health problems early. Stress reduction is also important to minimize the risk of vomiting. Research is being conducted on better diagnostic methods as well as new therapeutic approaches, including special diets and probiotics. Genetic factors and immune-mediated processes are also being investigated to improve the understanding and management of this disease.

Causes

Vomiting in dogs is a complex reflex mechanism that can be triggered by a variety of stimuli. In the brain, there is a special center called the “vomiting center”, which responds to signals from the digestive tract, the vestibular system (balance system), the cerebral cortex, and the chemoreceptor trigger zone in the brain to trigger vomiting. The activation of this center can be triggered by physical, chemical, or sensory stimuli.

Chronic vomiting can be caused by a variety of factors. These include gastrointestinal disorders such as gastritis, enteritis, or inflammatory bowel disease. Systemic diseases such as kidney failure, liver disease, or endocrine disorders (e.g., Addison’s disease) can also lead to chronic vomiting. Infections with parasites or bacteria, poisoning, and certain medications are other possible causes.

An important factor that must also be considered is the dog’s diet. A sudden change in diet, poor quality food, or feed intolerances can also lead to chronic vomiting. In addition, stress and anxiety can increase the risk of vomiting in sensitive dogs.

Determining the exact cause of chronic vomiting can be challenging, as many conditions can cause similar symptoms. A thorough examination by a veterinarian is therefore essential to identify the underlying cause.

Symptoms

Very common symptoms:

Common symptoms:

Hematemesis (Vomiting Blood)

The main symptom of chronic emesis is repeated vomiting over a longer period of time. The dog may vomit several times a day or only occasionally. The vomit may consist of undigested food, bile, or mucus, depending on the underlying cause and the timing of the vomiting after feeding.

In addition to vomiting, other symptoms may occur, such as loss of appetite, weight loss, lethargy, and dehydration. In some cases, diarrhea may also occur, especially if there is a gastrointestinal cause. Cough or gagging may also be observed if the vomiting is associated with irritation of the throat or esophagus.

Behavioral changes such as increased restlessness or withdrawal can also occur. If the vomiting is triggered by pain or discomfort, the dog may show signs of discomfort, such as frequent lip licking, smacking, or curling up the abdomen.

Diagnosis

The diagnosis of chronic emesis begins with a detailed history and physical examination by the veterinarian. The veterinarian will ask for details about the vomiting episodes, feeding, environment, and possible stressors. A thorough clinical examination can help rule out obvious causes.

After the initial examination, various diagnostic tests may be necessary to determine the cause of the vomiting. These include blood tests to detect infections, organ dysfunction, or metabolic disorders. A fecal examination can help rule out parasitic infections.

Imaging procedures such as X-rays or ultrasound examinations of the abdomen can be used to identify structural abnormalities, tumors, or foreign bodies. In some cases, an endoscopy or biopsy of the digestive tract may be necessary to diagnose inflammatory conditions or neoplasms.

Therapy

The treatment of chronic emesis depends on the underlying cause. If a specific disease is diagnosed, the therapy aims to treat or control it. Antibiotics or antiparasitic drugs can be used for infections, while hormone preparations may be necessary for endocrine disorders such as Addison’s disease.

For symptomatic relief of vomiting, antiemetics (medications that suppress vomiting) can be prescribed. These medications help control the symptoms while the underlying cause is treated.

Dietary changes can also be part of the treatment. An easily digestible diet or hypoallergenic food can help relieve the digestive system and avoid feed intolerances. In some cases, a change in diet alone can significantly reduce or eliminate vomiting.

In cases of severe dehydration or electrolyte imbalances, fluid therapy may be necessary, either through oral rehydration solutions or, in severe cases, through intravenous fluid administration.

Prognosis and follow-up care

The prognosis for dogs with chronic emesis depends heavily on the cause of the vomiting. With timely diagnosis and appropriate treatment, the prognosis for most dogs is favorable. Many causes of chronic vomiting are treatable or at least well controlled.

However, if the vomiting is caused by a serious or advanced disease, the prognosis may be more guarded. Conditions such as tumors or severe organ dysfunction can significantly affect the quality of life and may require long-term treatment or palliative care.

Overall, close collaboration with the veterinarian is crucial to achieve the best possible prognosis. Regular follow-up and adjustment of the treatment strategy can help stabilize the dog’s health and provide a good quality of life.

Prevention

The prevention of chronic vomiting in dogs requires a holistic approach that considers both the diet and the general health of the animal. A balanced, high-quality diet that meets the specific needs of the dog is a good starting point. Sudden changes in feed should be avoided, and new feeds should be introduced gradually to minimize digestive problems.

Regular veterinary check-ups are important to detect and treat health problems early before they lead to chronic vomiting. Vaccinations and parasite prophylaxis should be kept up to date to prevent infections that can cause vomiting.

Stress reduction also plays a role in prevention. Stress can increase the risk of vomiting, so stressful situations should be minimized and a calm, safe environment should be created for the dog. For dogs prone to stress, behavioral modification techniques or relaxation-promoting products can be helpful.

In cases where certain medications trigger vomiting, the veterinarian should be consulted to discuss possible alternatives or dose adjustments.

Outlook on current research

Chronic vomiting in dogs is a complex medical problem that can be triggered by various underlying causes. Research in this area focuses primarily on developing better diagnostic methods to identify the causes of chronic vomiting more accurately. Advanced imaging techniques such as endoscopy and magnetic resonance imaging (MRI) are currently used to gain detailed insights into the condition of the gastrointestinal tract of dogs.

Another focus of current research is the development of new therapeutic approaches. Scientists are investigating the role of nutrition in the treatment of chronic vomiting and exploring how special diets can help alleviate the symptoms. There are also promising studies on the use of probiotics and prebiotics to improve the balance of the intestinal flora and thus reduce vomiting.

Genetics also plays an important role in research on chronic vomiting. Studies are being conducted to determine whether certain dog breeds are more susceptible to this disease and whether genetic markers can be identified to detect at-risk animals early. This research could lead to targeted breeding strategies to reduce the risk of chronic vomiting in certain breeds.

In addition, some studies are dedicated to examining the immune system of dogs and its role in chronic vomiting. It is suspected that immune-mediated processes may play a role, especially in dogs with allergic reactions or autoimmune diseases. This research could provide new insights into the treatment of immune-mediated causes of vomiting.

Overall, current research aims to gain a better understanding of the complex causes of chronic vomiting and to improve treatment options for affected dogs. These advances could ultimately lead to a better quality of life for dogs and better management of this challenging condition.
