Chronic enteropathies are complex gastrointestinal conditions whose cause is often difficult to pinpoint. They involve chronic intestinal inflammation and can lead to a range of symptoms, most commonly persistent digestive issues, sometimes weight loss, or even lethargy and changes in eating behavior. Understanding these disorders is key to ensuring the well-being of our pets.
When to Suspect Chronic Enteropathy?
The symptoms of these chronic inflammatory diseases can vary depending on the severity of the condition and its location in the digestive tract. Some of the most common symptoms include:
- Persistent diarrhea for at least 3 weeks in dogs, 10 days in cats;
- blood or mucus in the stool;
- weight loss;
- recurrent vomiting;
- loss of appetite;
- lethargy;
- abdominal pain.
These symptoms can be intermittent and vary in severity, making the search for causes sometimes challenging.
The Diagnostic Journey
Chronic enteropathy investigation involves a combination of physical examinations, laboratory tests, medical imaging, and sometimes intestinal biopsies or exclusion diets. Chronic enteropathies are considered exclusion diagnoses, meaning other causes—such as parasitic or bacterial infections, cancers, or extra-digestive diseases—must first be ruled out.
Chronic Enteropathies: Causes
The exact causes of chronic enteropathies are often not clearly defined. However, factors such as abnormal immune responses, increased intestinal barrier permeability, genetic abnormalities, and microbiota imbalances can contribute to the development of these conditions.
Chronic Enteropathies: Types and Management
Veterinary gastroenterology specialists have identified 4 types of chronic enteropathies in dogs and cats, based on treatment response:
- Food-responsive enteropathies;
- Antibiotic-responsive enteropathies*;
- Immunomodulator-responsive enteropathies – formerly known as "chronic inflammatory bowel diseases" or IBD;
- Fiber-responsive enteropathies.
Once the etiological—or causal—diagnosis is established, the management of chronic enteropathies in dogs and cats depends on the case and may involve:
- a dietary adjustment;
- medical treatment;
- nutritional supplements;
- antibiotics only if an infection is confirmed.
A long-term care plan is essential to improve your pet’s quality of life, along with your ongoing monitoring. It’s important to stay alert for signs of relapse or the emergence of new symptoms. Additionally, the treatment will likely need regular adjustments.
*A team of French veterinary specialists in internal medicine has proposed this month a new classification for chronic inflammatory enteropathies in dogs. This terminology appears set to evolve toward an emphasis on gut microbiome imbalance.
