Inflammatory bowel disease – what's behind this long name?

This chronic inflammatory bowel disease occurs in dogs and cats, with a genetic predisposition suspected in certain dog breeds (boxers, German shepherds). IBD is triggered by an excessive reaction of the immune system, can affect both the small and large intestines, and is incurable.

Causes and development

Although a genetic predisposition to certain breeds is suspected, no actual genetic defect that promotes the disease has yet been identified. The exact causes of IBD therefore remain unknown. It is likely that it is an autoimmune reaction of the intestinal mucosa triggered by various factors.

The small and large intestines are usually affected; in rare cases, the inflammation is limited to one section of the intestine. The recurring inflammation in the intestine leads to an excessive accumulation of inflammatory cells and immune cells in the intestinal mucosa. The intestinal wall thickens and significantly restricts the intestine's mobility and nutrient absorption.

Symptoms

The consequences of reduced intestinal function are chronic, recurrent, watery diarrhea, severe flatulence, and vomiting. If the small intestine is also affected, severe weight loss often occurs, as the absorption of nutrients and energy in this section of the intestine is disrupted. The disease progresses in episodes, between which the affected animal may appear healthy again. Depending on the severity of the disease, dehydration, anemia, protein loss, and ascites may develop as the disease progresses.

Diagnosis

Since the symptoms are quite unspecific, at least at the onset of the disease, it is essential that the treating veterinarian receives a very detailed preliminary report. This is the only way to make accurate statements about the severity and duration of the disease. All other causes of diarrhea must now be ruled out in order to indirectly arrive at a diagnosis of IBD. These can include parasites, pancreatic diseases, tumors, or food allergies.

Depending on the preliminary report and findings, the veterinarian will perform further blood tests, ultrasound, and X-ray examinations. However, this suspicion can only be confirmed with certainty by a colonoscopy and subsequent microscopic examination of a tissue sample from the intestinal mucosa.

Treatment

Due to a lack of knowledge about the exact causes of IBD, there is still no cure for the disease. Treatment of IBD is therefore aimed exclusively at alleviating the symptoms. As a pet owner, it is important to know that your pet will require lifelong treatment. Anti-inflammatory drugs are used, and in severe cases, preparations that suppress the immune system's overreaction. Your vet will draw up a detailed treatment plan for your individual case and can send you the medications for your dog digitally via petsXL, so that you can find all upcoming medication doses in your timeline and set reminders for yourself.

Special foods must also be fed to avoid putting unnecessary strain on the dog's hypersensitive gastrointestinal tract.

Forecast

Regular check-ups and a treatment and nutrition plan tailored precisely by your veterinarian require a lot of patience, time, and consistency on your part, but they allow affected animals to live a largely normal life. However, relapses, known as acute episodes of the disease, must always be expected.
