Inflammatory Bowel Disease (IBD) in pets

Published on 17 Jun 2021

The term Inflammatory Bowel Disease (IBD) refers to several inflammatory gastrointestinal diseases. They are usually chronic/recurring and idiopathic (cause unknown). Some thoughts on the possible underlying causes for IBD include factors relating to diet, environment, the immune system, and the intestinal microbiome. There may also be a hereditary component to the development of IBD. 

In IBD, abnormal immune function results in many inflammatory cells accumulating within the gastrointestinal tract. The overall effect of overactive inflammatory cells and their products leads to changes in the lining of the gastrointestinal tract. This can lead to malabsorption of nutrients through the intestinal walls, or leaking of fluids, proteins, and blood into the intestines. 

Who is affected? 

IBD can affect both cats and dogs of any age, although according to PetSure claims data, is most prevalent in dogs and cats between 1 and 5 years of age. 

According to PetSure data over the 2020 calendar year, IBD was most prevalent in the following breeds: 

Breed Prevalence
Birman Cat1.01%
Shetland Sheepdog0.96%
Australian Silky Terrier 0.77%
Exotic Short Hair Cat0.75%
Devon Rex Cat0.72%
Persian Cat 0.67%
Siamese Cat 0.60%
Tenterfield Terrier0.60%
Standard Poodle0.48%

*Prevalence = Total number of unique claiming pets / total number of insured pets across 12-month period. Excludes breeds with less than 500 active pet insurance policies.

Signs of IBD

The signs of Inflammatory Bowel Disease are those signs commonly associated with gastrointestinal disease. This includes vomiting and diarrhoea sometimes with blood, flatulence, weight loss, decreased appetite, and signs of abdominal pain. In severe cases pets may be dehydrated and in poor body condition. 

Diagnosing IBD 

To diagnose IBD, the Vet will take a thorough history including noting for how long and how frequent the gastrointestinal signs have been for as well as perform a thorough examination of the pet patient. 

Diagnostic testing often includes blood tests, stool tests, abdominal ultrasound, and biopsies of the intestines. Further testing may be required to help rule out conditions like intestinal lymphoma. It is not unusual to find other conditions, such as pancreatitis in pet patients suffering from IBD. 

Management of IBD

Treatment of IBD often involves a combination of dietary and medical management. Commonly, a food trial is a first point of call. This may mean feeding the pet patient a hypoallergenic, hydrolysed protein or novel protein diet to try to discern whether there is an intolerance to a particular food or protein source. 

During a food trial it is important that the patient is fed the prescribed diet only, without additional foods or treats. Medications that may be used in the treatment of IBD include antibiotics and immunosuppressing drugs such as steroids. 

It is also important to treat any concurrent diseases such as pancreatitis, and manage other issues that can arise from IBD, such as low vitamin B12, which is often low in pets with malabsorptive diseases. 

Some vets may also recommend probiotics.  

How much does it cost to treat IBD?

According to PetSure claims data from the 2020 calendar year, the average, single treatment cost relating to IBD was $328, with the highest, single treatment cost being $11,437. It is important to highlight that IBD often requires ongoing management. 

The overall treatment cost of managing IBD will vary depending on the treatments that have been recommended and your pets response to those treatments.
