My cat has ileus and won't eat. Could it be IBD? What tests now?

Updated On September 23rd, 2025

A 12-year old Siamese cat has pancreatitis and ileus, the pancreatitis subsides and he started eating, however the ileus persists and interrupts his appetite and lifestyle. 1. Should we treat the ileus and how? Will it stop after treatment? 2. Is ileus a common symptom of pancreatitis? 4. Should we consider other diagnostics tests besides blood/chemistry profile and fPLI? 5. How worried should we be that he may have major underlying diseases such as IBD / Lymphoma? Thank you!

I'm sorry to hear your cat is having GI issues. How was your cat diagnosed with pancreatitis? If the remainder of bloodwork was normal and the fPLI was positive, I would consider X-rays and possibly an abdominal ultrasound for more information. Pancreatitis can be a chronic condition that requires diet changes, B12 supplementation and long-term medications. Pancreatitis can be concurrent with another underlying GI issue, such as IBD or lymphoma. Ultrasound can give more information, but these conditions can only be definitively diagnosed with intestinal biopsies. As the issue isn't resolving, I would recommend your cat be re-evaluated and further diagnostics potentially fine, either by your regular veterinarian or an internal medicine specialist. Good luck!
