Hello. Thanks for writing in. My name is***** and I would be happy to help you. Many of these chronic gastrointestinal issues in cats can be related to a dietary problem, a food allergy, a chronic pancreatitis, hyperthyroidism, inflammatory bowel disease (IBD) or intestinal lymphoma. In face, hyperthyroidism, IBD and lymphoma can show the exact same clinical signs. The only ones out of these diseases that can be diagnosed with blood work is hyperthyroidism and pancreatitis. So, make sure your vet ran a feline pancreatic lipase (FPL) and a thyroid value. Those are not normally on routine blood panels. I would probably help at this point to get an x-ray and/or an ultrasound of the abdomen. It is possible that some of these other diagnoses can be made with these tests, but endoscopy and biopsy of the intestinal tract is usually necessary for confirmation. So, from here, I would talk to your vet about running the FPL and thyroid if not already done, pursue a x-ray and/or ultrasound and consider potential endoscopy. If endoscopy and biopsy are not pursued, I will put some of these cats on a hypoallergenic diet, prednisolone and metronidazole, assuming the blood work is normal otherwise. That would more or less be a general treatment plan for some of these other issues. It won't confirm any specific diagnosis, but will help with most of these other diseases. It would probably help to get him on a few days of Cerenia for nausea as well. Please let me know if you have any other questions or concerns. Hope this helps.
