In a stable adult pet with chronic diarrhea and inconclusive initial tests, what is a reasonable approach?

• A. Consider empiric therapy after excluding serious disease.
• B. Immediately schedule invasive surgery.
• C. Ignore symptoms and observe for months.
• D. Only use antibiotics regardless of presentation.

Answer: (A)

When a stable adult pet presents with chronic diarrhea and initial tests are inconclusive, the sensible next step is to rule out serious disease and then use a diagnostic-therapeutic (empiric) trial. If there are no red flags like weight loss, blood in stool, dehydration, or systemic illness, trying a therapeutic approach helps identify whether the diarrhea is diet-responsive or potentially responsive to a limited course of therapy, without jumping to invasive procedures. For example, a diet change to a hydrolyzed or novel protein diet can quickly reveal if elimination of dietary triggers resolves symptoms; alternatively, a short empiric course of appropriate medication may be tried under veterinary guidance. Monitor the response closely: improvement supports continuing the chosen plan, while lack of response should prompt further diagnostics such as endoscopy with biopsies or imaging and a reevaluation of the treatment strategy. The other options are not appropriate in this scenario: invasive surgery is unnecessary in a stable patient, ignoring symptoms risks progression, and using antibiotics indiscriminately without regard to response or underlying cause can be ineffective and promote resistance.
