Which of the following is NOT listed as a non-GI disease commonly causing GI signs?

• A. Addison's disease
• B. CKD
• C. Hyperthyroidism (cats)
• D. Gastric ulcers

Answer: (D)

The main idea is that GI signs can arise from diseases outside the gastrointestinal tract, so systemic or non-GI conditions are important to consider when a patient shows vomiting, diarrhea, or weight loss. Addison’s disease can cause GI signs due to hormonal and electrolyte disturbances, making it a non-GI disease that presents with GI symptoms. Chronic kidney disease often leads to uremic gastroenteropathy, producing nausea and vomiting, so it also fits as a non-GI disease causing GI signs. Hyperthyroidism in cats can drive weight loss, increased appetite, and GI upset including vomiting, again a non-GI condition presenting with GI symptoms. Gastric ulcers, however, are a primary GI disease of the stomach itself; they cause GI signs but are not a non-GI illness. Therefore, gastric ulcers are not listed among non-GI diseases that commonly cause GI signs.
