Which therapy addresses esophageal hypomotility in a hypothyroid dog?

• A. Thyroid hormone supplementation
• B. Balloon dilation
• C. Esophageal stent
• D. Foreign body removal

Answer: (A)

Esophageal hypomotility in a hypothyroid dog improves when the underlying endocrine problem is corrected. Thyroid hormone supplementation restores normal metabolic function and supports esophageal smooth muscle contraction and neural control, allowing peristalsis and clearance to improve over time. This targets the root cause rather than just addressing symptoms. The other options tackle mechanical issues or foreign material, not the systemic motility deficit caused by low thyroid hormone. Balloon dilation or esophageal stents address narrowing or obstruction, and removing a foreign body is only needed if a physical object is present, not for endocrine-driven hypomotility.
