Megaesophagus

descriptionOverview

Megaesophagus is a condition where the esophagus loses its ability to push food into the stomach, causing it to stretch and become a floppy tube. Food accumulates in the esophagus and is regurgitated (not vomited — it comes back undigested). The biggest danger is aspiration pneumonia from food entering the lungs. It can be congenital or develop later in life.

searchSymptoms to Watch For

• warningRegurgitation of undigested food (passive, unlike vomiting)
• warningWeight loss despite good appetite
• warningBad breath from food sitting in esophagus
• warningCoughing or nasal discharge after eating
• warningVisible distension of the neck area

restaurantHow Nutrition Helps

Dogs with megaesophagus must eat in an upright position (Bailey chair) and remain upright for 20-30 minutes after eating. Small, frequent meals of a specific consistency (liquid slurry, meatballs, or elevated kibble) work best — the ideal consistency varies by dog. High-calorie, nutrient-dense food ensures adequate nutrition despite small portions.
