MEGA-ESOPHAGUS.

This refers to a condition where peristalsis is altered because of an enlarged esophagus.The esophagus is the passage of food from mouth to stomach,thus when its enlarged the food passage is stalled leaving food in the throat for a prolonged time,the food is usually regurgitated or inhaled in lungs resulting in aspiration pneumonia The food often times decays in the throat resulting in foci of infection. The condition is common in horses,cats,dogs and humans,and it could be inherited as in the Friesian horse. The common signs associated with mega-esophagus are 1) inappetence 2) frequent episodes of regurgitation 3) severe weight loss. There are certain breeds predisposed to mega-esophagus, these include 1) great Dane,2) German shepherd 3)golden retriever 4)corgis,5) Siamese cat 6)Persian cat 7)Boston terrier 8)rottweiler 9)french bulldog e.t.c. The prognosis of the condition is guarded and the remedy is feeding the subject in a raised position; where the neck is stretched vertically to receive food and create an easy passage to the stomach. Dogs are usually fed in special chairs,to ensure they have required calories and prevent food stasis. photo credit; The telegraph.
