K23.1: Megaoesophagus in Chagas disease

The esophagus or gullet connects the mouth with the stomach. It is a muscular tube. The muscles in the esophagus move food into the stomach. The muscles of the gullet are controlled by nerves. The nerves influence how strongly the gullet contracts or relaxes.

You have been infected with a specific pathogen. This pathogen has caused the nerves in your gullet to be damaged. Because the nerves are no longer working properly, the muscles in the gullet are also no longer functioning. Your gullet has thus become severely dilated.
