Achalasia

Overview

Achalasia results from damage to nerves in the food tube (esophagus), preventing the esophagus from squeezing food into the stomach. It may be caused by an abnormal immune system response.

Symptoms

Symptoms include a backflow of food in the throat (regurgitation), chest pain, and cough. Weight loss is common.

Treatments

Achalasia can usually be managed with minimally invasive (endoscopic) therapy or surgery.
