Chronic chagasic megaesophagus may manifest as the following:

  • Weight loss and, in severe cases, cachexia
  • Hypertrophy of the salivary glands
  • Pneumonitis related to regurgitation and aspiration of the food retained in the esophagus or stomach (particularly during sleep)
  • Erosive esophagitis, with increased risk for esophageal cancer
