What is esophageal hiatus dysfunction?

Esophageal hiatus dysfunction may be caused by weakened esophageal mucosal barrier, esophageal hiatus hernia, weakened esophageal motility, etc. Details are as follows:

1. Weakened esophageal mucosal barrier.

Long-term consumption of hot and cold food may cause damage to esophageal mucosa, thus causing weakened esophageal mucosal barrier.

2. Esophageal hiatus hernia.

Abdominal organs and tissues other than esophagus enter the mediastinum through the enlarged esophageal hiatus, which may lead to food reflux, accompanied by chest pain, acid reflux and other symptoms.

3. Weakened esophageal motility

. Esophagitis, esophageal stricture and other reasons may lead to slow esophageal motility, resulting in gastroesophageal reflux.
