👉 Pseudogastrula, also known as a pseudogastric stenosis or pseudogastroesophageal reflux disease (PGED), is a condition where there is an obstruction in the opening between the stomach and esophagus. This can cause discomfort, pain, nausea, and even vomiting when food enters the stomach. The exact cause of this condition is not fully understood, but it is thought to be caused by either the narrowing or obstructions within the esophageal wall itself
