[|Human|] My gastroengerologist has referred me for surgery to repair paraesophogeal hernia.  He indicated an urgency because of the possibility of vomitting in my lungs and suphocating.  I was kind of in shock during the interview and I wasnt able to ask how that would be even possible -- do you know?
[|AI|]  Hi. Para esophageal hernia can cause varied symptoms. One of them may be gastroesophageal reflux disease meaning the stomach contents, particularly the acid comes up in the esophagus causing burning, difficulty or painful swallowing and so. It would have beneficial for me to know your symptoms, why the investigations were done to diagnose this in the first place. The possibility of vomiting in the lung casing suffocation is very remote. So urgency is not required on this ground.
