Giant hiatus hernia causes multiple symptoms

A previous diagnosis turns out to be not quite so simple
Cough

Peggy, a 75-year-old woman, presents to her GP with worsening cough after her evening meal and in bed at night.

She is unable to sleep lying flat because of coughing.

She has a longstanding background of heartburn and regurgitation for which she takes a PPI in the morning and at night.

Previous endoscopy has reportedly shown a 5cm sliding hiatus hernia without esophagitis.
