Professional singers perform singing tasks requiring rapid changes of subglottal pressure with consistent use of the diaphragm.
They regularly activate the diaphragm when there is a need for a rapid decrease in subglottal pressure. This causes an abrupt and prolonged increase in intra-abdominal pressure.
In this study, researchers from Rome, Italy, describe the occurrence of stress-induced gastroesophageal reflux disease (GERD) in 4 professional singers.

The team found that the reflux symptoms, which occurred in these patients during vocal performances, were an important obstacle to the movement of the respiratory muscles.
Dr Giovanni Cammarota's team concluded, "To our knowledge, these are the first case reports of worsening of GERD symptoms in professional singers during performances".
