NERD: an umbrella term including heterogeneous subpopulations.

Nature reviews. Gastroenterology & hepatology - 1 Jun 2013

Savarino Edoardo, Zentilin Patrizia, Savarino Vincenzo

Abstract excerpt

Nonerosive reflux disease (NERD) represents the more common phenotypic presentation of GERD and comprises patients who have typical symptoms without any mucosal breaks at endoscopy. However, these patients are markedly heterogeneous from a pathophysiological point of view and should be correctly classified by means of 24 h impedance-pH testing, which enables detection of both acidic and weakly acidic reflux and...
