Abstract:
Non-erosive gastroesophageal reflux disease (NERD) is still underappreciated type of gastroesophageal reflux disease (GERD). It is not a homogenous group of patients with real reflux, oversensitivity of esophagus and functional dyspepsia. Nowadays often in classifications of GERD patients with NERD are omitted. Many endoscopic lesions are found in esophagus in NERD, especially color change of mucosa. Erythrema is nowadays taken into account. Unequivocal are also opinions about histological image. Many histological lesions are found but not a specific lesions were typified. Probably it is the best to associate NERD with clinical symptoms, endoscopic and histological image.
