What is grade c oesophagus?

Grade C esophagus refers to a classification in the Los Angeles classification system for esophagitis, specifically for gastroesophageal reflux disease (GERD). It is characterized by moderate to severe erosive changes in the esophageal lining, with at least one erosion extending over a length greater than 5 mm but not involving the entire circumference of the esophagus. This grade indicates significant inflammation and damage, which may require medical intervention to manage symptoms and prevent complications.
