Inflammation specifically affecting the innermost lining of the stomach, the deepest layer of stomach tissue.
From Greek 'eso-' (innermost) plus 'gastris' (stomach, from 'gaster') plus '-itis' (inflammation). This medical term specifies inflammation at the deepest stomach layer.
The stomach lining has multiple layers, each with different functions—deep inflammation is more serious than surface inflammation because it affects the stomach's protective mechanisms, so doctors need the word 'esogastritis' to communicate severity accurately.
