Gastric acid secretion is a fundamental component of the digestive system. Gastric acid, primarily produced by parietal cells, plays a crucial role in the digestive system and its functions encompass sterilizing food, promoting absorption, aiding digestion, and serving as a defense mechanism against pathogens. However, anomalies in its secretion can arise through over-secretion of acid or breaks in the protective mucosal barriers (gastro-protective mechanisms disruption).
