Hydrochloric acid (HCl) plays a crucial role in digestion by breaking down food in the stomach. It activates pepsin, an enzyme that aids in protein digestion, and creates an acidic environment necessary for various digestive enzymes to function optimally. However, excess hydrochloric acid can cause discomfort due to its corrosive nature. It may lead to conditions like acid reflux, indigestion, or heartburn. The excess acid can irritate the esophagus and contribute to the development of ulcers. Maintaining a balance of stomach acid is vital for proper digestion, as both insufficient and excessive acid can lead to digestive issues.
