Detailed explanation-2: -Acid reflux occurs when the sphincter muscle at the lower end of your esophagus relaxes at the wrong time, allowing stomach acid to back up into your esophagus. This can cause heartburn and other signs and symptoms.

Detailed explanation-3: -Heartburn and acid reflux, also known as gastroesophageal reflux disease (GERD), occur when the lower esophageal sphincter (LES) muscle, located at the bottom of your esophagus, weakens or relaxes abnormally allowing acid to flow back into your esophagus.

Detailed explanation-4: -When stomach acids repeatedly back up into the esophagus, they can injure its sensitive lining. That injury can lead to painful inflammation called esophagitis. Eventually, the acid wears away at the esophagus, causing bleeding.
