Acidity: The stomach is usually protected from the acid by a mucous layer. In some cases, due to excess acid production, the mucous layer gets eroded, which leads to complications like acidity, GERD, heartburn, peptic ulcer, and Zollinger Ellison syndrome.

Gastroesophageal reflux disease (GERD): It is a condition that occurs when stomach acid frequently flows back into the food pipe (oesophagus). This backflow (acid reflux) irritates the food pipe and causes heartburn.

Duodenal ulcer: It is a painful condition followed by the development of sores or ulcers in the duodenum or stomach lining (first part of the small intestine, i.e., the duodenum).

Zollinger Ellison syndrome: It is a rare condition in which a gastrin-secreting tumour of the pancreas causes excessive acid production leading to peptic ulcers.
