Gastroesophageal reflux disease (GERD): It occurs when stomach acid frequently flows back into the food pipe (oesophagus). This backflow (acid reflux) irritates the food pipe and causes heartburn. Symptoms include heartburn, sour or bitter taste in the mouth, and difficulty swallowing.

Peptic ulcers: Peptic ulcers are sores that develop on the lining of the stomach and intestine due to erosion of stomach's protective lining. Symptoms include nausea, changes in appetite, bloody or dark stools, unexplained weight loss, vomiting, and indigestion.
