👉 Gastro-oesophagitis, also known as gastroesophageal reflux disease (GERD), is a chronic condition in which stomach acid flows back up into the esophagus. This can cause discomfort and pain in the chest or throat, along with other symptoms such as heartburn, nausea, and difficulty swallowing. There are several factors that contribute to GERD, including stress, anxiety, smoking, alcohol consumption, and certain medications, but it is not always caused by these factors alone
