The muscular tube that transports food and liquids from your mouth to your stomach is known as the oesophagus. You may not realise you have a problem with your oesophagus until you swallow something too big, too hot, or too cold. It's also possible that you'll notice it if anything is amiss. You may experience discomfort or difficulty swallowing.
GERD is the most frequent esophageal ailment (gastroesophageal reflux disease). A muscle at the end of your oesophagus does not seal correctly in people with GERD. This causes stomach contents to flow back into the oesophagus, causing irritation. The oesophagus can be damaged by GERD over time. Heartburn, malignancy, and eosinophilic esophagitis are among the other issues.
