What Are Oesophageal Disorders?

The oesophagus is a muscular tube that connects the mouth to the stomach. Oesophageal disorders are a few of the many types of gastrointestinal (GI) conditions that affect the digestive system. Common oesophageal disorders include:

Gastroesophageal reflux disease (GERD)

Gastroesophageal reflux disease (GERD) refers to the backflow of stomach acid into the oesophagus. The acid may irritate the lining of the oesophagus, causing inflammation and ulcers. GERD also often leads to an uncomfortable burning feeling (heartburn) in the chest, neck, or throat.


Oesophagitis is the inflammation of the oesophagus. Causes include GERD, medications, viral or fungal infections. Patients may experience heartburn, chest discomfort, pain on swallowing and even difficulty swallowing. Treatment depends on the underlying cause, but often includes medication to suppress acid production in the stomach.


Dysphagia is a condition where there is difficulty swallowing. There is the sensation of food or liquid being stuck in the chest or neck. There are many causes of dysphagia, but it is important to check if there is any blockage in the oesophagus eg due to strictures ( narrowing of the oesophagus ).


Achalasia is a severe form of swallowing disorder where the muscle of the oesophagus do not contract well and the lower sphincter is unable to relax. This results in dysphagia. Treatment is aimed at loosening the lower sphincter in order for food and liquid to pass through more easily.

Oesophageal cancer

Oesophageal cancer develops in the oesophagus when non-cancerous growths mutate into their cancerous forms. Treatment options generally depend on the severity of cancer and can include surgery or chemoradiation therapy.
