Gastroscopy or OGD is a diagnostic endoscopic camera test that visualises that oesophagus, stomach and the duodenum. The camera is placed via the mouth and the test is performed using a local anaesthetic throat spray to numb the mouth, sedation can also be given via an injection if required. The test is organised for symptoms that include reflux, difficulty swallowing (dysphagia), weight loss, upper abdominal pain, anaemia and vomiting. During the test it is possible to take biopsies to aid diagnosis and perform treatments for conditions such as peptic ulcers.
If a patient wishes to have sedation they need to have a responsible adult stay with them overnight and are not allowed to drive for 24 hours.
