The clinical team believe your medical care will be helped if you have a gastroscopy, as this will allow them to see your oesophagus, stomach and the first part of your small bowel.
A gastroscopy is also known as an endoscopy or OGD (OesophagoGastro-Duodenoscopy). The gastroscopy will be used to investigate the cause of your symptoms and in some cases, it can also be used to treat any problems seen.
This page gives you information about having a gastroscopy and explains the risks and benefits related to the procedure. This will help you to decide if you would like to go ahead with the procedure and whether you would like to have sedation.
