It can help diagnose the cause of symptoms and, in some cases, allow treatment during the same procedure.

What is Endoscopy?
An endoscopy is a procedure that allows a doctor to look inside the body using a thin, flexible tube with a camera and light (endoscope), commonly used to examine the digestive tract, such as the stomach (gastroscopy) or large intestine (colonoscopy). It can help diagnose the cause of symptoms and, in some cases, allow treatment during the same procedure.
Depending on the type, an endoscopy may be performed under sedation or local anaesthetic, and often requires specific preparation beforehand, such as fasting or bowel preparation, to allow clear views of the area being examined.
