Gastroscopy
Learn about a medical procedure that examines the upper gastrointestinal tract.
What we do
A gastroscopy is a medical procedure performed by a gastroenterologist to examine the upper part of the gastrointestinal tract, which includes the throat, esophagus, stomach and duodenum (the first part of the small intestine).
What to expect
During the procedure, a thin, flexible tube with a camera, called a scope, is inserted into your mouth and carefully passed down through your throat into your digestive system.
This allows the physician to look at the area and take pictures. In some cases, a small tissue sample, called a biopsy, may be taken during the procedure for further examination.
Gastroscopies help diagnose and monitor conditions such as:
- Acid reflux
- Gastrointestinal cancer
- Celiac disease
- Crohn's disease
- Ulcers
- Swallowing disorders
Depending on your specific needs, we may either numb your throat or use a sedative to keep you comfortable during the procedure.
It is important to have someone who can bring you home after the procedure, as the sedative effects can impair your ability to travel safely.
What to bring
- Health (OHIP) card or valid health-care coverage
- Someone to help you get home, as the sedation may impair your ability to travel safely
