Why did my doctor recommend a colonoscopy?(ref 1)
The most common reasons for a colonoscopy are to screen for colon cancer, or to look for possible causes of the following signs and symptoms:
How long will the procedure take?(ref 2)
A colonoscopy usually takes less than 30 minutes
Is the procedure painful?(ref 3)
Colonoscopy is sometimes quite easy, causing very little discomfort, but many people have significant discomfort if they try it without sedation. However, the choice of sedation or (no sedation) should remain a shared decision between attending physician and patient.
When will I get the results?(ref 4)
Some results from a colonoscopy are available immediately after the procedure. After the anesthesia has worn off, the doctor will share results with the person or a designee. Biopsy results take a few days to come back.
