Screening: A flex-sig is usually done in the office as a preliminary screening procedure. It is also useful as a follow-up if you have had polyps removed in the lower colon. Is is also useful to re-evaluate colitis and you response to treatment.

Depends!: Very few physicians perform sigmoidoscopy anymore (only checks half the colon and no sedation!). Colonoscopy is usually done with sedation or anesthesia. The procedure itself is usually not uncomfortable. The cleaning out preparation can be arduous. Colonoscopy is 50 times more life saving than a mammogram!

Can you tell me about having a flexible sigmoidoscopy or a colonoscopy ?

Both look at: The lower colon but the colonoscopy looks at the entire colon. Preps are different, colonoscopy usually requires sedation and thus someone to drive home, but flex sig can be done in office without sedation and you can resume normal activity right away. Indication are different for each so it depends on the reason you are having the exam in the first place.
