Should i consult an anesthesiologist for colonoscopy or no sedation?

Sedation: In general, this procedure is performed with conscious (or moderate) sedation, which is usually a mixture of IV anti-anxiety + pain med. This makes the procedure easier for you, as well as for the performing doc, because it relaxes the colon, making passage of the scope easier. The sedation in most cases is administerd by the performing doctor, and an anesthesiologist is not required.

Get sedated: I usually recommend sedation for my colonoscopy patients. It makes it better/easier for both parties. Having said that, if you are strongly against sedation, here are a few general rules: it is more difficult to perform colonoscopies on thin females. The ideal candidate for unsedated colonoscopy is a short, slightly overweight male.
