Why are some docs, incl here, so negative about unsedated colonoscopy? Mine was a wonderful learning experience w/no side effects!

Stress!: When patients are in pain, it causes significant stress on the patient and also your doctor. No doctor likes to see their patients in pain. Pain can cause heart attacks.... Also it may cause your doctor not to make maneuvers that he would have otherwise done because of not wanting to induce more pain! it takes two to tango! your doctor is a major element here too! ...Read more

On average how long does a colonoscopy and endoscopy done at the same time take? Will the sedation cause funny behavior after like anesthesia does?

Short sedation: EGD(upper endoscopy) can be as short as 5 minutes, with biposies most of them accopmlished in ~15 min. Colonoscopy takes longer, most fit in the timeframe of 20-40 minutes.

Yesterday I had colonoscopy with anesthesia (passed out for the whole procedure) and today my lungs hurt. Why, what's the connection?

R/O COMPLICATION: Often times Propofol is used for anesthesia it is very potent. Rarely when you are recovery from anesthesia, fluid may get into the lungs. This is referred as aspiration. I recommend following up with your GI doctor. If symptoms worsen acutely or fever develops, get immediate evaluation and X-ray to rule out aspiration Pneumonia. ...Read more
