I’ve done it without any sedation countless times (I have to have very frequent ones because Lynch syndrome, which is a genetic condition that, among other things, increases your risk of developing colon cancer, as well as many other cancers, too, at a much younger age than they typically occur). I had to be almost dragged to get my first colonoscopy over 11 years ago, and I had it with sedation because it was what I had been recommended by the doctor given my anxiety levels. I believe that only Propofol was used and I have no recollection whatsoever about it but I do remember feeling out of it for a number of hours afterwards. My fiancé, who I was living with at the time, and who made me see a doctor in the first place (probably saving my life) was the one who suggested that I try and get it without any sedation. He came with me to the following pre-test appointment and we had worked out a bunch of questions for the doctor to make me feel as comfortable as possible (I was not terribly fond of the idea of having a few feet of scope inside me in front of strangers; I was never shy with my fiancé sliding just about everything imaginable up my butt, including his fist, but I knew that the same comfort levels would never be achieved with any healthcare provider, no matter how professional and skilled, and I have been very lucky in that regard). The doctor agreed to do the procedure without me having any sedation and explained that it was still necessary to have an IV access placed in case I changed my mind about being awake and because it was hospital policy in general, should a patient require emergency meds given IV. It was not a problem for me, and it eased my concerns about the whole thing.
Over a decade later, this has become a familiar ritual for every colonoscopy and just about any other procedure of the same type (upper GI scoping without sedation is very hard for me and I hate the feeling of being just about to vomit for the duration of the test).
I’ve had the same doctor for a number of years now and it has helped me become more comfortable with all of these rather invasive experiences that I have to deal with solo, after my fiancé passed away.
Some scope days are better than others and some are quite difficult, but it’s because of the amount of inflammation and tension that I have in my lower GI tract (not Lynch related, but IBS related… I won the organ lottery for this nice combo 🤦🏻♀️). Getting a colonoscopy when I have a flare up hurts, but I dislike the feeling of the anesthesia aftermath worse and I like not having to have a ride home every time, which is required at my hospital if you are put under. I can’t say that with certainty but it is probably the case in most hospitals and clinics and definitely something to consider/inquire about.
I would suggest that you talk to your doctor about your concerns and see what they say. Communication is key and you will hopefully have a great healthcare team that can make you feel better about the procedure in its entirety (the prep is way worse, and many options are available, so ask about it; that is something that you have to be awake for, barring very serious circumstances). Feel free to message me if you like, I am more than happy to answer questions if I can, since it is a daunting process and I would have not been able to get through it without the support of others who, from time to time, have been online strangers who shared the same diagnosis or had the same distaste for anesthesia.
Best of luck,
