the answer to your question is "yes and no. " each individual physician sets his or her own criteria under which he or she will perform a procedure. for example a dermatologist might be willing to surgically remove a mole from your face right in the exam room while a plastic surgeon may require you to have it done in an operating room. it's possible you will find a doctor who is willing to perform a colonoscopy without iv sedation. however iv sedation is the standard today and you will tolerate the discomfort of the colonoscopy better with a little sedation on board. i'm not sure why you're unwilling to get an iv. when i was an operating room nurse many of my patients expressed severe needle anxiety that made starting an iv difficult for them. if this is the case for you please know you can receive oral sedation before the iv start. this usually makes the process tolerable for even the most needle-phobic person. wishing you well!
isa an iv always given for a colonoscopy? . i refuse to have an iv inserted. can the doctors still do a colonoscopy without it?
