Human: I've heard that a colonoscopy is a painless procedure, but I'm afraid of pain. Is that true? Assistant: 
It depends on the person, but in general, most people find colonoscopies to be relatively painless. The discomfort can vary from person to person, and there are some things you can do to make it more comfortable. For example, if you're nervous about the procedure, you can ask your doctor for an anesthetic or sedative to help relax you. You can also try to distract yourself by listening to music or talking with friends or family members during the procedure.
