What kind of examination is done when checking the intestines

Intestinal disease can be said to be a disease that is difficult to detect. Generally, we can only judge based on the discomfort reactions of the intestines and the body. If you want to know whether your intestines are sick, you need to use some relevant medical equipment for examination. The most common bowel examination is a colonoscopy. Most diseases can be diagnosed through colonoscopy. So, what should we pay attention to when undergoing a colonoscopy?
