What does colonoscopy check

Our human body is made up of many intestines, which are divided into different parts, so their names are different. The treatment methods for diseases in different parts are also different. Therefore, when many patients often feel abdominal pain, doctors will recommend colonoscopy, so that they can specifically see which part of the intestine has problems. So what is colonoscopy?

The human large intestine includes the cecum, colon, rectum, and anal canal. Colonoscopy usually refers to colonoscopy, also known as colonoscopy. Any disease occurring in the large intestine can be examined by colonoscopy. Colonoscopy can detect colorectal tumors, inflammation, bleeding, polyps and other diseases. The intestine belongs to the digestive system in terms of physiological function, so colonoscopy is mostly performed by endoscopists in the gastroenterology department, and patients visit the gastroenterology department for treatment. Oral laxatives are required before colonoscopy to clear intestinal waste, which is more conducive to observation during colonoscopy.
