Colonoscopy is an examination of the entire colon down to the small intestine.

It uses a small, flexible, bendable tube with a camera and light at the end into the anus. Doctors can diagnose what they find, such as inflammation, tumors, and cancer from organs in the lower digestive tract. They can even perform surgery to remove some tissue for pathological examination in a laboratory.

Does a colonoscopy hurt?

Many people are concerned about the pain caused by having to insert this device into their rectum. However, this examination can be performed using sedation or intravenous local anesthesia. The patient is relaxed and unconscious during เว็บพนันออนไลน์ UFABET สมัครง่าย โปรโมชั่นมากมาย the examination. An anesthesiologist will monitor their blood pressure, pulse, and heart rate. After that, the doctor will slowly move this endoscope through the rectum until reaching the large intestine and small intestine to examine all abnormalities in that area.  

How long does a colonoscopy take?

Colonoscopy usually takes about 30-60 minutes. After the patient is given a sleeping pill, the doctor will look at any abnormalities in the rectum, colon, and the lower part of the small intestine through a screen, which is the image from the camera device that is inserted. In addition, air may be blown in to make the image clearer or to stop the bleeding if there is any. However, after the procedure is complete, the patient must rest in the hospital for about 2-3 hours to monitor for any complications such as bloating or stomach pain. If there are no abnormalities, the doctor will allow the patient to go home, but the patient should not drive themselves. A caregiver or relative must pick them up. The patient can drive a vehicle after the colonoscopy for 1 day.
