Lubricating jelly is applied to the tube before it is inserted into the rectum. As the tube is advanced through the colon, you may experience a feeling of having to have a bowel movement. This is normal. You may also experience cramping and a feeling of fullness. This due to the physician inserting air into the colon to better visualize the area.
Suction is also available to remove any retained liquid or stool in the colon.
You will not feel this. If you experience any severe discomfort, please let the nurse or physician know immediately. You will receive enough medication to keep you comfortable. It is at this time when the most thorough examination is done. Biopsies are taken or polyps are removed at this time.
