Colonoscopy Procedure: Preparation And How It’s Done!



First of all, colonoscopy or coloscopy is simply a procedure that allows your surgeon to examine the colon and rectum area, from the inside. It’s frequently done in the hospital or in an endoscopic operation room and more specifically, on an outpatient basis. Why is coloscopy done? Many times, a coloscopy scan may be done to evaluate symptoms such as abdominal pain, changes in bowel habit, rectal bleeding, and to screen any occurrence of colorectal cancer in patients. But before you even consider a colonoscopy screening test, it’s important to alarm your doctor on any special medical conditions you may have, such as pregnancy, lung condition, heart condition, and any allergies you may experience with any medication.





The procedure many times is performed by a doctor highly experienced in the coloscopy field, and the screening test lasts anywhere between 30 to 60 minutes, at least. Medications are inserted into the vein to make you feel more relaxed and drowsy, and then your doctor asks you to lie flat on your left side on the examining table. Afterwards, the doctor inserts a soft, bendable scope into the anus and further advances into the rectum and colon area. Sometimes, your physician may ask you to change position occasionally to enable him to move his scope around the colon area more effectively.


The scope tube also blows air into the colon so that it can expand more, and so that the doctor can get a clear view of what is going on. Many patients usually experience mild cramping, bloating and some gassiness during the procedure, which can be further reduced by taking slow deep breaths during the screening test. After the doctor is done, the scope is slowly withdrawn while the lining of your bowel is closely examined. If the doctor fears something is abnormal, small layers of tissues can be removed for further analysis–known as a biopsy test. Also any kind of abnormal growths and polyps identified are usually removed, as well. Although many times, coloscopy scans allow effective diagnosis and treatment without the sequence for a serious procedure.





After a coloscopy, you will be allowed to stay in a recovery room for about 30 minutes for more observation until all the sedation given upon the test has worn off. This can last about 1-2 hours. You may also experience some cramping and gassiness, although these feelings usually end rather quickly, and then you can eventually resume your normal diet as you wish. Because the sedatives given by the doctor can easily impair your reflexes, make sure you don’t drive or operate any machinery until the next day. So find someone to drive you home after the test.


Likewise, if you do not remember anything your surgeon told you about the examination or follow-up instructions, make sure you call your surgeon that very day or the next in order to be aware what you were supposed to do in the first place. Although just in case traces of polyps were found, you will need to see your surgeon some other time for another coloscopy scan, after which he or she may decide on the frequency of your next coloscopy test exams.



Above all else, many times a coloscopy test is done to check for symptoms such as abdominal pain, rectal bleeding, changes in bowel habit and more. During the procedure, patients may experience some gassiness and bloating, although this is reduced effectively by the sedatives given by the doctor and by taking slow deep breaths. After the coloscopy test is done and all the cramping and gassiness sensation have cleared, you can in turn go ahead and resume your diet. And if you have any questions or have any doubt about your coloscopy scan, it’s important you check with your surgeon all the time to save an appointment for may be another coloscopy test.
