Colonoscopy In Depth

Colonoscopy is a test that allows doctors to look at the inner lining of your large intestine (colon and rectum).  The physician uses a thin, flexible tube called colonoscope to look at the colon.  This helps find ulcers, colon polyps, tumors, and areas of inflammation or bleeding.  During a colonoscopy tissue samples can be collected (biopsy), for testing and abnormal growths can be removed.  It can also be used for a screening test to check for cancer or precancerous growths in the colon or rectum (polyps).  A small camera is also attached to the tube used for the colonoscopy so the large intestine can be seen by the physician.  Before this test you have clean out your colon.  This is called a colon prep.  This takes one to two days, depending on the physician's recommendations.  For most people the prep is worse than the actual colonoscopy.  The colon prep causes loose and frequent stool, or diarrhea, so your colon will be empty for the test.  The colon prep can be uncomfortable and you will most likely be hungry, because you will be on a clear, liquid diet.  A colonoscopy is done for the following reasons:

  • To check for colorectal cancer or polyps - This test is done particularly in people over 50 years of age, who are most likely to acquire colon cancer.  You may need to be tested more frequently, if you have more risk signs.  Talk to your physician about this.
  • To check for the cause of blood in the stool or rectal bleeding
  • To check for the cause of dark or black stools
  • To check for the cause of chronic diarrhea
  • To check for the cause of iron deficiency anemia
  • To check for the cause of sudden, unexplained weight loss
  • To check the colon after abnormal results from a stool test or a barium enema test
  • To watch or treat inflammatory bowel disease (IBD)
  • To check for the cause of long-term, unexplained belly pain
After the colon prep you will go and they will give you a sedative before doing to procedure.  They will then send off any tissue samples for testing, and you will return to the doctor for the results.  This is a crucial tool in diagnosing.  It isn't just used if you have been sick, if you are at risk talk to you doctor about having this test, especially if you are over 50 years of age.  Stay Informed!  http://www.webmd.com/colorectal-cancer/colonoscopy-16695
