subject: Colonoscopy - Understanding The Importance Of Preventive Screenings [print this page] Understanding the importance and purpose of a colonoscopy can help you to eliminate fear that is commonly associated with this procedure. A colonoscopy allows your doctor to examine the lining of your large intestine (colon) for any abnormalities. It is an outpatient procedure that your doctor may perform to diagnose and treat, when possible, certain diseases of the lower gastrointestinal (GI) tract, which includes the rectum and colon. You may need a colonoscopy to evaluate a variety of problems, including:
*Abdominal pain
*Anemia (low red blood cells)
*Blood in the stool
*Change in bowel habits
*Screen for colon cancer
*Unexplained weight loss
Colon cancer is the third leading cause of cancer deaths in the United States with approximately 150,000 new cases diagnosed each year with 50,000 people dying from this disease. It has been estimated that increased awareness and screening would save at least 30,000 lives every year. The American Society for Gastrointestinal Endoscopy encourages everyone over 50, or those under 50 with a family history or other risk factors, to be screened for colon cancer.
The Procedure
A colonoscopy is a well-tolerated procedure that rarely causes much pain. During the procedure you may feel pressure, bloating or cramping, but your doctor will give you a sedative or painkiller to help you relax and better tolerate any discomfort. During the procedure you will lie on your side or back while your gastroenterologist advances an endoscope along your large intestine to examine the lining. Your doctor will examine the lining again as he or she slowly withdraws the endoscope. The procedure typically takes less than 45 minutes, although you should plan on two to three hours for waiting, preparation and recovery.
Preparing for Your Colonoscopy
Before your colonoscopy it is important to inform your gastroenterologist in Philadelphia about any special medical conditions, such as:
*Pregnancy
*Lung and heart conditions
*Allergies to medications
*If you have diabetes or take medications that may cause blood clotting
Do not stop taking any of your medications without first consulting your doctor. There may also be some diet or fluid restrictions before your colonoscopy as well. These restrictions will vary according to your gastroenterologist's instructions.
Additionally, you may be asked to limit or eliminate solid foods for a few days before your colonoscopy. You will also be asked to take laxatives by mouth to clean out your colon to prepare it for the exam. One or two enemas will be given to you before your procedure. When you take these, try to hold the enema solution for at least five minutes before releasing it.
After Your Colonoscopy
Once your procedure is complete you will need to remain in the recovery room for approximately 30 minutes for observation. You may experience some cramping or a sensation of having gas, but this typically passes quickly. Be sure to have a responsible adult drive you home after your procedure, as it is unsafe to drive or operate machinery for about 8 hours after your procedure due to the sedative used. You will also be able to resume your normal diet once the procedure is complete.
Talk to your Philadelphia, Bala Cynwyd and Langhorne gastroenterologist for more information on a colonoscopy and to find out if you are in need of this exam.
