What You Need To Know About Getting A Colonoscopy
- 04 Feb 2019
Colonoscopy is a procedure employed to check the lining of your colon and gauge any problems in your large intestine (colon) and rectum. It is one of the most accurate tests for detecting abdominal and rectal cancers, and is frequently used as a screening tool to test for gastrointestinal diseases including Polyps (abnormal growths in the lining of your colon).
Your doctor may suggest a colonoscopy if you begin to display symptoms like:
A Colonoscopy usually involves the insertion of a flexible tube into your rectal cavity, called a Colonoscope. This tube is half an inch in diameter and around 5 ft in length. The end that goes into your body has a tiny camera and light attached to it, which allows your doctor to see the inside of your system.
For the test, you will be given medication which will relax you and make you a little drowsy. You will be asked to lie down on your left side and then gradually, the tube will be inserted. The doctor will navigate the tube till it reaches your big intestine. You might be asked to move a little sometimes, to adjust the colonoscope.
In certain cases, if the doctor notices any abnormality, tiny pieces of your tissue are taken using a 'snare', for further testing. This is called a biopsy. The test will take around 30 minutes and once done, the doctor will gradually take the tube out, carefully examining the abdominal lining.
You can rest a little after the procedure and then leave though you will be advised not to drive or exert yourself soon after the test.
A colonoscopy poses a few risks, such as the development of tears in the lining of your colon or rectal wall, allergic reactions to the sedatives used during the procedure and bleeding in the area where the tissue sample was taken.
Here are a few precautions you can take before you undergo a colonoscopy:
You can speak to your right after the procedure, for some do's and don'ts for the next few days. They will mostly be either Dietary (what not to eat to aggravate discomfort) and Medications (which medicines not to take for some time, based on your medical history).
It is common to find some bleeding after a colonoscopy. Alert your physician if you experience any post-procedure discomforts.
After the age of 40 years, it is advisable to get a Colonoscopy every 10 years. However if yours first test yielded polyps, you should get it done every 5 to 10 years. Based on your results, you will be asked to do another procedure, or follow a rigorous surveillance routine as prescribed.
Contact your physician if you experience heavy bleeding for a long period of time, or get chills, fever, or severe abdominal cramps.
