It allows your doctor to have direct vision of the colon or pathological changes inside, such as tumors, ulceration or polyps. Your doctor will take a biopsy for pathological examination and may perform polypectomy and therapeutic haemostasis when necessary.  \nWhy is Colonoscopy performed?  \n1. Change in the bowel habits  \n2. Chronic diarrhea  \n3. Unexplained abdominal pain  \n4. Blood in stool  \n5. Anemia  \n6. Colorectal polyps or tumors  \n7. Colon cancer screening  \nSource: [https://www.mayoclinic.org/-/media/kcms/gbs/patient-consumer/](https://www.mayoclinic.org/-/media/kcms/gbs/patient-consumer/)[ ](https://www.mayoclinic.org/-/media/kcms/gbs/patient-consumer/)[images/2013/11/15/17/44/ca00083_-ds00035_-ds00669_-ds0070](images/2013/11/15/17/44/ca00083_-ds00035_-ds00669_-ds0070)[ ](images/2013/11/15/17/44/ca00083_-ds00035_-ds00669_-ds0070)[5_-ds00824_-ds01195_-my00621_im04054_hdg7_colonoscopyt](5_-ds00824_-ds01195_-my00621_im04054_hdg7_colonoscopyt)[hu_jpg.jpg](hu_jpg.jpg)  \nOutcomes  \nColonoscopy can check the lower digestive tract. It will allow a biopsy to be taken if any abnormality is detected.  \nProcedures  \n1. You have to lie on your left side with both knees bending towards your chest.  \n2. Doctor may prescribe sedation or anaesthetic medication according to your condition.  \n3. Doctor will pass the colonoscope through the anus into the colon. It is normal if you feel mild abdominal distension and urging of the bowel during the procedure.  \n4. The procedure usually takes about 30 minutes.  \nPossible Risks and Complications  \nBefore examination  \n- Laxative for bowel preparation may cause nausea, vomiting, abdominal pain or distension, etc. During examination  \n- Injection of sedation may cause hypotension or respiratory difficulties. For severe cases, anaphylaxis and anaphylactic shock may be developed. The probability of developing such symptoms is higher for the elderly.  \n- Perforation (1:1000); the probability of developing major complications is higher for those clients  \nwho needs to have a therapeutic procedure (e.g. polypectomy, endoscopic haemostasis, dilatation and insertion of stent) .  \n- Perforation of the bowel will lead to peritonitis. A remedial surgical procedure may be required. After examination  \n- May experience abdominal pain or distension, etc. It will improve about one hour after examination.  \n- Bleeding may occur after polypectomy (1:1000), which usually happens within 24 hours of examination.  \n** The risks listed above are in general terms and the possibility of complications is not exhaustive. Please understand that even though all procedures are carried out with utmost professionalism and care, this does not rule out the possibility of complications arising. In the event of peripheral organ damage or post-operative haemorrhage or leakage, further operations may be required.  \nPre-procedure Preparations  \n1. The procedure and possible complications will be explained by the doctor and a consent form must be signed prior to the procedure.  \n2. Please inform the doctor if you are or might be pregnant.  \n3. Please inform the doctor and nurse all your past medical history, previous surgical operations and any complication with drug or anaesthesia.  \n4.
