A colonoscopy is performed as a diagnostic tool to determine the cause of sudden colon-based symptoms. It is also used as a preventative screening tool to catch the early onset of several serious conditions of the large intestine that occur naturally as people age.
Common Symptoms 

The colon completes digestion and waste expulsion processes. When it functions properly, the body receives all of the nutrients and fluids it needs to function. When the colon malfunctions for any reason, people can experience:

– Nausea
– Gas and Bloating
– Constipation or Diarrhea
– Blockages
– Dull or severe pain
– Bleeding
– Nutrient malabsorption
– Immune system dysfunction
Colon Health 

Sometimes the colon becomes unhealthy from the accidental consumption of foods, medicines or objects that upset the gut flora balance within the colon, cause some sort of damage or create allergic and non-allergic reactions. The most common causes of poor colon health are:

– Tears and perforations
– Abscesses, polyps and ulcers
– Inflammation and/or bleeding
– Damaged, missing or overwhelmed healthy gut flora
– Microorganisms and parasites
– Infections from any causes
– Cancer of the colon or nearby organs
Colonoscopies Save Lives 

In poor colon health scenarios, men, women and children can experience permanent damage or die if their conditions go untreated for long. Ulcers and polyps can develop into colorectal cancer. Unprotected torn surfaces can become infected and potentially cause blood infection and even gangrene.

The process for an acute symptom diagnostic procedure and a colonoscopy screening is typically the same: A patient uses a medication to clean out the bowel. The gastroenterologist places the patient under sedation and inserts a gentle, flexible tube into the colon. Then the doctor passes a camera on the end of fibre optic line through the tube to observe the interior lining from the bottom of the small intestine all of the way out of the body at the anus. Some gastroenterologists also remove small pieces of colon tissue to conduct biopsies to check for certain diseases, microorganisms and cancers. In some cases, polyps are also removed or treatment is conducted on abscesses and tears.

In situations when an invasive procedure is not immediately possible, some gastroenterologists order a CT X-ray scan of the colon to get a rough view of things that can be easily detected via this method, such as blockages, inflammation and non-cancerous/cancerous growths. Patient preparation is the same, but there is limited invasive movement through the colon. Instead, a doctor inserts a device that gently inflates the colon and then uses CT scanning equipment. The scans are fed into a computer program that creates a 2D or 3D representation of the colon on screen for diagnostic study.

People visiting, exploring or living in Singapore have no need to worry about receiving the care they need if they experience acute or chronic symptoms. There are plenty of health facilities that can perform a colonoscopy in Singapore and experienced doctors that can provide accurate diagnoses based on results.
