Colonoscopy Procedure | GI SpecialistsWhat Is a Colonoscopy?

The colon, also known as the large intestine, is the last part of the digestive system. It is responsible for the absorption of minerals and water from solid waste before it is eliminated from the body.

In order to examine the colon, doctors must perform a colonoscopy. This procedure involves the use of a flexible tube equipped with a light and video camera that can travel the length of the colon. Gastroenterologists can look at this footage to determine if there are any abnormalities that may need to be treated.

Colonoscopy Procedure | Checking for Colon Polyps or Colon CancerWhat Are the Health Benefits of Undergoing a Colonoscopy?

One of the main purposes of a colonoscopy is to check for colon polyps or colon cancer. Polyps are not innately cancerous; however, they may have the potential to become cancerous. Many times, they can be removed during a colonoscopy in a process called polypectomy.

A colonoscopy also allows the physician to examine problems such as:

  • Blood loss
  • Abdominal pain
  • Rectal pain
  • Change in bowel movements
  • Active bleeding in the large intestine

In addition, GI doctors can utilize other tools during a colonoscopy to take samples of tissue from abnormal-looking growths so that they can be tested to see if or what type of surgery may be necessary.

How to Prepare for Your Colonoscopy

Your physician will provide you with a detailed set of instructions on what to do or not to do before your procedure takes place. Typically, you will be on a clear liquid diet before a colonoscopy and the physician may give you additional instructions regarding medication.

It’s important to arrange for a licensed driver that is not a taxi driver to take you home after your procedure. You will be under some anesthesia during the procedure and therefore will not be fit to operate a vehicle or any sort of machinery afterward.

Your Experience During & After a Colonoscopy

To ensure that you are as comfortable as possible during the procedure, you will be given an IV with medication to make you feel at ease. You will be awake during the procedure but will likely not remember much of the experience overall.

A colonoscopy is an extremely safe procedure, but you may feel some discomfort as the scope is carefully passed or as air is introduced to help move the scope along.

While complications may occur, the occasion is rare, and your physician can discuss this information with you with the specifics of your case in mind.

After the colonoscopy, you should plan on resting for the remaining part of the day. In some cases, patients experience bloating, gas, or cramping. These typically disappear within 24 hours.
