What To Expect During a Colonoscopy?

Colonoscopy is a vital medical procedure used in the diagnosis of diseases of the lower gastrointestinal tract and in reducing the prevalence of colorectal cancer in the United States. Over 15 million Americans undergo this procedure annually, contributing to a significant 69% decline in colorectal cancer rates. Colonoscopies are performed by inserting a colonoscope, which is a flexible tube equipped with a small camera and light source, into the rectum to examine the large intestine.

While the prospect of a colonoscopy may be intimidating for some, it's a crucial step in safeguarding your gastrointestinal (GI) health. Here, we will look at what you can expect during a colonoscopy, including the screening process and how it can benefit colon and GI health.

How Is A Colonoscopy Done?

Suppose you are experiencing GI issues or are at the recommended age for routine cancer screening. In that case, your primary care physician or medical health provider may refer you to a gastroenterologist to further evaluate your digestive system. If a colonoscopy is deemed necessary, your gastroenterologist will schedule you for a colonoscopy and give you an in-depth review of all procedure steps and preparations. 

A standard colonoscopy is a non-surgical procedure typically lasting 30 minutes to an hour. Patients are sedated for the entire procedure to reduce discomfort and promote relaxation of rectal muscles. Sedation is typically accomplished through either moderate sedation with fentanyl (a pain medication), and Versed (a sedative), or by using a stronger sedative called propofol.  Fentanyl and Versed can be administered by your gastroenterologist. Propofol requires the participation of an anesthesiologist. Once fully sedated, your gastroenterologist will gently insert the colonoscope into the rectum and slowly advance it through your colon. The colonoscope’s camera transmits images of your GI system to a monitor, allowing doctors to examine images and screen for any abnormalities or instances of cancer. If an abnormality is detected, your gastroenterologist may use tools to retrieve a biopsy of abnormal tissue to be sent to the laboratory for further research. 

Why Colonoscopies Are Important

Routine colon screenings are essential for detecting colorectal cancer and removing precancerous polyps, also known as abnormal tissue growths, before they develop into cancer. Colorectal cancer often develops slowly, remaining asymptomatic in its early stages. As a result, doctors typically begin screening for colorectal cancer in patients between the ages of 45 and 75.

However, if you have increased risk factors, such as a family history of colorectal cancer and polyps, bowel diseases such as Crohn’s disease or ulcerative colitis, or other genetic syndromes or abnormalities, colonoscopies may be required more frequently or before the age of 45. 

Preparing for Your Colonoscopy

Preparing for a colonoscopy involves a complete bowel cleansing process to ensure a clear view of the colon. After your initial consultation, your gastroenterologist will give you instructions for maintaining a clear liquid diet, prescribe laxatives, and provide a pre-colonoscopy drink solution. While this preparation can be inconvenient for many, it is essential for the success of your colonoscopy. It ensures that your doctor can assess your colon health accurately. 

On the day of your colonoscopy, be sure to have all your documents, such as your insurance cards and deductibles, ready for processing. After the procedure, patients may be sleepy for several hours after waking up from sedation. Therefore, you must arrive for your procedure with a trusted friend or relative who can drive you home and look after you while you recover. If you cannot find someone to drive you, your procedure may be canceled or rescheduled. 

Recovering From a Colonoscopy

Most people experience minimal discomfort after a colonoscopy, while others experience excessive bloating or gas for a short time. After your procedure, you can expect to be held in a recovery area for an hour so that your medical team can check on your vitals and ensure that you are safe while waking up from sedation. In many cases, doctors will require the patient to pass gas following their colonoscopy to ensure that any air from the procedure is being released. 

Rest and slowly incorporating everyday foods into your diet are recommended for a successful recovery. If polyps or biopsies were taken or removed from the colon, your doctor may advise you to avoid blood thinning medication until fully recovered. 

The Benefits of a Colonoscopy

While the anticipation of a colonoscopy can often induce anxiety and dread, it is essential to remember the purpose of a colonoscopy and how early detection and screening can save your life. A few benefits of getting a colonoscopy done are:

• Early detection of colorectal cancer
• Prevention of colorectal cancer through polyp removal
• Assessment of other digestive conditions
• Peace of mind and reduced anxiety about colorectal health

Colonoscopies are painless and generally safe procedures. Considering their benefits and scheduling an appointment with a trusted specialist is a step in the right direction when it comes to leading a long, healthy, and happy life.
