Colonoscopy: What to Expect, Benefits, and Preparation

What is a Colonoscopy?

A colonoscopy is a test that lets doctors look inside your large intestine. During this test, a thin, flexible tube with a camera is gently inserted into your rectum. This helps doctors check for problems like polyps, bleeding, or signs of colon cancer. Many people feel nervous about colonoscopy, but it is a safe and common procedure. According to the CDC, colonoscopy is the gold standard for colon cancer screening.

Why is a Colonoscopy Performed?

Doctors use colonoscopy for several reasons. First, it helps find early signs of colon cancer. Second, it can check for causes of stomach pain or bleeding. Also, colonoscopy can remove small growths called polyps before they turn into cancer. In many cases, this test can even help prevent serious illness.

Symptoms and Signs Indicating Need for Colonoscopy

Sometimes, your doctor may suggest a colonoscopy based on certain symptoms. For example, you may need this test if you have:

Blood in your stool

Unexplained weight loss

Long-lasting stomach pain or cramps

Changes in your bowel habits

A family history of colon cancer or polyps

Additionally, people over age 45 should consider regular colonoscopy screening, as recommended by the CDC.

How to Prepare for a Colonoscopy

Proper preparation is key for a successful colonoscopy. Your doctor will give you clear instructions. However, here are some common colonoscopy preparation tips:

Follow a clear liquid diet the day before your test

Avoid red or purple drinks, as they can look like blood

Take the bowel prep medicine as directed to clean your colon

Arrange for someone to drive you home after the procedure

Tell your doctor about all medicines you take

Because a clean colon helps your doctor see clearly, it is important to follow all instructions closely.

What Happens During the Procedure?

Many people wonder what happens during colonoscopy. First, you will change into a hospital gown. Next, you will get medicine to help you relax or sleep. Then, the doctor gently inserts the colonoscope into your rectum. The camera sends pictures to a screen, so the doctor can check your colon. If needed, small polyps can be removed during the test. The whole procedure usually takes 30 to 60 minutes. Most people feel little or no pain.

Like any medical test, colonoscopy has risks and benefits. However, the benefits often outweigh the risks. Here are some key points:
