Colonoscopy

What Is a Colonoscopy?

A colonoscopy is a diagnostic procedure used to examine the inner lining of the large intestine (colon) and rectum. This test is often performed to detect abnormalities such as polyps, tumors, inflammation, or bleeding, and to screen for colorectal cancer. During the procedure, a long, flexible tube with a camera (called an endoscope) is inserted through the rectum to visualize the entire colon.

When is a Colonoscopy Needed?

A colonoscopy is often recommended for both diagnostic and preventive purposes:

Routine Screening: Individuals over 45 are typically advised to undergo regular colonoscopy screenings to detect early signs of colorectal cancer or polyps.

Digestive Symptoms: If you experience persistent abdominal pain, rectal bleeding, chronic diarrhea, or unexplained weight loss, a colonoscopy may be necessary to identify the cause.

Family History of Cancer: If you have a family history of colorectal cancer or polyps, early and more frequent screenings may be advised.

Procedure Overview

A colonoscopy is usually performed as an outpatient procedure and typically takes about 30-60 minutes. The patient is sedated to ensure comfort during the examination. The colonoscope is carefully inserted into the rectum and guided through the entire colon. If polyps or abnormal tissue are found, they may be removed or biopsied during the procedure for further testing. After the colonoscopy, patients are monitored briefly while the sedation wears off.

What Happens If Issues Are Detected?

If polyps or other abnormalities are discovered during a colonoscopy, they are often removed or sampled for a biopsy. Depending on the results, follow-up procedures, additional treatments, or further monitoring may be necessary. Early detection through colonoscopy can prevent the progression of polyps into cancer.

Recovery and Results

After the procedure, patients may experience mild cramping or bloating, but these symptoms typically resolve quickly. Full recovery from sedation takes a few hours, and patients are advised to rest for the remainder of the day. Most individuals can resume normal activities by the next day. Your doctor will provide you with the results of the colonoscopy, and any tissue samples taken will be analyzed, with results typically available within a few days.
