What Is a Colonoscopy? A Clear Guide from the Queens Gastro

Many patients come to my Forest Hills practice feeling unsure—or even anxious—about scheduling a colonoscopy. That’s completely normal. Our goal is is to make the process understandable, comfortable, and as stress-free as possible.

What Is a Colonoscopy?

A colonoscopy is a medical procedure that allows us to examine the colon (large intestine) and rectum using a thin, flexible tube called a colonoscope. This instrument has a camera and light at the end, which lets me view the inside of your digestive tract in real time.

Why Colonoscopies Matter: Early Detection Saves Lives

Colorectal cancer is the second leading cause of cancer death in the U.S.—yet it is one of the most preventable. A colonoscopy is the gold standard for detecting precancerous polyps, colon cancer, inflammation, diverticulosis, and unexplained bleeding.

Who Should Get a Colonoscopy?

Average-risk adults should begin screening at age 45 and continue every 10 years if results are normal. Higher-risk individuals may need earlier or more frequent screenings.

How the Procedure Works

1. Preparation (“The Prep”): Clear-liquid diet, bowel-cleansing solution, medication adjustments.

2. Day of the Procedure: Light sedation keeps you relaxed and comfortable.

3. The Colonoscopy: A 20–30 minute exam; polyps can be removed immediately.

4. Recovery: Short recovery period; someone must drive you home.

Is a Colonoscopy Painful?

Most patients do not feel or remember the procedure due to modern sedation techniques.

What Are the Risks?

Complications are rare, especially with trained specialists.

What Happens After the Results?

Normal exam: Repeat in 10 years.

Polyps removed: Follow-up depends on findings.

Abnormal results: Next steps discussed together.
