What is a Colonoscopy?

A colonoscopy is a safe, outpatient procedure used to examine the lining of your large intestine (colon) and rectum.

During the procedure, your surgeon uses a long, flexible, lighted tube equipped with a high-definition video camera (a colonoscope). This scope transmits real-time images of your digestive tract to an external monitor, allowing your doctor to identify and evaluate abnormalities, such as:

Precancerous Polyps: Small growths on the colon lining that can be safely removed before turning into cancer.

Inflammation & Ulcers: Common indicators of conditions like Inflammatory Bowel Disease (IBD).
Unexplained Bleeding: Locating tissue irritation or vascular issues in the lower GI tract.
Digestive Changes: Investigating chronic abdominal pain, changes in bowel habits, or persistent diarrhea.

A colonoscopy is a key component of our comprehensive endoscopy services, which also include upper endoscopy (EGD) for upper gastrointestinal issues and PEG tube placement for nutritional support.

Who Needs a Colonoscopy?

1. Routine Screening (Age 45+)

The American Cancer Society and the U.S. Preventive Services Task Force recommend that adults at average risk begin regular colorectal cancer screening at age 45. If your results are normal, you typically only need a screening once every 10 years.

2. Early or High-Risk Screening

You may need earlier or more frequent colonoscopies if you have:

A personal or family history of colorectal polyps or colon cancer.
A history of Inflammatory Bowel Disease (Crohn’s disease or Ulcerative Colitis).
A known genetic syndrome associated with colorectal cancer (such as Lynch syndrome).

3. Diagnostic Evaluation

Your primary care physician or specialist may recommend a diagnostic colonoscopy if you experience warning symptoms, such as:

Blood in your stool or rectal bleeding.
Unexplained changes in bowel habits (chronic diarrhea or constipation).
Persistent abdominal cramping or chronic abdominal pain.
Unexplained iron-deficiency anemia or sudden weight loss.

What to Expect: Before, During, and After a Colonoscopy

1. Before: Preparing Your Colon

Proper bowel preparation is essential for a thorough exam. A clean colon ensures your surgeon can clearly see the intestinal lining and detect even tiny polyps.

The Day Before: You will transition to a clear liquid diet (water, clear broths, apple juice, gelatin).
Bowel Prep Solution: You will drink a prescribed laxative solution to empty your colon completely. Detailed step-by-step instructions will be provided prior to your appointment.

2. During: The Procedure

Comfort & Sedation: Before the exam begins, you will receive sedation to ensure you remain completely relaxed, comfortable, and pain-free.
The Examination: You will lie comfortably on your side while your surgeon gently guides the colonoscope through the rectum. Air or carbon dioxide is introduced to expand the colon for optimal visibility.
Polyp Removal & Biopsies: If polyps or abnormal tissues are found, your surgeon can painlessly remove them (polypectomy) or collect small tissue samples (biopsies) during the procedure.
Duration: The procedure typically takes 30 to 60 minutes.

3. After: Recovery & Results

Post-Procedure Rest: You will spend about 30 to 60 minutes in our recovery area as the sedative wears off.
Going Home: Because of the sedative, you must have a responsible adult drive you home.
Same-Day Recovery: Most patients return to light activities and a normal diet later that day. Mild gas or bloating is normal for a few hours following the procedure.
Results: Your surgeon will discuss initial findings before you leave. If biopsies or polyps were taken, pathology lab results are usually available within a few days.

Colonoscopy FAQs

Do I need another colonoscopy if my results are negative?

A negative colonoscopy result means no polyps, tissue abnormalities, or signs of disease were found. If you are at average risk for colorectal cancer, your doctor will generally recommend scheduling your next routine colonoscopy in 10 years. However, if you have a personal or family history of polyps, colorectal cancer, or specific gastrointestinal symptoms, your surgeon may recommend a follow-up examination sooner—typically in 3 to 5 years.

What happens if the doctor finds polyps during a colonoscopy?

If polyps (small growths on the colon wall) are identified during your examination, your surgeon will remove them immediately during the procedure using specialized tools passed through the scope. Polyp removal is entirely painless. The removed tissue is sent to a pathology lab for evaluation to confirm whether it is benign or precancerous. Based on the size, quantity, and cellular characteristics of the polyps, your surgeon will outline a personalized schedule for your next colonoscopy.

What are the benefits of a colonoscopy?

Colorectal cancer is the third most common cancer diagnosed in both men and women in the United States, but it is also highly preventable. The primary benefits of a colonoscopy include:

Early Detection: Identifies colorectal cancer in its earliest, most treatable stages before noticeable symptoms develop.
Active Prevention: Enables your surgeon to locate and remove precancerous polyps during the procedure before they have the chance to develop into cancer.
Diagnostic Accuracy: Helps pinpoint the root cause of unexplained gastrointestinal symptoms, such as rectal bleeding, persistent abdominal pain, or bowel habit changes.

Does a colonoscopy hurt?

No. Before your procedure begins, you will receive intravenous sedation administered by our medical team to ensure you remain comfortable, relaxed, and pain-free. Most patients fall asleep during the procedure and have no memory of the exam.

Can I drive myself home after a colonoscopy?

No. Because the sedatives used during the procedure can temporarily impair your reflexes and judgment, safety regulations require that a responsible adult driver accompany you home. You will be able to resume driving and normal daily activities the following day.
