A colonoscopy is a diagnostic and therapeutic procedure we use to examine the entire colon, screen for colon cancer, remove polyps when seen, and investigate symptoms such as rectal bleeding or a persistent change in bowel habits.

What a colonoscopy is and who it is for

A colonoscopy is an examination of the large intestine using a flexible endoscope with a light and camera. We use it to look for polyps, tumors, inflammation, and sources of bleeding. The procedure is appropriate for people who need routine screening for colon cancer, those with symptoms like unexplained abdominal pain or anemia, and patients who require surveillance after prior polyps were found. If you want an overview of screening options and timing see our page on colon cancer screening.

Benefits of colonoscopy

  • Direct visualization of the entire colon so we can identify abnormal tissue
  • Ability to remove polyps during the same procedure which lowers future cancer risk
  • Biopsy capability to diagnose inflammation, infection, or cancer
  • Definitive investigation for unexplained bleeding, chronic diarrhea, or persistent constipation
  • Guides treatment choices by clarifying the cause of symptoms

Our colonoscopy process

We follow a clear sequence to keep the procedure safe and effective. Below we outline how we prepare, what happens the day of the procedure, and what to expect after.

  1. Pre procedure evaluation. We review your medical history, medications, allergies, and prior surgeries. This helps us choose the right sedation plan and identify any special precautions.
  2. Preparation guidance. A clean colon is essential for a complete exam. We explain the preparation steps, recommended clear diet, and timing of bowel cleansing. For detailed instructions see our colonoscopy preparation topic.
  3. Day of the procedure. You arrive at our outpatient unit. We provide monitored sedation or anesthesia per your needs. The scope is gently advanced to examine the colon while we inspect the mucosa and address findings.
  4. Treatment during the exam. If we see polyps we remove them with biopsy forceps or a snare. Tissue samples are sent to pathology when needed. Most therapeutic steps are completed during the same visit.
  5. Recovery and discharge. After the exam you recover under observation until the sedation wears off. We review findings and follow up plans before you go home. For typical recovery expectations see our post colonoscopy recovery page.

Pro tip: Accurate bowel preparation makes the difference between a complete exam and a need to repeat the procedure. Follow the preparation instructions and ask us if you have concerns about tolerating the regimen.

What good quality colonoscopy looks like

High quality work means a complete exam to the cecum, careful inspection on withdrawal, appropriate polyp removal, and clear documentation for follow up. We record findings with still images, describe polyp size and location, and recommend surveillance intervals that match current guidelines. When complex polyp removal is required we discuss referral options and the risks and benefits before proceeding.

Frequently asked questions

Frequently asked questions

How long does a colonoscopy take and how long am I in the clinic?

The procedure itself typically takes 20 to 40 minutes. Allow additional time for check in and recovery which often totals two to three hours. Exact timing varies with sedation choice and any treatments performed during the exam.

Will I be asleep for the colonoscopy?

Most patients receive monitored sedation so they are comfortable and drowsy. Some patients may receive deeper anesthesia depending on health factors and preference. We discuss options during the pre procedure evaluation.

Can polyps be removed during the same colonoscopy?

Yes. When safe to do so we remove polyps during the same visit. Tissue samples are sent to pathology to determine whether further treatment is needed. For more about finding and removing polyps see our topic on polyp detection and removal.

How should I prepare and what can I eat before the test?

Preparation usually includes a clear diet the day before and a bowel cleansing regimen. Specific instructions depend on medications and health conditions. Review our colonoscopy preparation topic for step by step guidance and call our office with questions before the day of the test.

What are the risks of colonoscopy?

Colonoscopy is generally safe but has small risks, including bleeding after polyp removal and, rarely, perforation. Sedation has its own risks which we minimize with careful monitoring. For a balanced discussion see our colonoscopy risks and benefits resource.

Before your visit

  • Read the preparation instructions on our colonoscopy preparation topic
  • Bring a list of current medications and allergies
  • Arrange for a responsible adult to accompany you home after sedation

Frequently asked questions

When should I start screening for colon cancer?

Screening recommendations vary with age, family history, and prior findings. Many people begin screening at age 45 or earlier with personal or family risk factors. Our colon cancer screening topic explains the options and intervals for different risk levels.

Will I need someone to drive me home?

Yes. Because sedation impairs reaction time and judgment you must have a responsible adult drive you home and remain available for the first 24 hours.

How soon will I get results?

We review immediate findings before discharge. If biopsies or polyp pathology are sent, results typically return in several days to a week. We will communicate a clear plan for follow up based on those results.
