Colonoscopy
Importance of Colonoscopy Screening
Exeter Hospital offers colonoscopy to detect and prevent problems in the colon and rectum. This test allows doctors to look for inflammation, ulcers, polyps, and other growths.
Colonoscopy is also the most effective way to find early signs of colorectal cancer. It may be recommended if you are experiencing symptoms such as changes in bowel habits, abdominal pain, rectal bleeding, or unexplained weight loss.

Colonoscopy: What You Need To Know
Wondering what to expect before, during, and after a colonoscopy? The information below explains how to prepare, what happens during the test, and what recovery is like.
Before a colonoscopy, it’s important to prepare so the doctor has a clear view of your colon. Here’s what to expect:
- You'll follow a clear liquid diet for 1–3 days before your exam.
- A sedative, and sometimes pain medication, helps keep you relaxed during the procedure.
- Because of the sedative, you won't be able to drive for 24 hours after your appointment.
The colon and rectum are two connected parts of the large intestine. They work together to absorb water, form stool, and move waste out of the body:
- Colon: Absorbs water and forms stool as waste passes through.
- Rectum: The final 6 inches of the large intestine that connects the colon to the anus. Muscles and nerves in the rectum and anus control bowel movements.
Most people should begin routine colonoscopy screenings at age 50. You may need to start earlier if you have:
- A family history of colorectal cancer
- A personal history of inflammatory bowel disease
- Other risk factors — your doctor can recommend the best plan
A colonoscopy is a safe, routine test performed by a trained doctor and care team. During the procedure:
- You'll lie on your side while the doctor gently guides a flexible, lighted tube (colonoscope) through the rectum and colon.
- The scope has a camera that shows a video image of your colon lining.
- The exam usually takes 30–60 minutes. You'll be monitored throughout to ensure comfort and safety.
Colonoscopy doesn’t just find problems — it can also treat them right away. During the test:
- Polyps (growths) can be removed to prevent them from becoming cancerous.
- The doctor may also take tissue samples (biopsies) for testing.
- Both procedures are typically painless, and any bleeding can be controlled during the exam.
After a colonoscopy, most patients feel well and return to normal activity within a day. Common parts of recovery include:
- Staying at the clinic for 1–2 hours until the sedative wears off.
- Mild cramping or bloating is common, but usually fades within a few hours.
- Returning to normal activities by the next day.
Call your doctor immediately if you experience severe abdominal pain, fever, bloody stools, dizziness, or weakness.
