What is a Colonoscopy?
A colonoscopy is a widely used diagnostic and therapeutic procedure in which a long, flexible tube with a camera (colonoscope) is inserted through the rectum to inspect the entire colon. It enables doctors to detect abnormalities such as polyps, inflammation, tumors, or ulcers. Colonoscopy is considered the gold standard for colon cancer screening because it not only identifies suspicious growths but also allows for their removal during the same procedure. It is commonly recommended for patients with unexplained gastrointestinal symptoms, family history of colon cancer, or positive stool tests.
This procedure helps to:
- Detect and remove colon polyps.
- Screen for colorectal cancer.
- Investigate causes of rectal bleeding.
- Diagnose inflammatory bowel disease.
- Evaluate unexplained abdominal pain or chronic diarrhea.
What to expect after a Colonoscopy?
Preparation for colonoscopy typically involves dietary restrictions and a bowel-cleansing solution to clear the colon. Sedation is administered for comfort during the procedure. Afterward, patients may feel bloated or gassy due to air introduced into the colon, but recovery is usually quick.
- Sedation makes the procedure comfortable.
- Temporary bloating or cramping after completion.
- Return to light activities the same day.
- Results are often discussed immediately.
- A responsible adult should accompany patients home.
