Frequently Asked Questions
What is a Colonoscopy?
Colonoscopy is a diagnostic procedure that uses a long, flexible tube with a camera (colonoscope) to examine the inside of the large intestine (colon) and rectum. It helps detect abnormalities in the lower digestive tract.
Why is a Colonoscopy done?
A Colonoscopy is performed to investigate symptoms such as abdominal pain, rectal bleeding, chronic diarrhea, constipation, or unexplained weight loss. It is also used for colorectal cancer screening and detecting polyps.
How should I prepare for a Colonoscopy?
Preparation usually involves following a special diet and taking prescribed laxatives to completely empty the colon before the procedure. Your doctor will provide detailed preparation instructions.
Do I need to fast before a Colonoscopy?
Yes, patients are typically advised to consume only clear liquids and avoid solid food for a specified period before the procedure to ensure proper bowel preparation.
Is Colonoscopy painful?
Colonoscopy is generally not painful because sedation is commonly given to keep you comfortable. Some mild cramping or bloating may occur after the procedure.
How long does a Colonoscopy take?
The procedure usually takes about 20 to 40 minutes. Including preparation and recovery time, you may need to stay at the facility for a few hours.
Is Colonoscopy safe?
Yes, Colonoscopy is considered safe when performed by trained specialists. Complications are rare but may include bleeding, infection, or perforation in uncommon cases.
Can polyps be removed during a Colonoscopy?
Yes, if polyps are found during the procedure, they can often be removed immediately. Tissue samples (biopsies) can also be taken for further examination.
When will I get my Colonoscopy results?
The doctor may explain the initial findings after the procedure. If biopsies are taken, laboratory results may take a few days.
Who should undergo a Colonoscopy?
Adults aged 45 and above are generally advised to undergo routine colorectal cancer screening. Individuals with symptoms or a family history of colorectal cancer may require earlier or more frequent screening as recommended by a doctor.
