Colonoscopy

A colonoscopy is a medical procedure that allows specialists to examine the inside of the colon and rectum using a flexible tube equipped with a high-definition camera called a colonoscope.

This procedure helps diagnose gastrointestinal conditions, identify the cause of digestive symptoms, and detect precancerous lesions before they develop into colon cancer.

In addition to examining the lining of the colon, specialists can obtain tissue samples (biopsies) and remove polyps during the procedure.

When Is a Colonoscopy Recommended?
Your Gastroenterologist or General Surgeon may recommend a colonoscopy to:

• Investigate rectal bleeding.
  
• Evaluate persistent abdominal pain.
  
• Assess changes in bowel habits.
  
• Determine the cause of chronic diarrhea or constipation.
  
• Detect colon polyps.
  
• Diagnose inflammatory bowel disease.
  
• Screen for and help prevent colorectal cancer.

Colonoscopy is also recommended as a screening test for adults aged 45 and older and for individuals with a family history of colorectal cancer.

How Is a Colonoscopy Performed?
During the procedure, the specialist carefully inserts a colonoscope through the rectum to examine the inside of the colon.

Images are transmitted in real time to a monitor, allowing the physician to identify inflammation, polyps, bleeding, tumors, and other abnormalities.
If necessary, biopsies can be taken and polyps can be removed during the same procedure.

How Should I Prepare for a Colonoscopy?
Proper preparation is essential for accurate results.

Preparation generally includes:

• Following a special diet.
  
• Avoiding certain foods and beverages.
  
• Taking prescribed bowel-cleansing medications.
  
• Fasting before the procedure.

Following all preparation instructions carefully helps ensure a successful examination.

Before the Colonoscopy
Before the procedure, your specialist will review your medical history, family history, symptoms, and current medications.

You will also receive detailed instructions regarding bowel preparation and procedural expectations.

During the Colonoscopy
A colonoscopy typically takes between 30 and 60 minutes.

Sedation is commonly administered to maximize comfort during the procedure.

While examining the colon, the specialist can identify abnormalities, perform biopsies, and remove polyps if necessary.

After the Colonoscopy
Following the procedure, you will remain under observation while the effects of sedation wear off.

Mild temporary symptoms may include:

• Abdominal bloating.
  
• Gas.
  
• Mild cramping.

Most patients return home the same day.

Why Does Colonoscopy Help Prevent Colon Cancer?
Colonoscopy is considered the most effective method for early detection of colorectal cancer.
The procedure allows specialists to identify and remove precancerous polyps before they become cancerous, significantly reducing future cancer risk.

When colon cancer is detected early, treatment outcomes are generally much more successful.

Am I a Candidate for a Colonoscopy?
A colonoscopy may be recommended if you have persistent digestive symptoms or are seeking preventive screening.

It is particularly recommended for:

• Adults aged 45 and older.
  
• Individuals with a family history of colorectal cancer.
  
• Patients with a history of colon polyps.
  
• Individuals experiencing persistent gastrointestinal symptoms.

A specialist can determine the appropriate timing for your screening.
