Introduction
Digestive symptoms such as abdominal pain, blood in stools, long-standing constipation, or sudden changes in bowel habits should never be ignored. One of the most accurate diagnostic tests used to evaluate these symptoms is colonoscopy.
Colonoscopy is a safe and effective procedure used to examine the large intestine (colon). It helps in early diagnosis of serious conditions like colon polyps and colon cancer, which can be life-saving when detected early.
What is a colonoscopy?
Colonoscopy is a diagnostic procedure in which a thin, flexible tube with a camera (colonoscope) is inserted through the rectum to examine the inner lining of the colon.
The camera transmits clear images to a screen, allowing the doctor to detect:
-
Inflammation
-
Ulcers
-
Polyps
-
Bleeding points
-
Abnormal growths
This makes colonoscopy the gold-standard test for colon evaluation.
Why Is Colonoscopy Done?
Dr. Kiran KJ may advise a colonoscopy test for the following reasons:
-
Persistent abdominal pain
-
Blood in stools
-
Chronic diarrhea or constipation
-
Unexplained anemia
-
Sudden weight loss
-
Change in bowel habits
-
Family history of colon cancer
-
Routine colon cancer screening (age >45–50 years)
👉 Early colonoscopy helps prevent complications and improves long-term outcomes.
Conditions Diagnosed Using Colonoscopy
A colonoscopy helps diagnose and manage:
-
Colon polyps (pre-cancerous growths)
-
Colorectal cancer
-
Inflammatory bowel disease (IBD)
-
Ulcerative colitis
-
Crohn’s disease
-
Diverticulosis
-
Hemorrhoids
-
Colon infections and ulcers
In many cases, polyps can be removed during the same colonoscopy, preventing colon cancer before it develops.
Is Colonoscopy Painful?
One of the most common patient concerns is pain.
✅ Colonoscopy is usually painless because:
-
Sedation is given
-
Patients remain relaxed
-
Most do not remember the procedure
Mild bloating after the test is common but temporary.
Colonoscopy Preparation
Proper preparation ensures accurate results.
Preparation usually includes:
-
Liquid diet one day before the procedure
-
Bowel-cleansing medication to empty the colon
-
Temporary medication adjustments (as advised)
What Happens During a Colonoscopy Procedure?
-
Patient lies comfortably on the examination table
-
Sedation is administered
-
Colonoscope is gently inserted
-
Colon is carefully examined
-
Biopsy or polyp removal if required
⏱️ The procedure usually takes 20–30 minutes.
Recovery After Colonoscopy
-
Same-day discharge
-
Resume normal diet as advised
-
Mild gas or bloating may occur
-
Results explained clearly
Most patients return to normal activity within 24 hours.
Benefits of Colonoscopy
-
Early detection of colon cancer
-
Prevention through polyp removal
-
Accurate diagnosis of bowel diseases
-
Safe, reliable, and minimally invasive
Colonoscopy saves lives when done at the right time.
When Should You Not Delay a Colonoscopy?
Consult immediately if you experience:
-
Blood in stools
-
Severe abdominal pain
