What is a Colonoscopy
A colonoscopy is a diagnostic procedure used to examine the inner lining of the large intestine (colon) and rectum using a long, flexible tube called a colonoscope. Equipped with a tiny camera and light source, the colonoscope allows the gastroenterologist to visualize the entire colon, identify abnormalities, and perform biopsies or remove polyps if necessary.
Why is Colonoscopy Recommended? Best Gastroenterologist in Rohini.
Colonoscopy is primarily recommended for colorectal cancer screening and prevention. Colorectal cancer often develops from precancerous growths called polyps, which can be detected and removed during a colonoscopy before they have the chance to become cancerous. Additionally, colonoscopy can detect early-stage colorectal cancer when it is most treatable, leading to better outcomes and higher survival rates.
In addition to screening for colorectal cancer, colonoscopy may be recommended for investigating symptoms such as rectal bleeding, changes in bowel habits, abdominal pain, and unexplained weight loss. It can help diagnose conditions such as inflammatory bowel disease (IBD), Crohn’s disease, ulcerative colitis, and colorectal polyps or tumors.Best Gastroenterologist in Rohini.
Preparing for a Colonoscopy
Proper preparation is essential for a successful colonoscopy. Your healthcare provider will provide detailed instructions on how to prepare, which typically involves a clear liquid diet for 1-3 days before the procedure and taking laxatives or bowel-cleansing agents to empty the colon.
During the Procedure
On the day of the colonoscopy, you will be given sedatives and pain medications to ensure comfort and relaxation during the procedure. The colonoscope is gently inserted into the rectum and guided through the colon while the gastroenterologist carefully examines the lining for abnormalities. If polyps are found, they may be removed or biopsied for further evaluation.
After the Procedure: Following the colonoscopy, you will be monitored in a recovery area until the sedatives wear off. You may experience some bloating, gas, or mild discomfort, but these symptoms typically resolve within a few hours. It is essential to arrange for someone to drive you home after the procedure, as the sedatives can impair your ability to drive safely.
Role in Prevention and Early Detection
Colonoscopy is considered the gold standard for colorectal cancer screening due to its ability to detect and prevent the disease at an early stage. By identifying and removing precancerous polyps during the procedure, colonoscopy significantly reduces the risk of developing colorectal cancer and saves lives.
Routine screening with colonoscopy is recommended for average-risk individuals starting at age 45 or earlier if there are risk factors such as a family history of colorectal cancer or certain genetic conditions. Depending on the findings, follow-up colonoscopies may be recommended every 5-10 years.
