Colonoscopy

Overview

A colonoscopy is an examination of the part of your large intestine. This procedure is considered safe and offers valuable information that may not be obtained through other tests. A colonoscopy is a procedure where a flexible tube (colonoscope) is used to check the inside of your colon (large intestine) for issues like polyps or cancer. The procedure typically lasts 20 minutes to 1 hour.

Why is it done?

A colonoscopy is commonly done to:

• Screen for colon polyps/ ulcer/ growth.
• To do biopsy from the site of ulcer/ polyp/ growth.
• Investigate rectal bleeding.
• Look into changes in bowel habits (like diarrhea).
• Find causes of iron deficiency anemia (low hemoglobin).
• Follow up on abnormal results from other tests (e.g., CT scans or barium enemas).

How to Prepare for a Colonoscopy:

Preparation is important for the test to be accurate. Here's what to expect:

• Avoid solid foods for at least 1 day before the procedure.
• Drink clear liquids (water, broth, tea, etc.) the day before, but avoid red-colored liquids.
• Avoid high-fiber foods (seeds, nuts) the week before.
• Take a laxative preparation to clean out your bowel, usually in two doses (one night before, the other several hours before the procedure).
  • If you feel nauseous or vomit while drinking the prep solution, contact your doctor.
• If you take medications (especially for diabetes or blood thinning), ask your doctor if you need to adjust them before the procedure.
• Transportation: Since you'll be sedated, arrange for someone to drive you home after the procedure.

What to Expect During the Colonoscopy:

• Before the procedure, the doctor will review the process and potential risks with you and ask you to sign a consent form. An IV line will be inserted to monitor vital signs (blood pressure, heart rate, and breathing).
• Sedation:After anesthesia assessment the decision whether to given sedation will be taken by the anesthetist. If fit you'll be given sedation through an IV to keep you relaxed and pain-free.
• The colonoscope is inserted into your colon to check for problems, and air is used to inflate the colon.You may experience bloating, cramps, or a sensation of needing to use the bathroom, but these are normal.
• The doctor may remove polyps or take biopsies (which are usually painless).

Recovery after a Colonoscopy:

• After the procedure, you'll be monitored for 30-60 minutes until the sedation wears off.
• Expect some bloating and gas cramps, which should ease by passing gas.
• You might feel sleepy from the sedative, so avoid driving and working on the day of the procedure.
• Resume eating when your doctor says it's safe. If you take blood thinners, ask your doctor when to restart them.

Potential Risks and Complications:

While rare, complications can happen. If you experience any of the following, seek immediate medical help:

• Severe abdominal pain (beyond normal bloating or cramps)
• Firm, bloated abdomen (a sign of something more serious)
• Vomiting or fever
• Significant rectal bleeding (more than just spotting)

Post-Colonoscopy Care:

• Most people feel fine afterward, but some may feel fatigued. Rest the rest of the day.
• Your doctor will usually discuss the results right after the procedure, but if biopsies or polyps were removed, you need to contact your doctor with results within 3-5 days after the procedure.

Points to Remember and Critical Signs to Report Immediately:

• Before the procedure: Follow preparation instructions carefully. If you feel sick or vomit while drinking the prep solution, contact your doctor.
• After the procedure:
  • If you have severe abdominal pain, vomiting, or fever, call your doctor immediately.
  • Severe rectal bleeding (more than a small amount) should be reported right away.
• Post-procedure: Rest the day of the procedure, avoid driving or working, and check with your doctor about when to resume regular activities and medications.
