What is Colonoscopy

A colonoscopy is a medical procedure used to examine the inside of the colon (large intestine) and rectum. The exam is performed using a flexible, lighted tube called a colonoscope, which is inserted into the rectum and advanced through the colon. The colonoscope has a small camera on the end, which allows the doctor to view the inside of the colon and detect any abnormalities, such as polyps, ulcerations, or tumours.

How to prepare for a colonoscopy

Preparation for a colonoscopy is a crucial step to ensure an accurate and comfortable exam. Here are some steps you can take to prepare for a colonoscopy:

  • Follow a clear liquid diet: You will be asked to follow a clear liquid diet for one to three days prior to the exam. This helps to clear out your colon, making it easier for the doctor to examine.
  • Use a bowel-cleansing solution: You will also be asked to take a bowel-cleansing solution, such as a laxative, to completely clear out your colon. Your doctor will give you specific instructions on which solution to use and how to take it.
  • Stop taking certain medications: If you are taking any blood thinners, such as warfarin or aspirin, you may be asked to stop taking them several days prior to the exam. Your doctor will give you specific instructions based on your individual needs.
  • Avoid solid foods: Avoid solid foods for the day or two before the exam, and only consume clear liquids such as water, clear broth, apple juice, and tea or coffee without milk.
  • Arrange for transportation: You will not be able to drive after the exam because of the sedation. Make arrangements for a family member or friend to drive you home or use public transportation.
  • Bring a list of your medications: Make sure to bring a list of all the medications you are taking, including prescription, over the counter, and herbal supplements.

By following these steps, you can help ensure a smooth and successful colonoscopy. It is also important to follow any additional instructions given to you by your doctor.

After the colonoscopy

After a colonoscopy, you will need to rest and recover for a short time until the effects of the sedation have worn off. Here are some things you can expect after a colonoscopy:

  • Recovery time: You may need to rest for a few hours after the exam, depending on the amount of sedation you received. You should arrange for someone to drive you home or use public transportation.
  • Resuming normal activities: You can usually return to your normal activities the next day unless your doctor gives you specific instructions otherwise. It is important to drink plenty of fluids and eat a light diet for the first day or two after the exam to help your body recover.
  • Discomfort: You may experience some bloating, cramping, or gas after the exam, but these symptoms should go away on their own within a few hours. If you experience severe pain or discomfort, be sure to contact your doctor.
  • Results: Your doctor will discuss the results of the colonoscopy with you, usually within a few days of the exam. The results will include information on any polyps, ulcerations, or tumours found, and what, if any, further treatment is needed.
  • Prevention: A colonoscopy is also an opportunity for prevention, as any polyps found during the exam can be removed before they have a chance to develop into cancer.

Overall, a colonoscopy is a safe and effective diagnostic tool that can help detect colon cancer and other colon and rectal problems at an early stage when they are more treatable. By following your doctor’s instructions and taking care of yourself after the exam, you can ensure a smooth and stress-free recovery.

Risks associated with colonoscopy

Like any medical procedure, colonoscopy does carry some risks. However, these risks are generally rare and minor. Here are some of the potential risks associated with colonoscopy:

  • Bleeding: In rare cases, a colonoscopy can cause a small amount of bleeding, usually from a biopsy site or from the removal of a polyp. This bleeding usually stops on its own, but in severe cases, a blood transfusion may be required.
  • Perforation: There is a small risk that the colonoscope may perforate (tear) the colon wall during the exam. This can lead to abdominal pain and require surgery to repair the tear.
  • Infection: Although rare, infection can occur after a colonoscopy. Symptoms of infection include fever, abdominal pain, and discomfort.
  • Adverse reactions to sedation: Some people may experience adverse reactions to the sedatives used during the exam, such as difficulty breathing, hives, or anaphylaxis.
  • Discomfort: Some people may experience discomfort during the exam, such as bloating, cramping, or gas. These symptoms are usually mild and go away within a few hours.

Overall, the benefits of a colonoscopy, such as early detection and treatment of colon cancer, outweigh the risks. Your doctor can discuss the specific risks and benefits of colonoscopy with you, based on your individual health history and needs.
