What Symptoms to Expect Before, During, and After a Colonoscopy

A colonoscopy is a medical procedure that allows doctors to examine the inner lining of the large intestine (colon) and rectum using a flexible tube with a camera. It is typically performed to screen for colon cancer, polyps, or other gastrointestinal issues. While it may sound intimidating, understanding the symptoms you may experience before, during, and after the procedure can help alleviate any anxiety and prepare you for the experience.

Before the Colonoscopy

Before undergoing a colonoscopy in Singapore, your doctor will provide you with instructions on how to prepare yourself. The primary preparation step involves emptying the colon, which typically requires fasting and taking a prescribed laxative or bowel-cleansing solution. This preparation is essential because it ensures that the doctor can clearly see the colon during the procedure. Here’s what you can expect:

1. Dietary Changes: You will need to follow a special diet for a few days before your colonoscopy. Typically, your doctor will recommend a low-fibre diet for a few days, followed by a clear liquid diet on the day before the procedure. Foods like broth, tea, coffee, and clear juices are typically allowed.

2. Bowel Preparation: You will be required to drink a bowel-cleansing solution that helps flush out the contents of your colon. This may cause some discomfort, such as bloating, nausea, or frequent trips to the bathroom. This step is crucial to ensure the colon is fully cleared for a successful colonoscopy.

3. Possible Anxiety or Nervousness: It’s normal to feel anxious before a colonoscopy. Fear of the unknown and concerns about discomfort are common. However, discussing these feelings with your colonoscopy doctor can help alleviate concerns. Your doctor may offer sedation options to make the procedure more comfortable.

During the Colonoscopy

On the day of the procedure, you will be asked to lie on your side or back as the colonoscopy specialist inserts the flexible tube into your rectum. The procedure typically takes between 30 minutes to an hour. Here’s what to expect during the colonoscopy:

1. Sedation or Anaesthesia: Most people undergoing a colonoscopy will be given a mild sedative to help them relax. In some cases, general anaesthesia may be used. You may feel drowsy or even fall asleep during the procedure, and you will likely not experience pain. However, you may feel some pressure or mild cramping as the tube moves through your colon.

2. Air Insufflation: To help the doctor get a better view, air will be introduced into your colon. This may cause you to feel bloated or uncomfortable during the procedure. However, the sensation typically fades once the procedure is completed.

3. Possible Biopsy or Polyp Removal: If your doctor finds any abnormal growths or polyps during the colonoscopy, they may take a biopsy or remove the polyps for further testing. This process is typically painless, as the colonoscopy specialist will use special tools that are inserted through the colonoscope.

After the Colonoscopy

After the procedure, you’ll be taken to a recovery room, where you’ll be monitored for a short period as the sedation wears off. It’s normal to feel groggy, and you may need someone to drive you home. Here’s what you can expect:

1. Mild Cramping or Bloating: After the air is released from your colon, you may experience mild bloating or cramping. This sensation typically subsides within a few hours, but it’s important to give your body time to recover.

2. Gassiness: Many people experience increased gas after a colonoscopy. The air introduced during the procedure can lead to a temporary build-up of gas in the colon, causing discomfort. Passing gas or having a bowel movement will help relieve this.

3. Minor Bleeding: It’s not uncommon to have a small amount of bleeding after a colonoscopy, especially if a polyp was removed. This may appear as blood in your stool or on the toilet paper. However, it should be very minimal and stop within a few days.

4. Fatigue: Because of the sedation, you may feel tired or lethargic for several hours after the procedure. This is normal, and you should rest until you feel fully alert.

5. Post-Colonoscopy Diet: Your doctor will advise you on when you can resume your normal diet. It is recommended to start with light, easy-to-digest foods and gradually move to your usual meals.

If you experience any of the following symptoms, you should seek immediate medical attention:

• Severe abdominal pain or bloating
• Heavy or persistent bleeding
• Vomiting
• Fever
