The fear of the unknown is the biggest barrier that stops people from getting a colonoscopy. This is serious because colonoscopies save lives every day. In recognition of Colon Cancer Awareness Month, we’re answering the most commonly asked questions about colonoscopies to help alleviate fear. If you’re one of the fearful, hopefully this information will change your mind!
THE TEST
Q: I’m afraid I’ll feel something. Will I?
A: No. You’re given medicine to make you sleep through a colonoscopy, so you don’t feel anything.
Q: Does it hurt?
A: Most people feel nothing during or afterward. But everyone is different, so some people may feel a little discomfort.
Q: Who does the test?
A: A doctor or a surgeon.
Q: Where is it done?
A: In a hospital or a surgery center or other facility, and always in a private area. Healthcare professionals understand that privacy is very important to patients.
Q: How long does it take?
A: The actual test takes usually less than an hour. You’ll need time before to answer questions, have an IV started, and some time afterward for the medicine that makes you sleep to wear off. Probably about two hours in total.
Q: What if they find something?
A: If the doctor finds a small polyp (a small growth, typically benign and with a stalk, protruding from a mucous membrane), he or she will usually remove it during the test.
THE BOWEL PREP
Q: I’ve heard you have to drink several gallons of water as part of the prep.
A: The prep has changed over the years. Some people may still drink a lot of fluids and others may take pills. Ask you doctor what your options are and together you can determine which is best for you. The important part is to make sure your colon is as cleared out as possible so the doctor can see clearly during the test.
Q: How long will it take to complete my bowel prep?
A: Everyone is different. For some people, it can take four hours and others may take eight. You should plan to be near a bathroom during this time.
Q: If I feel cleaned out, do I have to finish the prep?
A: Yes.
OTHER PREPARATION
Q: What about eating?
A: At some point before your test, you will have to have clear liquids. This includes clear broth, apple juice, ginger ale, 7-Up, Sprite or colas, popsicles and more. You may also have black coffee or tea but no liquid or powdered creamer.
Q: Can I smoke during the prep?
A: Yes. (At OHC, we recommend you give up tobacco products completely to improve your general health and reduce your risk of cancer.)
Q: Can I have cream and sugar in my coffee?
A: Sugar or sugar substitutes, yes. Cream (liquid or powdered), no.
THE DAY OF YOUR COLONOSCOPY
Q: Why do I have to stop drinking at some point before my test?
A: If there are liquids in your stomach when given sedation, those liquids could be sucked into your lungs causing serious complications.
Q: Can I brush my teeth the morning of my procedure?
A: Yes.
Q: Can I take my antianxiety medications the morning of my procedure?
A: Yes with a small sip of water.
Q: Can I have a colonoscopy if I’m on my period?
A: Yes.
AFTER YOUR COLONOSCOPY
Q: When can I eat?
A: You can eat right away but best to avoid spicy or greasy food. Some people have some mild nausea and don’t feel like eating much until the next day.
Q: When will I have a normal bowel movement?
A: It may take a couple days since you were cleaned out for the test.
Q: When can I go back to work?
A: You can resume your usual activities the day after your test.
