Frequently Asked Questions

What happens if I eat or drink before my procedure?


For your safety, it is critical to follow the pre-procedure fasting instructions. If you eat or drink too close to your procedure, it may be cancelled or rescheduled. Sedatives given during the procedure affect your body’s ability to keep food and liquid in your stomach, which could cause serious complications such as aspiration. Refer to your specific procedure instructions for exact fasting times.

What if I start vomiting while drinking the prep solution?


Stop the prep for about 30 minutes, then resume slowly and in small sips.

The following suggestions may help reduce nausea:

  • Use cold water or refrigerate the prep solution before drinking.
  • Drink through a straw.
  • Try mint or ginger (tea, candy, or gum).

If you cannot finish the full prep or vomiting continues, contact the office at (208) 343-6458.

How do I know when my bowel prep is complete?


After completing your bowel prep, your bowel movements should be clear or yellow liquid with no solid stool. This means your colon is adequately cleansed and ready for the procedure. Most patients continue to pass this liquid right up until the procedure itself.

I finished my prep but don’t think it worked. What should I do?


If you are still passing formed stool or dark brown fluid after finishing your prep, your procedure may need to be rescheduled. Please contact our medical staff as soon as possible at (208) 343-6458.

Can I drink alcohol the day of my bowel prep?


No. Alcohol can cause dehydration, which worsens the dehydration that commonly occurs during bowel prep. It is important to stay well hydrated with water or clear fluids instead.

Does constipation affect bowel preparation?


Yes. If you are constipated when starting prep, the prep may not work as effectively, possibly leading to poor bowel cleansing and the need to reschedule. If you do not normally have at least one bowel movement per day, call the office ahead of time at (208) 343-6458 to discuss special prep instructions.

Can I have a colonoscopy during my menstrual cycle?


Yes. Menstruation does not interfere with having a colonoscopy.

Can a family member or friend stay with me during the procedure?


No. Only patients are allowed in the procedure room. After your procedure, your physician will speak with your family member, friend, or designated contact in the recovery area.

Why can’t I drive after my procedure?


Sedation used during colonoscopies and upper endoscopies can cause grogginess and slowed reflexes for up to 12 hours. You must arrange for a responsible adult to drive you home and stay nearby if they want to hear your results. Rideshares such as Uber or Lyft are not recommended due to sedation effects.

What if I have a sore throat after an upper endoscopy (EGD)?


A sore throat after an upper endoscopy is common and can last a few days.

To ease discomfort:

  • Sip cold or warm liquids.
  • Avoid foods that can scratch your throat (for example, chips, crackers, pretzels, or nuts).
  • An over-the-counter numbing throat spray may help.
