Instruction for Colonoscopy (Orafang)

Importance of Bowel Preparation

The accuracy of the examination and diagnosis depends on bowel preparation. Inadequate bowel preparation may make accurate diagnosis dicult and may require a repeat examination, resulting in additional time and cost.

Please follow the instructions for bowel preparation medication, dietary restrictions, and fluid intake carefully.

A co-payment of KRW 25,000 will be charged for re-shipment of bowel preparation medication.

Pre-examination Cautions

  1. If you are taking antiplatelet medications (e.g., Aspirin, Plavix, Pletal) or anticoagulants (e.g., Warfarin, Coumadin, Heparin) for cardiovascular or cerebrovascular disease, please consult your prescribing physician and stop taking them 5 days before the examination. However, approved medications for hypertension, thyroid disease, or heart conditions may be taken with a small amount of water early on the morning of the examination.
  2. If you are taking important medications such as heart medications (including after cardiac surgery, stent placement, or pacemaker implantation), immunosuppressants, or medications for liver cirrhosis, please consult your physician before undergoing colonoscopy.
  3. Due to the risk of hypoglycemia during fasting, do not take diabetes medication or insulin on the morning of the examination.
  4. If you are using Wegovy® or Mounjaro®, please stop taking them 7 days before the examination.
  5. If you have undergone abdominal surgery, colonoscopy is generally recommended only after at least 6 months.
    As eligibility may vary depending on the type of surgery and recovery status, please inform and consult the call center when making your appointment.
  6. If you are scheduled for sedated endoscopy, you must not drive after the examination. Please use public transportation.
  7. Nail polish or gel nails may aect oxygen saturation monitoring. Please remove them before your visit.
  8. Sedated endoscopy may be restricted for patients with a BMI of 35 or higher due to the risk of sleep apnea.
  9. If a colon polyp has been removed during the procedure, air travel is not permitted for 7 days. Alcohol, smoking, and certain foods should also be avoided during this period.

* Even when your stool is clear as water, you should take all colonoscopy laxative.

 

For accurate examination, it is very important to clean your bowel. While taking a solution, moving your body through abdominal massage or walking will help you empty the bowel rather than just lying down or sitting still.

※ Since the examination will not proceed properly if it is dicult to take a colonoscopy laxative(medicine) or your bowel is not prepared, you should take it in a timely manner as instructed. Please do not have water, gum, candy, or smoke after taking all until the examination.

※ If you cancel colonoscopy, please make sure to return the drugs you received.
