Preparing for a Colonoscopy or EGD

Preparing for a Colonoscopy or EGD

Prior to procedure you will meet with your surgeon and he/she will explain the benefits and risks associated with the procedure. You and your surgeon will choose a day and time and will schedule this with our surgery department.
Our pre-admission teaching nurse will call you and obtain information about your medication history. This usually takes place two weeks prior to your procedure. During your visit she will gather information regarding your general health. If your surgeon has ordered any lab work, x-rays, or EKG, you will be advised when to have this done.
It is advised that you follow these recommended steps prior to any procedure:

  • Quit smoking or at least cut down before procedure
  • Stop drinking alcohol at least 24 hours before surgery
  • Advise the pre-admission nurse of any illegal drug use or herbal supplements
  • Ask your surgeon about taking any meds before surgery
  • Arrange rides to and from the hospital
  • Do not eat or drink anything after the time specified by your surgeon
  • Call your doctor if you develop a fever, cold, or rash
  • Plan for aftercare such as transportation or home care 

Day of Procedure

It is normal to feel apprehensive. Please remember that your surgeon and surgical team have done this procedure many times.
Before you leave home:

  • Shower or bathe the night before and morning of using antibacteria soap such as dial
  • No makeup, lipstick, fingernail polish, or hair products
  • Wear loose, comfortable clothing
  • Leave all valuables at home including jewelry, cash, credit card, etc. 

Be sure to bring:

  • Insurance cards or forms and photo ID
  • A list of medications and dosages you routinely take at home
  • A parent or legal guardian if under age 18 

Check in

  • Please report to the admission desk and sign any forms.
  • You will be directed to Same Day Services.
  • You will change into a hospital gown.
  • The nurse will place an identification bracelet and allergy bracelet (if necessary) on your wrist.
  • You will remove your glasses, dentures, and hearing aids if necessary.
  • An IV will be started in your arm or hand to provide medications and fluids. 


  • A nurse will take you to the Endoscopy Room.
  • You will have monitors attached that show the staff your blood pressure, heart functions, and oxygen levels. 


After surgery you will either be taken back to your room or to the recovery room and monitored closely.
It is not unusual after a Colonoscopy to pass gas. A mild sore throat may occur after EGD. Mild bruising or soreness may occur at the IV insertion site. These generally disappear in a short time.
At first you may feel unsteady on your feet. Please call for help, until the nurse says that you may get up without assistance. It is in your best interest to become active as soon as possible and gradually increase your activity.
A healthy diet will speed your recovery. It is wise to ease back to a normal diet. Eat small amounts of bland foods at first as directed by your physician.  


Your doctor determines when you will be discharged. Your nurse will go over your home instructions and send a copy with you. Be sure you undertand the instructions and ask any questions you may have at this time. Please have someone available to drive you home.
Some topics to discuss with your doctor:

  • Medications
  • Pain Control
  • Diet
  • Activity
  • Driving
  • Follow-up Appointment
  • Returning to work 

 Our staff will make every effort to contact you the day after discharge or within 72 hours to check on your progress. 

Reasons to call your surgeon:

  • A fever over 101°
  • Bleeding from your GI tract
  • Nausea, vomiting, rash or itching 


After you are home you will receive a survey in the mail. There will be questions regarding your visit with us. Please take time to complete and mail the survey. The feedback from the surveys allows us to continually work on improving our services.
