Endoscopic Ultrasound (EUS) Preparation

Please Note:

  • If you are a diabetic hold your oral diabetic medication the morning of the procedure. Check your blood sugar the morning of the procedure. If you use insulin or an insulin pump, check with your primary care doctor for instructions during your prep and the day of your procedure. Please bring your insulin with you the day of your procedure. Drink clear fruit juice if your blood sugar gets low.
  • If you are on a medication to thin your blood (an anticoagulant or antiplatelet) do not stop your blood thinning medications until you hear from our office. We will contact your physician who prescribes this medication for instructions and notify you. If you have not heard from us a week before your procedure please call our office at 320-5050 to speak with your physician's Medical Assistant.
  • If you are on aspirin or NSAIDs you may continue to these medications.
  • If you have asthma bring your inhaler with you to your procedure.
  • If you have sleep apnea and use a CPAP machine please bring it with you to your procedure.
