You will be provided with detailed instructions from the hospital on your digestive prep. Please review them carefully. Below is a general guidance on what to expect:
Colonoscopy Guidance
🔔 Diet: For those going through colonoscopy and upper endoscopy - you need to start a low-residue diet 2 DAYS prior to the examination. For those with constipation problems, please start low-residue diet 3 days prior. More details below.
🔔 If you have thyroid conditions, please provide detailed history to evaluate if you are eligible for endoscopies.
🔔 If you have fake nails installed, please be sure to remove it before the examination to allow for finger monitoring of biometrics during procedure.
🔔 Precautions before upper endoscopy:
(1) If you are taking hypoglycemic medication for diabetes, please stop taking the medication after you begin taking laxative the night before the examination to avoid hypoglycemia.
(2) If you are taking anticoagulant medications (such as aspirin, anticoagulants, plavix, etc.), Chinese medicine (promoting blood circulation and removing blood stasis), ginseng, and ginkgo, please stop taking them 7 days before the examination to avoid the risk of bleeding from polyp resection.
(3) If you have plans to go abroad to take a plane within 5 days after the examination, it is not recommended to have large polyp electrocautery and hemostatic clips (small polyp resection does not affect your travel plan). The incidence of small polyps is about 95%, and the incidence of large polyps is <5%.
