Colonoscopy
Health screening can feel a bit stressful if it’s your first time. The process may be different for everyone, depending on what is included in the screening package. It can take 3-4 hours or even a whole morning or afternoon. Here are some important guidelines to help you prepare and get the best results from your screening
Colonoscopy
Caution
- If you are taking anticoagulants (e.g., Coumadin, Warfarin), do not stop them on your own. Consult your prescribing doctor and inform the nurse in advance.
- If you have had brain or heart procedures/surgeries or are currently taking any medications, consult your doctor and notify the nurse in advance.
- Take blood pressure, heart, thyroid, anticonvulsant, or asthma medications around 5 AM on the day of the screening with a small amount of water.
- If you are taking diabetes medications, do not take insulin or diabetes pills on the morning of the screening. Instead, bring them with you.
2–3 Days
Before the screening- Avoid eating foods like greens, beans, seeds, chili powder, fruits with seeds, vegetables (e.g., kimchi), nuts, and corn.
- These foods may leave residue in your intestines, making it difficult to get a clear view during the colonoscopy and increasing the risk of missing abnormalities.
