Can I eat eggs the day before having a gastroscopy or colonoscopy?

Generally, it is acceptable to eat eggs the day before undergoing a gastrointestinal endoscopy, but it's important to consume them in moderation, choose light and easily digestible cooking methods, and pay attention to dietary combinations. Additionally, you must follow your doctor’s instructions and properly prepare for the examination. Here is a detailed explanation:

Eggs are a nutritious food rich in high-quality protein and various trace elements. Eating a moderate amount can provide essential nutrients to the body. However, excessive consumption may lead to indigestion and increase the burden on the gastrointestinal tract, so it is recommended to eat eggs in moderation and avoid overeating.

The day before the endoscopy, it is advisable to use light and easily digestible cooking methods such as boiling or steaming (e.g., boiled eggs or steamed egg custard). Avoid oily cooking methods like frying or stir-frying, which may加重 the burden on the digestive system and affect the examination results. In addition to eggs, other light and easily digestible foods such as plain rice porridge, noodles, and tofu can also be included in the diet.

It is important to note that fasting should begin 8–12 hours before the procedure to ensure an empty stomach for better visualization during the exam. For colonoscopy, fasting typically starts after 10 p.m. the night before, along with proper bowel preparation. Drinking fluids should be stopped 2–4 hours prior to the examination to reduce gastric fluid and prevent interference. Smoking and alcohol consumption should also be avoided before the procedure, as they may irritate the gastrointestinal tract and affect the results.
