What is typically the required fasting period before an upper endoscopy?

• A. 4 hours
• B. 8 hours
• C. 12 hours
• D. 24 hours

Answer: (B)

The required fasting period before an upper endoscopy is typically 8 hours. This fasting duration is essential to ensure that the stomach is empty during the procedure, which helps reduce the risk of aspiration and allows for better visualization of the upper gastrointestinal tract. An empty stomach also minimizes the likelihood of interference from food or liquid in the esophagus or stomach, which can hinder the endoscopist's ability to perform a thorough examination. While different practices might have variations in guidelines, 8 hours is widely accepted as standard, as it balances adequate safety measures with practicality for patients. Other fasting periods, such as 4 hours, might be sufficient in some cases, particularly for clear liquids, but a longer period is generally safer for solid food. Meanwhile, fasting periods of 12 or 24 hours are typically excessive and not necessary for an upper endoscopy. They could potentially lead to increased discomfort and complications for patients without providing additional safety benefits.
