What does "NPO after midnight" mean in the context of preparing for an EGD?

In the context of preparing for an EGD (esophagogastroduodenoscopy), "NPO after midnight" means that clients should avoid oral intake until the procedure. This instruction is critical to ensure that the stomach is empty, which helps to reduce the risk of aspiration during the procedure and allows for clear visualization of the upper gastrointestinal tract.

Having an empty stomach minimizes the presence of food or liquids that could obstruct the endoscope or lead to complications during sedation. It is a standard pre-procedural instruction that emphasizes the importance of fasting to enhance patient safety and the effectiveness of the examination.

Given this, patients are required to refrain from consuming any food or drink, including water, after midnight leading up to their appointment for the EGD. Other options suggest limited intake or specific allowances that would not comply with the NPO directive established for such procedures.
