NPO is an abbreviation derived from the Latin phrase ‘nil per os,’ which translates to ‘nothing by mouth.’ In medical settings, this term is commonly used to indicate that a patient should not consume any food or liquids orally.
The reason for placing a patient on NPO status can vary. It is often used before surgical procedures to ensure that the stomach is empty, minimizing the risk of aspiration during anesthesia. It may also be advised for certain diagnostic tests or in cases where a patient’s swallowing ability is impaired. Additionally, some medical conditions may warrant an NPO status to allow the gastrointestinal tract to rest.
Healthcare providers will typically provide specific instructions regarding how long a patient needs to be on NPO status and when they can resume eating and drinking. It’s crucial for patients to follow these guidelines to avoid complications.
