What does NPO stand for?

The term NPO stands for "nothing by mouth," which is commonly used in medical settings to indicate that a patient should not consume any food or drink. This instruction may be given for various reasons, such as prior to surgery, to prepare for certain medical tests, or when patients have swallowing difficulties.

This restriction is important in clinical practice to prevent complications such as aspiration, which can occur if a patient eats or drinks when they are not supposed to. Following this guideline ensures patient safety and better management of their medical condition.
