"N.p.o." is a medical term that stands for "nil per os", which is Latin for "nothing by mouth". It is a directive given to patients to refrain from eating or drinking anything for a certain period of time, usually before a surgery or a medical test. This is to ensure that the stomach is empty to prevent complications during procedures. It can also be used when a patient has a medical condition that requires the stomach to be empty.
