NPO (Nil Per Os)

NPO is a Latin medical abbreviation meaning 'nil per os,' which translates to 'nothing by mouth.' When your veterinarian instructs you that your pet must be NPO, it means they should not be given any food, water, or oral medications for a specified period. This directive is common before surgical procedures, certain diagnostic tests like endoscopy, or in cases of severe vomiting or pancreatitis. Fasting helps prevent complications like aspiration pneumonia during anesthesia or allows the digestive system to rest and recover. It is crucial to strictly follow NPO instructions to ensure your pet's safety and the success of medical procedures or treatments.
