Tag: Nil by mouth

The American Society of Anesthesiologists (ASA) has established clear fasting guidelines to minimize health risks during procedures. A common but critical query from patients is, "*Can I smoke if I'm nil by mouth?*" The unambiguous medical advice is to abstain from all tobacco and nicotine products during the specified fasting period.

According to a 2024 survey of intensive care professionals, 97% reported witnessing patient discomfort or distress when NBM. When healthcare professionals use the abbreviation NBM, they are referring to "nil by mouth," a critical patient care and pharmacology instruction. This directive prohibits any oral intake—including food, fluids, and medications—and is essential for patient safety during a variety of medical procedures.
