What does the term Ad lib indicate in medical guidance?

The term "Ad lib" is derived from Latin, meaning "at one's pleasure" or "as desired." In medical guidance, it indicates that a patient can have or do something freely, according to their own personal preference and comfort level, without specific restrictions. This term is often used in contexts like dietary choices where a patient can eat food "ad lib," meaning they can select what and how much they want to consume, provided it is safe for their condition. Understanding this term is important as it empowers patients to engage in their care actively while indicating that their choices should be respected within a clinical framework.
