Prognosis refers to the likely outcome or course of a disease or medical condition. It is an estimate made by healthcare professionals based on various factors, including the patient's health history, the nature of the illness, and available treatment options. A prognosis can help patients and their families understand what to expect and make informed decisions about care. In addition to medical contexts, prognosis can also apply to other fields, such as economics or sports, where it predicts future trends or performance. Understanding prognosis is essential for planning and preparing for potential challenges or changes in circumstances.
