How is 'prognosis' defined in medical contexts?

In medical contexts, prognosis refers to the prediction of the probable course and expected outcome of a disease. This involves evaluating the severity and progression of the illness based on clinical data, the patient's health condition, and relevant medical history. Healthcare professionals use this information to inform patients about what might happen in the future regarding their health, including the likelihood of recovery, potential complications, or the necessity for further treatment. This understanding is crucial for both patients and healthcare providers to make informed decisions regarding management and care options. The focus on probable outcomes helps in setting realistic expectations and preparing for various scenarios concerning the disease's trajectory.
