Prognosis vs. Diagnosis: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Prognosis is a prediction about the course and outcome of a disease. Diagnosis is the identification of the nature of an illness or other problem.
Key Differences
A prognosis is a medical term used to describe the likely outcome or course of a disease or condition over time. It is a prediction based on various factors, including the type of disease, the patient's overall health, and response to treatment. A diagnosis, on the other hand, is the process of identifying a disease or condition based on symptoms, tests, and examinations. It's about determining what the problem is.

Prognosis often involves predicting the future health status of a patient, considering the progression of their condition. It can include expected recovery time, chances of recurrence, and potential complications. Diagnosis is the first step in treating a patient, involving an assessment and conclusion about the patient's current health issue.

The prognosis is significant for understanding the long-term impact and management of a disease, providing patients and caregivers with crucial information about what to expect. In contrast, diagnosis is critical for starting the appropriate treatment and management plan, guiding healthcare professionals on how to approach the condition.

While the prognosis is forward-looking, focusing on future health outcomes, diagnosis is about the present state, identifying and naming the health challenge being faced. Prognosis can change over time with treatment and other health interventions, whereas diagnosis is typically established based on the condition at a specific point in time.
