Question

How do I know if I have a disease?

Answer 1

Hint: A disease is a specific abnormal condition that harms the structure or function of all or part of an organism and is not caused by an immediate external injury.

Complete answer:
Diseases are disorders that cause pain in a specific area of the body or throughout the body. This unease can be caused by a variety of factors. This is manifested by certain signs known as symptoms. Symptoms assist physicians in accurately determining diseases and, as a result, prescribing the appropriate treatment or course of action.
Diagnosis of a disease
Diagnosis is the process of studying a person's symptoms as a result of a disease. A physical examination or a brief review of the patient's medical history can be used to make the diagnosis. In some cases, tests are performed to determine the underlying cause of a disease. The diagnosis aids in categorizing a medical condition, allowing easy prognosis and treatment. Medical diagnostic procedures are performed by health care professionals to recommend treatment as well as prevent the recurrence of the same disease shortly.
The identification of a medical indication is one of the first steps in carrying out a diagnostic procedure. Any deviation from the normal state in a patient is first identified.
It is usually done by gauging and comparing the patient's current condition to what is considered normalcy, which aids in analyzing and quantifying the indication of a medical condition.
A patient's gait is another indication to doctors that communicates about discomfort and thus summons for diagnosis.

Note:
During an ongoing diagnosis, it is possible to perform another diagnostic procedure associated with another condition, which is often referred to as an incidental finding of a symptom that is not related to the condition being tested for at the time. Blood tests, if present, usually aid in the diagnosis of more than one medical condition (Anaemia, Thrombocytopenia).
