Correct Answer - Option 2 : Signs and symptoms of the disease

The correct answer is Signs and symptoms of the disease.

  • Diseases are disorders that cause one to develop discomfort in a specific region or throughout the body.
  • This sense of uneasiness can be due to various reasons. We exhibit this through certain signs which are called symptoms.
  • Symptoms help physicians in accurately determining the diseases and hence prescribe a proper treatment or course of action.
  • The process of studying the symptoms in a person as a result of a disease is called diagnosis
  • The diagnosis can either occur through a physical examination or by reading briefly through the medical history of the patient.
  • In some cases, tests are carried out to discover the underlying cause of a disease.
  • The diagnosis helps in organizing a medical condition into separate categories which allow easy prognosis and treatment.
  • Health care professionals carry out medical diagnostic procedures to suggest treatment and also suitable measures to prevent the occurrence of the same disease in the near future.
  • Diagnostic procedures utilize numerous approaches such as:
    • Differential algorithm
    • Pattern recognition
    • Diagnostic criteria
    • Diagnostic workup
    • Optical coherence tomography
    • Medical algorithms
