Difference between Pathology and Disease

Pathology and disease are often concepts used as synonyms, but they present certain key differences. Pathology is the branch of medicine that studies diseases, their nature and their characteristics, while the disease is the deviation from the normal physiological state in one or more parts of the body due to causes that may or may not be known and manifests itself with characteristic symptoms. .

Pathology

It is the branch of medicine that is responsible for studying diseases in people, and in the case of veterinary pathology, in animals. It studies the structural, biochemical and functional changes caused by diseases that affect cells, tissues and organs.

It uses microbiological, molecular, immunological and morphological tools to explain the etiology and clinical manifestations presented by patients while proposing bases for the treatment and prophylaxis of diseases. It is divided into general pathology that studies the reactions of cells and tissues to abnormal stimuli and genetic problems; and systemic pathology that analyzes alterations in specialized tissues and organs.

Disease

It is the alteration of the physiological state in one or several parts of the body for reasons that may or may not be known and are manifested by typical symptoms and signs and whose evolution may be more or less predictable.

Differences between pathology and disease

  • Pathology is a science and cannot be used to define diseases.
  • Diseases are the object of study of pathology.
  • Pathology is the branch of medicine that studies and investigates the characteristics of each disease, the process they develop and their components, as well as the effects they cause in the biology of the affected organism.
  • Diseases are alterations of our natural state in which various parts of the body can be affected. They are manifested by typical symptoms and signs and whose evolution can be predictable.
