Pathophysiology Functional (physiologic) changes in the body as a
result of disease
Uses knowledge of basic anatomy & physiology
Includes aspects of pathology, which describes
structural changes in body tissues caused by disease
Cause and effect relationships, defined by signs &
symptoms, guide the study of specific disease
Homeostasis Maintenance of a relatively stable internal
environment regardless of external changes
Homeostasis maintained = good health maintained
Homeostasis not maintained = development of
disease
Health Physical, mental, & social well-being
"Normal" values occur within a range of values & may
vary depending on factors
Adjustments for the following:
o Age
o Gender
o Genetics
o Environment
o Activity level
,Prevention of Disease Primary focus in health care
Examples:
• Maintaining routine vaccination programs
• Participation in screening programs
• Community health programs
• Regular routine doctor visits
New Development & Trends Constant updating of information & knowledge
Improved diagnostic tests
Development of more effective drugs
New technologies
Extensive research in efforts to prevent, control, or
cure many disorders
Gross level organ or system level
Microscopic level cellular level
Biopsy excision of small amounts of living tissue
Autopsy examination of the body and organs after death
, Disease Process & Causes Diagnosis = Identification of a basic disease
Evaluation of signs & symptoms
Laboratory tests
Etiology = Causative factors in a particular disease
Congenital defects
Inherited or genetic disorders
Microorganisms
Immunologic dysfunctions
Degenerative changes
Malignancy
Metabolic, nutritional problems
Trauma, burns, environmental factors
Causes of Disease
Idiopathic = unknown cause
Iatrogenic = caused by error/treatment/procedure
Nosocomial = acquired in healthcare facility
Predisposing factors
Age
Gender
Inherited factors
Environment
Prophylaxis
Preserve health
Prevent spread of disease
Prevention
Vaccinations
Dietary/Lifestyle modifications
Prevention of potentially harmful activities
Characteristics of Disease Pathogenesis = Development of the disease
