A systemic disease is a condition that affects multiple organs and tissues, or the body as a whole. Unlike localized diseases, which affect a specific part of the body, systemic diseases can have widespread effects and often involve complex interactions between different bodily systems.

Classification[edit]

Systemic diseases can be classified based on their etiology, including:

Autoimmune diseases: Conditions where the immune system attacks the body's own tissues, such as systemic lupus erythematosus and rheumatoid arthritis.
Infectious diseases: Diseases caused by pathogens that spread throughout the body, such as HIV/AIDS and tuberculosis.
Metabolic disorders: Conditions that affect the body's metabolism, such as diabetes mellitus and hyperthyroidism.
Genetic disorders: Diseases caused by genetic mutations, such as cystic fibrosis and Marfan syndrome.

Pathophysiology[edit]

The pathophysiology of systemic diseases varies widely depending on the specific condition. However, common mechanisms include:

Inflammation: A key feature in many systemic diseases, where the body's immune response leads to tissue damage.
Autoimmunity: The immune system mistakenly targets the body's own cells.
Infection: Pathogens spread through the bloodstream or lymphatic system, affecting multiple organs.
Metabolic imbalance: Disruptions in normal metabolic processes can lead to systemic effects.

Symptoms[edit]

Symptoms of systemic diseases can be diverse and may include:

Diagnosis[edit]

Diagnosing systemic diseases often requires a combination of:

Medical history and physical examination
Laboratory tests: Including blood tests to check for markers of inflammation or infection.
Imaging studies: Such as X-rays, CT scans, or MRI to assess organ involvement.
Biopsy: Taking a tissue sample for analysis.

Treatment[edit]

Treatment strategies for systemic diseases depend on the underlying cause and may include:

Pharmacotherapy: Medications such as immunosuppressants, antibiotics, or hormone replacement therapy.
Surgery: To remove or repair affected tissues or organs.
Lifestyle modifications: Including diet, exercise, and stress management.
Supportive care: To manage symptoms and improve quality of life.

Prognosis[edit]

The prognosis for systemic diseases varies widely. Some conditions can be managed effectively with treatment, while others may lead to chronic disability or be life-threatening.

Research and Future Directions[edit]

Ongoing research into systemic diseases focuses on:

Understanding the genetic and environmental factors that contribute to these conditions.
Developing targeted therapies that address the underlying mechanisms of disease.
Improving diagnostic techniques for earlier and more accurate detection.

-'''System''' ([[Latin language|Latin]] ''systēma'') is a group of related things that work together as a whole. These things can be [[real]] or [[imagination|imaginary]]. Systems can be man-made things like a car [[engine]] or natural things like a [[star system]]. Systems can also be [[concepts]] made by [[people]] to organize [[idea]]s.
+A '''systemic disease''' is a condition that affects multiple organs and tissues, or the body as a whole. Unlike localized diseases, which affect a specific part of the body, systemic diseases can have widespread effects and often involve complex interactions between different bodily systems.
-A '''subsystem''' is a system that is part of some larger system. For example, in [[Computer network|computer networking]], a disk subsystem is a part of a computer system.
+==Classification==
+Systemic diseases can be classified based on their etiology, including:
-== Definition ==
+* [[Autoimmune diseases]]: Conditions where the immune system attacks the body's own tissues, such as [[systemic lupus erythematosus]] and [[rheumatoid arthritis]].
-*A system is a group of things that connect and form some kind of coherent whole.
+* [[Infectious diseases]]: Diseases caused by pathogens that spread throughout the body, such as [[HIV/AIDS]] and [[tuberculosis]].
+* [[Metabolic disorders]]: Conditions that affect the body's metabolism, such as [[diabetes mellitus]] and [[hyperthyroidism]].
+* [[Genetic disorders]]: Diseases caused by genetic mutations, such as [[cystic fibrosis]] and [[Marfan syndrome]].
-== What systems do ==
+==Pathophysiology==
-Systems are a way to describe a set of items, or people, or things that are related. Most systems describe ways of making them work together, or why they work together already. Some systems are nothing more than a different way of looking at a problem, or thinking about a job being done.
+The pathophysiology of systemic diseases varies widely depending on the specific condition. However, common mechanisms include:
-Other systems are more like organizing books on a shelf, so that people can find things more simply, without having to search. These can be systems about how to program computers or manage people.
-== Example ==
+* [[Inflammation]]: A key feature in many systemic diseases, where the body's immune response leads to tissue damage.
-The [[Solar System]] is a great example of a system. The Solar System is made up of the [[Sun]] and the 8 planets, as well as the moons of those planets. The related "things," or plants, work together as a whole to form a full [[planetary system]].
+* [[Autoimmunity]]: The immune system mistakenly targets the body's own cells.
+* [[Infection]]: Pathogens spread through the bloodstream or lymphatic system, affecting multiple organs.
+* [[Metabolic imbalance]]: Disruptions in normal metabolic processes can lead to systemic effects.
-== Types of systems ==
+==Symptoms==
-There are many kinds of systems. A system can refer to:
+Symptoms of systemic diseases can be diverse and may include:
-* Systems in a person's body, such as [[digestive system]], [[nervous system]], and so on. These systems operate so as to keep the body's [[physiology]] going within limits.
+* [[Fatigue]]
-* Computer systems, like systems of counting or finding things
+* [[Fever]]
-* Systems in planning, like deciding how a [[bridge]] should be made
+* [[Weight loss]]
-* Systems in social science, like the way humans talk, think, and feel
+* [[Joint pain]]
-* Systems in management and business, such as ideas about parts of companies
+* [[Skin rashes]]
-* Systems of life, such as [[life cycle]], [[carbon cycle]], [[ecosystem]], or [[visual system]]
+* [[Organ dysfunction]]
-* Systems in science, such as the  [[solar system]]
-* Systems of [[symbol]]s such as [[writing system]] or [[number system]]
