Area of Science:

  • Physiology
  • Pathology
  • Anatomy

Background:

  • Edema is a common clinical sign indicating fluid accumulation.
  • It arises from disruptions in the physiological forces governing extracellular fluid volume.
  • Understanding the causes of edema is crucial for diagnosing and managing various diseases.

Purpose of the Study:

  • To review the causes of edema.
  • To utilize an anatomical approach for discussing edema.
  • To provide a comprehensive overview of edema pathophysiology.

Main Methods:

  • Literature review.
  • Anatomical analysis of fluid regulation.
  • Synthesis of information on edema etiologies.

Main Results:

  • Edema results from imbalances in hydrostatic pressure, oncotic pressure, capillary permeability, and lymphatic drainage.
  • Anatomical structures play a key role in fluid exchange and reabsorption.
  • Disruptions at various anatomical levels can lead to edema formation.

Conclusions:

  • Edema is a multifactorial condition with diverse underlying causes.
  • Anatomical understanding is essential for elucidating edema mechanisms.
  • Further research into specific etiological pathways is warranted.
