Causes of Edema - Differential Diagnosis

Pitting Edema:

  ↑ Hydrostatic - Too Much Fluid

     • RAAS Activation

     • Inability to Excrete

     • Iatrogenic

  ↑ Hydrostatic - Too Much Pressure

     • Internal Obstruction

     • External Venous Obstruction

     • Venous > Arteriole Pressure

  ↓ Oncotic - Not Enough Protein 

     • Decreased Production

     • Increased Loss

  Leaky Capillaries

     • Inflammatory

Non-Pitting:

  Not Enough Drainage

     • Lymphatic Obstruction

     • Too viscous
