Q

Nephrology

What causes increased interstitial fluid?

Pathophysiology

A

Lymph drainage (lymphoedema)
Venous drainage and pressure (obstruction e.g., venous thrombosis)
Lowered oncotic pressure - low albumin/protein (malnutrition, decreased production or increased loss)
Salt and water retention (in the kidney due to impaired GFR or due to heart failure)

Q

Nephrology

How does nephrotic syndrome cause oedema?
