Frequently Asked Questions
❓ What is edema?
Edema is the abnormal accumulation of fluid in the interstitial tissues, leading to visible or palpable swelling of body parts.
❓ What are the main mechanisms causing edema?
Edema is caused by increased capillary hydrostatic pressure, decreased plasma oncotic pressure, increased capillary permeability, lymphatic obstruction, and renal sodium and water retention.
❓ What is the difference between pitting and non-pitting edema?
Pitting edema leaves a persistent indentation when pressure is applied and is seen in cardiac, renal, and hepatic causes, while non-pitting edema does not pit and occurs in lymphedema and myxedema.
❓ Why does nephrotic syndrome cause edema?
Nephrotic syndrome causes massive protein loss in urine leading to hypoalbuminemia, reduced plasma oncotic pressure, and fluid shift into interstitial spaces.
❓ Why is edema worse in the evening in heart failure?
In heart failure, prolonged standing increases venous pressure in dependent areas, leading to fluid accumulation that worsens by evening.
❓ What causes non-pitting edema in hypothyroidism?
Deposition of glycosaminoglycans in the interstitial tissue leads to water retention, resulting in non-pitting edema called myxedema.
❓ What is anasarca?
Anasarca refers to severe, generalized edema involving the entire body, often seen in advanced heart failure, nephrotic syndrome, or liver cirrhosis.
❓ Which drugs commonly cause edema?
Common drugs causing edema include calcium channel blockers, NSAIDs, corticosteroids, and thiazolidinediones.
❓ How is edema evaluated clinically?
Clinical evaluation includes assessing pitting, distribution, timing of swelling, associated symptoms, and systemic signs such as raised JVP, proteinuria, or ascites.
❓ What is the general approach to managing edema?
Management includes treating the underlying cause, salt and fluid restriction, limb elevation, compression therapy when appropriate, and diuretics when indicated.
