Pitting edema is a type of swelling that occurs when excess fluid builds up in the tissues of the body — usually in the legs, ankles, or feet — and when you press on the swollen area with a finger, it leaves a visible indentation (“pit”) that stays for a few seconds before slowly filling back up.

🧠 Why it’s called “pitting”
The term “pitting” refers to that dent or pit left behind when pressure is applied to the swollen skin.

⚕️ Common Causes of Pitting Edema
Pitting edema is usually a symptom of an underlying condition, not a disease on its own. Common causes include:
1. Heart problems
Congestive heart failure (CHF): When the heart can’t pump blood effectively, fluid backs up in the legs and feet.
Often worse in the evening or after standing for long periods.
2. Kidney disease
Damaged kidneys can’t remove excess fluid and sodium from the body, leading to swelling (often in the face, hands, and legs).
3. Liver disease (e.g., cirrhosis)
Reduced protein (especially albumin) production lowers the blood’s ability to retain fluid, causing fluid to leak into tissues.
4. Chronic venous insufficiency
Veins in the legs fail to return blood efficiently to the heart, causing fluid to pool in the lower limbs.
5. Malnutrition or low protein levels
Low albumin in the blood (from poor nutrition or liver disease) reduces oncotic pressure, leading to fluid leakage.
6. Certain medications
Examples include:
Calcium channel blockers (for high blood pressure)
Steroids
NSAIDs (e.g., ibuprofen)
Some diabetes medicines (thiazolidinediones)
7. Prolonged sitting or standing
Gravity causes fluid to pool in the lower limbs, especially in people with weak circulation.

🩺 How Doctors Assess It
Doctors grade pitting edema on a scale of 1+ to 4+:

1+ 2 mm Immediate Mild
2+ 4 mm 20 sec Very deep

⚠️ When to See a Doctor
You should seek medical attention if:
The swelling is sudden, severe, or painful
It’s accompanied by shortness of breath, chest pain, or fatigue
It affects only one leg (which could indicate a blood clot)
