Here's a more detailed explanation:
* Edema is the medical term for swelling caused by fluid buildup in the body's tissues.
* Extremities refer to the arms and legs.
* Fluid buildup can occur due to various factors, including:
* Increased pressure in blood vessels: This can occur due to heart failure, venous insufficiency, or deep vein thrombosis.
* Decreased protein levels in the blood: This can occur due to liver disease or malnutrition.
* Blockage of lymphatic drainage: This can occur due to infection, surgery, or cancer.
* Inflammation: This can occur due to injuries, infections, or allergies.
Symptoms of edema in the extremities include:
* Swelling in the arms or legs, often noticeable in the ankles, feet, or hands.
* Pitting edema, where a depression remains after pressing on the swollen area.
* Tightness in the skin.
* Pain or discomfort.
Causes of edema in the extremities can vary, so it's important to see a doctor to determine the underlying cause and receive appropriate treatment.
