Decoding Edema: Understanding Swelling in Your Body
Published: Aug 03, 2024
Edema is a medical term for swelling caused by excess fluid in body tissues. It can affect various parts of the body and may signal underlying health issues.
Types of Edema
Edema can occur in different parts of the body. Peripheral edema affects the limbs, often the legs and feet. Pulmonary edema involves fluid in the lungs, causing breathing difficulties. Ascites refers to fluid buildup in the abdomen. Each type can have different causes and implications for your health.
Recognizing Edema
The most common sign of edema is swelling. In peripheral edema, you might notice puffiness in your ankles or legs. If you press on the swollen area, it may leave a dent - this is called pitting edema. Pulmonary edema often causes shortness of breath, especially when lying down. Ascites can lead to a swollen, tight abdomen.
Causes of Edema
Many factors can lead to edema. Heart, kidney, or liver problems can cause fluid retention. Venous insufficiency, where blood doesn't flow properly through veins, is a common cause of leg edema. Sometimes, medications or hormonal changes can trigger swelling. In some cases, edema may be a sign of a more serious condition like deep vein thrombosis or cancer.
