Edema refers to the abnormal buildup of fluid in the body’s tissues, leading to noticeable swelling. It most commonly affects the lower limbs—like the legs, ankles, and feet—but it can also occur in the hands, arms, and, in some cases, the face. While edema may seem harmless, it can sometimes be a sign of a more serious underlying health issue. That’s why it’s important to pay attention to it and consult a medical professional when symptoms appear.
1. What Is Edema?
Edema is not a disease in itself but a symptom that signals fluid retention in the body. It can affect anyone, though it’s more common in older adults and pregnant individuals. When swelling becomes generalized across the entire body, the condition is referred to as anasarca. Depending on its cause and severity, edema may be temporary or persistent.
2. Common Symptoms of Edema
The most visible sign of edema is swelling, especially in the legs, feet, or hands. You may also experience:
- A sensation of tightness or heaviness in the affected area
