Edema occurs when excess fluid gets trapped in the body's tissues, leading to swelling. It's often visible in the feet, ankles, and legs but can occur anywhere in the body. The condition can result from varying causes, including standing for long periods, pregnancy, or more severe issues like heart failure or kidney disease. Recognizing edema early can prevent more serious complications.

Several factors can increase the risk of developing edema. Heart problems, like heart failure, can lead to fluid buildup. Kidney issues can prevent the body from properly excreting excess fluid, while liver problems, like cirrhosis, can disrupt the balance of proteins and fluids. Additionally, certain medications, including some for high blood pressure, can contribute to the risk of edema.

Preventing edema involves addressing its underlying causes. For those with heart or kidney issues, following a low-sodium diet can help reduce fluid retention. Staying active and elevating the legs can alleviate symptoms. For medication-induced edema, discussing alternative options with healthcare providers is essential for effective management.

Understanding the risk factors for edema can help in managing and preventing its occurrence.
