Edema, also known as fluid retention or swelling, occurs when excess fluid accumulates in the body’s tissues. It can affect any part of the body, but it is most common in the legs, ankles, feet, and hands. Edema can be a sign of an underlying medical condition, such as heart failure, kidney disease, or liver disease. It can also be caused by certain medications, such as steroids and NSAIDs. In some cases, edema can be a temporary condition caused by prolonged standing or sitting, or by eating too much salty food.
Edema can be uncomfortable and can lead to other health problems, such as skin infections and blood clots. In severe cases, edema can be life-threatening. However, there are a number of things you can do to help prevent and treat edema.
