Edema blister
Edema Blister
Edema blister (pronunciation: /ɪˈdiːmə ˈblɪstər/) is a type of blister that forms as a result of edema, a condition characterized by an excessive accumulation of fluid in the body's tissues.
Etymology
The term "edema" is derived from the Ancient Greek word οἴδημα (oídēma), meaning 'swelling'. The word "blister" comes from the Middle English "blister" or "blæstre", which is of unknown origin.
Definition
An edema blister is a fluid-filled sac that forms on the skin due to the swelling caused by edema. This can occur in various parts of the body, including the legs, arms, and feet. The fluid that fills the blister is often clear, but it can also be filled with blood or pus if the blister is infected.
Causes
Edema blisters are typically caused by venous insufficiency, a condition where the veins in the legs are unable to pump enough blood back to the heart. This can lead to fluid buildup in the legs, causing swelling and the formation of blisters. Other causes can include lymphedema, heart failure, kidney disease, and certain medications.
