Oedema (also spelled edema) refers to the accumulation of fluid in the interstitial spaces between cells in the body. It can occur anywhere in the body but is most commonly seen in the hands, ankles, feet, and legs.
Oedema can be caused by a variety of factors, including:
Increased hydrostatic pressure: This occurs when the pressure within blood vessels increases, causing fluid to leak out into the surrounding tissues.
Reduced oncotic pressure: This occurs when the amount of protein in the blood decreases, leading to an imbalance in the pressure between the blood vessels and surrounding tissues.
Lymphatic obstruction: This occurs when the lymphatic system, which helps to remove excess fluid from the body, is blocked or damaged.
Inflammation: This can cause increased permeability of blood vessels, allowing fluid to leak out into the surrounding tissues.
Oedema can present as swelling, puffiness, or a feeling of tightness or heaviness in the affected area. Treatment options depend on the underlying cause and may include medications, lifestyle changes, and medical procedures.
