Lymphedema is the swelling of a human body part caused by an abnormal accumulation of fluid, proteins, and cellular waste in the tissues under the skin. It occurs when there is a problem in the lymphatic system:
The lymph system consists of a network of lymph vessels carrying lymph fluid to lymph nodes. The lymph vessels are located all over the body (usually next to veins) and transport lymph fluid
There are two general types of lymphedema:
Primary Lymphedema usually appears without obvious cause or after a minor traumatic event or an infection. It can happen at any age, but is due to a congenital abnormality, usually involving malformed or missing lymph vessels. This condition may be familial.
Although most cases of lymphedema are diagnosed on a patient's history and clinical findings, lymphoscintigraphy (isotope lymphography) is now considered
LYMPHEDEMA CALLED PODOCNOIOSIS: This is lymphedema caused by walking barefoot or direct exposure to the clay soils of Ethiopia.
LIPEDEMA: a symmetrical “swelling” of both legs, extending from the hips to the ankles, caused by deposits of subcutaneous adipose (fatty) tissue. The underlying etiology of these fat deposits remains unknown. While lipedema is not a disorder of the lymphatic system per se, it is frequently confused with bilateral lower extremity lymphedema.
