What is lymphedema?
Lymphedema is swelling due to the build-up of lymph fluid in the body.
Lymph nodes act like a drain in your sink. If the drain is clogged, the fluid cannot drain.
It usually happens in the arms or legs but can occur in the other parts of the body.
Stages of Lymphedema
Stage 1: Abnormal flow in the lymphatic system. No signs or symptoms.
Stage 2: Accumulation of fluid with swelling.
Stage 3: Permanent swelling that does not resolve with elevation.
Stage 4: Elephantiasis (large, deformed limb), skin thickening with "wart-like" growth and extensive scarring.
