Blockage of lymph channels leading to interstitial fluid accumulation(swelling). What is this condition called?

Explanation:
When lymphatic drainage is blocked, the interstitial fluid that would normally be removed by the lymph vessels accumulates in the tissues, causing swelling. This specific swelling from impaired lymphatic drainage is lymphedema. It’s different from generic edema, which results from factors like increased capillary pressure or decreased plasma proteins, not from blocked lymphatics. Other terms like anasarca describe widespread edema, and ascites is fluid in the abdominal cavity, whereas lymphedema is tied to lymphatic obstruction and often affects the limbs and can become fibrotic over time.
