About
The character "瘘", with its traditional form "瘺", originates from medical terminology for a fistula, structured with the sickness radical "疒" and the component "屚" in the traditional version, where "屚" implies leakage, directly relating to the condition's discharge of fluids. The simplified form replaces "屚" with "娄", which functions phonetically rather than semantically. Throughout its history, the character's meaning has remained specifically tied to abnormal passages or ulcers that exude bodily fluids, consistently used within medical contexts without broadening beyond this specialized sense.
