水腫

1. Origins, structure, and basic meaning

• Structure: 水腫 is read as すいしゅ and is a medical noun for edema, swelling caused by an abnormal accumulation of fluid in tissue.
• Basic usage: Use 水腫を説明する for a clinician’s explanation and 脚に水腫が見られる for edema observed in a body part.

2. Common pitfalls and similar expressions

• Medical scope
  • It is a clinical condition term and should not automatically label every brief instance of everyday puffiness.
• Do not infer a diagnosis
  • The examples involve medical explanation and further testing; the word alone does not establish a cause or complete diagnosis.
