腎臓病、糖尿病、癌、高血圧：冠詞

慢性腎臓病に罹患している患者

ChatGPT:

A clear and natural translation of 慢性腎臓病に罹患している患者 is:

A patient with chronic kidney disease

---

Alternative, slightly more formal:

A patient suffering from chronic kidney disease

---

Notes:

• 罹患している can be translated as "with", "suffering from", or "affected by", depending on tone and context.

• In medical or clinical documents, "a patient with [disease]" is the most standard and neutral phrasing.

Let me know if you'd like to phrase it for a research paper, medical chart, or something else!

あなた:

Why "chronic kidney disease" and not "a chronic kidney disease"?

ChatGPT:

Great question — and you're really getting into the subtlety of natural medical English.

---

🔹 Why we say "chronic kidney disease" (without "a"):

Because "chronic kidney disease" is treated as a non-countable, general disease category, not as one of many individual diseases. It's similar to how we talk about:

• diabetes, not a diabetes

• cancer, not a cancer (unless specifying types, e.g., a cancer of the liver)

• hypertension, not a hypertension

In medical English, when we refer to well-defined disease categories — especially those recognized as syndromes or diagnostic classifications — we almost always omit the article.

---

🔹 When a would be appropriate (rarely in this case):

You might use "a" when referring to an instance of a disease or one of several types, e.g.:

• a rare autoimmune disease

• a form of cancer

But chronic kidney disease (CKD) is a defined clinical condition with staging, and is used as a fixed term, not as one instance of many chronic diseases of the kidney.

---

✅ So:

"A patient with chronic kidney disease"
is standard and natural.

❌ "A patient with a chronic kidney disease"
sounds unusual or awkward, as if you're describing some unspecified one among many unrelated conditions.
