Why do we say 高血圧 **の** 人 but 肺の病気 **がある** 人？

高血圧がある人 would be unnatural, would it?

If we are to use がある for people with a particular disease (which high blood
pressure is not), why are ＡＩＤＳの人 and 糖尿病の人 ok but not ＡＩＤＳがある人 and not
糖尿病がある人？

Perhaps, it’s about a disease name… if there’s the name of a condition
mentioned, then がある will not work… Does that make sense?

question
grammar
The use of の and がある when talking about health
It is because 高血圧 is not a disease for which physical presence is felt. As you
guess, 高血圧があるひと is not natural but not impossible. For comparison,

  * がんのあるひと is acceptable
  * 腫瘍がある人 is quite normal
  * 風邪のある人 is impossible
  * 咳のある人 is acceptable

I suppose 肺の病気の人 is avoided in order not to use の-phrases consecutively. 病気の人
is normal for _a sick person_ while 病気がある人 is basically the same but sounds
more like _a person with particular (persistent) diseases_.

answer
肺の病気の人 is natural. There is a difference I can think of though.

私は病気だ is a quality of 私.

私は肺の病気だ has a different meaning, here you are specifying what kind of disease
it is. (It's a lung disease for me)

肺の can't modify "病気だ" because it acts like a verb.

Similarly

◎私は花粉症です

○私は花粉症があります

◎私は花粉のアレルギーがあります

✕私は花粉のアレルギーです this means something else again

の can acomodate for both though, and I think the unnaturalness is just a
tendency of English speakers to avoid repetition.
