What is a similar suffix to -itis in Japanese?


The humorous use of [-itis](http://www.dictionary.com/browse/-itis):

> nouns denoting abnormal states or conditions, excesses, tendencies,
> obsessions, etc. (telephonitis; baseballitis).

For baseball, I suppose 野球【やきゅう】バカ might work, but スマホ中毒【ちゅうどく】 seems too
strong, I've never heard random nouns being suffixed with 病【びょう】 or 症【しょう】,
but is that a thing in Japanese?




We have another suffix 狂｛きょう｝ in addition to your バカ and 中毒｛ちゅうどく｝.

"野球狂{やきゅうきょう｝の詩｛うた｝" is a famous Japanese baseball manga series by Shinji
Mizushima. One of the protagonists in a manga is a 50 years old baseball
player who still throws in a professional league. Even though the 53 years old
ballplayer had been rough, lost 53 points and threw 688 balls in 9th innings,
he completed his retirement game. And he cancels the retirement, since he
likes baseball.

We have another word "風狂｛ふうきょう｝" for zen-monks' an extraordinary behavior.

"厨二病{ちゅうにびょう｝" is a typical word for a self-conscious behavior which is
typical for a teenager "everyone is looking at you".

"スマホ中毒{ちゅうどく}" does not sound pathological at least for me. "中毒{ちゅうどく｝" in
daily usage, at least to me, does not imply a disease.

I can't find "症｛しょう｝" for "-itis" in a daily usage. Maybe there are some or
only for a pathology.
