This trope is the tendency for people too often, if not outright chronically, think they are coming down with diseases based on vague symptoms.
This is usually Played for Laughs in fiction, showing these people as whiny, lazy, and/or paranoid. This is especially common among Jews making fun of themselves for being like this. These are extra funny when the disease in question isn't even real (or it's extinct), even in the work of fiction.
This can be Played for Drama though, if someone is actually debilitated by this, but it's rare. And in shows with Abusive Parents or Comedic Sociopathy, a character's genuine illness may be brusquely dismissed with accusations of this. "Pneumonia, my ass. You're just lazy!"
This can lead to a "Boy who cried 'Wolf'" moment when the hypochondriac actually does get sick.
These days, using the internet for self diagnosis has become a new tool for this trope.
A Sickly Neurotic Geek is more likely to be this than actually sickly.
Compare Terrified of Germs, Playing Sick, Hysterical Woman, Munchausen Syndrome (both when characters know they aren't actually sick), You Don't Want to Catch This (which is faking an illness for other reasons), Mistaken for Dying, Jewish Complaining (which often involves something that might get them sick).
- In Liberty Meadows Leslie the frog is a hypochondriac who diagnoses himself with anything from lead poisoning (from a pencil) to "ovarian cysts" (Leslie is male), much to Frank's frustration.
- Woody Allen is more than likely to play this character.

- This is Colin's biggest issue, in The Secret Garden. He's actually far more healthy than he thinks, but he's heard the servants whisper for most of his life how he has a hunchback and some wasting disease and weak legs that he constantly talks about how he's so ill and can't leave his room. He starts to get over it when Mary has enough, examines his back herself, and verifies that he has no lumps that shouldn't be there.
- Often appears in the Miss Marple novels and short stories. One notable case is in the story, "The Perfect Maid." A character named Emily Skinner claims to be ill and spends all her time lying in on a couch in a dark room while her sister Lavinia waits on her hand and foot. The entire village is convinced that Emily is a hypochondriac, as evidenced by the fact that she never goes to the doctor, figuring that deep down she knows the doctor would tell her that there was nothing wrong with her. It's actually this fact that convinced Miss Marple that Emily wasn't a hypochondriac, because in her experience hypochondriacs love going to the doctor. Indeed, Emily wasn't a hypochondriac, she was a thief, and the whole point of the "spend all day on a couch in a dark room" was to prevent anyone from ever getting a good look at her.
- Fairly common in the period romances of Georgette Heyer, especially among ladies of a certain age. From Black Sheep:
"Abby, does my aunt like to be ill?"
"Yes, certainly she does. Why not? She has very little to divert her, after all! It makes her the centre of attention, too, and how unkind it would be to grudge it to her! The melancholy truth is, my love, that single females of her age are almost compelled to adopt dangerous diseases, if they wish to be objects of interest."
- Cassie Stephens, the narrator of The Pistachio Prescription by Paula Danziger, has a genuine medical condition (asthma). However, she is also a hypochondriac who thinks that any mild physical complaint is caused by a serious disease. For example, she suspects that a stress-induced stomach ache is an ulcer or botulism, a headache is a brain tumor, and a small blotch on her hand is a "contagious, fatal rash."
- Thaddeus Sholto from The Sign of the Four rattles on and on about his health issues, and pesters Dr. Watson to check his vital signs. Watson never discerns any indications of illness in him, aside from this trope.
- In Three Men in a Boat, the narrator reads a medical textbook and concludes that he has every known disease except housemaid's knee. He rushes to his doctor, who gives him a Non Standard Prescription for a good meal, a long walk, a good night's sleep, and to stop reading medical textbooks.
- Dag in The Sharing Knife doesn't worry much about his own health (fortunately, given his status as Designated Victim), but he gets a little too solicitous in the first book after Fawn's malice injuries and miscarriage, and he gets really nervous in the fourth book when she gets pregnant.
Arkady: Almost all apprentices go through a phase where they're convinced they're coming down with every new disease they've just learned about. I thought you were going to be the notable exception. I suppose I didn't think it through quite far enough.
- In Parks and Recreation, Chris was born with a blood disease and it was predicted that he would die within days. As an adult, he's a health nut in ridiculously good shape, but becomes a hypochondriac and germaphobe when there's a chance of his becoming sick. This is played for both humor and drama.
- Michael's mom in Burn Notice, is hypochondriac for just the first episode.

- One example that is from the main case and not clinic duty is half of the Death in the Clouds episode.
- Scrubs has a minor recurring hypochondriac. Doctors dread taking his case. Naturally, one of the times he came he did have something wrong with him, and wound up suing the hospital for ferrying him between Kelso and Dr. Cox rather than actually finding out what was wrong. Doubly-subverted, as the lawsuit itself was portrayed as another instance of his craving attention.
- Star Trek: The Next Generation actually predicted something happening before it was reality: hypochondriacs diagnosing themselves over the internet! In the episode "Realm of Fear", Reg Barclay looks up symptoms for various diseases, including transporter psychosis.
- Star Trek: Voyager:
- In the episode "Author, Author", the EMH wrote a holonovel called Photons be Free which featured characters that were thinly disguised expies of the Voyager crew. When Harry Kim ran the program, he encountered his character, Kymble, who was worrying about the possibility of their decompiling the fictional EMH because there were probably millions of new viruses in the Delta Quadrant and he'd probably end up catching half of them. "Great," grumbled the real Harry Kim, "my character's a hypochondriac."
- In the episode "Good Shepherd", Crewman Telfer is revealed to be a major hypochondriac who visits Sickbay about once a week complaining of illness, only for the doctor to find nothing wrong (although his fears do become reality later in the episode when an alien briefly invades his body).

John Oliver made the scheduled takeover at the faux conference, but made this quip.
- Later on, Jon asks whether he should be Catholic and turn his blood into wine.
- The Who song "Doctor, Doctor" (by John Entwistle) takes this to ludicrous extremes:

And today I've got the mumps
And tomorrow I'll catch chicken pox as well
- This song from the musical revue Out Of My Head.

"See? I told you! Remember last week when I was feeling overtired and thought I had rickets? I was probably right about that too!"
- Argan, the title character in Molière's The Hypochondriac (Le Malade Imaginaire). According to his brother, Argan is actually a very healthy person, since he survived all the needless and harmful medical treatment he got.

- In The Odd Couple, on top of being a neat freak, Felix is also a hypochondriac. He frequently keeps treating himself of ailments that he may or may not have. It was also noted that on New Years, he chugged a bottle of Pepto Bismol. It's just another trait that adds to his neurosis.
- In The Non-Adventures of Wonderella, Wonderella once thought she'd come down with bird flu.

- Implied with Saku Hotakainen in the Stand Still, Stay Silent prologue. His introduction blurb describes him as "usually 'dying' from something" and he is true to that desciption when he seems to think his current bout of seasickness is going to kill him. He appears in the prologue segment confirming the Rash to be deadly and not just the fast-spreading but non-lethal sickness that it was presented as in the previous segments. This reveal is made via a newscast watched (alone) by Saku's young nephew, whose first reflex is to tell Saku about it. Saku's reponse to the information is hoping he actually has the Rash. He's shown to be fine two weeks later, which is the incubation time of the disease.
- SCP-1025, a medical book that was thought to induce diseases upon anyone who reads it, when in reality it induces extreme hypochondria by proxy. A rare case of the trope not being played entirely for laughs, because the book ends up causing a panic in the site which caused the death of one agent.
- SuperMarioLogan: Each time Bowser watches a Charleyyy and Friends skit where Charleyyy catches a disease of any sort, he winds up believing that he has the aforementioned disease.
- Teri in The Amazing World of Gumball is a hypochondriac with serious germophobia. It's implied it's the result of her mother (who is a doctor who also has a website with graphic images on various diseases and conditions, so she likely was raised with an... overtly cautious mentality.) The irony is that she is also a paper bear (as in a living paper cutout of a bear) so she probably wouldn't deal with any diseases.
- This was shown off in her Day in the Limelight episode, spending the day with Darwin and Gumball. The school nurse is severely annoyed by her due to her hypochondria and both Gumball and Darwin grow annoyed with her about this (and her somewhat smug attitude). Ironically enough. she is somewhat right in this episode as Gumball not cleaning his hand for weeks lad to the birth of a super-virus (though her forcing to wash his hand drowned all but one virus, who vengefully chases the three down to infect them and later the world)
- Camp Candy: Iggy is so convinced there's something wrong that he visits the infirmary more than anyone else. His parents are much worse.
