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, Münchausen 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).

- Woody Allen is more than likely to play this character.
- In Amélie, Georgette, a coworker of Amélie's, is shown constantly taking medications of various kinds, even inhalers and eyedrops.
- In Carry On:

- In Sherlock Holmes (1932), Alice's father is a hypochondriac and spends much of his time onscreen bemoaning his various supposed ailments.
- Ultraman Zearth: The titular Ultra is deathly afraid of dirt and slime, and freaks out from merely touching even a little bit of dust. Naturally he needs to spend the entire movie getting over his fear of dirt, and the villain Alien Benzene exploits his weakness by challenging Zearth to fight him in the middle of a sludge pool.
- In Castle Hangnail, the goldfish is a hypochondriac, and swims around her bowl in a sweater and scarf to ward off the chills. It's a sign of how serious things have become at the climax when she stops worrying about her health, and a sign of things returning to normal when she starts again.
- 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."
- This is Zena's problem in Ethan Frome. It is one reason (along with her nagging and complaining) why Ethan wants to leave her.
- Eddie Kaspbrak from It is frail and asthmatic hypochondriac, who carries his inhaler with him everywhere. His father died when he was very young, and his mother is domineering and constantly worries about his health, encouraging his fears around his poor health and deliberately instilling hypochondria in him.
- 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.
- 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."
- 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.
- 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.
- 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.
- The Beverly Hillbillies: Mrs. Drysdale was originally such a hypochondriac, she had even made her poodle Claude a hypochondriac as well! However, this trait disappeared after the first couple seasons.
- Better Call Saul: Chuck suffers from Electromagnetic hypersensitivity, a psychosomatic illness where being near any electromagnetic fields causes someone pain. In season 1, a doctor turns on an electric medical device without Chuck's knowledge to determine that the illness is just in his head. In season 3, Jimmy proves it again in his disbarment hearing by slipping a battery into Chuck's pocket without Chuck suffering any ill effects. After this, Chuck begins to consider whether he's ruined his life for nothing. He finally admits he's mentally ill and begins treatment for it. Part of the thing about it is that Chuck is right that he has an illness, but it's generally implied that he's wrong about the cause: he thinks it's an irreversible physical condition, but it actually seems to be a mental condition that produces physical symptoms and could probably be treated if he'd put in the work, but by the time he realizes this, it's much too late for him.
- Sheldon of The Big Bang Theory is Terrified of Germs and prone to occasional hypochondria. In one episode, he gets a stomach ache from eating too many brussel sprouts and thinks it's cholera.

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.
- Emergency! had a couple of patients like this. At least one turned out to really be sick on one call.
- Another is a precocious boy who is overreacting to a minor ailment by thinking he has a critical condition because he was reading too many medical books.

What is plaguing Mrs. Oleson? Gas.
- The Outer Limits (1995):
- In "What Will the Neighbors Think?", Mona Bailey is a severe hypochondriac to the point that she uses a wheelchair when she is completely able-bodied. After checking her Physicians' Deck Reference, she comes to the conclusion that she has Lyme disease in spite of her husband Ned's reassurances that she would have to have been bitten by a tick to have contracted it. She is also convinced that there is radon in her apartment building, the Clackson Arms, which she has not left for six months. After she begins hearing voices, Mona worries that she may be either hallucinating or have a brain tumor but it turns out that she is hearing the thoughts of the other residents.
- In "Nest", Marcy Newhall, who works at the Peary University Research Station in the Arctic, has severe hypochrondria and checks her blood pressure every day to ensure that it remains stable.

She stabs herself in the stomach and soon dies as a result. The autopsy later determines that she was never infested with the mites in the first place.
- 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.
- 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 Turk and Dr. Cox rather than actually finding out what was wrong. Double-subverted, as the lawsuit itself was portrayed as another instance of him craving attention.
- One of the many flaws of George in Seinfeld: he is such a hypochondriac that he can't even read about symptoms or watching documentaries about a disease without thinking he has it.

- 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.

"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).

Crewman Telfer: [scanning himself with a medical tricoder] Everything!

- This song from the musical revue Out Of My Head.
- The Who song "Doctor, Doctor" (by John Entwistle) takes this to ludicrous extremes:
Doctor, thanks for seeing me today, I'm glad
I've got every sickness there is to be had
I had whooping cough last month
And today I've got the mumps
And tomorrow I'll catch chicken pox as well
- Mike Birbiglia admitted to being a hypochondriac, and at one point a malignant tumor was found inside of him. He says the best thing that can possibly happen to a hypochondriac is that they actually get cancer, because it confirms every fear they've ever had and makes them feel vindicated.
See? I told you! Remember last week when I was feeling overtired and thought I had rickets? I was probably right about that too!
- Jeff Foxworthy describes his wife as a hypochondriac. He blames on watching too much 20/20 and Dateline-type shows featuring various diseases.

Jeff: You do not have testicular cancer! You don't even have testiculars!
- In Guys and Dolls, Nathan Detroit's fiancee Adelaide is a hypochondriac, as shown in the song "Adelaide's Lament."
- 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.
- Ironically, Molière (who also plays the main role in most of his works, including this one) was very ill at this time. He collapsed on the scene at the end of a representation, then died at his home a few hours later.
- 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 Elder Scrolls IV: Oblivion, the Shivering Isles expansion, there is a Breton innkeeper in Crucible named Sickly Bernice. She is convinced that she's deathly ill, and the only cure is a special healing water found only in a cave. She will ask you to get this water from the cave in exchange for a magical ring. After that, she'll ask you to get it again, this time for just gold. Of course there is no way to convince her she's fine. Because it's the Shivering Isles.

- 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 response 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. In addition to this, when Saku's brother-in-law considers having him sleep in a tent instead of the cabin so he won't get seasick on his carpet, Saku's wife protests on the basis that he could become sick "for real".
- Bruno the Bandit: "Great Uncle" Lucius, an ancient old man who scammed his way into the household and never left, though the characters decide that he's so old that throwing him out would be rotten even to their standards even after they realize he's not actually related to any of them (ironically, the punchline to that strip showed Lucius alive well into Bruno's own old age). He's outlived several of his doctors and even subscribes to Hypochondriac Monthly that gives their readers advice on how to fake symptoms of 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 lead 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.

He ended up getting upset when the doctors found nothing wrong. In another episode, when he actually did have an illness, he got so excited, he fell down the stairs and knocked himself out.
- Kyle's east coast cousin (also named Kyle) in South Park is like this.
- What A Cartoon! Show: In "Snoot's New Squat", Snoot is a tiny alien who settles on the body of a neurotic, hypochondriac dog named Al, who annoys his doctor by worrying about things like his nose being too wet or his tail wagging abnormally. When Al tries to call his doctor about "alien fleas" infesting him, the doc thinks Al has finally cracked up and prepares to have him committed and lobotomized.
- Warner Bros.' Claude Cat is the titular "Hypochondri-Cat." The two mice Hubie and Bertie use this to their advantage.
