Induced Hypochondria

Go To

Bear: My head...? Why, I never knew it was crooked before! But, now that you say so, it does feel quite funny.
Rabbit: I bet that it hurts you a lot, I bet that it hurts you right down to your tail! My! My! Mr. Bear, you look horribly pale! Say... ! How does your throat feel? A little bit prickly?
Bear: It does! And my stomach feels tickly! Poor me! I feel all-over sickly!
— "The Rabbit, the Bear, and the Zinniga-Zanniga" by Dr. Seuss

When a character convinces another (perfectly healthy) character that they are ill, often in order to get them out of the way for a little while, or just to mess with their head. To accomplish it, they may employ fast talking, medical jargon, obviously fake medical devices, etc.; they might even make up a whole new disease. Expect them to say "You don't look so good," or "You're a very sick man."

The victim almost always falls for it, often expressing a desire to "go lie down". May result in Your Days Are Numbered and/or Mistaken for Dying. This trick cannot, however, actually hurt or kill a person like in the case of the Compelling Voice or Your Mind Makes It Real. Typically Played for Laughs. Compare Gaslighting, and You Don't Want to Catch This.

In an inverse, sometimes a fictional disease will be whipped up that has no symptoms and apparently only targets healthy people and is allegedly fatal. This is employed almost exclusively on very gullible people.

A Sub-Trope of Hypochondria. Compare Münchausen Syndrome By Proxy, which involves actually making someone sick in order to get positive attention from others for taking care of them. See also Faking Another Person's Illness, in which the goal is to persuade a third party. If someone tries to scare someone with a story concerning a disease that, for instance, "is especially bad for X" when the listener is an X, then it's overlapping with Scarily Specific Story.
