"Jeopardy!" viewers are upset with the show after it included a medical clue that many argue is incorrect and even offensive.

The clue had to do with a condition known as Postural Orthostatic Tachycardia Syndrome (POTS), a manageable condition that many in the U.S. and around the world suffer from. However, because so many people are familiar with POTS, many were quick to notice something didn't hold water on Monday's episode.

Guest host Savannah Guthrie read a clue from the Plain-Named Maladies category that read: "Postural Orthostatic Tachycardia Syndrome is also known as Grinch Syndrome because this organ is too small."

The correct answer to the prompt, according to "Jeopardy!," was "What is the heart."

However, as viewers were quick to point out on Twitter, the condition, which mostly affects women and children, is not necessarily characterized by having a small heart. In fact, Johns Hopkins Medicine notes that, while people’s heart rate is greatly affected by POTS, "the structure of the heart is normal" in most POTS patients.

The issue is more in the autonomic nervous system, which is supposed to regulate functions humans don’t consciously control such as heart rate, blood pressure, sweating and body temperature. These symptoms combined with an "exaggerated increase in heart rate when standing" are typically what POTS patients deal with, not an abnormally sized heart, according to JHM's website.

It didn’t take long before viewers who know a thing or two about POTS decided to chime in on social media and criticize the show’s clue and response.

"@Jeopardymy daughter has suffered from POTS for 5 years! She isn’t a Grinch she is a WARRIOR!!! You need to apologize to the millions who suffer daily!!!" one viewer wrote.
