What does dyspepsy mean?
Dyspepsy is an archaic English noun meaning indigestion — difficulty or discomfort in digesting food, often accompanied by symptoms such as heartburn, bloating, nausea, or abdominal pain. It is essentially an older variant of the word "dyspepsia," which survives as the standard clinical term for functional indigestion. Both words derive from Greek roots meaning literally "bad digestion." In its day, dyspepsy was a common complaint in medical writing and everyday speech alike, and Victorian-era literature frequently used it to explain characters' bad tempers or frail health. Today the word is obsolete outside historical contexts, though its adjective form "dyspeptic" lives on both medically and figuratively, describing a gloomy or irritable disposition. Encountering dyspepsy in an old text, a reader should understand it as a period-flavored way of saying simple indigestion.

"After the heavy holiday meal, his chronic dyspepsy returned in full force."
"The doctor dismissed his complaints as mere dyspepsy and prescribed a bland diet."
"Victorian novels are full of characters whose irritability is blamed on dyspepsy."
Rarely pluralized; the word is nearly always treated as uncountable, since it denotes a condition rather than countable instances.
"The physician recorded a range of dyspepsies among his patients."
"Dyspepsy" is simply "dyspepsia's" forgotten sibling — a Victorian-sounding word for plain old indigestion that has all but vanished from modern use.

Etymology of dyspepsy
Dyspepsy comes ultimately from the Greek elements "dys-" (bad, difficult) and "peptein/pepsis" (to digest, digestion), so the word literally means "bad digestion." It entered English alongside its sibling form "dyspepsia," borrowed through New Latin from the same Greek roots; both forms circulated in English from roughly the late 17th century onward, with "dyspepsia" eventually prevailing. The shared root also gives us "peptic," "peptide," and "eupeptic."
