What does dyspeptic mean?
Dyspeptic describes someone who is irritable, gloomy, or chronically bad-tempered, as well as anything relating to indigestion. It derives from Greek roots meaning 'difficult digestion,' and its figurative use rests on the old idea that a troubled stomach makes for a troubled temper. In everyday modern usage, the temperamental sense dominates: a dyspeptic reviewer grumbles through every film, and a dyspeptic letter bristles with complaint. The word carries a mildly humorous, literary flavor, suggesting not explosive rage but a settled, sour discontent — the temperament of someone perpetually displeased before breakfast. Its literal medical sense, describing actual indigestion or those who suffer from it, still appears in clinical and older texts. Useful precisely because it names a familiar personality type with wit rather than cruelty, dyspeptic adds color to descriptions of curmudgeons, pessimists, and habitual complainers.
Irritable, gloomy, or ill-tempered; also, relating to or suffering from indigestion.
"A famously dyspeptic food columnist, he could find fault with any meal set before him."
The figurative sense is far more common today than the literal medical one.
A person who suffers from dyspepsia (indigestion); occasionally, a habitually irritable person.
"The clinic specialized in treating dyspeptics whose complaints resisted every conventional remedy."
As a noun, the word is somewhat dated and chiefly medical or historical in tone.
Used when referring to multiple people suffering from indigestion or, figuratively, multiple grumpy individuals.
"Victorian novels are full of dyspeptics blaming their tempers on their livers."
Dyspeptic literally means 'bad digestion' — but English speakers loved it so much for describing grumpy people that the mood sense now outshines the medical one.

Etymology of dyspeptic
Dyspeptic comes from the Greek 'dyspepsia', formed from 'dys-' (bad, difficult) and 'peptein' (to digest), so it literally means 'badly digesting.' The term entered English via New Latin medical vocabulary in the late 18th century, first used strictly of digestive disorders. By the early-to-mid 19th century, writers had extended it figuratively to describe irritable, sour-tempered people, on the assumption that chronic indigestion soured the disposition. It shares its Greek root with 'peptic', 'pepsin', and 'eupeptic'.
