What does eupeptic mean?
Eupeptic describes something relating to good digestion—the state of digesting food easily and healthily. It comes from Greek roots meaning 'well' plus 'digest', and its opposite is dyspeptic, which covers both poor digestion and, by extension, a sour or irritable mood. Because nineteenth-century medicine linked temperament closely to the stomach, eupeptic acquired a figurative second life: a eupeptic person is cheerful, contented, and untroubled, as if their sunny outlook flowed directly from an efficient digestive system. Today the word appears mainly in formal medical contexts or in literary and humorous prose, where it lends a polished, faintly Victorian flavour. Calling someone eupeptic suggests both physical robustness and equable good humour—a neat way of saying they take life, and lunch, in comfortable stride.
Characterized by healthy digestion; promoting good digestion.
"The doctor recommended a eupeptic regimen of small meals and gentle exercise."
(Of a person or mood) Cheerful and contented, as if resulting from good digestion.
"He remained eupeptic despite the delays, cheerfully ordering another round of coffee."
In Victorian medicine, a 'eupeptic' person was one whose good mood was credited quite literally to an excellent stomach.

Etymology of eupeptic
Eupeptic derives from the Greek eupeptos, formed from eu- ('good' or 'well') and peptein ('to digest'), the same root that gives us peptic, dyspeptic, and the enzyme name pepsin. The word entered English via scientific Latin in the early nineteenth century, when physicians coined a family of eu-/dys- terms for states of bodily function. Its figurative extension to cheerful temperament reflects the era's conviction that mental outlook followed from bodily condition.
