In literature, “dyspeptic” is employed with remarkable flexibility, serving both literal and figurative purposes. Writers use it to depict individuals who are not only physically troubled by gastrointestinal discomfort but also metaphorically burdened by melancholy, irritability, or a sour disposition. For instance, the term helps evoke a sense of languor and discontent in characters such as a disheartened clergyman or a weary captain, whose moods seem as sour as an indigestion-produced gloom [1, 2]. At the same time, “dyspeptic” is often applied to describe a distinctive appearance—whether it be a sallow professor, a dismal hobo, or someone whose very countenance embodies a state of perpetual dissatisfaction [3, 4]. By interweaving physical symptoms with emotional discontent, authors create multifaceted portraits that blur the line between bodily ailment and a brooding, cynical temperament [5, 6, 7].
