(πληθωρία, fulness), in Medicine, is when the vessels are too much loaded with fluids. A plethoric state is marked by plumpness, fulness of countenance, a high colour, frequent dimness of sight, and ringing of the ears. It is often accompanied by corpulency, and a great accumulation of fat about the belly. It is generally the consequence of high living, of idleness, with much indulgence in sleep and luxury. Plethoric people are liable to a long train of dangers and inconveniences. They are apt to lose breath, to perspire on the slightest exertion, to headache, to vertigo, to palsy, to apoplexy, to bluntness of faculties, to stomach complaints, to low spirits, and a variety of other uncomfortable sensations. Bleeding is not considered good for plethora. In addition to regimen and the care of the general health, frequent purgatives are proper; and a course of mineral waters is frequently very salutary.
