Diathesis

Diathesis (plural: diatheses) is a term used to describe a state in which there is an increased chance of something happening. Contemporaneously, the word is used as a synonym for the word predisposition; however the term predates a modern understanding of genetics or pathology .

Most commonly the term is now seen used to describe 'bleeding diatheses', which implies certain conditions with an increased risk of hemorrhage in particular patients, e.g. due to coagulopathy.
