Definition of Nondipper

Nondipper: A person in whom there is an absence of the normal nocturnal fall (dip) in blood pressure. Nondipper status has been shown to be an additional risk factor for the development of adverse cardiovascular events. Nondipping is also common after kidney transplant. The opposite of a nondipper is, of course, a dipper (not to be confused with the Big Dipper).
