Definition of hysteresis

physics : a retardation of an effect when the forces acting upon a body are changed (as if from viscosity or internal friction) all manometers must be tested for hysteresis as well as for sensitivity and natural frequency— H. D. Green especially : a lagging in the values of resulting magnetization in a magnetic material (such as iron) due to a changing magnetizing force

Medical Definition of hysteresis

1 : the lagging of a physical effect on a body behind its cause (as behind changed forces and conditions) all manometers must be tested for hysteresis as well as for sensitivity and natural frequency— H. D. Green

2a : the influence of the previous history or treatment of a body on its subsequent response to a given force or changed condition a study has been made of the phenomenon of rennet hysteresis, in which the time of coagulation of heated milk is progressively greater with increase in the time interval between heating and addition of rennet— J. S. Fruton

b : the changed response of a body that results from this influence
