n any one of the factors that contribute to susce-ptibility to a disease by weakening the body's ability to defend itself, such as stress and dietary deficiencies.
in diseases, an agent, event, condition or characteristic which plays an essential role in producing an occurrence of the disease. Because there is nowadays much less certainty about what actually establishes a disease state it is becoming more common to use terms such as disease determinants, causal association, causal relationship. koch's postulates are no longer the sole criterion used in establishing causality.

the cause comes from within the patient. See also constitutional cause (above).
the cause comes from outside the patient, e.g. a virus infection.

see endogenous cause (above).

the trigger mechanism that initiates the commencement of the disease state.
a mechanism that makes a patient more susceptible to the precipitating cause.
the principal factor in causing the disease.
a factor that assists the primary cause. A cause of secondary importance.
