This investigation focuses on the effect of the death of a family member on the number and type of diagnosed illnesses of the remaining members. The data on mortality and morbidity were obtained from a continuous morbidity register. A total of 225 cases of death were selected, involving 313 family members. A control group of 4909 people who had not been confronted with a death of a family member were selected. A comparison of morbidity rates for the two groups showed that morbidity rates, both for minor and serious illnesses, were affected by the death of a family member. Increases in minor illnesses occurred more often when people had been confronted with death after a chronic illness; increases in serious illnesses were mainly found among people confronted with sudden death. Surprisingly, people with nervous disorders in their medical history showed fewer diagnoses for minor illnesses after a sudden death of a family member. An explanation may be found in the basic principles of family medicine.
