The biopsychosocial model explains that health and illness are consequences of the interplay of biological, psychological, and social factors. This means that illness doesn’t necessarily come from a virus or something else intruding in the body. It may come from a source we may not expect.
My Dad is a cardio-thoracic surgeon and his experience has shown him several examples of the biopsychosocial model. He says that when some of his patients suffer heart attacks, their family members begin to complain of chest pain. This pain is real and may result from the stress of having something traumatic happen to someone they have a close social relationship with.
Another example is when one of his patients suffers a heart attack and then thinks that every little thing they feel after that is chest pain. They constantly call the office complaining of chest pain. This reaction comes from the psychological fear they have experience from enduring a heart attack. This pain is often not real and exists only in the patient’s head. These two examples of heart attack patients illustrate the biopsychosocial model.
