Nocebo and the psychogenic generation of illness

The biopsychosocial model claims that illness is generated by both biological and psychosocial factors. The nocebo response is an excellent model and approach to understand these effects and their psychophysiological underpinnings, as nocebos are made of negative psychological and social factors, such as negative expectations and social interactions. There is today experimental evidence that nocebos can create symptoms and illness from nothing, whereby a combination of biological, psychological and social factors interact with each other in the generation of symptoms and illness. Several biochemical pathways have been identified, e.g. cholecystokinin and cyclooxygenase, and the activation of these mechanisms have been found to take place in adulthood and as early as in prenatal life. The study of placebo and nocebo oxygen has been crucial to unravel these mechanisms. Therefore, the investigation of oxygen-related conditions, such as hypoxia, represents today an excellent approach to understand how nocebos can generate illness from nothing.
