Genetics probably contributes a very small amount to development of the disorder.One of the oldest explanations for somatization disorder advances the theory that it is a result of the bodys attempt to cope with emotional and psychological stress. The theory states that the body has a finite capacity to cope with psychological, emotional, and social distress, and that beyond a certain point symptoms are experienced as physical, principally affecting the digestive, nervous, and reproductive systems. There are many different feedback systems where the mind affects the body; for instance, headaches are known to be associated with psychological factors, and stress and the hormone cortisol are known to have a negative impact on immune functions. This might explain why somatization disorders are more likely in people with irritable bowel syndrome, and why patients with SSD are more likely to have a mood or anxiety disorder. There is also a much increased incidence of SSD in people with a history of physical, emotional or sexual abuse.Another hypothesis for the cause of somatization disorder is that people with the disorder have heightened sensitivity to internal physical sensations and pain. A biological sensitivity to somatic feelings could predispose a person to developing SSD. It is also possible that a persons body might develop increased sensitivity of nerves associated with pain and those responsible for pain perception, as a result of chronic exposure to stressors.Cognitive theories explain somatization disorder as arising from negative, distorted, and catastrophic thoughts and reinforcement of these cognitions.
