Somatization Disorder - Explanations

Explanations

Although somatization disorder has been studied and diagnosed for more than a century, there is debate and uncertainty regarding its pathophysiology. Most current explanations focus on the concept of a misconnection between the mind and the body. Widely held theories on this troublesome, often familial disorder fit into three general categories.

The first and one of the oldest theories is that the symptoms of somatization disorder represent the body’s own defense against psychological stress. This theory states that the mind has a finite capacity to cope with stress and strain. Therefore, increasing social or emotional stresses beyond a certain point are experienced as physical symptoms, principally affecting the digestive, nervous, and reproductive systems. In recent years, researchers have found connections between the brain, immune system, and digestive system which may be the reason why somatization affects those systems and that people with irritable bowel syndrome are more likely to get somatization disorder. This theory also helps explain why depression is related to somatization. It is also experienced in very high levels in women with a history of physical, emotional or sexual abuse

The second theory for the cause of somatization disorder is that the disorder occurs due to heightened sensitivity to internal physical sensations. Some people have the ability to feel even the slightest amount of discomfort or pain within their body. With this hypersensitivity, the patient would sense pain that the brain normally would not register in the average person such as minor changes in one's heartbeat. Somatization disorder would then be very closely related to panic disorder under this theory. However, not much is known about hypersensitivity and its relevance to somatization disorder. The psychological or physiological origins of hypersensitivity are still not well understood by experts.

The third theory is that somatization disorder is caused by one’s own negative thoughts and overemphasized fears. Their catastrophic thinking about even the slightest ailments such as thinking a cramp in their shoulder is a tumor, or shortness of breath is due to asthma, could lead those who have somatization disorder to actually worsen their symptoms. This then causes them to feel more pain for just a simple thing like a headache. Often the patients feel like they have a rare disease. This is because their doctors would not be able to have a medical explanation for their unconsciously exaggerated pain that the patient actually thinks is there. This thinking that the symptom is catastrophic also often reduces the activities they normally do. They fear that doing activities that they would normally do on a regular basis would make the symptoms worse. The patient slowly stops doing activities one by one until they practically shut themselves from a normal life. With nothing else to do it leaves more time to think about the “rare disease” they have and consequently ending in greater stress and disability.
