Biological sensitisation and psychological amplification: gateways to subjective health complaints and somatoform disorders.

Subjective health complaints without known physical pathology are common and might develop into somatoform disorders. Normalization of neuroticism and anxiety in patients with duodenal ulcer disease after a relapse-free state is acquired and maintained is an indication that biological factors influence psychological factors. Recent research has shown that psychological and behavioural changes, on the other hand, have the capacity to change the brain. Visceral hyperalgesia is an example of biological sensitisation, but the abnormal sensory perception can be normalised by hypnotherapy. The dual-etiology hypothesis of functional somatic syndromes implies that in some patients with somatoform disorders there is a predominant biological etiology, whereas in others there is a predominant psychological etiology. The theory is supported by recent research, and may result in better handling of patients. Cognitive factors like catastrofising amplifies subjective physical symptoms and emotions effect the perception of them. In preventive health care the following slogans are proposed as antidotes preventing subjective health complaints form developing into somatoform disorders: Do not listen to your body's signals! Do not trust your feelings! Do not trust your thoughts!
