Common symptoms in patients with undifferentiated somatoform disorder include fatigue and weakness, lack of appetite, and gastrointestinal or urinary tract discomfort. This clinical type can be seen as an atypical somatization disorder. Its symptoms are less extensive and less abundant than those of somatization disorders, and its duration is not always longer than 2 years. Currently, the etiology of many psychiatric disorders is not well understood. Over the years, professionals have developed some simple ideas based on continuous and careful observation of many mental illnesses in their lives and work practices. It is recognized that many mental illnesses are the result of anomalies arising from the interaction between the human individual and the social or natural environment. In many cases, although the external conditions are similar, the occurrence of disease can be very different, suggesting that individual characteristics play an important role in the occurrence of disease. Therefore, in order to prevent the occurrence of this type of disease, people advocate the improvement of human mental health, so that it can resist the attack of external harmful factors. This is: (1) to cultivate the development of the body as a whole, including brain function, and to foster its constant state of health, so that people are physically strong and mentally full; (2) to cultivate the healthy development of personality and strengthen exercise, so that it is compatible with the social environment and unified.
