It is a neurological disorder characterized by a persistent fear or belief in the predominance of various somatic symptoms. Patients repeatedly seek medical attention for these symptoms, and various negative medical tests and physician explanations fail to dispel their doubts. Even though sometimes the patient does have some kind of somatic disorder, it does not explain the nature and extent of the symptoms and the patient’s notions of distress and predominance. These somatic symptoms are thought to be the result of psychological conflicts and personality tendencies, but for patients, they refuse to explore the possibility of a psychological etiology even if the symptoms are closely related to stressful life events or psychological conflicts. Patients often have semi-anxious or depressed moods. Most of these patients are initially seen in various medical and surgical departments, and psychiatrists are often encountered with specific years of visits, extensive clinical examination data, and cases that have been treated with multiple medications or even surgical procedures with poor results. The current low recognition rate of such patients by physicians in the same department often results in delays in the diagnosis and treatment of these diseases and the resulting huge waste of medical resources. Therefore, it is of great practical importance to improve the recognition of somatoform disorders by contemporary physicians in various disciplines. Somatoform disorders include somatization disorders, undifferentiated somatoform disorders, hypochondriac disorders, somatoform autonomic disorders, somatoform pain disorders, and many other forms. The disorder is more common in women, and the age of onset is mostly before 30 years. There is a lack of comparable epidemiological data due to differences in diagnostic criteria from country to country. Few systematic observations have been reported regarding the prognosis of somatoform disorders. It is generally accepted that the prognosis is good for those with an acute onset with obvious psychogenic triggers. If the onset of the disease is slow and the duration of the disease lasts more than 2 years, the prognosis is poor.
