What is psychosomatic illness? In our people’s words, it means that the person has been under a lot of stress recently, whether it is due to business or personal matters, in short, anxious and angry or overworked, so first there is an abnormal mood, such as low mood, or impatient and angry, and then there is physical discomfort, such as insomnia, heart palpitations and chest tightness, stomach distension, bloating, diarrhea, constipation, bad breath, hair loss, daytime sleepiness and weakness, blood pressure and blood sugar instability And so on, a series of physical discomfort symptoms. These are psychosomatic diseases, i.e. a series of diseases that are affected by the mind (emotions) to the body (physical body). What is the pathogenesis? Chinese medicine has already built up the physiological basis and pathological theory of Chinese psychosomatic medicine as early as the era of Nei Jing. For example, in the “Ling Shu? Mouth Questions”, “Sorrow and sadness move the heart, and when the heart moves, all the five organs and six bowels are shaken.” Su Wen? The main brightness of the body is the peace of the lower, ……, and the main darkness is the danger of the twelve officials, ……” shows that the reaction of the brain to emotional stimuli affects the function of the internal organs. The main reason for this is that the brain’s response to emotional stimuli affects the function of the internal organs, and positive emotions are normal, while negative emotions impair the function of the internal organs. At present, the main research direction of modern psychosomatic medicine is in the direction of psychophysiology. In short, the stressful stimuli from the society reach the brain as a kind of information, and the brain has to recognize and evaluate and make a series of changes in the subcortical centers, which are mainly produced by the dysregulation of the vegetative nervous system, endocrine system and immune system, and then lead to the pathological changes in the target organs.
