Phytodystrophy is known in medicine as somatic form autonomic disorder, also called phytodysfunction, and its clinical symptoms are mainly as follows. Firstly, patients usually show autonomic excitement, recurrent pain of variable location, burning sensation, tightness and some other symptoms of no special significance, while these patients are often more stubborn in character and more concerned about their physical condition. Secondly, the patients have more obvious abnormal symptoms, but the results of various clinical auxiliary examinations are normal, and at the same time, if the patients themselves have some kind of physical disease, but the pain felt by the patients is often greater than the severity of their disease itself, and the patients are often accompanied by anxiety. At the same time, the patient presents with multiple symptoms, often including more than two organs, such as having cardiac or gastrointestinal-related symptoms, or involving a second system at the same time, such as having both urinary and cardiovascular system symptoms. The first occurrence of the disease is often due to psychological reasons, such as a major setback or unpleasant event in life, but patients often think it has nothing to do with it, while the disease has a long course, waxing and waning, in a state of chronic fluctuation, often accompanied by anxiety and depression. Finally, the clinical symptoms of some diseases such as anxiety disorders and neurasthenia have similarities with those of phytodystrophy, which need to be judged by a specialist.
