There is a difference between phytodystrophy and anxiety disorders. Phytodystrophy, also called autonomic dysfunction, is mainly manifested as a disruption of the balance of cardiac muscle, smooth muscle, visceral activity and glandular secretion innervated by the two major nervous systems, sympathetic and parasympathetic, resulting in clinical symptoms involving multiple systems throughout the body. Common symptoms include postural hypotension, dizziness, syncope, blurred vision, unsteady gait, fatigue and other symptoms. For the cardiovascular system, such as palpitations, chest tightness, and chest pain. Gastrointestinal disorders, such as abdominal distension, abdominal pain, nausea, vomiting, constipation, and loss of appetite. Urinary system, such as urinary frequency, urinary urgency, urinary retention, stress urinary incontinence. Reproductive system, such as decreased libido, erectile dysfunction in men, menstrual irregularities and dysmenorrhea in women. In addition, there are excessive or decreased sweating, numbness or tingling in the extremities, and mood changes such as anxiety and tension. Anxiety disorders are a group of mental disorders with anxiety syndromes as the main clinical manifestation. Anxiety syndromes manifest as mental symptoms and somatic symptoms. Psychiatric symptoms are internal experiences of worry, fear and apprehension, accompanied by nervousness and anxiety. Somatic symptoms are based on mental symptoms, accompanied by symptoms of autonomic nervous system hyperfunction, such as panic, chest tightness, shortness of breath, dry mouth, sweating, muscle tension tremor, trembling, flushing or pale face, etc. Patients with anxiety disorders are prone to autonomic dysfunction.
