Anxiety is an unpleasant emotional response to an adverse environment. To a certain extent, anxiety is a “protective reaction” because it forces people to develop the subjective will to escape or get rid of the bad environment. It is impossible for anyone to have a smooth life, so everyone will have different levels of anxiety. Under normal circumstances, people can have different emotional reactions to the environment or matters they are exposed to, such as students who cannot eat or sleep well before entrance exams, or athletes who get chills on their limbs, sweaty palms, and rapid heartbeat before a competition. As the situation improves, the symptoms will slowly disappear and the emotions will stabilize, which cannot be considered a disease. It can only be considered a disease for people for whom very small setbacks that occur in everyday life cause strong emotional reactions. In clinical practice, we call a group of symptoms centered on severe anxiety caused by a very minor cause “anxiety disorder”. According to modern psychology, anxiety disorders belong to the category of moderate mental ill health. As society develops and competition becomes more intense, the number of people suffering from anxiety disorders is increasing. The prevalence rate in Western countries is 3-5%, and the proportion of patients in China has gradually increased to 2-3%, especially in groups with mainly mental work, such as scientific research, teaching, institutions, management and other occupations, the number of patients is higher than that of manual workers, so it is necessary to pay attention to this part of the population. Clinical manifestations Anxiety disorders occur mostly in young and middle-aged people, and the triggering factors are mainly related to the personality and environment of the person. The former is mostly seen in those who are introverted, shy, and overly neurotic, while the latter is often closely related to fierce competition, overload, long-term mental work, and interpersonal tension. Some patients have atypical triggers. Clinically, physicians often divide anxiety disorders into two categories: acute anxiety and chronic anxiety. 1. Acute anxiety: also called “panic disorder”. The main manifestation is panic-like attacks, which occur more often at night during sleep, with the feeling of near death. The patient’s heart beats violently, the chest is stuffy, and there is a feeling of blockage in the throat and difficulty in breathing. Hyperventilation caused by panic leads to respiratory alkalosis (excessive exhalation of carbon dioxide leading to alkaline blood), which in turn induces numbness in the limbs, tingling around the mouth, pallor, and abdominal cramps, further aggravating the patient’s fear and causing a mental breakdown. These patients are often emotional and nervous when they visit the doctor, often giving the physician the illusion of a cardiovascular disease attack. Generally, acute anxiety attacks last for a few minutes or hours, and when the attack is over or after appropriate treatment, the symptoms can be relieved or disappear. 2.Chronic anxiety: also called “generalized anxiety”. Acute anxiety often arises on the background of chronic anxiety, but more patients mainly show the symptoms of chronic anxiety. The typical symptoms of chronic anxiety are five major symptoms, namely panic, fatigue, nervousness, shortness of breath and chest pain. In addition, there are tension, cold sweat, fainting, belching, nausea, abdominal distension, constipation, impotence, and urinary frequency and urgency, etc. Sometimes it is difficult to distinguish them from neurasthenia or other specialized diseases, so a physician needs to have a comprehensive and detailed understanding of the condition to avoid misdiagnosis. Sometimes some necessary auxiliary tests can help to exclude organic diseases, such as electrocardiogram, X-ray chest film, gastrointestinal imaging, gastroscopy, etc. can help physicians to detect diseases. However, although the subjective symptoms of anxiety disorders are severe, the objective signs are very mild or negative. Prevention and Treatment of Anxiety Disorders Having anxiety disorders is a painful thing that affects one’s life and work, and can cause tension in relationships with colleagues around you. However, it should be recognized that anxiety is an emotional expression that normal people also have, and only when it develops to a certain degree does the pathology appear. Therefore, the right to learn to temperament, regulate emotions, you can effectively prevent the occurrence of disease. Especially for those adolescents who are impatient and introverted, they should constantly overcome their weaknesses in character and learn to get along with their colleagues around them; improve their ability to deal with complex things, and being calm and unperturbed in the world is an effective means to prevent anxiety from arising. 1.Psychotherapy: Under the guidance of a psychiatrist, fully understand the causes and background of anxiety disorders and learn to transfer or dissolve mental stress. Through the exchange of ideas with relatives and friends, or adjust the life of the day off, can also largely reduce the mental burden and anxiety. 2.Dietary treatment: Patients suffering from anxiety disorders should pay attention to their diet. Generally speaking, for patients with gastrointestinal symptoms, they should arrange their lives rationally and prevent overeating or irregular eating to avoid increasing the burden on the gastrointestinal tract and aggravating their symptoms. For patients with heart symptoms, they should stay away from stimulating tobacco, alcohol, strong tea, coffee, spicy food, etc., because they can cause sympathetic excitement, rapid heartbeat, premature heartbeat, etc., making the existing symptoms more prominent. It is recommended to take light, easy-to-digest food and not to rest immediately after eating. For those who are bloated and constipated, you can also take drugs to help digestion and laxative. 3.Medication: It is the main means of treating anxiety disorders, and if used in combination with the above methods, it can often control the symptoms and shorten the course of treatment. In the clinic commonly used drugs are anti-anxiety drugs, they mainly act on the central nervous system of the limbic system, thalamus, amygdala and other parts, can significantly improve mood, anti-anxiety, such as benzodiazepines (diazepam, clonazepam, Jiajing Valium, Lola, etc.), or Enox, Sellett, Zoloft and other antidepressants. However, most of these drugs have certain side effects or addictive properties, and need to be used under the guidance of a physician and should not be taken indiscriminately. In addition, you can also add some other drugs for different system prominent symptoms, such as heartburn can be added to the use of insulin, betalac, etc.; indigestion can be used multi-enzyme tablets, morpholine, etc..
