Anyone experiencing stress will instinctively worry, but some people will become stressed and anxious day after day even though they have nothing to worry about at all. When this process continues for 6 months or more, then it may be a sign of Generalized Anxiety Disorder (GAD for short). This disorder affects the normal lives of close to 7 million people in the United States. Unfortunately, many people don’t even know they have the disorder and therefore can miss out on treatment that would otherwise improve their lives. Anxiety disorders are divided into generalized anxiety and panic attacks. The patient’s anxiety and panic are not caused by an actual threat or danger, or their level of nervousness and panic is not commensurate with the reality of the situation. Generalized anxiety: Excessive anxiety lasting more than six months; an anxiety disorder that is characterized by a lack of specific objects and content, and tension and anxiety, in which the patient is constantly on edge, concerned about his or her work and health, worried about the safety of loved ones, and fearful of unpredictable events, and does not seem to be directed at any specific single event; its occurrence does not seem to be precipitated. In fact, in some patients with generalized anxiety disorder, the mere thought of how to get through the day may trigger anxiety. The patient is distressed because it is unbearable and cannot be relieved. With vegetative hyperactivity: dry mouth, chest tightness, tachycardia, frequent urination, diarrhea, constipation, shivering and sweating, palpitations, dyspnea. Motor restlessness: hand trembling, muscle tension, restless walking back and forth. Increased alertness: Significant anxiety and vegetative hyperactivity in response to minor stimuli. Panic attacks: Panic attacks often occur suddenly, without prior aura, and are also generally not significantly related to life events or mental stimuli. Typically, they occur suddenly while the patient is engaged in daily activities such as reading, writing, eating, meeting, walking, working, or performing household chores. Patients often suddenly feel severe palpitations, as if the heart is about to spill out of the mouth; chest pain, suffocation, and a distinct feeling of pressure in the chest; difficulty breathing, throat blockage, and a sense of suffocation or near death; or they may manifest as hyperventilation. At the same time, there is a severe sense of fear, as if they are about to die or about to lose their senses; the patient feels very nervous and unbearable, while screaming and calling for help; some patients can also be accompanied by a sense of non-real, the experience of the disintegration of the human body Symptoms of overexcitation of the function of the autonomic nervous system: dizziness, excessive sweating, facial flushing or pallor, numbness in the hands and feet, gastrointestinal discomfort, etc. These attacks last for a short period of time, usually 5 to 20 minutes, rarely more than an hour, and then resolve on their own; or the attack may end with yawning, urination, or falling asleep. Anticipatory anxiety: The interictal period can be completely normal, but most patients often show anxiety for fear of having another attack, and some symptoms of autonomic hyperactivity can also be present. Avoidance behavior: Because panic attacks bring extreme terror to patients, 60% of patients actively avoid situations during the interictal period because they are afraid of not being able to get help during an attack, such as not wanting to go out alone, not wanting to go to crowded places or going out by car. Normal anxiety Anxiety is an emotional response that occurs when people are faced with potential or real danger or threat. The majority of understandable, moderate anxiety caused by certain reasons is normal anxiety.
