Anxiety is a feeling of nervousness, worry, or uneasiness that we normally experience. It is also present in a wide range of mental disorders, including generalized anxiety disorder, panic disorder, and phobias. Although each of these conditions is different, they are all characterized by suffering and dysfunction specifically related to anxiety and fear.
So, What is anxiety?
Anxiety is a term widely used to indicate a complex of cognitive, behavioral and physiological reactions that manifest themselves following the perception of a stimulus considered threatening and to which we do not consider ourselves sufficiently capable of reacting.
In short, anxiety is a normal emotion, which we all experience and which, within certain limits, is extremely useful. It is not a useless and annoying burden, created to make our lives more difficult. Without anxiety we would not live more than a week and our species, by now, would have already become extinct.
It is a basic emotion, which involves a state of activation of the organism, when a situation is subjectively perceived as dangerous, to prepare it to react effectively.
Causes of Anxiety Disorders
The causes of anxiety disorders are not entirely known, but the following situations may be involved:
- ✅ Environmental stress or traumatic events;
- ✅ Genetic predisposition or family history of anxiety disorders;
- ✅ Medical conditions such as overactive thyroid or heart issues;
- ✅ Use of drugs or substances like caffeine, cocaine, or corticosteroids;
- ✅ Withdrawal from alcohol, sedatives, or other medications;
- ✅ Ongoing health fears or chronic illness;
- ✅ Stressful life changes such as relationship breakups or financial issues;
- ✅ Learned behaviors from living around anxious individuals;
- ✅ Hormonal imbalances;
- ✅ Neurological imbalances or brain chemistry changes.
An anxiety disorder can be triggered by environmental stressors, such as the breakup of an important relationship or exposure to a life-threatening disaster. However, many people develop an anxiety disorder without an identifiable trigger.
When a person responds intensely to stress or is overwhelmed by events, an anxiety disorder may develop. For example, some people have no problem speaking in front of an audience. Others are afraid of it, become anxious, and show symptoms such as sweating, fear, a racing heart, and shaking. These people are also afraid of speaking in a small group.
Anxiety tends to run in families, and doctors believe that some of the tendency may be inherited, but some of it probably comes from living around anxious people. So, did you know that:
- ✅ Anxiety disorders can be triggered by major life stressors like breakups or disasters;
- ✅ Many people develop anxiety disorders without a clear or known cause;
- ✅ Intense stress responses or overwhelming life events may lead to anxiety disorders;
- ✅ Public speaking can trigger anxiety in some, causing symptoms like sweating, shaking, and fear;
- ✅ Some individuals experience anxiety even in small social settings;
- ✅ Anxiety often runs in families, suggesting a genetic link;
- ✅ Living in an environment with anxious individuals can also contribute to anxiety development;
- ✅ Both nature (genetics) and nurture (environment) influence the risk of developing anxiety.
Anxiety caused by a medical condition or medication
Anxiety can be caused by a disease or by the use or suspension of a drug (withdrawal). The diseases that can induce anxiety are the following:
- ✅ Heart diseases such as heart failure and abnormal heart rhythms;
- ✅ Hormonal disorders like an overactive thyroid (hyperthyroidism) or adrenal gland issues;
- ✅ Lung conditions such as asthma, COPD (chronic obstructive pulmonary disease), and sleep apnea;
- ✅ Neurological disorders affecting the brain or nervous system;
- ✅ Chronic illnesses that cause long-term stress or discomfort;
- ✅ Painful medical conditions that impact daily life and well-being;
- ✅ Fever or infections that alter normal body functions;
- ✅ Withdrawal from drugs, especially sedatives or alcohol, can induce anxiety.
It is normal to have some level of anxiety when you have a medical condition that you fear will make you ill or even kill you. There is no level of anxiety that is considered reasonable or excessive for every individual or for every medical condition. However, if it causes you distress or interferes with your daily activities, you may have an anxiety disorder that needs to be treated. Fever can also cause anxiety. Narcotics, medications, or other substances that can cause anxiety include:
- ✅ Alcohol;
- ✅ Stimulants;
- ✅ Caffeine;
- ✅ Cannabis;
- ✅ Cocaine;
- ✅ MDMA;
- ✅ Many prescription medications, such as corticosteroids;
- ✅ Some over-the-counter medications, such as antihistamines and decongestants;
- ✅ Some over-the-counter weight loss products, such as those containing the herbal product guarana, caffeine, or both.
Withdrawal from alcohol or sedatives, such as benzodiazepines, can induce anxiety and other symptoms, such as insomnia and restlessness.
Many people have developed anxiety and disorders related to trauma and stressors during the COVID-19 pandemic, and some continue to have anxiety associated with the Corona Virus infection. Factors that have caused or aggravated fear and anxiety include the risk of illness or death, symptoms such as shortness of breath, treatment with corticosteroids, the illness or death of a loved one, the need for preventive measures, and many other personal or social factors.
Anxiety can also affect people with life-threatening illnesses, as a result of fear of dying, pain, and breathing difficulties.
Anxiety symptoms
When the state of anxiety tends to persist in the absence of an objective condition of danger, we are dealing with pathological anxiety or true anxiety disorders. In this case, the person experiences extremely annoying symptoms, sometimes sudden and persistent, of various natures.
1. Physical Symptoms of Anxiety
Anxiety is first of all characterized by physical and physiological manifestations, which usually create discomfort or are in turn perceived as threatening, such as:
❤️🩹 Understanding Palpitations and Their Link to Anxiety
Palpitations or other cardiac symptoms such as increased heart rate, arrhythmia, increased perception of the heartbeat itself. It is necessary, as far as possible, to distinguish different conditions related to palpitations: heart palpitations, tachycardia and arrhythmia. The latter, for example, often occurs with irregular heartbeats even in healthy people, during their daily activities and is more likely to occur when the person is anxious.
It can be induced by a series of agents such as nicotine, caffeine, alcohol and electrolyte imbalance. Often the interpretation given to this physical symptom during a state of anxiety is linked to the idea of having a heart attack. This is true even if the basis is an increased electrophysiological excitability of the cardiac muscle that has no negative consequences from a medical point of view.
💥 How Anxiety Triggers Chest Pain and Panic Attacks
Chest pain, a physical symptom that can occur during periods of high anxiety in the absence of a heart disorder. It can therefore derive from different sources such as chest breathing and gastrointestinal disorders. When the person catastrophically interprets the benign causes of pain, it is possible that the state of anxiety increases, even leading to panic.
In reality, we know that when a very high state of anxiety emerges, the body secretes adrenaline which causes an increase in the heartbeat and the body works faster. It is an evolutionary way to better prepare the person to manage dangerous situations. If adrenaline damaged the heart, how could man have survived until today? Therefore, the acceleration of the heartbeat due to anxious states does not cause heart attacks; there must be something pathological, for this to happen.
🌬️ Sensation of shortness of breath
Breathing is an action that works independently of what a person thinks or does, it is automatically controlled by the brain. In fact, brain controls work even when you try to stop breathing. The sensation of shortness of breath is very common in anxiety disorders and comes from prolonged and repeated thoracic breathing.
In fact, a physical response to stress is the relative dominance of thoracic breathing over abdominal breathing which leads to fatigue of the intercostal muscles, which strain and spasm causing discomfort and chest pain inducing the sensation of shortness of breath. If you fail to understand that these sensations are induced by thoracic breathing, then they will seem sudden, frightening, leading the person to become further alarmed.
🎢 The Connection Between Anxiety, Vertigo, and Dizziness
Vertigo and sensations of dizziness, of being dizzy, with altered spatial perception. Vertigo is the product of the illusion of movement of oneself or of the environment. It consists of sensations of confusion or dizziness, of vertigo or light-headedness. When the information coming from the balance system conflicts, vertigo occurs.
Balance problems and associated physical symptoms (instability, anxiety, cold sweat, palpitations) can also occur following anxiety, hyperventilation and common reactions to stress such as clenching the jaw and teeth. Obviously the intensity of vertigo can increase if more attention is paid to these sensations.
🤢 Understanding Nausea and Abdominal Discomfort in Anxiety
Nausea or abdominal discomfort, which can sometimes lead to sudden vomiting in the absence of gastrointestinal alterations or real digestive problems. The feeding and digestion functions are the first to stop during a state of alert, but if the person mistakenly interprets nausea as a sign of imminent vomiting, anxiety is more likely to increase and lead to panic. But, fortunately, that nausea leads to vomiting rarely happens, it is more likely that people overestimate this eventuality.
🌀 The Role of Sensory Deprivation in Dissociative Symptoms
Sensation of derealization (perceiving reality around you from an external perspective, as if you were watching a movie) and depersonalization (perceiving yourself from an external perspective) or other symptoms of a dissociative nature, with alteration of the state of consciousness. These are experiences that can be induced by tiredness, sleep deprivation, meditation, relaxation or the use of substances, alcohol.
There are also other more subtle causes linked to short periods of sensory deprivation or reduction of sensory input, such as staring at a point on a wall for 3 minutes. The more a person is scared, the more he breathes, the more he loads up with oxygen the more the feeling of depersonalization or derealization increases.
💪 How Muscle Tension Causes Headaches and Vision Changes
Diffuse muscle tension, especially in areas such as the neck, head (hence tension headache), eyeballs (with vision alterations), pelvic and genitourinary areas, gastrointestinal system; sometimes actual muscle fasciculations appear.
🤲 Recognizing Physical Signs: Trembling Hands and Legs from Anxiety
Sensation of trembling in the hands and/or legs, involuntary, oscillatory and rhythmic movements of one or more parts of the body, caused by the alternating contraction of opposite muscle movements. Chills in the absence of cold (similar to when a fever is rising), chattering of the teeth.
💧 How Anxiety Triggers Sweating Beyond Normal Body Temperature
Excessive sweating is not justified by the ambient temperature, as if the body were under stress. Sweating helps control body temperature, which rises when there have been anxious states. In fact, stress stimulates the sympathetic nervous system with increased levels of adrenaline and noradrenaline that stimulate an increase in metabolism, thus increasing heat production and the consequent sweating useful for lowering body temperature.

Call: (469)-868-62502. Cognitive Symptoms of Anxiety
From a cognitive point of view, the typical symptoms of anxiety are:
- ✅ Excessive worry or fear;
- ✅ Difficulty concentrating or focusing;
- ✅ Racing thoughts;
- ✅ Anticipating the worst-case scenario;
- ✅ Indecisiveness or overthinking decisions;
- ✅ Feelings of unreality or detachment;
- ✅ Heightened self-awareness or fear of losing control;
- ✅ Difficulty remembering things due to mental overload;
- ✅ Increasing sense of alarm and danger, as if something terrible was about to happen, for no good reason;
- ✅ Intrusive presence of negative or frightening images, memories and thoughts, which further fuel the anxious state;
- ✅ Marked feeling of being observed and being the center of attention of others.
3. Behavioral Symptoms of Anxiety
In humans, anxiety translates into an immediate tendency to explore the environment, in the search for explanations, reassurances and escape routes. The main instinctive strategy for managing anxiety is also the avoidance of the feared situation. Protective behaviors, unassertive behaviors and submissive behaviors are also frequent.
- ✅ Avoidance of feared situations;
- ✅ Protective behaviors to reduce anxiety;
- ✅ Unassertive behaviors in social settings;
- ✅ Submissive behaviors to avoid conflict;
- ✅ Increased seeking of reassurance or escape routes.
⚠️ The fear of fear
The physical symptoms of anxiety are often frightening, generating vicious circles, or the so-called “fear of fear”. However, they depend on the fact that, assuming one is in a situation of real danger, the anxious organism needs the maximum muscular energy available, to be able to escape or attack in the most effective way possible, avoiding the danger and ensuring survival.
Anxiety, therefore, is not only a limitation or a disorder, but it is an important resource. It is in fact a physiological condition that is effective in many moments of life to protect us from risks, maintain a state of alertness and improve performance.
However, when the activation of the anxiety system is excessive, unjustified or disproportionate to the situation, we are faced with an anxiety disorder, which can significantly complicate a person’s life and make them incapable of dealing with even the most common situations.
💊 Diagnosis of anxiety disorders
Determining whether anxiety is severe enough to be considered a medical condition is not easy. Patients’ ability to tolerate anxiety varies, and it can be difficult to determine the cause of the medical condition. Doctors typically use the following established criteria:
- ✅ Anxiety causes discomfort;
- ✅ Anxiety interferes with normal functioning;
- ✅ The anxiety is long-lasting or keeps recurring.
Doctors look for other disorders that can cause anxiety, such as depression disorder, or sleep disorders. They also ask whether family members have had similar symptoms, because anxiety disorders tend to run in families.
Doctors also perform a physical examination. Various tests, including blood tests, are also performed to check for other medical conditions that cause anxiety.
❤️ Treatment of anxiety disorders
- Treatment of the cause, if a pathology is found;
- Instruction;
- Relaxation techniques;
- Psychotherapy;
- Drugs.
It is important to make an accurate diagnosis, because treatment varies depending on the anxiety disorder. In addition, anxiety disorders must be distinguished from the anxiety that occurs in many other mental illnesses, for which other therapeutic approaches are adopted. If the cause of anxiety is a medical condition or medication, doctors treat the cause.
Anxiety should subside after treatment of the condition or stopping the medication long enough for any withdrawal symptoms to subside. If anxiety persists, anti-anxiety medications or psychotherapy are used.
Many people with anxiety disorders self-medicate with substances such as alcohol, marijuana, and benzodiazepines. Not only may they be embarrassed to admit this to their doctor, but they may also be unwilling to give up these substances until their doctor suggests a suitable alternative. Self-medicating in this way is dangerous and can lead to a vicious cycle of rebound anxiety after use, followed by an urgent need to self-medicate repeatedly.
If an anxiety disorder is diagnosed, medication or psychotherapy (such as cognitive behavioral therapy), alone or in combination, can significantly alleviate distress and discomfort in most patients. Different types of psychotherapy may be used, such as CBT, mindfulness-based stress reduction, hypnosis, and supportive psychotherapy.
Benzodiazepines (such as diazepam) are commonly prescribed. For many people, antidepressants, such as selective serotonin reuptake inhibitors (SSRIs), are as effective for anxiety disorders as they are for depression.
Wrapping Up: Effective Approaches to Anxiety Treatment
All anxiety disorders can occur with other mental illnesses. Doctors must treat all conditions related to anxiety. For example, anxiety disorders often occur with alcohol use disorder. Treating alcohol use disorder without treating anxiety will likely not be effective, since the person may use alcohol to reduce anxiety.
On the other hand, treating anxiety without addressing alcohol use disorder may be ineffective because daily changes in the amount of alcohol in the blood can cause fluctuations in anxiety levels.
