Anxiety Disorders

What is Anxiety?

Anxiety is a normal human emotion experienced by everyone to some extent. However, when anxiety becomes excessive, persistent, or begins to interfere with daily life, it can develop into an anxiety disorder.

Anxiety disorders are the most prevalent mental health disorders worldwide. According to the World Health Organization, approximately 264 million people globally suffer from an anxiety disorder. Anxiety disorders can affect anyone, regardless of age, gender, or socioeconomic status. They often co-occur with other mental health conditions, such as depression or substance use disorders.

Symptoms of Anxiety Disorders

Anxiety disorders can cause a broad range of physical, emotional, and cognitive symptoms that can significantly interfere with everyday life. These symptoms can vary depending on the specific disorder, but there are several common indicators across all types.

On a cognitive level, individuals with anxiety disorders often suffer from persistent, excessive, and uncontrollable worry about everyday situations. This can be incredibly distracting, making it difficult to concentrate and complete tasks. The fear and worry are usually disproportionate to the situation, leading to people overestimating the danger and underestimating their ability to cope. People often anticipate the worst, have racing thoughts, and find it difficult to be still and relaxed.

Emotionally, individuals may feel restless, tense, or on edge. They might experience a feeling of dread or impending doom, nervousness, and irritability. They may also become easily fatigued and have difficulty sleeping, including trouble falling asleep, waking up during the night, or experiencing restless and unsatisfying sleep.

Simultaneously, anxiety disorders often present several physical symptoms. These can include a faster heart rate, hyperventilation, dry mouth, dizziness, excessive sweating, trembling, and gastrointestinal problems like stomach upset or diarrhoea. People may experience muscle tension or headaches, as well as panic attacks, which are characterised by an intense feeling of fear and a range of physical symptoms such as chest pain, shortness of breath, nausea, and a fear of dying.

These symptoms can impede a person’s normal routine, social activities, or relationships. The severity and frequency of these symptoms can fluctuate, but whatever the level, it is important to seek professional help when these signs become evident consistently over time.

Common physical symptoms include:
- Persistent excessive worry or fear
- Irritability
- Restlessness
- Difficulty concentrating
- Sleep disturbances
- Fatigue
- Muscle tension
- Rapid heartbeat
- Shortness of breath
- Sweating

What Causes Anxiety Disorders?

Symptoms of anxiety

The exact cause of anxiety disorders isn't fully understood, but they are likely a result of a combination of factors. These can be divided into three broad categories: genetics, brain chemistry, and environmental factors.

Genetics play a crucial role in the development of anxiety disorders. Studies indicate that these disorders run in families, suggesting a strong genetic link. If a person has a close family member who suffers from an anxiety disorder, they are at a higher risk of developing a similar condition.

Neurochemical imbalance also contributes to anxiety disorders. These disorders have been associated with abnormal levels of certain neurotransmitters in the brain. Neurotransmitters are specialised chemicals that allow communication between nerve cells. When they are out of balance, messages cannot get through the brain properly, leading to the alteration of the way the brain reacts in certain situations, causing anxiety.

Environmental factors and life experiences are equally as crucial in the development of anxiety disorders. Traumatic experiences like abuse, victimisation, or exposure to combat may cause personality changes that predispose an individual to anxiety and related disorders. Similarly, long-term stress such as work, relationships, or financial problems can also lead to the development of these disorders.

It's also important to note that other medical conditions can simulate symptoms of anxiety disorders, including certain types of heart disease, hormonal disorders, and drug misuse or withdrawal. These factors don’t work independently and often interact with each other. For instance, a person may have inherited a genetic predisposition to anxiety and then a certain life event triggers the onset of the disorder. Hence, it's important to consider all these factors while diagnosing and treating anxiety disorders.

Contributing factors may include:
- Family history of anxiety or other mental health disorders
- Childhood trauma or abuse
- Chronic medical conditions or pain
- Substance use or withdrawal
- Hormonal imbalances
- Personality traits such as perfectionism or low self-esteem
- Stressful life events

Types of Anxiety Disorders

There are several types of anxiety disorders that individuals may experience.  Understanding the different types of anxiety disorders can help in identifying symptoms and providing appropriate treatment.

Generalised Anxiety Disorder (GAD)
One common type is generalised anxiety disorder, characterised by excessive worry and fear about everyday events. This condition can be chronic and may interfere with daily functioning.

Panic Disorder
Panic disorder is another anxiety disorder characterised by recurring panic attacks. People with anxiety disorders can experience episodes of unexpected sudden intense fear causing panic attacks characterised by chest pain, sweat, and heart palpitations (which can feel like a heart attack).

Social Anxiety Disorder (aka Social Phobia)
Another type is social anxiety disorder, where individuals have an intense fear of social situations and feel extreme self-consciousness. They are often afraid of being judged or embarrassed in front of others.

Phobia-related disorders
Phobias can cause anxiety symptoms, where individuals have a strong fear of a specific object or situation. This fear can be irrational and lead to avoidance behaviour. The intense and excessive fear and avoidance of objects or feeling like they need to avoid situations can result in an impact on quality of life such as arachnophobia (fear of spiders), phidiophobia (fear of snakes), glossophobia (fear of public speaking), and acrophobia (fear of heights).

Intense and excessive fear of being in a place when it is hard to escape in case of emergency, such as:
- Open spaces
- Closed spaces
- Outside of the home (particularly when alone)
- In a crowd
- Public transport
- Standing in a line

Separation Anxiety Disorder
Separation anxiety disorder is common in children and occurs when they have an excessive fear of being separated from their primary caregivers. Intense anxiety and excessive fear of being away from a person to whom the person is attached (more common in childhood but also can occur in adulthood).

Selective Mutism
More common in young children, this is a rare anxiety disorder that often co-occurs with other anxiety disorders and involves the inability to speak in specific social situations due to severe anxiety (not speech difficulties).

Medication-Induced Anxiety Disorder
Intense and excessive anxiety triggered by the use of or withdrawal from drugs (both prescribed and non-prescribed). Anxiety may be exacerbated by medication.

Obsessive-Compulsive Disorder
Lastly, obsessive-compulsive disorder is an anxiety disorder characterised by obsessive thoughts and compulsive behaviours that individuals feel compelled to repeat.

Treatment Options for Anxiety Disorders


Treatment for anxiety disorders is typically a combination of psychotherapy, medication, and self-help strategies. Some evidence-based treatment options include:

Cognitive Behavioural Therapy (CBT): This form of therapy helps individuals identify and change negative thoughts patterns and behaviours that contribute to anxiety.

Exposure Therapy: This technique involves gradually confronting feared situations or objects while learning to manage the anxiety response.

Medications: Antidepressants, such as selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitors (SNRIs), are commonly prescribed for anxiety disorders. Benzodiazepines may be prescribed for short-term relief of severe anxiety.

Relaxation and Mindfulness Techniques: Deep breathing, progressive muscle relaxation, and mindfulness meditation can help manage anxiety symptoms.

Lifestyle Changes: Regular exercise (if adequately nourished), a balanced diet, and sufficient sleep can improve overall mental health and reduce anxiety.

Tips for Managing Anxiety

Managing anxiety can be a continuous process that involves lifestyle changes, cognitive behavioural strategies, and in some cases, professional healthcare. Here are some tips to help manage anxiety:

1. Practice Mindful Relaxation: Incorporating relaxation techniques into your daily routine can help manage anxiety. Mindfulness, meditation, progressive muscle relaxation, and deep breathing exercises can reduce feelings of anxiety by slowing down your thoughts and relaxing your body.

2. Maintain a Balanced Diet and Physical Activity: A healthy, balanced diet rich in fresh fruits, vegetables, lean proteins, and whole grains can affect your mood and energy levels. Regular physical activity also plays a key role in managing anxiety. Exercise helps increase the production of your brain's feel-good neurotransmitters, the endorphins.

3. Limit Alcohol and Avoid Drugs: These substances can trigger or exacerbate anxiety and can also interfere with the effectiveness of prescribed medication.

4. Get Enough Sleep: Lack of adequate sleep can exacerbate anxiety. Aim for 7-9 hours of quality sleep a night. Develop a regular sleep routine and create a quiet, dark environment in your bedroom.

5. Limit Caffeine Intake: Foods and drinks containing caffeine can trigger or worsen anxiety symptoms. Consider decreasing your caffeine intake or cutting it out entirely if you notice it causes you to feel jittery or anxious.

6. Stay Connected: Social interaction and support can both distract you from your worries and provide you with a sense of being understood and valued. It can help to talk about your anxiety with trusted friends, family members, or a support group.

7. Practice Cognitive Strategies: Learning to recognize and alter thought patterns that lead to anxiety can be beneficial. This is often a part of cognitive-behavioural therapy (CBT), a type of psychotherapy that can be highly effective for anxiety disorders.

Remember, if at any point you feel overwhelmed by anxiety, it may be necessary to seek professional help. Mental health professionals can provide additional strategies and treatments such as medication, therapy, and more.

Do I have an anxiety condition?

Anxiety is a normal emotion that we all experience from time to time, particularly when faced with stressful situations such as an interview or an examination. However, when feelings of worry and fear become chronic, overwhelming, and out of proportion to the actual stress in your life, it could point to an Anxiety Disorder. Anxiety Disorders are a group of mental health conditions that are characterized by constant and unnecessary worry about everyday situations. The most common types include Generalised Anxiety Disorder, Panic Disorder, Phobia-related Disorders, and Social Anxiety Disorder.

Determining if you have an anxiety disorder is not always straightforward as symptoms can vary from person to person. However, there are common signs that medical professionals use to identify these conditions. If you often feel restless or on-edge, easily fatigued, irritable, or plagued by uncontrollable feelings of worry, it might be indicative of an anxiety disorder. Additionally, if you find yourself avoiding situations that make you anxious or often anticipate the worst-case scenario, these can also be symptomatic. Diagnosis requires a thorough evaluation by a trained professional such as a psychiatrist or psychologist, who would use clinical interviews, psychological testing, and the diagnosis criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition. These criteria include excessive fear or anxiety for at least six months, the inability to control worrying, and at least three physical or cognitive symptoms of anxiety. It's crucial to know that there are effective treatments available, including a combination of psychotherapy, behaviour therapy, and in some cases, medication. Prompt diagnosis and treatment can improve quality of life and reduce the risk of other health conditions, such as depression or substance abuse.

Related Conditions

Anxiety disorders are often not standalone mental health conditions and can frequently co-occur with other disorders. These comorbid conditions can sometimes be a consequence of living with intense, persistent anxiety, while at other times, anxiety and these disorders may be symptoms of an underlying mental health issue. Understanding the related conditions can offer a more comprehensive view of managing anxiety disorders.

Depression is one of the most common conditions to co-occur with anxiety. Major Depressive Disorder (MDD) is characterised by persistent feelings of sadness, hopelessness, and a lack of interest or pleasure in activities. People with MDD may also experience weight changes, fatigue, difficulty concentrating, or suicidal thoughts. Similarly, Bipolar Disorder is also regularly associated with anxiety disorders. Also, Substance Use Disorders (SUDs), such as alcohol or drug dependence, are more common in those with anxiety disorders, possibly indicating a reliance on these substances as a misplaced coping strategy.

There is a strong link between anxiety disorders and physical health conditions as well. For instance, individuals with chronic conditions such as cardiovascular disease, diabetes, and chronic respiratory disorders often struggle with anxiety, underlining the connection between physical and mental health. It's important to remember that effective treatment for anxiety in individuals with these comorbid conditions often requires an integrated approach. This approach should address the anxiety disorder while also considering the diagnosis and treatment of the related conditions. The goal is to help individuals develop strategies to manage all aspects of their health effectively.

Supporting someone else

Supporting someone with an anxiety disorder can be a challenging but vital role. It can make a significant positive impact on their ability to manage the condition, and provide them with a feeling of comfort and safety. Understanding the nature of the disorder is the first step. Anxiety isn't something a person chooses to have; it is a real and serious mental health condition that involves intense feelings of worry, fear or anxiety that are strong enough to interfere with one's daily activities.

One way to support a loved one with anxiety is through patience and understanding. Since anxiety manifests differently in people, acknowledge their feelings, lend a listening ear, and avoid making judgmental comments. Apply a compassionate but strong approach to support them during their anxious periods. It's essential to be a source of comfort, not more stress. This might involve being with them during uncomfortable situations or reassuring them during an anxiety attack. It also means avoiding forceful encouragement to face their fears as it may lead to more anxiety.

Encouraging them to seek professional help should also be a high priority. Professional psychologists, psychiatrists or therapists are specialised to deliver cognitive-behavioural therapy, conduct exposure therapy sessions or prescribe medications when necessary. For some people, joining a support group can also be beneficial. And remember, while taking care of someone else, it's important not to forget about your own mental health. Balancing the two and seeking help when needed can make your support journey more sustainable and effective.

When to get professional help

Recognising when to seek professional medical help for anxiety can be vital for managing symptoms and improving quality of life. Anxiety, as a temporary response to stress, isn't a cause for concern. However, if feelings of anxiety persist for more than six months and start to interfere with daily activities, it's time to reach out to a medical professional. Excessive persistent worrying, fear, agitation, restlessness, fatigue, difficulty sleeping, panic attacks, and avoidance behaviours are all potential signs of an anxiety disorder that requires professional attention.

In addition to the chronicity and severity of symptoms, numerous other situations may necessitate a visit to the doctor. These include if you have a history of traumatic experiences, have had a recent major life change, using alcohol or drugs to cope with anxiety or have suicidal thoughts or behaviours. Furthermore, if you have other mental health conditions, or physical health conditions, such as heart disease, diabetes, or thyroid problems, it's particularly important to discuss your anxiety symptoms with your doctor, as these could be interconnected.

When seeking help, you can start with your primary care provider, who may then refer you to a mental health professional, like a psychiatrist or psychologist. These specialists can provide an official diagnosis, offer treatment options, and guide you through managing the condition. Remember, seeking help is not a sign of weakness, but a crucial step to regain control of your life and improve overall well-being.
