Anxiety
Also known as Anxiety disorder.Overview
Anxiety refers to a feeling of stress, worry, or nervousness as a reaction to difficult and stressful situations. Some feelings of being anxious are completely natural; they even help you become productive in dealing with challenging situations. However, a feeling of intense fear, worry, and panic about day-to-day situations that interfere with your daily life and surroundings to a great extent is a psychiatric condition called anxiety disorder.
A rapid heartbeat, sweating, fatigue, irritability, feeling of dread, racing thoughts, and difficulty concentrating are some of the symptoms of anxiety. Factors like a family history of anxiety, childhood adversity, substance misuse, chronic illness, or high-stress environments can increase the risk. Anxiety disorders are the most common types of mental health conditions and are twice as likely to affect females as males.
If episodes of anxiety become too frequent and severe, and start affecting your quality of life and everyday behavior, it is essential to seek professional help. Medications, psychotherapy, and lifestyle modifications can help alleviate the symptoms of anxiety.

Types Of Anxiety
According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), anxiety disorders are classified as:
1. Generalized anxiety disorder (GAD)
GAD is characterized by excessive and persistent worry about various aspects of life, like work, health, and social interactions, for at least six months.
2. Panic disorder
Panic disorder involves recurrent, unexpected panic attacks, sudden periods of intense fear that peak within minutes.
3. Phobias
Phobias are intense, irrational fears of specific objects or situations that lead to avoidance behavior. There are three DSM-5 subtypes:
-
Specific phobias, like the fear of heights, blood, animals, etc.
-
Social anxiety disorder (social phobia), which is the fear of social situations
-
Agoraphobia is the fear of situations where escape might be difficult, for example a public transport, crowds, etc.

Causes Of Anxiety
Our brain produces certain chemicals which are known as neurotransmitters, which help us deal with anxiety. The neurotransmitters such as norepinephrine, serotonin, dopamine, and gamma-aminobutyric acid are related to our mood and emotions. Any imbalance of these neurotransmitters can lead to symptoms of anxiety and other anxiety-related disorders.
The causes of anxiety disorder are not very clear. Some people experience severe anxiety in certain situations, while others take similar conditions with ease. More focused studies are required to fully understand the reason. However, it is thought to be due to a complex interaction of genetics, environmental factors, and lifestyle choices.
We'll explore the risk factors in greater detail in the next section.
Risk Factors Of Anxiety
While anyone can experience anxiety, several factors are known to increase the likelihood of developing an anxiety disorder. These include:
Family history
Individuals with a parent or sibling diagnosed with an anxiety disorder are at increased risk, due to genetic and environmental factors.
Adverse childhood experiences
Early-life trauma, including emotional, physical, or sexual abuse or neglect, can alter stress regulation systems, increasing anxiety risk.
Traumatic life events
The sudden loss of a loved one, accidents, assaults, or exposure to violence are strong risk factors for the development of anxiety disorders.
Substance use
Alcohol, nicotine, and drug use, as well as withdrawal, can contribute to anxiety onset or exacerbate existing anxiety.
Mental health conditions
- Depression
- Post-traumatic stress disorder (PTSD)
- Obsessive-compulsive disorder (OCD)
Chronic medical conditions
- Diabetes
- Cardiovascular disease
- Chronic pain
- Thyroid disorders.
Women are nearly twice as likely as men to experience depression and anxiety disorders in their lifetime.

Diagnosis Of Anxiety
The diagnosis of an anxiety disorder is primarily clinical, based on a detailed evaluation of the person’s symptoms, medical and psychiatric history, and how these symptoms affect their daily functioning.
A mental health professional or primary care provider will often use structured interviews and standardized screening tools to assess the presence and severity of anxiety. Commonly used tools include:
-
GAD-7 (Generalized Anxiety Disorder-7): This is a short 7-question quiz used to check how often you feel worried, nervous, or restless.
-
Hamilton Anxiety Rating Scale (HAM-A): This is a checklist used by doctors to measure how severe your anxiety symptoms are.
-
Beck Anxiety Inventory (BAI): This consists of a 21-question self-test that helps you understand how much anxiety is affecting your body and mind.
There are no lab tests that can directly diagnose anxiety. However, to rule out medical conditions that can mimic or worsen anxiety symptoms, a physician may order:
-
Complete blood count: Done to look for signs of an infection or inflammation in the body
-
Thyroid profile total: This test is done to rule out any potential cause of thyroid disorders
-
Alcohol screen blood: This is a blood test to rule out symptoms caused due to alcohol abuse
-
Drugs of abuse (qualitative) panel: This has a series of blood tests to check if there are any underlying side effects of medicines
-
Electrocardiogram (ECG): This is an imaging test to rule out cardiac causes of palpitations or chest discomfort.
Booking lab tests has never been easier. Get tested with Tata 1mg for accurate and timely results.

Treatment Of Anxiety
Mild or infrequent episodes of anxiety do not require any treatment. However, when the episodes of anxiety or panic attacks become too frequent, then treatment is considered. It consists of:
Pharmacological management
a) Selective Serotonin Reuptake Inhibitors (SSRIs): These are used as first-line treatment for long-term management of anxiety disorders by increasing serotonin levels. Commonly used drugs are:
- Sertraline
- Paroxetine
- Escitalopram
b) Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs): These help relieve anxiety by increasing both serotonin and norepinephrine in the brain. Most commonly used medications are:
c) Benzodiazepines: These provide quick relief from acute anxiety symptoms but are not advised for long-term use due to the risk of dependence. Examples include:
d) Beta-blockers: Propranolol is commonly used to ease physical symptoms of anxiety, but evidence supporting its effectiveness for treating anxiety disorders is limited.

Psychological treatments(psychotherapy)
a) Cognitive Behavioral Therapy (CBT): CBT helps individuals identify and challenge negative thought patterns and behaviors, teaching healthier ways to cope with anxiety. It’s widely proven effective for many anxiety disorders.
b) Exposure-based therapies: These gradually expose individuals to feared situations or thoughts in a controlled way, helping reduce avoidance and fear over time. Highly effective for phobias, OCD, and panic-related disorders.
c) Mindfulness-based interventions: These use techniques like meditation and breathing exercises to focus on the present moment, helping reduce anxiety and emotional reactivity. They show moderate benefits, especially for stress-related anxiety.
Home-Care For Anxiety
Lifestyle changes like regular exercise, a balanced diet, good sleep, and limiting caffeine or alcohol can significantly reduce anxiety over time. If you experience extreme symptoms of anxiety, it might be a panic attack. Try this:
Grounding technique for anxiety attacks
If you are having a panic or anxiety attack, you can use a 5-4-3-2-1 technique to deal with anxiety. As per this technique, whenever you are feeling anxious, you should start concentrating on your breathing and try to take slow and deep, regular breaths. Once your breathing is normalized, follow the 5-4-3-2-1 steps:
- Identify 5 things you can see around you
- Identify 4 things you can touch around you
- Identify 3 things you can hear
- Identify 2 things you can smell
- Identify 1 thing you can taste
This will help distract your mind away from the anxious thoughts and help you cope with the anxiety attack.
Certain herbal supplements like passionflower and kava have shown strong evidence in reducing anxiety symptoms in some clinical studies. Always consult your doctor before starting any herbal remedy, especially if you're taking medications or have health conditions.
