Persistent, hard-to-control worry about everyday matters such as health, work, or family.

Feeling on edge or unable to relax.
Difficulty Concentrating
Trouble focusing on tasks due to persistent worry.
Physical Tension
Muscle tension, headaches, or general physical discomfort linked to anxiety.
Danger Signs
Seek urgent medical attention if any of the following occur.
Panic Attack Symptoms
Sudden chest pain, rapid heartbeat, or a feeling of impending doom can resemble a heart attack and needs urgent evaluation.
Difficulty Breathing
Severe shortness of breath during intense anxiety should be assessed to rule out other causes.
Thoughts of Self-harm
Any thoughts of self-harm require immediate help from a healthcare provider or emergency services.
Complete Avoidance of Daily Life
Avoiding work, school, or leaving the house entirely due to anxiety needs prompt professional support.
Diagnosis
Clinical Assessment
Diagnosis is based on a detailed conversation about the pattern, triggers, and impact of anxiety symptoms.
Screening Questionnaires
Standardized questionnaires help identify the type and severity of anxiety.
Physical Evaluation
Tests may be used to rule out physical conditions, such as thyroid problems, that can cause anxiety-like symptoms.
Laboratory Tests
Thyroid Function Tests
Rules out an overactive thyroid, which can cause symptoms that resemble anxiety.
Electrocardiogram (ECG)
May be used during panic-like symptoms to rule out a heart-related cause.
Complete Blood Count (CBC)
Helps rule out other medical conditions that could contribute to anxiety symptoms.
Treatment
Psychological Treatment (Talk Therapy)
Cognitive behavioural therapy is one of the most effective treatments for anxiety disorders.
Medication
Certain medications can help reduce anxiety symptoms, particularly when combined with psychological treatment.
Prevention
Learn stress management techniques
Relaxation techniques and healthy coping strategies can reduce the risk of developing an anxiety disorder.
Limit caffeine and stimulant use
Reducing caffeine and other stimulants can help prevent symptoms from worsening.
Maintain regular sleep habits
Consistent, adequate sleep supports emotional regulation and lowers anxiety risk.
Build a strong support network
Having supportive relationships helps buffer against stress and anxiety.
Risk Factors
High Risk
These factors substantially increase the likelihood of developing an anxiety disorder.
- History of abuse or severe losses
- Family history of anxiety disorders
- Other adverse life experiences
Increased Risk
These factors are associated with a moderately higher risk of anxiety disorders.
- Chronic physical illness
- High-stress environments
- Harmful use of alcohol
Additional Contributing Factors
Other factors linked with an increased likelihood of anxiety disorders.
- Female sex
- Certain personality traits, such as being prone to worry
- Significant life transitions
Complications
Depression
Anxiety disorders frequently occur alongside depression, complicating treatment and recovery.
Cardiovascular Disease
Physical effects of chronic anxiety, such as nervous system hyperactivity, are linked to a higher risk of cardiovascular disease.
Substance Use
Some people use alcohol or drugs to cope with anxiety, which can lead to substance use problems.
When to Seek Medical Care
Panic Attack Symptoms
Sudden chest pain or a racing heart during intense anxiety should be evaluated to rule out a medical emergency.
Thoughts of Self-harm
Seek immediate help from a healthcare provider, a trusted person, or emergency and crisis services.
Avoidance Affecting Daily Life
Avoiding work, school, or social situations due to anxiety is a sign that professional support is needed.
Symptoms Not Improving with Treatment
Anxiety that does not improve, or that worsens, despite treatment should be discussed with a healthcare provider.
Prognosis
Good with Appropriate Treatment
Most people with anxiety disorders see significant improvement with psychological treatment, medication, or both.
Often Chronic Without Treatment
Anxiety disorders can persist or worsen over time if left untreated.
Improved Outcomes with Early Care
Seeking treatment early is associated with better long-term outcomes and reduced impact on daily life.
Differential Diagnosis
Hyperthyroidism
An overactive thyroid can cause symptoms such as rapid heartbeat and restlessness that resemble anxiety.
Heart Disease
Can cause chest pain and palpitations that may be mistaken for a panic attack.
Depression
Shares overlapping symptoms with anxiety, such as sleep difficulty and poor concentration, and often occurs together with it.
Substance Use or Withdrawal
Caffeine, certain drugs, or withdrawal from substances such as alcohol can cause anxiety-like symptoms.
