Anxiety is a normal human emotion. Everyone feels nervous or uneasy from time to time—before an exam, during stressful situations, or when facing uncertainty. However, when anxiety becomes persistent, overwhelming, or difficult to control, it may be classified as an anxiety disorder. This can interfere with daily life, work, relationships, and overall well-being.
This article provides a medically accurate, easy-to-understand explanation of anxiety, its symptoms, causes, and evidence-based treatment approaches. It is written to support individuals seeking reliable mental health information in Bangkok or anywhere in the world.
What Is Anxiety?
Anxiety is the body’s natural response to stress. It activates the “fight-or-flight” system, preparing you to deal with danger. But when this response is triggered too often—or without a real threat—it can create constant worry, physical tension, and emotional discomfort.
Anxiety disorders occur when:
-
Anxiety is excessive
-
Anxiety lasts for weeks or months
-
Anxiety affects daily functioning
-
Physical symptoms appear without a clear medical cause
Anxiety disorders are among the most common mental health conditions and are highly treatable.
Common Symptoms of Anxiety
Symptoms of anxiety vary, but they typically include emotional, physical, and cognitive components.
Emotional Symptoms
-
Excessive worrying
-
Restlessness or feeling “on edge”
-
Irritability

Difficulty relaxing

Feeling overwhelmed easily
Physical Symptoms
-
Rapid heartbeat

What Causes Anxiety?
Anxiety arises from a combination of biological, psychological, and external factors.
Biological Factors
-
Genetics
-
Neurochemical imbalance
-
Hormonal changes
-
Thyroid disorders
-
Vitamin deficiencies (B12, D)
-
Effects of caffeine or stimulants
Psychological Factors

Negative thinking patterns
Environmental Contributors

When Anxiety Becomes a Concern
You may consider seeking medical or psychological support if:
-
Worrying is constant or uncontrollable
-
Anxiety interferes with sleep
-
You avoid situations out of fear
-
Symptoms affect your work or studies
-
Anxiety causes physical discomfort
-
Panic attacks occur
-
You experience irritability or emotional exhaustion
-
Anxiety persists for more than several weeks
Persistent anxiety is not simply “stress” or “overthinking.” It is a condition that benefits from proper evaluation.
How Anxiety Is Diagnosed
Diagnosis involves understanding both physical and emotional factors.
1. GP Consultation
A general practitioner helps rule out medical causes such as:
-
Thyroid dysfunction
-
Hormonal imbalance
-
Medication side effects
-
Vitamin deficiencies
This step is important because physical symptoms can closely mimic anxiety.
2. Mental Health Screening
Tools and questionnaires identify:
-
Severity of symptoms
-
Frequency
-
Emotional triggers
-
Functional impact
3. Psychiatry Evaluation
A psychiatrist can:
-
Confirm diagnosis
-
Differentiate between anxiety, panic disorder, burnout, or depression
-
Recommend treatment options
At MedConsult Clinic, many patients start with a GP consultation and, when appropriate, continue with a mental health / psychiatry consultation with Dr. Pui, along with counselling or follow-up support.
Evidence-Based Treatments for Anxiety
There are several effective treatment options depending on severity and root causes.
1. Psychological Therapy
Cognitive Behavioural Therapy (CBT) is one of the most effective treatments. It helps patients:
-
Identify thought patterns that fuel anxiety
-
Build coping skills
-
Reduce avoidance behaviours
-
Regain emotional control
Other therapy modalities such as mindfulness-based therapy, acceptance & commitment therapy (ACT), or supportive counselling may also be helpful.
2. Medication (When Recommended)
A psychiatrist may prescribe medication when:
-
Anxiety is moderate to severe
-
Therapy alone is insufficient
-
Anxiety is accompanied by depression or panic attacks
-
Symptoms affect daily life significantly
Medication is not always necessary but can be highly effective for some individuals.
3. Lifestyle Adjustments
Supportive strategies include:
-
Regular exercise
-
Consistent sleep schedule
-
Limiting caffeine and alcohol
-
Balanced nutrition
-
Practising relaxation techniques
-
Breathwork and grounding exercises
4. Addressing Medical Contributors
Treating conditions such as thyroid dysfunction, anemia, and vitamin deficiencies can reduce anxiety-like symptoms.
Anxiety vs. Stress – What’s the Difference?
Although the two feel similar, they are not the same.
Stress:
-
Triggered by external pressure
-
Usually temporary
-
Improves once the situation resolves
Anxiety:
-
Can persist without a clear reason
-
Continues even after stress is removed
-
Affects physical and emotional functioning
If symptoms remain longer than expected, an evaluation may be beneficial.
Living With Anxiety
Anxiety can be challenging, but many people manage it successfully with the right tools and support. Important points to remember:
-
Anxiety is common and treatable
-
You are not alone
-
Small improvements add up over time
-
Therapy and lifestyle changes can make a significant difference
-
Identifying triggers helps prevent episodes
-
Recovery is possible even after years of symptoms
