Panic Attacks
Sudden episodes of intense fear with physical symptoms like racing heart.
TL;DR
Panic attacks peak within ten minutes and are physiologically harmless despite feeling catastrophic. Avoidance is what turns isolated attacks into panic disorder — CBT with interoceptive exposure is the treatment that works.
Overview
A panic attack is an abrupt surge of intense fear reaching peak intensity within about ten minutes, accompanied by palpitations, chest tightness, breathlessness, dizziness, sweating, trembling, tingling in the hands and face, and a conviction of impending death or loss of control. The physiology is a full sympathetic discharge, and while it feels dangerous, it is not: the symptoms are the same ones exercise produces, occurring without warning and interpreted as catastrophe. Hyperventilation explains much of the symptom cluster, since blowing off carbon dioxide causes cerebral vasoconstriction, lightheadedness and perioral tingling, which then fuel further alarm. That feedback loop, rather than the attack itself, is the real target. The critical clinical point is what happens afterwards. Most people have an isolated attack and move on. Panic disorder develops when fear of the next attack drives avoidance of places and sensations, progressively narrowing life and sometimes producing agoraphobia. Cognitive behavioural therapy with interoceptive exposure — deliberately inducing the feared sensations through hyperventilation, spinning or breath-holding until they lose their threat value — has strong evidence and outperforms medication for durability. First attacks do warrant medical assessment, since thyroid disease, arrhythmia, hypoglycaemia, phaeochromocytoma and stimulant or caffeine effects all mimic panic. Supplements have limited data; magnesium and inositol have small trials, and kava carries hepatotoxicity concerns.
Common Symptoms
- •Sudden pounding heart
- •Chest tightness and breathlessness
- •Dizziness or unsteadiness
- •Tingling in hands and around the mouth
- •Sweating and trembling
- •Feeling detached or unreal
- •Fear of dying or losing control
Common Causes
- •Catastrophic misinterpretation of bodily sensations
- •Hyperventilation
- •Caffeine and stimulants
- •Alcohol withdrawal
- •Hyperthyroidism
- •Chronic stress or trauma
- •Arrhythmia mimicking panic
Root Causes
Heightened interoceptive sensitivity and catastrophic misinterpretation of bodily sensations, locus coeruleus and amygdala hyperreactivity, hyperventilation-induced hypocapnia, genetic vulnerability, caffeine and stimulant use, alcohol withdrawal, thyroid dysfunction, and prior trauma or chronic stress.
How It's Diagnosed
Diagnostic Markers
- Clinical history and symptom timing
- ECG and cardiac assessment after a first attack
- Thyroid function tests
- Fasting glucose
- Full blood count and ferritin
- Plasma metanephrines if episodic hypertension features
When to See a Doctor
See a doctor for a first panic attack to exclude cardiac, thyroid and metabolic causes. Seek emergency care for chest pain with exertion, pain radiating to the arm or jaw, fainting, or an irregular pulse. See a doctor sooner if attacks recur or you begin avoiding places.

Diet & Lifestyle
Suggested Pattern
No diet treats panic. Regular meals prevent hypoglycaemic symptoms that mimic and trigger attacks, and reducing caffeine and alcohol lowers baseline arousal.

Frequently Asked Questions
Who It Affects
Roughly 11% of adults experience a panic attack in any given year, while panic disorder affects around 2-3%, twice as often in women.
Quick Facts
- •Panic attacks peak within about ten minutes and are not physically dangerous
- •Hyperventilation causes the tingling and dizziness that fuel the fear loop
- •Avoidance behaviour, not the attack itself, converts panic into panic disorder
- •Interoceptive exposure in CBT has better durability than medication alone
Lifestyle Tips
- •Slow the out-breath rather than breathing deeply — over-breathing worsens symptoms
- •Do not leave the situation when an attack starts; leaving teaches avoidance
- •Cut caffeine, which lowers the threshold for attacks measurably
- •Avoid using alcohol to manage anxiety; withdrawal reliably triggers attacks
- •Seek CBT with interoceptive exposure specifically, not generic relaxation training
- •Maintain regular exercise, which reduces panic frequency and builds tolerance for arousal sensations
