Panic attacks & panic disorder | Symptoms & causes

August 3, 2026

A panic attack is a sudden surge of intense fear or overwhelming discomfort that can develop within minutes. During an episode, a person may feel as though they are having a heart attack, losing control, or even dying, despite there being no immediate physical danger.  Although panic attacks can be frightening, they are relatively common. Some people experience only one or two attacks during their lifetime, while others develop panic disorder, a condition characterized by recurrent panic attacks and persistent worry about having another one.

As a licensed Naturopathic Doctor and primary care healthcare provider with nearly 20 years of clinical experience, I have seen how disruptive panic attacks can be. Sometimes as a doctor, we need to put ourselves in the person's shoes to appreciate just how terrifying these episodes feel. Even when medical testing is normal, the symptoms are very real & they can significantly affect work, relationships, sleep & overall quality of life.

The encouraging news is that panic attacks and panic attack disorder are treatable. Understanding their symptoms, causes & available treatment options is the first step toward recovery.

What is a panic attack?

A panic attack is a sudden episode of intense fear accompanied by physical and emotional symptoms that usually reach their peak within several minutes.

Unlike normal anxiety, which often builds gradually in response to stress, panic attacks can occur unexpectedly and sometimes without an obvious trigger.

During a severe panic attack, many people believe they are experiencing a medical emergency because the symptoms can closely resemble those of a heart attack or other serious illness.

Panic attacks can occur on their own or as part of several conditions, including panic disorder, generalized anxiety disorder, post-traumatic stress disorder (PTSD), social anxiety disorder & certain medical conditions.

What is panic disorder?

Panic disorder is a recognized anxiety disorder involving recurrent, unexpected panic attacks combined with persistent concern about future attacks or changes in behaviour intended to avoid them.

For a diagnosis of panic disorder, the attacks are not simply caused by another medical condition, medication, or substance use.

People living with panic disorder may begin avoiding:

  • Driving
  • Shopping centres
  • Crowded places
  • Public transportation
  • Exercise
  • Being alone
  • Travelling
  • Social events

Over time, this avoidance can become more disabling than the panic attacks themselves.

Panic attack symptoms

The classic panic attack symptoms develop rapidly and may include:

  • Sudden overwhelming fear
  • Racing or pounding heart
  • Chest pain or tightness
  • Difficulty breathing
  • Feeling short of breath
  • Sweating
  • Trembling or shaking
  • Dizziness
  • Lightheadedness
  • Nausea
  • Chills
  • Hot flashes
  • Tingling in the hands or feet
  • Feeling detached from reality
  • Fear of losing control
  • Fear of dying

Not everyone experiences every symptom. Some people primarily notice physical symptoms, while others experience overwhelming emotional distress.

Through my education as a Naturopathic Doctor, I learned the textbook description of panic attacks. In practical clinical experience, however, I have observed that every individual experiences panic differently. Some become very quiet and withdrawn, while others feel an overwhelming urge to escape the situation immediately.

Signs of a panic attack

Recognizing the signs of a panic attack may help someone seek appropriate support sooner.

Visible signs may include:

  • Rapid breathing
  • Pale skin
  • Sweating
  • Trembling
  • Crying
  • Restlessness
  • Difficulty speaking
  • Looking frightened
  • Clutching the chest
  • Leaving a room suddenly
  • Feeling unable to remain still

Because many of these symptoms overlap with heart and lung conditions, anyone experiencing chest pain, shortness of breath, or a first episode of severe symptoms should be assessed medically.

Panic attack causes

There is rarely a single explanation for panic attack causes. Instead, panic attacks usually result from a combination of biological, psychological & environmental factors.

Potential contributors include:

  • Family history of anxiety disorders
  • Chronic stress
  • Major life changes
  • Trauma
  • Sleep deprivation
  • Excess caffeine
  • Certain medications
  • Recreational drug use
  • Thyroid disorders
  • Heart rhythm abnormalities
  • Hormonal changes
  • Other medical illnesses

In my opinion, panic attacks rarely occur "out of nowhere." Even when there is no obvious trigger, there are often underlying factors affecting the nervous system that deserve careful assessment.

 

What causes panic attacks?

Understanding what causes panic attacks requires recognizing that the body's natural fight-or-flight response becomes activated inappropriately.

Normally, this survival response protects us from danger.

During a panic attack, however, the brain reacts as though there is a life-threatening emergency even when no immediate danger exists.

This leads to:

  • Release of stress hormones
  • Increased heart rate
  • Rapid breathing
  • Muscle tension
  • Sweating
  • Heightened awareness
  • Digestive changes

Sometimes as a doctor, we need to understand the patient as more than a collection of symptoms. Poor sleep, chronic stress, unresolved trauma, excessive stimulants, hormonal changes & underlying medical conditions may all contribute to panic attacks.


Exhaustion induced panic attacks

One increasingly recognized trigger is exhaustion induced panic attacks.

Physical and emotional exhaustion may reduce the body's ability to regulate stress.

Contributors include:

  • Sleep deprivation
  • Burnout
  • Long work hours
  • Shift work
  • Parenting demands
  • Chronic illness
  • Overtraining
  • Emotional stress

When it comes to working professionals, I have observed that individuals often continue functioning despite months of inadequate sleep, excessive workloads & chronic stress. Eventually, the nervous system may become overwhelmed, increasing the likelihood of panic attacks.

Panic attack symptoms in Women

Hormonal shifts involving cortisol, estrogen, progesterone and thyroid hormones may influence anxiety in some individuals. Learn more about the connection between Hormones & Anxiety.

Some women notice worsening symptoms:

  • Before menstruation
  • During perimenopause
  • During menopause
  • Following childbirth
  • During periods of significant hormonal change

Possible symptoms include:

  • Rapid heartbeat
  • Chest tightness
  • Dizziness
  • Trembling
  • Shortness of breath
  • Intense fear
  • Nausea
  • Hot flashes
  • Feeling faint

Not all patients are equal based on age and gender because hormones, stress, previous trauma, sleep quality & overall health can influence how panic attacks present.

Anxiety attack symptoms in females

The phrase anxiety attack symptoms in females is commonly searched online.

  Although "anxiety attack" is not an official medical diagnosis, women experiencing intense anxiety may report:

  • Persistent worrying
  • Muscle tension
  • Difficulty concentrating
  • Trouble sleeping
  • Irritability
  • Racing thoughts
  • Digestive symptoms
  • Fatigue
  • Feeling overwhelmed

These symptoms generally develop more gradually than a panic attack.

Panic attack vs anxiety attack

Understanding panic attack vs anxiety attack can reduce confusion.

Panic Attack

Anxiety Attack

Recognized medical term

Informal term

Begins suddenly

Usually develops gradually

Peaks within minutes

Builds over time

Intense physical symptoms

Physical symptoms are usually milder

May occur without an obvious trigger

Usually linked to ongoing stress or worry

Fear of dying or losing control is common

Persistent worry is more common

Anxiety can contribute to panic attacks, but they are not the same condition.

Panic disorder symptoms

The most common panic disorder symptoms include:

  • Recurrent panic attacks
  • Fear of another attack
  • Avoiding certain places
  • Constant monitoring of bodily sensations
  • Difficulty concentrating
  • Sleep problems
  • Increased anxiety
  • Reduced quality of life

Some individuals begin avoiding exercise because an increased heart rate reminds them of previous panic attacks.

 

Heart symptoms during a panic attack

Many people worry that they are having a heart attack. 

Common heart associated symptoms women can experience during a panic attack include:

  • Racing heart
  • Palpitations
  • Chest pressure
  • Chest pain
  • Feeling that the heart is skipping beats

Although these symptoms commonly occur during panic attacks, they should never be automatically assumed to be anxiety.  New chest pain, severe shortness of breath, fainting, or symptoms suggestive of a heart attack require immediate medical assessment.

Risk factors

Factors that increase the likelihood of panic attacks include:

  • Family history
  • Anxiety disorders
  • Depression
  • PTSD
  • Chronic stress
  • Childhood adversity
  • High caffeine intake
  • Smoking
  • Certain medications
  • Sleep deprivation
  • Hyperthyroidism
  • Chronic illness

Over the years in my clinical practice I’ve observed that improving sleep quality, reducing stimulant intake, managing chronic stress & treating underlying medical conditions often become important parts of a comprehensive management plan for addressing panic attacks.

The naturopathic approach

Naturopathic Doctors evaluate both the physical and psychological contributors to anxiety and may develop a personalized Anxiety Treatment Plan based on the individual’s symptoms, health history and underlying factors.

Assessment may include:

  • Sleep quality
  • Nutrition
  • Caffeine intake
  • Alcohol use
  • Blood sugar regulation
  • Thyroid health
  • Iron status
  • Vitamin deficiencies
  • Hormonal health
  • Medication review
  • Stress levels
  • Trauma history
  • Exercise habits

We need to understand the patient deeply to provide holistic care. A comprehensive assessment helps determine whether symptoms are primarily related to panic disorder, another anxiety disorder, a medical condition, medication effects, or a combination of factors. Naturopathic care should complement not replace appropriate medical care, psychological therapy, or prescribed medications when indicated.

Lifestyle strategies that may help

Evidence-informed strategies that may support recovery include:

  • Prioritizing consistent sleep
  • Limiting caffeine
  • Regular physical activity
  • Stress management
  • Mindfulness-based practices
  • Slow diaphragmatic breathing
  • Balanced nutrition
  • Maintaining social support
  • Working with a qualified mental health professional

Recovery is often gradual & setbacks do not mean treatment has failed.

 

Final thoughts

Panic attacks can be frightening, but they are also highly treatable. Understanding the difference between a panic attack, panic disorder & ongoing anxiety can help individuals seek appropriate care and regain confidence in their daily lives.

As a wellness specialist, I believe recovery is most successful when we look beyond the panic attack itself. Sleep, nutrition, physical health, emotional well-being, stress management & appropriate psychological support all contribute to calming the nervous system. While panic attacks may feel overwhelming in the moment, effective treatments are available & with the right approach, many people experience significant improvement and return to the activities they enjoy.

FAQ’s

How long do panic attacks last?

Most panic attacks peak within approximately 10 minutes and usually resolve within 20 to 30 minutes, although some symptoms such as fatigue, shakiness, or heightened anxiety may continue for several hours afterward.

What causes panic attacks?

Panic attacks may result from an interaction between genetics, stress, trauma, medical conditions, hormonal changes, stimulant use, poor sleep & an overactive fight-or-flight response. Often, multiple factors contribute rather than a single identifiable cause.

What causes a panic attack?

A panic attack occurs when the body's survival response is activated despite there being no immediate danger. This causes a rapid release of stress hormones that produce symptoms such as a racing heart, chest tightness, dizziness, trembling & intense fear.

Is panic attack dangerous?

A panic attack itself is generally not life-threatening, but its symptoms can closely resemble serious medical conditions such as a heart attack or pulmonary embolism. Anyone experiencing chest pain, shortness of breath, fainting, or a first episode of severe symptoms should seek immediate medical assessment to rule out potentially dangerous causes.
