What are the physical symptoms of anxiety

Anxiety is closely connected to the body’s stress response. When the brain senses danger, whether real or perceived, it triggers physical changes to help protect us.

Key points to understand:

• Anxiety triggers the body’s fight-or-flight response
• Stress hormones affect multiple body systems
• Physical symptoms are real, not imagined or made up

Common physical symptoms

Physical symptoms of anxiety can affect many parts of the body and may vary from person to person. Here are a few common physical symptoms:

1. Chest, heart, and breathing

• Tight or uncomfortable chest
• Racing or pounding heart
• Shortness of breath
• Feeling unable to take a deep breath
• Rapid breathing (hyperventilation), which may cause light-headedness or tingling

2. Digestive symptoms

• Nausea
• Stomach pain or cramps
• Bloating or reflux
• Changes in bowel habits
• Diarrhoea or constipation related to stress responses

3. Muscle and body sensations

• Muscle tension or aches
• Jaw clenching or teeth grinding
• Headaches
• Trembling or shaking

4. Neurological-type symptoms

• Dizziness or light-headedness
• Tingling or numbness
• Feeling “foggy” or disconnected

Amira, a registered psychotherapist, also adds: Depersonalisation or derealisation (a sense of feeling detached from oneself or surroundings) can be a symptom.

5. Sleep and energy changes

• Trouble falling or staying asleep
• Feeling tired but wired
• Persistent daytime fatigue

Why anxiety causes physical symptoms

Anxiety triggers the nervous system, preparing the body for action, even in situations when there is no immediate danger.

This can lead to:

• The release of adrenaline and other stress hormones
• Increased heart rate and muscle tension
• Slower digestion
• Greater sensitivity to physical sensations

Over time, these ongoing responses can feel constant and exhausting.

Anxiety vs physical illness

Anxiety-related symptoms	Physical illness
Come and go	Often more persistent or progressively worsening
Triggered by stress or worry	Triggered by disease
Improve with relaxation	Persist despite rest
Affects multiple body systems	Often localised

Important: Always seek medical review if symptoms are new, severe, or worrying.

When symptoms become a concern section

It’s important to get support if:

• Symptoms are persistent or worsening
• They interfere with work or daily life
• There’s a constant fear of serious illness
• Sleep is consistently disrupted
• Chest pain, fainting, severe shortness of breath, or other acute symptoms occur (urgent medical assessment may be required)

Note: If you experience sudden chest pain, difficulty breathing, or fainting, call 000 immediately or go to your nearest Emergency Department. Do not use telehealth for emergency medical concerns.
