Getting panic attacks for no reason: what should you know?

A panic attack is a sudden surge of fear or alarm that can cause a racing or pounding heart, chest tightness, fast breathing, trembling, sweating, dizziness, or numbness and tingling. The body’s alarm system can activate when you do not consciously recognise a trigger. Panic disorder is one possible explanation, but similar symptoms can occur with heart, breathing, thyroid or medicine-related problems. Feeling anxious between episodes, avoiding places, or constantly fearing another attack is useful information for a clinician.

If you can, stay where you are and sit with your feet supported. Breathe gently, making the out-breath slightly longer than the in-breath, and name a few things you can see and feel. Remind yourself that the sensations are an alarm response, while still taking new or unusual symptoms seriously. Between episodes, record timing, symptoms, sleep, caffeine, medicines and possible situations. A GP consultation or mental health assessment can clarify the pattern and guide treatment.

Get urgent medical help for severe or persistent chest pain, fainting, marked breathing difficulty, new weakness, confusion or symptoms that feel different from previous attacks. Seek immediate help if panic is accompanied by thoughts of self-harm or you cannot stay safe. Book a routine appointment when attacks recur, disrupt sleep or travel, or lead you to avoid normal activities.

Ask whether your symptoms need physical checks, how to distinguish panic from other causes, and which psychological or medication options fit your health history. Mention substances, supplements and recent changes in medicines.
