What should you know about blackout anxiety?

During intense fear, breathing may become fast or shallow. This can change carbon dioxide levels and produce tingling, light-headedness, tunnel vision, or a sense that you will lose control. Anxiety can also trigger sweating, a pounding heart, muscle tension, and an urge to sit down. These sensations can be frightening without proving that anxiety is the only cause.

A person can also have anxiety after a frightening faint, creating a cycle of body scanning and fear of another episode. Anaemia, Dehydration, Hypoglycaemia, and Atrial Fibrillation can produce overlapping symptoms, so the distinction should be based on the episode and an examination rather than assumption.

Sit or lie down somewhere safe, loosen restrictive clothing, and breathe slowly with a comfortable pause between breaths. Focus on a fixed object and ask someone to stay nearby. Once fully alert, take small sips of fluid and avoid standing suddenly. Keep a record of the setting, trigger, warning symptoms, pulse sensation, food and drink, and whether you actually lost awareness. Arrange a check-up if episodes are new, recurrent, or unexplained.

Get emergency help for actual loss of consciousness with chest pain, severe breathlessness, a new neurological symptom, an injury, prolonged confusion, or failure to wake promptly. Seek urgent assessment if the event occurred during exercise, while lying down, or with a sustained irregular heartbeat. Do not label an episode as anxiety when the physical pattern has changed.

Ask how to distinguish panic symptoms from fainting, whether your blood pressure, heart rhythm, glucose, or blood count needs checking, and whether counselling or breathing practice could help. Share any medicines, stimulant use, sleep disruption, and recent stressors.
